The sounds that make up spoken words are heard in a series and must be mapped rapidly onto words in memory because their elements, unlike those of visual words, cannot simultaneously exist or persist in time. Although theories agree that the dynamics of spoken word recognition are important, they differ in how they treat the nature of the competitor set—precisely which words are activated as an auditory word form unfolds in real time. This study used eye tracking to measure the (...) impact over time of word frequency and 2 partially overlapping competitor set definitions: onset density and neighborhood density. Time course measures revealed early and continuous effects of frequency (facilitatory) and on set based similarity (inhibitory). Neighborhood density appears to have early facilitatory effects and late inhibitory effects. The late inhibitory effects are due to differences in the temporal distribution of similarity within neighborhoods. The early facilitatory effects are due to subphonemic cues that inform the listener about word length before the entire word is heard. The results support a new conception of lexical competition neighborhoods in which recognition occurs against a background of activated competitors that changes over time based on fine-grained goodness-of-fit and competition dynamics.

Despite the lack of invariance problem (the many‐to‐many mapping between acoustics and percepts), human listeners experience phonetic constancy and typically perceive what a speaker intends. Most models of human speech recognition (HSR) have side‐stepped this problem, working with abstract, idealized inputs and deferring the challenge of working with real speech. In contrast, carefully engineered deep learning networks allow robust, real‐world automatic speech recognition (ASR). However, the complexities of deep learning architectures and training regimens make it difficult to use them to (...) provide direct insights into mechanisms that may support HSR. In this brief article, we report preliminary results from a two‐layer network that borrows one element from ASR, long short‐term memory nodes, which provide dynamic memory for a range of temporal spans. This allows the model to learn to map real speech from multiple talkers to semantic targets with high accuracy, with human‐like timecourse of lexical access and phonological competition. Internal representations emerge that resemble phonetically organized responses in human superior temporal gyrus, suggesting that the model develops a distributed phonological code despite no explicit training on phonetic or phonemic targets. The ability to work with real speech is a major advance for cognitive models of HSR. (shrink)

The question of when and how bottom‐up input is integrated with top‐down knowledge has been debated extensively within cognition and perception, and particularly within language processing. A long running debate about the architecture of the spoken‐word recognition system has centered on the locus of lexical effects on phonemic processing: does lexical knowledge influence phoneme perception through feedback, or post‐perceptually in a purely feedforward system? Elman and McClelland (1988) reported that lexically restored ambiguous phonemes influenced the perception of the following phoneme, (...) supporting models with feedback from lexical to phonemic representations. Subsequently, several authors have argued that these results can be fully accounted for by diphone transitional probabilities in a feedforward system (Cairns et al., 1995; Pitt & McQueen, 1998). We report results strongly favoring the original lexical feedback explanation: lexical effects were present even when transitional probability biases were opposite to those of lexical biases. (shrink)

Norris et al.'s claim that feedback is unnecessary is compromised by (1) a questionable application of Occam's razor, given strong evidence for feedback in perception; (2) an idealization of the speech recognition problem that simplifies those aspects of the input that create conditions where feedback is useful; (3) Norris et al.'s use of decision nodes that incorporate feedback to model some important empirical results; and (4) problematic linking hypotheses between crucial simulations and behavioral data.

Distributional semantic models (DSMs) are a primary method for distilling semantic information from corpora. However, a key question remains: What types of semantic relations among words do DSMs detect? Prior work typically has addressed this question using limited human data that are restricted to semantic similarity and/or general semantic relatedness. We tested eight DSMs that are popular in current cognitive and psycholinguistic research (positive pointwise mutual information; global vectors; and three variations each of Skip-gram and continuous bag of words (CBOW) (...) using word, context, and mean embeddings) on a theoretically motivated, rich set of semantic relations involving words from multiple syntactic classes and spanning the abstract–concrete continuum (19 sets of ratings). We found that, overall, the DSMs are best at capturing overall semantic similarity and also can capture verb–noun thematic role relations and noun–noun event-based relations that play important roles in sentence comprehension. Interestingly, Skip-gram and CBOW performed the best in terms of capturing similarity, whereas GloVe dominated the thematic role and event-based relations. We discuss the theoretical and practical implications of our results, make recommendations for users of these models, and demonstrate significant differences in model performance on event-based relations.

A long-standing question in cognitive science is how high-level knowledge is integrated with sensory input. For example, listeners can leverage lexical knowledge to interpret an ambiguous speech sound, but do such effects reflect direct top-down influences on perception or merely postperceptual biases? A critical test case in the domain of spoken word recognition is lexically mediated compensation for coarticulation (LCfC). Previous LCfC studies have shown that a lexically restored context phoneme (e.g., /s/ in Christma#) can alter the perceived place of (...) articulation of a subsequent target phoneme (e.g., the initial phoneme of a stimulus from a tapes-capes continuum), consistent with the influence of an unambiguous context phoneme in the same position. Because this phoneme-to-phoneme compensation for coarticulation is considered sublexical, scientists agree that evidence for LCfC would constitute strong support for top–down interaction. However, results from previous LCfC studies have been inconsistent, and positive effects have often been small. Here, we conducted extensive piloting of stimuli prior to testing for LCfC. Specifically, we ensured that context items elicited robust phoneme restoration (e.g., that the final phoneme of Christma# was reliably identified as /s/) and that unambiguous context-final segments (e.g., a clear /s/ at the end of Christmas) drove reliable compensation for coarticulation for a subsequent target phoneme. We observed robust LCfC in a well-powered, preregistered experiment with these pretested items (N = 40) as well as in a direct replication study (N = 40). These results provide strong evidence in favor of computational models of spoken word recognition that include top–down feedback. (shrink)

The effects of lexical context on phonological processing are pervasive and there have been indications that such effects may be modulated by attention. However, attentional modulation in speech processing is neither well documented nor well understood. Experiment 1 demonstrated attentional modulation of lexical facilitation of speech sound recognition when task and critical stimuli were identical across attention conditions. We propose modulation of lexical activation as a neurophysiologically plausible computational mechanism that can account for this type of modulation. Contrary to the (...) claims of critics, this mechanism can account for attentional modulation without violating the principle of interactive processing. Simulations of the interactive TRACE model extended to include two different ways of modulating lexical activation showed that each can account for attentional modulation of lexical feedback effects. Experiment 2 tested conflicting predictions from the two implementations and provided evidence that is consistent with bias input as the mechanism of attentional control of lexical activation.

Bilinguals have been shown to perform worse than monolinguals in a variety of verbal tasks. This study investigated this bilingual verbal cost in a large-scale picture-naming study conducted in Spanish. We explored how individual characteristics of the participants and the linguistic properties of the words being spoken influence this performance cost. In particular, we focused on the contributions of lexical frequency and phonological similarity across translations. The naming performance of Spanish-Catalan bilinguals speaking in their dominant and non-dominant language was compared (...) to that of Spanish monolinguals. Single trial naming latencies were analyzed by means of linear mixed models accounting for individual effects at the participant and item level. While decreasing lexical frequency was shown to increase naming latencies in all groups, this variable by itself did not account for the bilingual cost. In turn, our results showed that the bilingual cost disappeared when naming words with high phonological similarity across translations. In short, our results show that frequency of use can play a role in the emergence of the bilingual cost, but that phonological similarity across translations should be regarded as one of the most important variables that determine the bilingual cost in speech production. Low phonological similarity across translations yields worse performance in bilinguals and promotes the bilingual cost in naming performance. The implications of our results for the effect of phonological similarity across translations within the bilingual speech production system are discussed. (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.

Visual word recognition is facilitated by the presence of orthographic neighbors that mismatch the target word by a single letter substitution. However, researchers typically do not consider where neighbors mismatch the target. In light of evidence that some letter positions are more informative than others, we investigate whether the influence of orthographic neighbors differs across letter positions. To do so, we quantify the number of enemies at each letter position (how many neighbors mismatch the target word at that position). Analyses (...) of reaction time data from a visual word naming task indicate that the influence of enemies differs across letter positions, with the negative impacts of enemies being most pronounced at letter positions where readers have low prior uncertainty about which letters they will encounter (i.e., positions with low entropy). To understand the computational mechanisms that give rise to such positional entropy effects, we introduce a new computational model, VOISeR (Visual Orthographic Input Serial Reader), which receives orthographic inputs in parallel and produces an over‐time sequence of phonemes as output. VOISeR produces a similar pattern of results as in the human data, suggesting that positional entropy effects may emerge even when letters are not sampled serially. Finally, we demonstrate that these effects also emerge in human subjects' data from a lexical decision task, illustrating the generalizability of positional entropy effects across visual word recognition paradigms. Taken together, such work suggests that research into orthographic neighbor effects in visual word recognition should also consider differences between letter positions. (shrink)

That art historians have felt it necessary to emulate this effort to express personal input can be explained by our need to gain credibility in that aspect of our work that is indistinguishable in method from other historical research: the reconstruction, through documents and artifacts, of past events, conditions, and attitudes. Most of us simply ignore the ambivalence of our position; I cannot recall having heard or read discussions of it, but it is bound to creep out from under the (...) rug. If a student asks me why I think Rembrandt and Picasso are good artists—which most students are too well trained to do—and if I answer that judgments of value are not discussed by historians, I am within my rights, like a witness at a congressional hearing claiming the protection of the Fifth Amendment. But I ought to be found in contempt of the classroom. And if I try to answer seriously, I ought not begin by saying that I chose Rembrandt because he has been acknowledged by generations to have been a great artist but rather because I find more to think, feel, and speak about in his works than in those of, for example, Nicolaes Maes, and because I believe that the student stands to gain more by looking at them. I want the student to have the most rewarding experiences, and, as a result, perhaps to learn to make value discriminations of his own—even ones different from mine and from the so-called consensus of history—and ultimately to explain the grounds on which he makes them. This means having to know and to explain what I think is "rewarding." James S.

It may seem reasonable, even inevitable, that architectural practice should be based on an understanding that architects, like lawyers and doctors, should discover their clients' needs and accommodate them to the best of their abilities. But current discussion within the legal and medical professions of the conflict between service to private individuals who can pay, and to the public who cannot, suggest an expanded or altered definition of professional responsibility. Actually, the conflict between public and private interest may be more (...) acute in architecture than in other professions: the kind of buildings architects design are costly and are made possible only by the wealth of a small segment of the population or the state, yet every one raised affects the lives of people other than the one who makes the program and pays the architect for his services. Furthermore, the decisions of architects are embodied in buildings that last for generations, even for millennia, so that the overwhelming majority of people in our culture live and work in places designed not only for other people but for other times and conditions. For this reason, even the "private" practice of architecture involves responsibilities to a widespread constituency. James S.

In this widely acclaimed work, James Ackerman considers in detail the buildings designed by Michelangelo in Florence and Rome--including the Medici Chapel, the Farnese Palace, the Basilica of St. Peter, and the Capitoline Hill. He then turns to an examination of the artist's architectural drawings, theory, and practice. As Ackerman points out, Michelangelo worked on many projects started or completed by other architects. Consequently this study provides insights into the achievements of the whole profession during the sixteenth century. The (...) text is supplemented with 140 black-and-white illustrations and is followed by a scholarly catalog of Michelangelo's buildings that discusses chronology, authorship, and condition. For this second edition, Ackerman has made extensive revisions in the catalog to encompass new material that has been published on the subject since 1970. (shrink)

This article reflects on one potential relationship the anthropological study of religion might enjoy with a critical orientation to religion. To do so, I highlight a burgeoning dialog between anthropology and theology. Ultimately, I propose that a focus on religion and human flourishing provides one wavelength on which an anthropology–theology collaboration can thrive. I follow the observation that anthropologists and theologians are united by concern with shared problems. If human and social flourishing is one such problem, then what might a (...) collaborative configuration look like? The example I consider is how ethnographic evidence of religion in public life can be mobilized to advance prophetic theological critiques of injustice. (shrink)

We only see Mars from Earth's perspective in the first season of The Expanse, but Season 2 changes that by introducing Gunnery Sergeant Bobbie Draper, a Martian Congressional Republic Navy (MCRN) marine. Mars as seen by Martians resembles our Mars: ruddy, rocky, dusty, inhospitable, and cold. This chapter focuses on Draper and the Mars Congressional Republic (MCR). What is striking about the culture of the MCR is how naturally it flows from contemporary visions of space exploration, especially those from the (...) Apollo era forward. For somewhat more specific examples, the chapter considers the “Statement of Philosophy” of the National Space Society, another well‐known space advocacy organization in the US. The MCR's commitment to terraforming Mars demonstrates that its future depends “upon the progress of science and technology.”. (shrink)

This article explores four major areas of moral concern regarding virtual reality technologies. First, VR poses potential mental health risks, including Depersonalization/Derealization Disorder. Second, VR technology raises serious concerns related to personal neglect of users’ own actual bodies and real physical environments. Third, VR technologies may be used to record personal data which could be deployed in ways that threaten personal privacy and present a danger related to manipulation of users’ beliefs, emotions, and behaviors. Finally, there are other moral and (...) social risks associated with the way VR blurs the distinction between the real and illusory. These concerns regarding VR naturally raise questions about public policy. The article makes several recommendations for legal regulations of VR that together address each of the above concerns. It is argued that these regulations would not seriously threaten personal liberty but rather would protect and enhance the autonomy of VR consumers. (shrink)

This book aims to contribute significantly to the understanding of issues of value which repeatedly emerge in interdisciplinary discussions on space and society. Although a recurring feature of discussions about space in the humanities, the treatment of value questions has tended to be patchy, of uneven quality and even, on occasion, idiosyncratic rather than drawing upon a close familiarity with state-of-the-art ethical theory. One of the volume's aims is to promote a more robust and theoretically informed approach to the ethical (...) dimension of discussions on space and society. While the contributions are written in a manner which is accessible across disciplines, the book still withstands scrutiny by those whose work is primarily on ethics. At the same time it allows academics across a range of disciplines an insight into current approaches toward how the work of ethics gets done. The issues of value raised could be used to inform debates about regulation, space law and protocols for microbial discovery as well as longer-range policy debates about funding. (shrink)

According to Stewart Shapiro's coherence principle, structures exist whenever they can be coherently described. I argue that Shapiro's attempts to justify this principle are circular, as he relies on criticisms of modal nominalism which presuppose the coherence principle. I argue further that when the coherence principle is not presupposed, his reasoning more strongly supports modal nominalism than ante rem structuralism.
