Recently, a puzzling finding has emerged: Once children master the FB task, they begin to fail true belief (TB) control tasks. This finding threatens the validity of FB tasks and the standard view. Here, we test two prominent attempts to explain the puzzling findings against each other. The perceptual access reasoning account (a competence limitation account) assumes that children at age 4 do not yet engage in meta-representation, but use simpler heuristics (“if an agent has perceptual access, she knows and then acts successfully; otherwise, she acts unsuccessfully”). In contrast, the pragmatics approach (a performance limitation account) suggests that children at age 4 do have meta-representational ToM but are confused by pragmatic task factors of the TB task. The current study tested competing predictions of both accounts in a decision experiment. Results from 165 4- to 7-year-olds reveal that failure in the TB task disappeared once the tasks were modified: children mastered both FB and TB tasks when the latter were adapted in terms of heuristic and pragmatic factors. Importantly, this pattern held in conditions in which the pragmatics account predicts success, but the perceptual access account predicts failure. Overall, the present findings thus corroborate the standard view (children use meta-representational ToM from age 4, at the latest) and suggest that difficulties with TB tasks merely reflect pragmatic performance factors.</p>","PeriodicalId":48349,"journal":{"name":"Cognitive Science","volume":"49 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cogs.70069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine at what stage the CW bias emerges, we tested this preference across multiple visual awareness paradigms using consistent 2D rotation stimuli. In Experiment 1, we found a strong CW bias in apparent motion, with CW dominating perception 1.6 times longer than CCW during long-term presentations and eliciting an average of 74% CW percepts in short-term presentations. By contrast, no CW bias was observed in binocular rivalry, suggesting its absence in low-level perceptual conflict. Experiment 2 employed the breaking continuous flash suppression (b-CFS) paradigm to assess unconscious preferences, revealing no difference in breakthrough times between CW and CCW rotations. Specifically, although apparent motion stimuli showed a higher frequency of CW percepts, breakthrough times for stimuli reported as CW and CCW were similar, indicating that the CW bias occurs after stimuli reach awareness. In Experiment 3, we manipulated the ambiguity of apparent motion stimuli and found significant interactions between the CW bias and input ambiguity, further ruling out a fixed sensory or response bias. These findings suggest that the CW bias in 2D rotation may be driven by higher-level cognitive processes, offering insights into how the visual system resolves perceptual ambiguity.</p>","PeriodicalId":48349,"journal":{"name":"Cognitive Science","volume":"49 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This raises the possibility that rules are slow to emerge because they are not needed in order to represent smaller numbers (e.g., up to 20). Here, we investigated this possibility in adult learners by training them on a series of artificial number “languages” that manipulated the availability of rules, by varying the numerical base in each language.

Our results showed that, in a learning environment where the true category mapping was determined by conjunctions of two predictive dimensions, the likelihood of falling into a single-dimensional learning trap increased when early learning experience involved a large loss that could be predicted from a single feature dimension. In addition, using a model-based measurement of attention bias, we observed that early experience affected trap formation by narrowing the distribution of attention to exemplar features.

What are the fundamental dynamical principles behind the movements that structure speech production? In this study, we discover models in the form of symbolic equations that govern articulatory gestures during speech. A sparse symbolic regression algorithm is used to discover models from kinematic data on the tongue and lips. We explore these candidate models using analytical techniques and numerical simulations and find that a second-order linear model achieves high levels of accuracy, but a nonlinear force is required to properly model articulatory dynamics in approximately one third of cases. This supports the proposal that an autonomous, nonlinear, second-order differential equation is a viable dynamical law for articulatory gestures in speech.

One process of alignment is lexical entrainment, whereby partners mirror and abbreviate their word usage to converge on shared terms for referents relevant to the conversation. However, lexical entrainment may result in inefficient mimicry that does not add new information, suggesting that task-oriented communication may favor alignment through other means. The present study investigates the process of alignment in Danish conversations in which dyads learned to categorize unfamiliar “aliens” using trial-and-error feedback. Performance improved as dyad communication became less verbose, measured as a decrease in the entropy of word usage. Word usage also diverged between partners as measured by Jensen−Shannon Divergence, which indicates that alignment was not achieved through lexical entrainment. A computational model of dyadic communication is shown to account for the alien game results in terms of joint least effort. The model shows that alignment of partner referents can increase as a result of minimizing both the joint entropy of dyadic word usage and the conditional entropy of individual referents given the joint signal distribution. We conclude that the principle of least effort, originally proposed to shape language evolution, may also support alignment in task-oriented communication.</p>","PeriodicalId":48349,"journal":{"name":"Cognitive Science","volume":"49 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose that it can be more parsimoniously explained as an outcome of word-class frequencies, where the purported “head” is the most frequently instantiated word class in a phrasal schema. We show that the most frequent class gravitates spontaneously to an edge position in a phrasal replication process, as long as words of one class may influence the position of words of another class. This avoids the need to posit head-dependent ordering as an innate rule or bias, simplifying our theory of word order. We demonstrate the spontaneous emergence of harmony from word-class frequencies using a simple computational model of phrasal replication, and in further extensions show that the principle remains robust with fuzzy word classes and multiword chunks, can capture competition between harmony and locality, and is compatible with the results of behavioral experiments on harmonic ordering.

This commentary explores the theoretical impossibility of maintaining uninterrupted attention, drawing from extensive interdisciplinary research in cognitive science, neuroscience, and psychology. Multiple converging lines of evidence demonstrate that sustained attention is constrained by neural, biological, and cognitive limitations. Neural mechanisms reveal that attention operates through rhythmic oscillations, with inherent fluctuations in frontoparietal networks and default mode network interactions. Neurochemical systems and cellular adaptation effects further underscore the impossibility of continuous, perfect vigilance. Empirical research across domains—including aviation, healthcare, industrial safety, and security—consistently demonstrates rapid declines in attention performance over time, regardless of individual expertise or motivation. Even elite performers like military personnel and experienced meditators exhibit inevitable attention lapses. This paper presents an argument against traditional approaches that seek to overcome these limitations through training or willpower. Instead, it advocates for designing human–technology systems that work harmoniously with cognitive constraints. This requires developing adaptive automation, understanding individual and cultural attention variations, and creating frameworks that strategically balance human capabilities with technological support.</p>","PeriodicalId":48349,"journal":{"name":"Cognitive Science","volume":"49 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cogs.70061","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, in spoken languages, word forms can be “played with” in iconic gradient ways by varying vowel length, pitch, or speed (e.g., “It's been a loooooooong day”). However, little is known about this process in sign languages. Here, we (1) explore gradient modification in three dimensions of motion in American Sign Language (ASL), and (2) ask whether the three dimensions are equally likely to be modified. We asked deaf signers of ASL (<i>n</i> = 11, mean age = 49.3) to describe an event manipulated along speed, direction, or path, and observed their use of gradient modification in lexical and depicting signs. We found that signers alter the forms of both types of signs to enhance meaning. However, the three motion dimensions were not modified equally in lexical signs, suggesting constraints on gradient modification. These constraints may be linguistic in nature, found only in signers. Alternatively, the constraints could reflect difficulties in using the hands to convey particular modifications and, if so, should be found in speakers as well as signers.</p>","PeriodicalId":48349,"journal":{"name":"Cognitive Science","volume":"49 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cogs.70051","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, we adopt a cognitive perspective on genericity. Specifically, we draw on learning principles that predict asymmetries in the acquisition of category representations, which in turn might determine the acceptance of generic sentences. Our key hypotheses were that generics are more likely accepted when the attributes they refer to are distinctive (i.e., more prevalent in the category relative to comparison categories) and that this pattern is sensitive to the temporal order in which category information is acquired. We report three preregistered experiments to test these hypotheses. In all experiments, we employed a trait-learning paradigm in which participants received information about exemplars of two fictitious kinds (human-like sea creatures in Experiments 1–3, stones in Experiment 2) in sequential order. We manipulated the prevalence of attributes within kinds, as well as their status as being shared between kinds or distinctive for either the first- or second-learned kind. As hypothesized, generic sentences were more likely accepted when referring to distinctive (vs. shared) attributes, but only for the second-learned kind.
