In this issue of Cognition, Thompson and her colleagues challenge the results from a paper we published several years ago. That paper demonstrated that metacognitive difficulty or disfluency can trigger more analytical thinking as measured by accuracy on several reasoning tasks. In their experiments, Thompson et al. find evidence that people process information more deeply—but not necessarily more accurately—when they experience disfluency. These results are consistent with our original theorizing, but the authors misinterpret it as counter-evidence because they suggest that (...) accuracy is a measure of deeper processing rather than a contingent outcome of such processing. We further suggest that Thompson et al. err when they discriminate between “perceptual fluency” and “answer fluency,” the former of which is an element of the latter. Thompson et al. advance research by adding reaction time as a measure of deeper cognitive processing, but we caution against misinterpreting the meaning of accuracy. (shrink)

Après avoir fait l’état des lieux de la base de données VALIBEL en la situant dans son contexte institutionnel, nous mettons en exergue dans cet article quelques possibilités d’investigation qu’offre la base en regard de ses évolutions récentes. Une attention particulière est portée à l’outillage des corpus en termes de disfluences (avec le programme DisMo) et à l’étude du vieillissement langagier (liée au corpus Corpage). Nous concluons en montrant en quoi l’enrichissement constant de la base (en outillage et en corpus) (...) permet d’ouvrir de nouvelles pistes de recherches dans des domaines encore peu explorés en linguistique, eu égard à des problématiques sociétales majeures.

Four studies explore the role of perceptual fluency in attenuating bullshit receptivity, or the tendency for individuals to rate otherwise meaningless statements as “profound”. Across four studies, we presented participants with a sample of pseudoprofound bullshit statements in either a fluent or disfluent font and found that overall, disfluency attenuated bullshit receptivity while also finding little evidence that this effect was moderated by cognitive thinking style. In all studies, we measured participants’ cognitive reflection, need for cognition, faith in intuition, and (...) superstitious beliefs. Superstition strongly predicted bullshit receptivity regardless of fluency. Inconclusive results were found for the remaining scales. Potential links for the role of perceptual disfluency in promoting analytic thinking are discussed. (shrink)

Disfluencies include editing terms such as uh and um as well as repeats and revisions. Little is known about how disfluencies are processed, and there has been next to no research focused on the way that disfluencies affect structure-building operations during comprehension. We review major findings from both computational linguistics and psycholinguistics, and then we summarize the results of our own work which centers on how the parser behaves when it encounters a disfluency. We describe some new (...) research showing that information associated with misarticulated verbs lingers, and which adds to the large body of data on the critical influence of verb argument structures on sentence comprehension. The paper also presents a model of disfluency processing. The parser uses a Tree Adjoining Grammar to build phrase structure. In this approach, filled and unfilled pauses affect the timing of Substitution operations. Repairs and corrections are handled by a mechanism we term “Overlay,” which allows the parser to overwrite an undesired tree with the appropriate, correct tree. This model of disfluency processing highlights the need for the parser to sometimes coordinate the mechanisms that perform garden-path reanalysis with those that do disfluency repair. The research program as a whole demonstrates that it is possible to study disfluencies systematically and to learn how the parser handles filler material and mistakes. It also showcases the power of Tree Adjoining Grammars, a formalism developed by Aravind Joshi which has yielded results in many different areas of linguistics and cognitive science. (shrink)

Over the last few decades, empirical researchers have become increasingly interested in explaining the formation of “basic” aesthetic judgments, i.e. simple judgments of sensory preferability and the pleasure that seems to accompany them. To that end, Reber et al. have recently defended a “processing-fluency” view, which identifies aesthetic pleasure with one’s ability to easily process an object’s perceptual properties (e.g. Reber 2012 ). While the processing-fluency theory is certainly an improvement over its competitors, it is currently vulnerable to several serious (...) criticisms. In what follows, I aim to provide a more holistic, explanatorily robust, model of the processing-fluency theory of aesthetic pleasure by incorporating what the view neglects: the crucial role of perceptual disfluency, interest, and the underlying values that drive aesthetic appraisal.

A speaker's manner of delivery of an utterance can affect a listener's pragmatic interpretation of the message. Disfluencies influence a listener's off-line assessment of whether the speaker is truthful or deceptive. Do listeners also form this assessment during the moment-by-moment processing of the linguistic message? Here we present two experiments that examined listeners’ judgments of whether a speaker was indicating the true location of the prize in a game during fluent and disfluent utterances. Participants’ eye and mouse movements were (...) biased toward the location named by the speaker during fluent utterances, whereas the opposite bias was observed during disfluent utterances. This difference emerged rapidly after the onset of the critical noun. Participants were similarly sensitive to disfluencies at the start of the utterance and in the middle. Our findings support recent research showing that listeners integrate pragmatic information alongside semantic content during the earliest moments of language processing. Unlike prior work which has focused on pragmatic effects in the interpretation of the literal message, here we highlight disfluency's role in guiding a listener to an alternative non-literal message.

Speech disfluencies can signal that a speaker is about to refer to something difficult to name. In two experiments, we found evidence that 4-year-olds, like adults, flexibly interpret a particular partner’s disfluency based on their estimate of that partner’s knowledge, derived from the preceding conversation. In entrainment trials, children established partner-specific shared knowledge of names for tangram pictures with one or two adult interlocutors. In each test trial, an adult named one of two visible tangrams either fluently or disfluently (...) while children’s eye-movements were monitored. We manipulated speaker knowledge in the test trials. In Experiment 1, the test-trial speaker was the same speaker from entrainment or a naïve experimenter; in Experiment 2, the test-trial speaker had been one of the child’s partners in entrainment and had seen half of the tangrams. When hearing disfluent expressions, children looked more at a tangram that was unfamiliar from the speaker’s perspective; this systematic disfluency effect disappeared in Experiment 1 when the speaker was entirely naïve, and depended on each speaker’s entrainment experience in Experiment 2. These findings show that 4-year-olds can keep track of two different partners’ knowledge states, and use this information to determine what should be difficult for a particular partner to name, doing so efficiently enough to guide online interpretation of disfluent speech.

The English language now dominates scientific communications. Yet, many scientists have English as their second language. Their English proficiency may therefore often be more limited than that of a ‘native speaker’, and their scientific contributions (e.g. manuscripts) in English may frequently contain linguistic features that disrupt the fluency of a reader’s, or listener’s information processing even when the contributions are understandable. Scientific gatekeepers (e.g. journal reviewers) sometimes cite these features to justify negative decisions on manuscripts. Such justifications may rest on (...) the prima facie plausible assumption that linguistic characteristics that hinder fast and easy understandability of scientific contributions are epistemically undesirable in science. I shall raise some doubts about this assumption by drawing on empirical research on processing fluency and its biasing effects. I also argue that directing scientists with English as a foreign language toward approaching ‘native-level’ English can have the negative consequence of reducing their potential to make scientific belief formation more reliable. These points suggest that one seemingly compelling justification for linguistically discriminating against scientific contributions in ‘non-native’ English is questionable and that the common insistence by scientific gatekeepers on ‘native-like’ English may be epistemically harmful to science.

This commentary identifies two problems concerning the switch mechanism: The model explains too few instances of switching, and the switching mechanism itself seems fallible. The improvements we suggest are to clarify the nature of the competing intuitions as the initial intuition and its negation or alternative ways to solve the problem, and to incorporate cognitive disfluency into the switching mechanism.

Culture-as-situated cognition theory provides insight into the system 1 monitoring algorithm. Culture provides people with an organizing framework, facilitating predictions, focusing attention, and providing experiential signals of certainty and uncertainty as system 1 inputs. When culture-based signals convey that something is amiss, system 2 reasoning is triggered and engaged when resources allow; otherwise, system 1 reasoning dominates.

Although widely studied in other domains, relatively little is known about the metacognitive processes that monitor and control behaviour during reasoning and decision-making. In this paper, we examined the conditions under which two fluency cues are used to monitor initial reasoning: answer fluency, or the speed with which the initial, intuitive answer is produced, and perceptual fluency, or the ease with which problems can be read. The first two experiments demonstrated that answer fluency reliably predicted Feeling of Rightness judgments to (...) conditional inferences and base rate problems, which subsequently predicted the amount of deliberate processing as measured by thinking time and answer changes; answer fluency also predicted retrospective confidence judgments. Moreover, the effect of answer fluency on reasoning was independent from the effect of perceptual fluency, establishing that these are empirically independent constructs. In five experiments with a variety of reasoning problems similar to those of Alter et al., we found no effect of perceptual fluency on FOR, retrospective confidence or accuracy; however, we did observe that participants spent more time thinking about hard to read stimuli, although this additional time did not result in answer changes. In our final two experiments, we found that perceptual disfluency increased accuracy on the CRT, but only amongst participants of high cognitive ability. As Alter et al.’s samples were gathered from prestigious universities, collectively, the data to this point suggest that perceptual fluency prompts additional processing in general, but this processing may results in higher accuracy only for the most cognitively able.

Miscommunication phenomena such as repair in dialogue are important indicators of the quality of communication. Automatic detection is therefore a key step toward tools that can characterize communication quality and thus help in applications from call center management to mental health monitoring. However, most existing computational linguistic approaches to these phenomena are unsuitable for general use in this way, and particularly for analyzing human–human dialogue: Although models of other-repair are common in human-computer dialogue systems, they tend to focus on specific (...) phenomena, missing the range of repair and repair initiation forms used by humans; and while self-repair models for speech recognition and understanding are advanced, they tend to focus on removal of “disfluent” material important for full understanding of the discourse contribution, and/or rely on domain-specific knowledge. We explain the requirements for more satisfactory models, including incrementality of processing and robustness to sparsity. We then describe models for self- and other-repair detection that meet these requirements and investigate how they perform on datasets from a range of dialogue genres and domains, with promising results.

Understanding the changes in our language abilities along the lifespan is a crucial step for understanding the aging process both in normal and in abnormal circumstances. Besides controlled experimental tasks, it is equally crucial to investigate language in unconstrained conversation. I present an information-theoretical analysis of a corpus of dyadic conversations investigating how the richness of the vocabulary, the word-internal structure, and the syntax of the utterances evolves as a function of the speaker's age and sex. Although vocabulary diversity increases (...) throughout the lifetime, grammatical diversities follow a different pattern, which also differs between women and men. Women use increasingly diverse syntactic structures at least up to their late fifties, and they do not deteriorate in terms of fluency through their lifespan. However, from age 45 onward, men exhibit a decrease in the diversity of the syntactic structures they use, coupled with an increased number of speech disfluencies. (shrink)

ABSTRACTFacial features that resemble emotional expressions influence key social evaluations, including trust. Here, we present four experiments testing how the impact of such expressive features is qualified by their processing difficulty. We show that faces with mixed expressive features are relatively devalued, and faces with pure expressive features are relatively valued. This is especially true when participants first engage in a categorisation task that makes processing of mixed expressions difficult and pure expressions easy. Critically, we also demonstrate that the impact (...) of categorisation fluency depends on the specific nature of the expressive features. When faces vary on valence, trust judgments increase with their positivity, but also depend on fluency. When faces vary on social motivation, trust judgments increase with their approachability, but remain impervious to disfluency. This suggests that people intelligently use fluency to make judgments on val... (shrink)

Communicating with multiple addressees poses a problem for speakers: Each addressee necessarily comes to the conversation with a different perspective—different knowledge, different beliefs, and a distinct physical context. Despite the ubiquity of multiparty conversation in everyday life, little is known about the processes by which speakers design language in multiparty conversation. While prior evidence demonstrates that speakers design utterances to accommodate addressee knowledge in multiparty conversation, it is unknown if and how speakers encode and combine different types of perspective information. (...) Here we test whether speakers encode the perspective of multiple addressees, and then simultaneously consider their knowledge and physical context during referential design in a three‐party conversation. Analyses of referential form—expression length, disfluency, and elaboration rate—in an interactive multiparty conversation demonstrate that speakers do take into consideration both addressee knowledge and physical context when designing utterances, consistent with a knowledge‐scene integration view. These findings point to an audience design process that takes as input multiple types of representations about the perspectives of multiple addressees, and that bases the informational content of the to‐be‐designed utterance on a combination of the perspectives of the intended addressees.

In this reply, we provide an analysis of Alter et al. response to our earlier paper. In that paper, we reported difficulty in replicating Alter, Oppenheimer, Epley, and Eyre’s main finding, namely that a sense of disfluency produced by making stimuli difficult to perceive, increased accuracy on a variety of reasoning tasks. Alter, Oppenheimer, and Epley argue that we misunderstood the meaning of accuracy on these tasks, a claim that we reject. We argue and provide evidence that the tasks were (...) not too difficult for our populations and point out that in many cases performance on our tasks was well above chance or on a par with Alter et al.’s participants. Finally, we reiterate our claim that the distinction between answer fluency and perceptual fluency is genuine, and argue that Thompson et al. provided evidence that these are distinct factors that have different downstream effects on cognitive processes.

Syntactic complexity effects have been investigated extensively with respect to comprehension . According to one prominent class of accounts , certain structures cause comprehension difficulty due to their scarcity in the language. But why are some structures less frequent than others? In two elicited-production experiments we investigated syntactic complexity effects in relative clauses and wh-questions varying in whether or not they contained non-local dependencies. In both experiments, we found reliable durational differences between subject-extracted structures and object-extracted structures : Participants took (...) longer to begin and produce object-extractions. Furthermore, participants were more likely to be disfluent in the object-extracted constructions. These results suggest that there is a cost associated with planning and uttering the more syntactically complex, object-extracted structures, and that this cost manifests in the form of longer durations and disfluencies. Although the precise nature of this cost remains to be determined, these effects provide one plausible explanation for the relative rarity of object-extractions: They are more costly to produce.

The question of conjoined artistic- and phenomenological research practice is explored through two realizations of a drawing-based practice, complemented with a language-based practice that includes transcriptions of a spoken monologue while and about drawing. Through adapting the sense that the monologue’s addressee is an apparently other person, and narrating this situation, the author expresses through the article that the experiential process of drawing is automatically phenomenological. In turn, the article is a presentation of how phenomenological reflection is implicit in the (...) practice. The artist- referenced in the article is termed the artist-author, declared as such to the reader, and is thereafter suggested as split into an apparently more reflexively inclined artist and a more reflectively inclined author/interlocutor. The hypothesis that both artistic- and phenomenological research can manifest as a single practice is embedded in the article’s manner of presentation, the reader of which is almost in the same interlocutory position as the author-, of the artist-author, in being able to notice this. The article’s actual author, however, refers to himself as a homunculus, in effect the hyphen of artist-author, that enables him to detach sufficiently from what can be read and seen to format the article in such terms as enable the reader to critically reflect on its hypothesis. The role of the camera itself, considered as a metaphor for interaction between the reflexive event and its subsequent language-based reflection, is also acknowledged, especially in the context of the artist-’s referencing in the drawing and in his speech how the camera both aids and obfuscates the process, and linking this to theory. The transcript conveys spoken enunciation, especially through its grammatically formatted disfluency and extended pauses, and the author’s personal declaration and observation of himself – reminding the reader that the article’s content is after all about its narrator – is italicized.

This article investigates the new phenomenon of e-mailed questions to a radio phone-in programme, BBC Radio 4's `Election Call'. Our interest in this phenomenon arose for several reasons. First, as a new form, e-mails were singled out at the beginning of each broadcast for special instructions to listeners, although there was evidence that as the series progressed, dealing with e-mail became more of a routine event in each subsequent programme. Second, on listening to the Election Call broadcasts, the sequential introduction (...) of an e-mail question appeared to be problematic for the host. First mentions of e-mailed questions were often subject to a noticeable amount of disfluency and repair work, in contrast to the well-rehearsed and highly routine introduction of callers' questions. Third, we are interested in the function of e-mail questions in terms of how they are handled by the host and guest. Are they given the same status as a `call', and if not, where do the differences lie? In our analysis we show how the introduction of this new media form into a well-established context opens up new structural possibilities for both host as interviewer and politician as interviewee, in terms of how questions get framed, and how they get responded to.

Mathematics word problems provide students with an opportunity to apply what they are learning in their mathematics classes to the world around them. However, students often neglect their knowledge of the world and provide nonsensical responses (e.g., they may answer that a school needs 12.5 buses for a field trip). This study examined if the question design of word problems affects students' mindset in ways that affect subsequent sense‐making. The hypothesis was that rewriting standard word problems to introduce inherent uncertainty (...) about the result would be beneficial to student performance and sense‐making because it requires students to reason explicitly about the context described in the problem. Middle school students (N = 229) were randomly assigned to one of three conditions. In the standard textbook condition, students solved a set of six word problems taken from current textbooks. In the modified yes/no condition, students solved the same six problems rewritten so the solution helped answer a “yes” or “no” question. In the disfluency control condition, students solved the standard problems each rewritten in a variety of fonts to make them look unusual. After solving the six problems in their assigned condition, all students solved the same three “problematic” problems designed to assess sense‐making. Contrary to predictions, results showed that students in the modified yes/no condition solved the fewest problems correctly in their assigned condition problem set. However, consistent with predictions, they subsequently demonstrated more sense‐making on the three problematic problems. Results suggest that standard textbook word problems may be able to be rewritten in ways that mitigate a “senseless” mindset. (shrink)

When examining the history of early imperial China one is struck by the number of important personages, from Han Feizi 韓非子 and Yang Xiong 揚雄 to Guo Pu 郭璞 and Wang Wei 王微, who are described in biographical records as kouji 口吃. This paper contextualizes these descriptions by examining both the hermeneutical tradition regarding the language used to describe this condition and its evolving understanding in the traditional Chinese medical records. These two broad bodies of social understanding provide a compelling (...) tool for interpreting and contextualizing the many descriptions of individuals in the early imperial biographical tradition. It becomes clear when taken in this larger context and as a collective that this condition is not just a random oddity to be included in a biography as merely an outlying feature of an individual, but that disfluency was understood in the much more highly charged realm of language production and moral practice. It spoke to the long-standing tension over rhetorical skill versus moral intent, form versus content. Finally, what also emerges from the collective is a clearer understanding of the range of strategies that individuals with this disability found to navigate the specific social context of early imperial elite culture. It is out of these dual views, collective-moral and individual-functional, that this study provides insights into the lives of these highly influential individuals and adds layers to our understanding of the social and medical context for individuals with disabilities in early imperial China.

In our article, “Syntactic complexity effects in sentence production”, we reported two elicited production experiments and argued that there is a cost associated with planning and uttering syntactically complex, object-extracted structures that contain a non-local syntactic dependency. MacDonald et al. () have argued that the results of our investigation provide little new information on the topic. We disagree. Examining the production of subject versus object extractions in two constructions across two experimental paradigms—relative clauses in Experiment 1 and wh-questions in Experiment (...) 2—we found a strikingly similar pattern: reliable differences in latency and word durations, as well as in rates of disfluencies, signaling a greater cost associated with planning and uttering the syntactically more complex object extractions. MacDonald et al. reject that interpretation, namely that the differences we observed in the production of subject versus object extractions demonstrate asymmetric production difficulties. Here we address the concerns they raise by clarifying confusion and presenting novel experimental evidence in support of our original claims. (shrink)

ABSTRACT The paper discusses the main principles in designing and annotating speech corpora within the framework of the Saint Petersburg phonological school, and provides examples of using corpus data in phonetic research. One of the major principles that we follow is to analyse the speech material at all levels: from segmental to intonational, including speech disfluencies. During segmental phonetic annotation, we suggest listening to each speech sound in isolation (without knowing its context) and relying on spectrographic data. At the (...) syllabic tier, it is crucial to reflect resyllabification. During prosodic annotation, we suggest to rely on listener’s perception of the intonation pattern first, then analyse the actual melodic curves. A speech corpus with multi-level annotation that follows these principles is a valuable source of phonetic data — as segmental and prosodic factors are in constant interaction with each other, and one cannot analyse units of one annotation tier without reference to other tiers.

ABSTRACT The BiRCh Project (The Corpus of Bilingual Russian Child Speech) involves collecting a longitudinal audio corpus of Russian spoken by children and their families in Russia, Ukraine, Germany, the U.S., and Canada. We are building a large-scale corpus based on a subset of this data, the “Parsed and Audio-aligned Corpus of Bilingual Russian Child and Child-directed Speech (BiRCh)” with two basic components: (1) 1-million-word transcripts which are time-aligned with the audio speech signal and fully textsearchable, and (2) a 500K-word (...) morphologically annotated and parsed portion of the transcripts, also audio-aligned. We are using this corpus to investigate various phenomena in the linguistic input and the developmental trajectory of heritage bilinguals, e.g., case, gender, passives, impersonals, politeness markers, disfluencies, and discourse markers. This article focuses on the challenges and solutions of the BiRCh development and the implications for research on the richly annotated data provided by the corpus. (shrink)

While there is a considerable body of research on law student identity construction based on interviews and transcripts of classroom talk, there is very little work based on student written texts. In this article two letters of advice written by beginning law students are analysed, using Ivanic and Camps’s framework, as an example of identity formation. Legal identity is argued to be formed by students’ attempts to accommodate a dynamic, partial, practitioner role of provider of advice to the traditional analytic (...) focus of the law student. The process of accommodation is evident in the language of the letters, which show disfluencies resulting from attempts to combine different roles into a coherent legal identity. Comparison with a professionally written letter suggests that, rather than seeking to shape a coherent position, lawyers are able simultaneously to hold incompatible perspectives, concealing the tensions by foregrounding some perspectives and backgrounding others.

Intuitively, the accuracy of initial word-referent mappings should be positively correlated with the outcome of learning. Yet recent evidence suggests an inverse effect of initial accuracy in adults, whereby greater accuracy of initial mappings is associated with poorer outcomes in a cross-situational learning task. Here, we examine the impact of initial accuracy on 4-year-olds, 10-year-olds, and adults. For half of the participants most word-referent mappings were initially correct and for the other half most mappings were initially incorrect. Initial accuracy was (...) positively related to learning outcomes in 4-year-olds, had no effect on 10-year-olds' learning, and was inversely related to learning outcomes in adults. Examination of item learning patterns revealed item interdependence for adults and 4-year-olds but not 10-year-olds. These findings point to a qualitative change in language learning processes over development. (shrink)
