We investigated the perception of developmental changes in timing patterns that happen in the course of second language (L2) acquisition, provided that the native and the target languages of the learner are rhythmically similar (German and English). It was found that speech rhythm in L2 English produced by German learners becomes increasingly stress-timed as acquisition progresses. This development is captured by the tempo-normalized rhythm measures of durational variability. Advanced learners also deliver speech at a faster (...) rate. However, when native speakers have to classify the timing patterns characteristic of L2 English of German learners at different proficiency levels, they attend to speech rate cues and ignore the differences in speech rhythm.

We present a test of a revised version of the Second Language Linguistic Perception (L2LP) model, a computational model of the acquisition of second language (L2) speech perception and recognition. The model draws on phonetic, phonological and psycholinguistic constructs to explain a number of L2 learning scenarios. However, a recent computational implementation failed to validate a theoretical proposal for a learning scenario where the L2 has less phonemic categories than the native language (...) (L1) along a given acoustic continuum. According to the L2LP, learners faced with this learning scenario must not only shift their old L1 phoneme boundaries but also reduce the number of categories employed in perception. Our proposed revision to L2LP successfully accounts for this updating in the number of perceptual categories as a process driven by the meaning of lexical items, rather than by the learners’ awareness of the number and type of phonemes that are relevant in their new language, as the previous version of L2LP assumed. Results of our simulations show that meaning-driven learning correctly predicts the developmental path of L2 phoneme perception seen in empirical studies. Additionally, and to contribute to a long-standing debate in psycholinguistics, we test two versions of the model, with the stages of phonemic perception and lexical recognition being either sequential or interactive. Both versions succeed in learning to recognize minimal pairs in the new L2, but make diverging predictions on learners' resulting phonological representations. In sum, the proposed revision to the L2LP model contributes to our understanding of L2 acquisition, with implications for speech processing in general. (shrink)

Speech variability facilitates non-tonal language speakers’ lexical tone learning. However, it remains unknown whether tonal language speakers can also benefit from speech variability while learning second language (L2) lexical tones. Researchers also reported that the effectiveness of speech variability was only shown on learning new items. Considering that the first language (L1) and L2 probably share similar tonal categories, the present study hypothesizes that speech variability only promotes the tonal language (...) speakers’ acquisition of L2 tones that are different from the tones in their L1. To test this hypothesis, the present study trained native Mandarin (a tonal language) speakers to learn Cantonese tones with either high variability (HV) or low variability (LV) speech materials, and then compared their learning performance. The results partially supported this hypothesis: only Mandarin subjects’ productions of Cantonese low level and mid level tones benefited from the speech variability. They probably relied on the mental representations in L1 to learn the Cantonese tones that had similar Mandarin counterparts. This learning strategy limited the impact of speech variability. Furthermore, the results also revealed a discrepancy between L2 perception and production. The perception improvement may not necessarily lead to an improvement in production. (shrink)

Previous research suggests that mastering languages with distinct rather than similar rhythmic properties enhances musical rhythmic perception. This study investigates whether learning a second language (L2) enhances the perception of musical rhythmic variation in general, regardless of first and second languages’ rhythmic properties. Additionally, we investigated whether this perceptual enhancement could be alternatively explained by exposure to musical rhythmic complexity, such as the use of compound meter in Turkish music. Finally, it investigates if an enhancement (...) of musical rhythmic perception could be observed among L2 learners whose first language relies heavily on pitch information, as is the case with tonal languages. Therefore, we tested Turkish, Dutch and Mandarin L2 learners of English and Turkish monolinguals on their ability to perceive musical rhythmic variation. Participants’ phonological and working memory capacities, melodic aptitude, years of formal musical training and daily exposure to music were assessed to account for cultural and individual differences which could impact their rhythmic ability. Our results suggest that mastering a second language rather than exposure to musical rhythmic complexity could explain individuals’ enhanced perception of musical rhythmic variation. An even stronger enhancement of musical rhythmic perception was observed for L2 learners whose first and second languages differ regarding their rhythmic properties, as enhanced performance of Mandarin and Turkish in comparison with Dutch L2 learners of English seem to suggest. Our findings provide further support for a cognitive transfer between the language and music domain, which may find its grounds on a common evolutionary basis. (shrink)

Lateral temporal measures of the auditory evoked potential including the T-complex, as well as an earlier negative peak index maturation of auditory/speech processing. Previous studies have shown that these measures distinguish neural processing in children with typical language development from those with disorders and monolingual from bilingual children. In this study, bilingual children with Turkish as L1 and German as L2 were compared with monolingual German-speaking children with developmental language disorder and monolingual German-speaking children with TD in (...) order to disentangle effects of limited language input vs. reduced perceptual abilities in the processing of speech and non-speech stimuli. Sensory processing reflected by the T-complex was compared in response to a German vowel and a sine-wave tone in the three groups of children, ages 5 through 6 years. Stimuli were presented while children watched a muted video. Auditory evoked potentials were time-locked to the vowels and tones. AEPs to the frequent stimuli within an oddball paradigm were analyzed at the left and right temporal electrode sites.The results revealed language status, stimulus, and language test measures all influenced the T-complex amplitudes. Particularly, the peak amplitude of Ta was modulated by language status and stimulus type. Bilingual children had significantly more negative Ta responses than the monolingual children with TD for both vowels and tones while DLD children differed from TD children only for the vowel stimulus. The amplitude of the T-complex was overall more negative at the left than at the right site. The Na peak latency was longer for the bilingual group than that observed for the two monolingual groups. The Tb latency was shorter for DLD and bilingual groups than that for TD children in the vowel condition, but no such latency difference between DLD and bilingual children was found. We suggest that the attenuated T-complex for bilingual children indicates continued plasticity of the auditory cortex to allow for learning of novel, second-language speech sounds. (shrink)

Although speech categories are defined by multiple acoustic dimensions, some are perceptually weighted more than others and there are residual effects of native-language weightings in non-native speech perception. Recent research on nonlinguistic sound category learning suggests that the distribution characteristics of experienced sounds influence perceptual cue weights: Increasing variability across a dimension leads listeners to rely upon it less in subsequent category learning (Holt & Lotto, 2006). The present experiment investigated the implications of this among native (...) Japanese learning English /r/-/l/ categories. Training was accomplished using a videogame paradigm that emphasizes associations among sound categories, visual information, and players’ responses to videogame characters rather than overt categorization or explicit feedback. Subjects who played the game for 2.5 h across 5 days exhibited improvements in /r/-/l/ perception on par with 2–4 weeks of explicit categorization training in previous research and exhibited a shift toward more native-like perceptual cue weights.

Temporal regularities in speech, such as interdependencies in the timing of speech events, are thought to scaffold early acquisition of the building blocks in speech. By providing on-line clues to the location and duration of upcoming syllables, temporal structure may aid segmentation and clustering of continuous speech into separable units. This hypothesis tacitly assumes that learners exploit predictability in the temporal structure of speech. Existing measures of speech timing tend to focus on first-order regularities (...) among adjacent units, and are overly sensitive to idiosyncrasies in the data they describe. Here, we compare several statistical methods on a sample of 18 languages, testing whether syllable occurrence is predictable over time. Rather than looking for differences between languages, we aim to find across languages (using clearly defined acoustic, rather than orthographic, measures), temporal predictability in the speech signal which could be exploited by a language learner. First, we analyse distributional regularities using two novel techniques: a Bayesian ideal learner analysis, and a simple distributional measure. Second, we model higher-order temporal structure—regularities arising in an ordered series of syllable timings—testing the hypothesis that non-adjacent temporal structures may explain the gap between subjectively-perceived temporal regularities, and the absence of universally-accepted lower-order objective measures. Together, our analyses provide limited evidence for predictability at different time scales, though higher-order predictability is difficult to reliably infer. We conclude that temporal predictability in speech may well arise from a combination of individually weak perceptual cues at multiple structural levels, but is challenging to pinpoint. (shrink)

Perception of music and speech is based on similar auditory skills, and it is often suggested that those with enhanced music perception skills may perceive and learn novel words more easily. The current study tested whether music perception abilities are associated with novel word learning in an ambiguous learning scenario. Using a cross-situational word learning (CSWL) task, nonmusician adults were exposed to word-object pairings between eight novel words and visual referents. Novel words were either non-minimal pairs (...) differing in all sounds or minimal pairs differing in their initial consonant or vowel. In order to be successful in this task, learners need to be able to correctly encode the phonological details of the novel words and have sufficient auditory working memory to remember the correct word-object pairings. Using the Mistuning Perception Test (MPT) and the Melodic Discrimination Test (MDT), we measured learners’ pitch perception and auditory working memory. We predicted that those with higher MPT and MDT values would perform better in the CSWL task and in particular for novel words with high phonological overlap (i.e., minimal pairs). We found that higher musical perception skills led to higher accuracy for non-minimal pairs and minimal pairs differing in their initial consonant. Interestingly, this was not the case for vowel minimal pairs. We discuss the results in relation to theories of second language word learning such as the Second Language Perception model (L2LP).

Research on bilingualism has grown exponentially in recent years. However, the comprehension of speech in noise, given the ubiquity of both bilingualism and noisy environments, has seen only limited focus. Electroencephalogram studies in monolinguals show an increase in alpha power when listening to speech in noise, which, in the theoretical context where alpha power indexes attentional control, is thought to reflect an increase in attentional demands. In the current study, English/French bilinguals with similar second language proficiency (...) and who varied in terms of age of L2 acquisition from 0 to 15 years completed a speech perception in noise task. Participants were required to identify the final word of high and low semantically constrained auditory sentences such as “Stir your coffee with a spoon” vs. “Bob could have known about the spoon” in both of their languages and in both noise and quiet during electrophysiological recording. We examined the effects of language, AoA, semantic constraint, and listening condition on participants’ induced alpha power during speech comprehension. Our results show an increase in alpha power when participants were listening in their L2, suggesting that listening in an L2 requires additional attentional control compared to the first language, particularly early in processing during word identification. Additionally, despite similar proficiency across participants, our results suggest that under difficult processing demands, AoA modulates the amount of attention required to process the second language.

Evolutionary developmental systems theory stresses that selection pressures operate on entire developmental systems rather than just genes. This study extends this approach to language evolution, arguing that selection pressure may operate on two quasi-independent timescales. First, children clearly must acquire language successfully and evolution must equip them with the tools to do so. Second, while this is developing, they must also communicate with others in the moment using partially developed knowledge. These pressures may require different solutions, and (...) their combination may underlie the evolution of complex mechanisms for language development and processing. I present two case studies to illustrate how the demands of both real-time communication and language acquisition may be subtly different. The first case study examines infant-directed speech. A recent view is that IDS underwent cultural to statistical learning mechanisms that infants use to acquire the speech categories of their language. However, recent data suggest is it may not have evolved to enhance development, but rather to serve a more real-time communicative function. The second case study examines the argument for seemingly specialized mechanisms for learning word meanings. Both behavioral and computational work suggest that learning may be much slower and served by general-purpose mechanisms like associative learning. Fast-mapping, then, may be a real-time process meant to serve immediate communication, not learning, by augmenting incomplete vocabulary knowledge with constraints from the current context. Together, these studies suggest that evolutionary accounts consider selection pressure arising from both real-time communicative demands and from the need for accurate language development. (shrink)

Because human languages vary in sound and meaning, children must learn which distinctions their language uses. For speech perception, this learning is selective: initially infants are sensitive to most acoustic distinctions used in any language1–3, and this sensitivity reflects basic properties of the auditory system rather than mechanisms specific to language4–7; however, infants’ sensitivity to non-native sound distinctions declines over the course of the first year8. Here we ask whether a similar process governs learning of word meanings. (...) We investigated the sensitivity of 5-month-old infants in an English-speaking environment to a conceptual distinction that is marked in Korean but not English; that is, the distinction between ‘tight’ and ‘loose’ fit of one object to another9,10. Like adult Korean speakers but unlike adult English speakers, these infants detected this distinction and divided a continuum of motion-into-contact actions into tightand loose-fit categories. Infants’ sensitivity to this distinction is linked to representations of object mechanics11that are shared by non-human animals12–14. Language learning therefore seems to develop by linking linguistic forms to universal, pre-existing representations of sound and meaning. Our research focuses on the crosscutting conceptual distinctions between actions producing loose- and tight-fitting contact relationships (compare left and right columns in Fig. 1a) and actions producing containment versus support relationships (compare first and second rows in Fig. 1a). As early as Korean and English children begin to talk about such actions, they categorize them differently from one another and similarly to Korean- and Englishspeaking adults9,15. Moreover, English and Korean adults differ in their performance on non-linguistic categorization tasks involving heterogeneous examples of these actions, in accord with the differing semantics of their languages16,17, whereas the performance of young children on such tasks has been mixed9,10,18,19..

In this contribution we will approach language and images in different modalities: speech and face, anticipated and imagined movements, illusions on the sound by the image. It will be the opportunity for us to revisit the Gestalt concepts which were considered obsolete since structuralism in Humanities. As instantiated by Gilbert Durand in The Anthropological Structures of the Imaginary (1999, French 1st ed. 1960), we shall recall that Gestalt is not—even implicitly—an exclusively static approach to cognition. On the contrary (...) we will emphasize that forms can emerge from movements and stabilize in memory, thence morphology. And for speech, we will consider phonology as the stabilized outcome from audible and visible gestures of the mouth—caught in the time-course of a flow of some four in six syllables by second—via the perception of motor coordinations: which is necessary to master the most common expression of language between humans. We will adopt here also for the perceptual flows of spoken language, Multimodal Scene Analysis, the ongoing legacy of Gestalt Theory, including one of our main research topics: the gestural expression of the face and the hand for Deaf people, who practise as an augment French LPC (Langue française Parlée Complétée), adapted in 1967 from Cued Speech by its originator Dr Richard Cornett.

Speech is intelligible even when the temporal envelope of speech is distorted. The current study investigates how native and non-native speakers perceptually restore temporally distorted speech. Participants were native English speakers (NS), and native Japanese speakers who spoke English as a second language (NNS). In Experiment 1, participants listened to “locally time-reversed speech” where every x-ms of speech signal was reversed on the temporal axis. Here, the local time reversal shifted the constituents of (...) the speech signal forward or backward from the original position, and the amplitude envelope of speech was altered as a function of reversed segment length. In Experiment 2, participants listened to “modulation-filtered speech” where the modulation frequency components of speech were low-pass filtered at a particular cut-off frequency. Here, the temporal envelope of speech was altered as a function of cut-off frequency. The results suggest that speech becomes gradually unintelligible as the length of reversed segments increases (Experiment 1), and as a lower cut-off frequency is imposed (Experiment 2). Both experiments exhibit the equivalent level of speech intelligibility across six levels of degradation for native and non-native speakers respectively, which poses a question whether the regular occurrence of local time reversal can be discussed in the modulation frequency domain, by simply converting the length of reversed segments (ms) into frequency (Hz).

Is speech special? This paper evaluates the evidence that speech perception is distinctive when compared with non-linguistic auditory perception. It addresses the phenomenology, contents, objects, and mechanisms involved in the perception of spoken language. According to the account it proposes, the capacity to perceive speech in a manner that enables understanding is an acquired perceptual skill. It involves learning to hear language-specific types of ethologically significant sounds. According to this account, the contents (...) of perceptual experience when listening to familiar speech are of a variety that is distinctive to hearing spoken utterances. However, perceiving speech involves neither novel perceptual objects nor a unique perceptual modality. Much of what makes speech special stems from our interest in it. (shrink)

This article concerns sound aesthetic preferences for European foreign languages. We investigated the phonetic-acoustic dimension of the linguistic aesthetic pleasure to describe the “music” found in European languages. The Romance languages, French, Italian, and Spanish, take a lead when people talk about melodious language – the music-like effects in the language (a.k.a., phonetic chill). On the other end of the melodiousness spectrum are German and Arabic that are often considered sounding harsh and un-attractive. Despite the public interest, limited (...) research has been conducted on the topic of phonaesthetics, i.e., the subfield of phonetics that is concerned with the aesthetic properties of speech sounds (Crystal, 2008). Our goal is to fill the existing research gap by identifying the acoustic features that drive the auditory perception of language sound beauty. What is so music-like in the language that makes people say “it is music in my ears”? We had 45 central European participants listening to 16 auditorily presented European languages and rating each language in terms of 22 binary characteristics (e.g., beautiful – ugly and funny – boring) plus indicating their language familiarities, L2 backgrounds, speaker voice liking, demographics, and musicality levels. Findings revealed that all factors in complex interplay explain a certain percentage of variance: familiarity and expertise in foreign languages, speaker voice characteristics, phonetic complexity, musical acoustic properties, and finally musical expertise of the listener. The most important discovery was the trade-off between speech tempo and so-called linguistic melody (pitch variance): the faster the language, the flatter/more atonal it is in terms of the pitch (speech melody), making it highly appealing acoustically (sounding beautiful and sexy), but not so melodious in a “musical” sense.

In the first year of life, infants' speech perception becomes attuned to the sounds of their native language. This process of early phonetic learning has traditionally been framed as phonetic category acquisition. However, recent studies have hypothesized that the attunement may instead reflect a perceptual space learning process that does not involve categories. In this article, we explore the idea of perceptual space learning by implementing five different perceptual space learning models and testing them on three phonetic (...) contrasts that have been tested in the infant speech perception literature. We reproduce and extend previous results showing that a perceptual space learning model that uses only distributional information about the acoustics of short time slices of speech can account for at least some crosslinguistic differences in infant perception. Moreover, we find that a second perceptual space learning model, which benefits from word‐level guidance. performs equally well in capturing crosslinguistic differences in infant speech perception. These results provide support for the general idea of perceptual space learning as a theory of early phonetic learning but suggest that more fine‐grained data are needed to distinguish between different formal accounts. Finally, we provide testable empirical predictions of the two most promising models and show that these are not identical, making it possible to independently evaluate each model in experiments with infants in future research.

Developmental dyslexia is considered to be most effectively addressed with preventive phonics-based interventions, including grapheme-phoneme coupling and blending exercises. These intervention types require intact speech perception abilities, given their large focus on exercises with auditorily presented phonemes. Yet some children with dyslexia experience problems in this domain due to a poorer sensitivity to rise times, i.e., rhythmic acoustic cues present in the speech envelope. As a result, the often subtle speech perception problems could potentially constrain (...) an optimal response to phonics-based interventions in at-risk children. The current study therefore aimed to extend existing research by examining the presence of potential speech perception deficits in pre-readers at cognitive risk for dyslexia when compared to typically developing peers and to explore the added value of a preventive auditory intervention for at-risk pre-readers, targeting rise time sensitivity, on speech perception and other reading-related skills. To obtain the first research objective, we longitudinally compared speech-in-noise perception between 28 5-year-old pre-readers with and 30 peers without a cognitive risk for dyslexia during the second half of the third year of kindergarten. The second research objective was addressed by exploring growth in speech perception and other reading-related skills in an independent sample of 62 at-risk 5-year-old pre-readers who all combined a 12-week preventive phonics-based intervention with an auditory story listening intervention. In half of the sample, story recordings contained artificially enhanced rise times, while in the other half, stories remained unprocessed. Results revealed a slower speech-in-noise perception growth in the at-risk compared to the non-at-risk group, due to an emerged deficit at the end of kindergarten. Concerning the auditory intervention effects, both intervention groups showed equal growth in speech-in-noise perception and other reading-related skills, suggesting no boost of envelope-enhanced story listening on top of the effect of combining GraphoGame-Flemish with listening to unprocessed stories. These findings thus provide evidence for a link between speech perception problems and dyslexia, yet do not support the potential of the auditory intervention in its current form. (shrink)

Due to the implementation of global education and global citizenship education in the 21st century, more focus is given to developing teachers’ global competence in English language teaching. This study aims to examine the perceptions of English as a Second Language teachers of global competence integration in English teaching and the professional development programs organized by the Ministry of Education for their global competence development. A web-survey questionnaire was distributed to 172 Malaysian ESL teachers based on selected (...) criteria. The data collected were analyzed descriptively. The main findings indicated that most ESL teachers showed positive perceptions regarding the importance of global competence and integration in English lessons. Although 83.1% of the 172 participants agreed to have attended 10 or more programs related to developing global competence, the descriptive analysis found the ESL teachers’ moderate knowledge and understanding of what constitutes global competence. In contrast, a high agreement was found regarding their perceptions of the importance of global competence in ESL lessons. Also, most respondents revealed the lack of support from the MOE through professional development programs specifically structured to develop ESL teachers’ global competence. The findings served as a template for a larger-scale study that focuses on implementing global competence in the local non-western context. (shrink)

Speech recognition by second language (L2) learners in optimal and suboptimal conditions has been examined extensively with English as the target language in most previous studies. This study extended existing experimental protocols ( Wang et al., 2013 ) to investigate Mandarin speech recognition by Japanese learners of Mandarin at two different levels (elementary vs. intermediate) of proficiency. The overall results showed that in addition to L2 proficiency, semantic context, F0 contours, and listening condition all affected (...) the recognition performance on the Mandarin sentences. However, the effects of semantic context and F0 contours on L2 speech recognition diverged to some extent. Specifically, there was significant modulation effect of listening condition on semantic context, indicating that L2 learners made use of semantic context less efficiently in the interfering background than in quiet. In contrast, no significant modulation effect of listening condition on F0 contours was found. Furthermore, there was significant interaction between semantic context and F0 contours, indicating that semantic context becomes more important for L2 speech recognition when F0 information is degraded. None of these effects were found to be modulated by L2 proficiency. The discrepancy in the effects of semantic context and F0 contours on L2 speech recognition in the interfering background might be related to differences in processing capacities required by the two types of information in adverse listening conditions.

The review gives an introductory description of the successive development of data patterns based on comparisons between hearing-impaired and normal hearing participants’ speech understanding skills, later prompting the formulation of the Ease of Language Understanding model. The model builds on the interaction between an input buffer and three memory systems: working memory, semantic long-term memory, and episodic long-term memory. RAMBPHO input may either match or mismatch multimodal SLTM representations. Given a match, lexical access is accomplished rapidly and implicitly (...) within approximately 100–400 ms. Given a mismatch, the prediction is that WM is engaged explicitly to repair the meaning of the input – in interaction with SLTM and ELTM – taking seconds rather than milliseconds. The multimodal and multilevel nature of representations held in WM and LTM are at the center of the review, being integral parts of the prediction and postdiction components of language understanding. Finally, some hypotheses based on a selective use-disuse of memory systems mechanism are described in relation to mild cognitive impairment and dementia. Alternative speech perception and WM models are evaluated, and recent developments and generalisations, ELU model tests, and boundaries are discussed. (shrink)

At first blush, phenomenology seems to be concerned preeminently with questions of knowledge, truth, and perception, and yet closer inspection reveals that the analyses of these phenomena remain bound up with language and that consequently phenomenology is, inextricably, a philosophy of language. Drawing on the insights of a variety of phenomenological authors, including Husserl, Heidegger, Merleau-Ponty, Gadamer, and Ricoeur, this collection of essays by leading scholars articulates the distinctively phenomenological contribution to language by examining two sets (...) of questions. The first set of questions concerns the relatedness of language to experience. Studies exhibit the first-person character of the philosophy of language by focusing on lived experience, the issue of reference, and disclosive speech. The second set of questions concerns the relatedness of language to intersubjective experience. Studies exhibit the second-person character of the philosophy of language by focusing on language acquisition, culture, and conversation. This book will be of interest to scholars of phenomenology and philosophy of language. (shrink)

Most language learners have difficulties acquiring the phonemes of a second language (L2). Unfortunately, they are often judged on their L2 pronunciation, and segmental inaccuracies contribute to miscommunication. Therefore, we aim to determine how to facilitate phoneme acquisition. Given the close relationship between speech and co-speech gesture, previous work unsurprisingly reports that gestures can benefit language acquisition, e.g., in (L2) word learning. However, gesture studies on L2 phoneme acquisition present contradictory results, implying that both (...) specific properties of gestures and phonemes used in training, and their combination, may be relevant. We investigated the effect of phoneme and gesture complexity on L2 phoneme acquisition. In a production study, Dutch natives received instruction on the pronunciation of two Spanish phonemes, /u/ and /θ/. Both are typically difficult to produce for Dutch natives because their orthographic representation differs between both languages. Moreover, /θ/ is considered more complex than /u/, since the Dutch phoneme inventory contains /u/ but not /θ/. The instruction participants received contained Spanish examples presented either via audio-only, audio-visually without gesture, audio-visually with a simple, pointing gesture, or audio-visually with a more complex, iconic gesture representing the relevant speech articulator(s). Preceding and following training, participants read aloud Spanish sentences containing the target phonemes. In a perception study, Spanish natives rated the target words from the production study on accentedness and comprehensibility. Our results show that combining gesture and speech in L2 phoneme training can lead to significant improvement in L2 phoneme production, but both gesture and phoneme complexity affect successful learning: Significant learning only occurred for the less complex phoneme /u/ after seeing the more complex iconic gesture, whereas for the more complex phoneme /θ/, seeing the more complex gesture actually hindered acquisition. The perception results confirm the production findings and show that items containing /θ/ produced after receiving training with a less complex pointing gesture are considered less foreign-accented and more easily comprehensible as compared to the same items after audio-only training. This shows that gesture can facilitate task performance in L2 phonology acquisition, yet complexity affects whether certain gestures work better for certain phonemes than others. (shrink)

Spoken word recognition involves a perceptual tradeoff between the reliance on the incoming acoustic signal and knowledge about likely sound categories and their co-occurrences as words. This study examined how adult second language (L2) learners navigate between acoustic-based and knowledge-based spoken word recognition when listening to highly variable, multi-talker truncated speech, and whether this perceptual tradeoff changes as L2 listeners gradually become more proficient in their L2 after multiple months of structured classroom learning. First language (L1) (...) Mandarin Chinese listeners and L1 English-L2 Mandarin adult listeners took part in a gating experiment. The L2 listeners were tested twice—once at the start of their intermediate/advanced L2 language class and again two months later. L1 listeners were only tested once. Participants were asked to identify syllable-tone words that varied in syllable token frequency (high/low according to a spoken word corpus) and syllable-conditioned tonal probability (most probable/least probable in speech given the syllable). The stimuli were recorded by 16 different talkers and presented at eight gates ranging from onset-only (gate 1) through onset+40 ms increments (gates 2 through 7) to the full word (gate 8). Mixed-effects regression modeling was used to compare performance to our previous study which used single-talker stimuli (Wiener, Lee, & Tao, 2019). The results indicated that multi-talker speech caused both L1 and L2 listeners to rely greater on knowledge-based processing of tone. L1 listeners were able to draw on distributional knowledge of syllable-tone probabilities in early gates and switch to predominantly acoustic-based processing when more of the signal was available. In contrast, L2 listeners, with their limited experience with talker range normalization, were less able to effectively transition from probability-based to acoustic-based processing. Moreover, for the L2 listeners, the reliance on such distributional information for spoken word recognition appeared to be conditioned by the nature of the acoustic signal. Single-talker speech did not result in the same pattern of probability-based tone processing, suggesting that knowledge-based processing of L2 speech may only occur under certain acoustic conditions, such as multi-talker speech.

In his Encomium of Helen and On Not Being, Gorgias of Leontinoi discusses the nature and function of speech more extensively than any other surviving author before Plato. His discussions are not only surprising in the way they characterize the power of logos and its effects on a listener but also in how the two descriptions of speech seem to contradict one another. In the Helen, Gorgias claims that logos is a very powerful entity, capable of affecting a (...) listener in whatever way it wants. In On Not-Being, he makes the very different (but no less exaggerated) claim that logos is a non-entity, incapable of referring to anything other than itself. In this essay I show how these apparently contradictory accounts might be brought into harmony with one another.2 In the first part I address some of the interpretive difficulties with the text of Gorgias’s On Not Being (henceforth ONB) and the role that irony plays in the work. In particular I argue (as others have before) that Gorgias’s remarks about the impotency of speech are not meant to be taken seriously. Instead, they are aimed more squarely at raising questions about how exactly speech is thought to function and, more specifically, how linguistic reference works—i.e., how words somehow correspond to things, on one level, and to our ideas about things, on another. In the second and third parts of this paper, I illustrate how Gorgias’s concern with linguistic reference in ONB goes on to inform his notion of logos in the Encomium of Helen. I point specifically to evidence found in an important and often overlooked exit clause at the close of ONB regarding the difference between words and things. There, Gorgias insists that if words manifest meaning at all, they must appeal to their own sort of sense organ. In the Helen, he draws on the concepts of soul (psychē) and opinion (doxa) in order to construct this alternative, psychagogic account in which utterances are actually apprehended in ways akin to sense perception. Whether or not one is convinced by Gorgias’s alternative account of how speech works, the description he gives of logos does notionally circumvent the problem of linguistic reference and, in doing so, pushes one to think beyond the potentially constrictive framework of nomen et nominatum. I argue that, when read in this way, these two early discussions of logos represent a unified progression of serious thought about how speech works. (shrink)

This paper deals with the treatment of figures of speech in Perelman’s and Olbrechts-Tyteca’s Treatise on Argumentation (TA), and, more broadly, with the place of figures in argumentation theory. The contrast between two conceptions (or two domains)\n of rhetoric, “a rhetoric of figures” and “a rhetoric of argument” can be traced back to Ramus, and it has been revived in\n the seventies through the perception of an incommensurability between Perelman’s “New Rhetoric” and the École de Liège’s “General\n Rhetoric”. (...) Modern theories of argumentation, oriented towards the characterization and denunciation of fallacious discourse,\n emphasize the gap between sound argumentative discourse and rhetorical discourse seen as a “powerful instrument of error and\n deceit” (Locke). This concept of argument presupposes a vision of language as ideal/transparent—a revised language that is\n not the language of ordinary argumentation. Figures are not basically “decorative”; they are manifestations of the complex\n process of language structuring in speech. Thus rejecting figures amounts to a negation of discourse as such. The second section\n turns to a somewhat neglected aspect of the TA, its both decisive and somewhat cavalier theory of figures of speech, and its extended use and re-definition of a complex set of figures. We argue that the TA, in its quest for descriptive adequacy, breaks with the traditional and comfortable concept of figures as useless fallacious\n “ornaments” and provides us with the first description of what could be characterized as the semantic level of ordinary argumentative\n discourse. This will be shown on the case of “figures of choice, presence and communion”, and could be extended to the discursive\n construction of objects and participants, including the speaker and her emotions.

The overall goal of speech perception research is to explain how spoken language is recognized and understood. In the current research framework it is assumed that the key to achieving this overall goal is to solve the lack of invariance problem. But nearly half a century of sustained effort in a variety of theoretical perspectives has failed to solve this problem. Indeed, not only has the problem not been solved, virtually no empirical candidates for solving the problem (...) have been produced. One explanation for this lack of progress is simply that no theory has yet hit upon the correct set of invariant properties. Another explanation is that the goal of solving the lack of invariance problem is itself misguided. The most basic claim of this dissertation is that the latter explanation is correct. ;The lack of progress in explaining speech perception exhibited by the current research framework, I argue, is not, in the first instance, due to the failure of individual theories to solve the lack of invariance problem, but rather to the common background assumption that doing so is in fact the key to explaining speech perception. ;My overall argument in support of this basic claim has three main components: criticism of the empirical results of research in the current framework; criticism of the formulation of theories generated in the current research framework; and the availability of an alternative account of phonetic structure. ;The heart of my argument is an analysis of the character of the theoretical weaknesses of three theories of speech perception: the motor theory of speech perception, the ecological theory of speech perception, and the theory of acoustic invariance. I show that, in each case, the particular theoretical problems result from trying to satisfy the common goal of identifying invariant properties of phonetic percepts. ;I analyze the methodological error embodied in the current approach to explaining speech perception as, in general, one of abstracting the wrong kinds of properties from the detail of the speech event, and, in particular, of abstracting away from dynamic and context-dependent properties.

Recent years have seen recurring episodes of tension between proponents of freedom of speech and advocates of the disenfranchised. Recent survey research attests to the ideological division in attitudes toward free speech, whereby conservatives report greater support for free speech than progressives do. Intrigued by the question of whether “canceling” is indeed a uniquely progressive tendency, we conducted a vignette-based experiment examining judgments of offensiveness among progressives and conservatives. Contrary to the dominant portrayal of progressives and conservatives, (...) our study documented ideological symmetry in their evaluations of offensive speech. When faced with utterances whose content matters to them, both conservatives and progressives viewed outgroup speakers as more offensive than ingroup speakers. A second contribution of this chapter is to provide a deeper understanding of the cognitive mechanism implicated in evaluating outgroup speech as more offensive than ingroup speech. Our results suggest that perception of offensiveness is mediated by ascriptions of intent: we tend to attribute negative intent to the speaker whenever we deem their utterances to be offensive, even against the explicitly stated speaker’s background attitudes.

Non-native listeners deal with adverse listening conditions in their daily life much harder than native listeners. However, previous work in our laboratories found that native Chinese listeners with native English exposure may improve the use of temporal fluctuations of noise for English vowel identification. The purpose of this study was to investigate whether Chinese listeners can generalize the use of temporal cues for the English sentence recognition in noise. Institute of Electrical and Electronics Engineers sentence recognition in quiet condition, stationary (...) noise, and temporally-modulated noise were measured for native American English listeners, native Chinese listeners in the United States, and native Chinese listeners in China. Results showed that in general, EN listeners outperformed the two groups of CN listeners in quiet and noise, while CNU listeners had better scores of sentence recognition than CNC listeners. Moreover, the native English exposure helped CNU listeners use high-level linguistic cues more effectively and take more advantage of temporal fluctuations of noise to process English sentence in severely degraded listening conditions [i.e., the signal-to-noise ratio of −12 dB] than CNC listeners. These results suggest a significant effect of language experience on the auditory processing of both speech and noise. (shrink)

There is a long‐standing project in psychology the goal of which is to explain our ability to perceive speech. The project is motivated by evidence that seems to indicate that the cognitive processing to which speech sounds are subjected is somehow different from the normal processing employed in hearing. The Motor Theory of speech perception was proposed in the 1960s as an attempt to explain this specialness. The first part of this essay is concerned with the (...) Motor Theory's explanandum. It shows that it is rather hard to give a precise account of what the Motor Theory is a theory of. The second part of the essay identifies problems with the theory's explanans: There are difficulties in finding a plausible account of what the content of the Motor Theory is supposed to be.

[Frank Ebersole is a philosopher] "whose contribution to philosophy... is the greatest of anyone this [the 20th] century, especially in the areas of philosophy of language, theory of knowledge, and perception." from Wittgenstein, Empiricism, and Language by John W. Cook (Oxford University Press, 1999). Language and Perception has nine chapters: seven that address philosophical problems about language and two (chapters 2 and 9) that are more metaphilosophical The metaphilosophical chapters discuss philosophical pictures and some (...) of Frank Ebersole's basic ideas about philosophy. The other seven essays let you participate in his unique struggles to come to terms with such questions as: What is the meaning of a word? Isn't Wittgenstein's idea that things called by the same name have family resemblances significantly flawed? Does language determine what we perceive? Does a thing's being red cause it to look red (the causal theory of perception)? Must the action of speaking be analyzed into simpler actions such as making sounds? Can a bodily movement be part of an action? Is fatalism implied by "what one might say" about the future? Are "natural-kind" words like proper names? are they rigid designators? This and its companion volume, Meaning and Saying, are not just other philosophy books about the philosophy of language. In both books Ebersole, by carefully using examples, convincingly shows that the problems are the products of philosophical pictures. The examples also make the pictures less compelling. How the Second Edition Differs from the First Edition This edition differs from the first edition (University Press of America, 1979) in several ways. Pictures: Material that was formerly part of a postscript to chapter 1 has been revised and is now its own chapter, chapter 2, "Pictures and Wittgenstein on Pictures." As a result the following chapters were renumbered. Essay removed: Chapter 7 in the first edition, "Truth and Fate: Future Actions," has been removed. Essay added: A new essay, entitled "Proper Names and Other Names," has been added to the volume. It's a revised version of an essay originally published in Philosophical Investigations, Oct., 1982, with the title "Stalking the Rigid Designator." Postscript: Material that was formerly part of the preface is now revised and placed as chapter 9 at the end, entitled "Postscript." Improved text: Throughout the book, Ebersole has made corrections, stylistic improvements, and changed the wording to remove ambiguities. Preface The book is concerned with questions about the "relations of language to reality": Does physical reality predetermine the form of our language? Does it determine the kinds of words in our simple, basic vocabulary? Does our language in basic ways determine the way we perceive reality? Does our language embody the outlines of a certain theory of perception? And does it incorporate a certain view of human actions and of the future? These questions are expressions of the problems in the philosophy of language that people inevitably get themselves into while dealing with other philosophical problems. And these are problems in the philosophy of language that have direct consequences for the way one deals with problems in other branches of philosophy. At. (shrink)

It can be a great challenge for second language learners to comprehend meanings that are implied in utterances rather than the surface meaning of what was said. Moreover, L2 learners’ attitudes toward pragmatic learning are unknown. This mixed-methods study investigates L2 learners’ ability to comprehend conversational implicatures. It also explores their beliefs about and intentions to develop this ability using Ajzen’s theory of planned behavior. A total of 498 freshmen from a public university in China participated in the (...) study. Data were collected using a web-based test, stimulated recall tasks and semi-structured interviews. Results show that the participants differed in recognizing the intended meanings. Complicated factors account for the variations. In addition to the types of implicature, learners’ beliefs about developing pragmatic comprehension also influence their learning intention, and subsequent performance. These beliefs include learners’ multi-layered, complex attitudes toward the outcomes of pragmatic learning, perceived self-efficacy beliefs regarding language proficiency and L2 cultural knowledge, actual behavioral control over opportunities and resources for pragmatic learning, and perceptions of less social pressure on pragmatic learning. The use of TPB may help language teachers and test designers to understand learners’ beliefs about L2 pragmatic learning in the English as a foreign language context. Understanding the factors influencing learners’ intention will help design more effective teaching curricula that may integrate pragmatic instruction and testing in the future. (shrink)

Language experience shapes the gradual maturation of speech production in both native and second languages. Structural aspects like the connectedness of spontaneous narratives reveal this maturation progress in L1 acquisition and, as it does not rely on semantics, it could also reveal structural pattern changes during L2 acquisition. The current study tested whether L2 lexical retrieval associated with vocabulary knowledge could impact the global connectedness of narratives during the initial stages of L2 acquisition. Specifically, the study evaluated (...) the relationship between graph structure and L2 learners’ oral production in the L2 and L1. Seventy-nine college-aged students who were native speakers of English and had received classroom instruction in either L2-Spanish or L2-Chinese participated in this study. Three tasks were used: semantic fluency, phonemic fluency and picture description. Measures were operationalized as the number of words per minute in the case of the semantic and phonemic fluency tasks. Graph analysis was carried out for the picture description task using the computational tool SpeechGraphs to calculate connectedness. Results revealed significant positive correlations between connectedness in the picture description task and measures of speech production in the phonemic and semantic fluency tasks. These correlations were only significant for the participants’ L2- Spanish and Chinese. Results indicate that producing low connectedness narratives in L2 may be a marker of the initial stages of L2 oral development. These findings are consistent with the pattern reported in the early stages of L1 literacy. Future studies should further explore the interactions between graph structure and second language production proficiency, including more advanced stages of L2 learning and considering the role of cognitive abilities in this process.

In terms of classical tafsir literature, it is possible that the speeches made to a person or group in the Qurʾān carry messages for other individuals or groups. According to some approaches that emerged in the modern period, when the speech was made and to whom it was directed not only determine the meaning, but also limits it. This dilemma has to be based on the theoretical dimension. The most obvious example of the transition of the speech from (...) direct counterpart to the other is the transition of the speeches made to the unbelievers to the believers. Therefore, in this study, the possibility of the transcendence of the speech in the Qurʾān will be handled in the context of the messages for believers in the speeches directed to the unbelievers. One aspect of the issue of the transcendence of the speech in the Qurʾān can be explained by the style that the Qurʾān follows. However, the subject should also be based on linguistic aspects. As a matter of fact, the expansion of the speech can sometimes be related to the meanings of words and sometimes with the possibilities and literary aspects of language, and sometimes with an analytical effort. In this study, the related examples will be analyzed and it will be revealed that the transition between the speeches in the Qurʾān is possible in terms of the style of the Qurʾān. In the study, the methodological findings related to the linguistic aspects of the issue will also be studied.Summary: The discourse that the Qurʾān is an address by God makes different associations in terms of classical literature and some modern methods of understanding. In the works of classical method and rhetoric, a theoretical framework is drawn around the nature, arbitrariness, conditions and types of the book. In this context, the varieties, indications and scopes of the addresses in the Qurʾān are discussed. While it is emphasized that the Qurʾān is an address in modernist contextualist approaches, it is stated that understanding the address requires having contextual information, therefore reading the address as a book evaporates meaning. Because, according to these approaches, the meaning is sought in the text with the transformation of address to book (verbal culture to written culture), thus the Qurʾān is converted from a literal meaning into a system. Knowing what the Qurʾān tells and why it tells that, depends on the comprehension of all the contextual elements of the Qurʾān, which was sent as an address. In fact, knowledge of when, where and when the Qurʾān was sent about what events and to whom it is addressed, is the data that is primarily considered in the comprehension of the verses, as emphasized by the classical interpretation literature. However, the perception of the classical interpretation evaluates these data in different categories in terms of the integrity of religion, judgment and experience. For example, the narrations on the reason of sending and the Makki-Madani information are only examples of the meanings of the verses. They sometimes serve as elements that contribute to the comprehension of the verses, while sometimes with the help of other chapters they can narrow the meanings of the verses. The realist-methodological basis of the method science provides the emergence of this holistic-categorical perspective.It is difficult to justify the claim that there is an absolute relationship between the address and the addressee in terms of the classical literature. In the classical literature, the expressions, which come in the form of an address and have a mandatory relationship with addressees, are dealt with the concept of direct address. Direct addresses are binding for the first addressees. Because when an address is mentioned, it is mandatory to have an addressee. It can be assumed that this discourse has the same position with the context theories considering its premises. However, it is not possible to compare these theories with each other in terms of the scope of the address. Classical theories of reasoning consider that direct addresses cover indirect addressees by methods, such as shar’i (legal) necessity or analogy (qiyas), while contextualists and historians can convert the text beyond the virtual level by identifying what a command means within the context of the address-addressee relationship. When the Qurʾān is completely considered as an address, or when direct addresses are taken into consideration, it is very difficult for the modern period's comprehension methods that the verses, which mention or address the disbelievers-polytheists, can also address Muslims. In fact, the dialectic of the address-addressee requires this. Moreover, the addressees (polytheists-Muslims) who are spoken within the context of the verses have two different beliefs that cannot be dealt with at the same time and mentioned in the same verse. Therefore, it is not possible to direct the messages given to the polytheists to the believers and to attribute the qualities in these verses to Muslims.However, the classical literature did not even consider as a problem to address Muslims with the verses that directly addressing unbelievers-polytheists. It is because both linguistics and facts requires this. The method practitioners and interpreters discussed this issue in a very wide range. They examined the transitivity of the book between parties, such as people of the book-Muslims, Muslims-unbelievers, Prophet-ummah. In the context of the interpretation literature and the perception of modern-day interpretation, the possibility of the transitivity of the book can be clarified in the context of the inclusiveness of a verse that speaks of polytheists-disbelievers to include Muslims, or the conversion of an address to polytheists-unbelievers to Muslims. Classical literature explains this point sometimes with the literal indication (circularization) and the circumstance of literary use of language (rhetoric) and sometimes with the possibility of the address (stylistic features).In verses and hadiths, belief bases categorical classes, such as believers, unbelievers, polytheists, hypocrites, people of the book are mentioned, as well as descriptions of the characteristic-practical dimensions of these classes. In this context, commands sometimes refer to the practices that need to be performed in order to be a believer, sometimes works that must not be performed by the believer, and sometimes matters that might put the believer's faith-practice integrity at risk when it is done. In the Qurʾān, in some of the addresses to the believers, it is apparent that they are prohibited from being like unbelievers or having unbeliever-like qualities. Moreover, sometimes negative results that may arise for Muslims when they act like unbelievers are cited in the verses. Sometimes at the end of the verses that address and mention Muslims, information is included on situations involving unbelievers and the torment they will encounter. In addition, in cases where adjectives belonging to opposing belief profiles are mentioned, the address to non-Muslims expresses warning, evaluation, gratitude and perseverance in faith for Muslims, while the address to Muslims contains elements of incentive and opportunity for non-Muslim groups. It is possible to justify this matter with the style of the Qurʾān. However, it can be said that the transitivity of the address in the Qurʾān takes place in two theoretical aspects. The first of these is related to linguistic-rhetoric premises and it is used in antithesis, allusion, metaphor etc. The second one is the similitude-comparison. Here, the comparison is a phenomenon that occurs in the mind without the need for propositions. Because when the mind hears these statements, it can instantly reach a stronger meaning than the literal wording. In this study, it is discussed whether it is possible to transition from direct addresses to indirect addressees, with reference to the problems of the modern period. In this context, the study primarily focuses on the fact that the Qurʾān sometimes transmits its messages and teachings to addressees through opposing belief systems. Thus, the manner adopted by the Qurʾān while directing certain commands and negations, not directly but through the opposing side, has been presented. In this study, the possibility of the verses that only mentions polytheists-unbelievers to also addressing Muslims was analyzed and these verses were compared with addresses to Muslims on the same matters. In the last part of the study, a theoretical framework was drawn on the subject and the method of interdisciplinary transitivity was determined. (shrink)

Saffran, Newport, and Aslin (1996a) found that human infants are sensitive to statistical regularities corresponding to lexical units when hearing an artificial spoken language. Two sorts of segmentation strategies have been proposed to account for this early word‐segmentation ability: bracketing strategies, in which infants are assumed to insert boundaries into continuous speech, and clustering strategies, in which infants are assumed to group certain speech sequences together into units (Swingley, 2005). In the present study, we test the predictions (...) of two computational models instantiating each of these strategies i.e., Serial Recurrent Networks: Elman, 1990; and Parser: Perruchet & Vinter, 1998 in an experiment where we compare the lexical and sublexical recognition performance of adults after hearing 2 or 10 min of an artificial spoken language. The results are consistent with Parser’s predictions and the clustering approach, showing that performance on words is better than performance on part‐words only after 10 min. This result suggests that word segmentation abilities are not merely due to stronger associations between sublexical units but to the emergence of stronger lexical representations during the development of speech perception processes.

Several studies have demonstrated that individuals’ ability to perceive a speech sound contrast is related to the production of that contrast in their native language. The theoretical account for this relationship is that speech perception and production have a shared multimodal representation in relevant sensory spaces. This gives rise to a prediction that individuals with more narrowly defined targets will produce greater separation between contrasting sounds, as well as lower variability in the production of each sound. (...) However, empirical studies that tested this hypothesis, particularly with regard to variability, have reported mixed outcomes. The current study investigates the relationship between perceptual ability and production ability, focusing on the auditory domain. We examined whether individuals’ categorical labeling consistency for the American English /ε/–/æ/ contrast, measured using a perceptual identification task, is related to distance between the centroids of vowel categories in acoustic space and to two measures of production variability: the overall distribution of repeated tokens for the vowels and the proportional within-trial decrease in variability as defined as the magnitude of self-correction to the initial acoustic variation of each token. No significant associations were found between categorical labeling consistency and vowel contrast distance, between categorical labeling consistency and area of the ellipse, or between categorical labeling consistency and centering ratio. These null results suggest that the perception-production relation may not be as robust as suggested by a widely adopted theoretical framing in terms of the size of auditory target regions. However, the present results may also be attributable to choices in implementation that should be subject to further investigation. (shrink)

We recently reported strong, replicable (i.e., replicated) evidence for lexically mediated compensation for coarticulation (LCfC; Luthra et al., 2021), whereby lexical knowledge influences a prelexical process. Critically, evidence for LCfC provides robust support for interactive models of cognition that include top‐down feedback and is inconsistent with autonomous models that allow only feedforward processing. McQueen, Jesse, and Mitterer (2023) offer five counter‐arguments against our interpretation; we respond to each of those arguments here and conclude that top‐down feedback provides the most parsimonious (...) explanation of extant data.

Multiple acoustic dimensions signal speech categories. However, dimensions vary in their informativeness; some are more diagnostic of category membership than others. Speech categorization reflects these dimensional regularities such that diagnostic dimensions carry more “perceptual weight” and more effectively signal category membership to native listeners. Yet perceptual weights are malleable. When short-term experience deviates from long-term language norms, such as in a foreign accent, the perceptual weight of acoustic dimensions in signaling speech category membership rapidly adjusts. The (...) present study investigated whether rapid adjustments in listeners’ perceptual weights in response to speech that deviates from the norms also affects listeners’ own speech productions. In a word recognition task, the correlation between two acoustic dimensions signaling consonant categories, fundamental frequency and voice onset time, matched the correlation typical of English, and then shifted to an “artificial accent” that reversed the relationship, and then shifted back. Brief, incidental exposure to the artificial accent caused participants to down-weight perceptual reliance on F0, consistent with previous research. Throughout the task, participants were intermittently prompted with pictures to produce these same words. In the block in which listeners heard the artificial accent with a reversed F0 × VOT correlation, F0 was a less robust cue to voicing in listeners’ own speech productions. The statistical regularities of short-term speech input affect both speech perception and production, as evidenced via shifts in how acoustic dimensions are weighted. (shrink)

The overall aim of this article is to discuss how the MUSIC Model of Motivation can be applied to L2 instruction in a manner that is consistent with positive psychology, which emphasizes individuals’ strengths and the conditions in which they thrive. The article begins by describing the MUSIC model, which is a research-based framework that organizes strategies that instructors can use to motivate students to engage in learning. The MUSIC model can be used by L2 instructors to create learning experiences (...) that consider learners’ cognition, affect, needs, and desires in order to foster their motivation and engagement in L2 classes. The article also provides teaching strategies related to the MUSIC model and presents an assessment tool (the MUSIC Model of Academic Motivation Inventory) that can be used by L2 instructors to measure students’ MUSIC perceptions of their class. The assessment tool provides feedback to instructors that can be used to improve their instruction by incorporating strategies that allow their students to flourish. Examples of how the MUSIC Inventory can be used to assess L2 instruction are provided. Although researchers have examined the use of the MUSIC model in L2 classes, this research is underdeveloped, and many questions related to its use in L2 classes remain. The article concludes by proposing unanswered questions that could lead to more effective uses of the MUSIC model in L2 classes. (shrink)

During natural speech perception, listeners rely on a wide range of cues to support comprehension, from semantic context to prosodic information. There is a general consensus that prosody plays a role in syntactic parsing, but most studies focusing on ambiguous relative clauses (RC) show that prosodic cues, alone, are insufficient to reverse the preferred interpretation of sentence. These findings suggest that universally preferred structures (e.g., Late Closure principle) matter far more than prosodic cues in such cases. This study (...) explores an alternative hypothesis: that the weak effect of prosody might be due to the influence of various syntactic, lexical-semantic, and acoustic confounding factors, and investigate the consequences of prosodic breaks while controlling these variables. We used Spanish RC sentences in three experimental conditions where the presence and position (following the first or second noun phrase) of prosodic breaks was manipulated. The results showed that the placement of a prosodic break determined sentence interpretation by changing the preferred attachment of the RC. Listeners’ natural preference for low attachment (in the absence of break) was reinforced when a prosodic break was placed after the first noun. In contrast, a prosodic break placed after the second noun reversed the preferred interpretation of the sentence, toward high attachment. We argue that, in addition to other factors, listeners indeed use prosodic breaks as robust cues to syntactic parsing during speech processing, as these cues may direct listeners toward one interpretation or another.

Using fMRI, we investigated how right temporal lobe gliomas affecting the posterior superior temporal sulcus alter neural processing observed during speech perception and production tasks. Behavioural language testing showed that three pre-operative neurosurgical patients with grade 2, grade 3 or grade 4 tumours had the same pattern of mild language impairment in the domains of object naming and written word comprehension. When matching heard words for semantic relatedness (a speech perception task), these patients showed (...) under-activation in the tumour infiltrated right superior temporal lobe compared to 61 neurotypical participants and 16 patients with tumours that preserved the right postero-superior temporal lobe, with enhanced activation within the (tumour-free) contralateral left superior temporal lobe. In contrast, when correctly naming objects (a speech production task), the patients with right postero-superior temporal lobe tumours showed higher activation than both control groups in the same right postero-superior temporal lobe region that was under-activated during auditory semantic matching. The task dependent pattern of under-activation during the auditory speech task and over-activation during object naming was also observed in eight stroke patients with right hemisphere infarcts that affected the right postero-superior temporal lobe compared to eight stroke patients with right hemisphere infarcts that spared it. These task-specific and site-specific cross-pathology effects highlight the importance of the right temporal lobe for language processing and motivate further study of how right temporal lobe tumours affect language performance and neural reorganisation. These findings may have important implications for surgical management of these patients, as knowledge of the regions showing functional reorganisation may help to avoid their inadvertent damage during neurosurgery.

This paper advances a novel argument that speech perception is a complex system best understood nonindividualistically and therefore that individualism fails as a general philosophical program for understanding cognition. The argument proceeds in four steps. First, I describe a "replaceability strategy", commonly deployed by individualists, in which one imagines replacing an object with an appropriate surrogate. This strategy conveys the appearance that relata can be substituted without changing the laws that hold within the domain. Second, I advance (...) a "counterfactual test" as an alternative to the replaceability strategy. Third, I show how the typical objects of cross-modal processes (in this case, auditory-visual speech perception), more clearly irreplaceable than the objects of the unimodal process examined by Burge [(1986) Individualism and psychology, The Philosophical Review, XCV, 3-45], supply a firm basis for a nonindividualist interpretation of such cases. Finally, I demonstrate that the routine violation of the individualist's Replaceability Condition occurs even in unimodal cases - so the violation of the replaceability constraint does not derive simply from the diversity of modal sources but rather from the causal complexity of psychological processes generally. The conclusion is that philosophical progress on this issue must await progress in psychology, or, at least, philosophical progress in accounting for psychological complexity--precisely the vicissitude predicted by a thoroughgoing naturalism.

When you hear a person speaking in a familiar language you perceive the speech sounds uttered and the voice that produces them. How are speech sounds and voice related in a typical auditory experience of hearing speech in a particular voice? And how to conceive of the objects of such experiences? I propose a conception of auditory objects of speech perception as temporally structured mereologically complex individuals. A common experience is that speech sounds (...) and the voice that produces them appear united. I argue that the metaphysical underpinnings of the experienced unity of speech sounds and voices can be explained in terms of the mereological view on sounds and their sources. I also propose a psychological explanation of how we form and individuate the auditory objects of experiences of listening to speech in a particular voice. Voice characteristics enable determining the identity of auditory objects of speech sound perception by making some features of the speech signal stable and predictable. (shrink)
