This question arises in debates over the representation of linguistic dependencies: whether they are mediated by unpronounced elements (empty categories; ECs) or established without them. Some psycholinguistic research has taken dependency-distance effects—the observation that longer dependencies impose greater processing cost—as evidence in favor of EC-free over EC-mediated accounts, and this claim has recently been revived. In this letter, I argue that this conclusion is unwarranted. Once the incremental, real-time nature of sentence processing is taken into account, dependency-distance effects are expected under EC-mediated accounts as well. I show how EC-mediated accounts can explain these effects and review findings consistent with this view. Dependency-distance effects are, therefore, not diagnostic of whether dependencies involve ECs.

Construing a belief in probabilistic terms (other than 0% or 100%) implicitly conveys a recognition of uncertainty (one's ignorance) and the possibility of being wrong (one's fallibility), which are key characteristics of intellectual humility (IH).

This study investigates the vertical mappings of Cantonese lexical tones (high rising vs. low falling) in two crossmodal domains: (1) spatial motions (upward vs. downward) and (2) emotional valence (positive vs. negative). Results showed that Cantonese speakers could reliably map tones based on pitch and motion trajectories (i.e., rising contour is upward, and falling contour is downward), but the vertical mapping between tones and valence (i.e., rising contour is positive, and falling contour is negative) was much weaker and modulated by vowels. In general, these findings suggest that lexical tones can be conceptualized and understood in the vertical dimension, even in the language where speakers do not talk about tones using spatially relevant terms. In addition, tonal iconicity, and sound symbolism in general, is differentiated according to the mechanisms in which they are grounded. Specifically, sound symbolism that relies on a direct structural parallel produces a more consistent mapping, whereas correspondence grounded in metaphorical mediation is more easily influenced by other linguistic factors. Thus, this research provides evidence for the sound symbolic nature of lexical tones, suggesting their conceptual mapping in tonal languages.</p>","PeriodicalId":48349,"journal":{"name":"Cognitive Science","volume":"50 8","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148680547","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}

However, a definitive answer is still lacking as to whether the low-level visual cortex plays its role at the feedforward stage of processing. To resolve this issue, we measured event-related potentials (ERPs) evoked by two equal-size circles flashed on the left and right sides of human participants, with one side constantly displaying large surrounding inducers and the other side small inducers. Experiment 1 unveiled a significant lateralization in the evoked C1 component, a well-established ERP index of afferent V1 activity, only when the circle within small inducers was perceived as larger but not when the circle within large inducers was perceived as larger. This illusion-specific C1 lateralization, which closely resembled the C1 modulation evoked by physical differences in size, was further replicated in Experiment 2 even when the attentional bias toward small inducers was invalidated as an alternative account. Furthermore, Granger causality analysis revealed a one-way transfer of information from V1-representative electrodes to extrastriate-representative electrodes during the C1 lateralization. Together, these findings offer the strongest evidence to date that the Ebbinghaus illusion begins at the feedforward stage of cortical visual processing, consistent with the prediction of the contour interaction theory.</p>","PeriodicalId":48349,"journal":{"name":"Cognitive Science","volume":"50 8","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148664806","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}

In continuous real-world environments, however, social judgments naturally vary, making judgment similarity a potentially important cue for consensus. The present study investigated whether similarity among others’ judgments modulates conformity. Across two perceptual estimation experiments, participants first estimated the location of a briefly presented target and then revised their estimates after viewing two partners’ responses. In Experiment 1, in which partner responses were attributed to humans, participants showed greater conformity when partners’ estimates were highly similar. Computational modeling formalized this process within a Bayesian belief-updating framework, suggesting that judgment similarity increased the evidential weight assigned to social information. In Experiment 2, this similarity-dependent effect was attenuated when the same response structure was explicitly attributed to computer programs rather than human agents. These findings indicate that conformity in continuous judgment spaces cannot be fully explained by a domain-general statistical heuristic or passive imitation alone. Instead, individuals appear to evaluate both the content of social evidence and the attributed properties of its source, using judgment similarity as a cue for integrating information from others.</p>","PeriodicalId":48349,"journal":{"name":"Cognitive Science","volume":"50 8","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148617087","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}

An alternative position suggests chunking in language and cognition involves multiple mechanisms tuned to the specific perceptual properties and statistical regularities of the target structures of learning. To test these hypotheses, we compared performance on two different forms of chunking in English: (1) multiword chunking as assessed by a recall task involving multiple high- and low-frequency three-word sequences, and (2) clausal chunking in which participants intuitively insert chunk boundaries on a touchscreen tablet while listening to speech extracts and viewing the corresponding transcripts. Results indicated no correlations between multiword chunking and clausal chunking, providing initial support for the notion that chunking processes may likely not operate equally across or even within the same cognitive domain, casting doubt on a unitary view of chunking.

Yet, division of labor benefits collaboration not only by assigning people to tasks that match their competences, but by allowing them to improve “on-the-job” through training and practice. Thus, optimal division of labor requires anticipating how each individual will develop and what roles they will eventually be best suited for. Existing research on collaboration, however, rarely considers this prospective dimension. To address this gap, we studied how humans make training decisions, while manipulating the long-term consequences of those decisions. Across three experiments (<span></span><math>\u0000 <semantics>\u0000 <mrow>\u0000 <mi>N</mi>\u0000 <mo>=</mo>\u0000 </mrow>\u0000 <annotation>$N =$</annotation>\u0000 </semantics></math> 600), participants trained two military defense teams to counter two types of attacks (land and air), where the long-term goals and the teams' relative competences varied. Participants made a sequence of training decisions before assigning teams to roles in the final battle. Overall, participants divided labor and trained collaborators by considering how each team's competence would develop, and whether they would eventually meet task demands. These patterns were best captured by a Planning model that trained collaborators based on the expected outcome at the time of deployment. The Planning model outperformed several heuristic alternatives that optimized training based on current competence, learning potential, fairness, or versatility. Together, these findings provide a first step toward understanding how training unlocks one of the central benefits of dividing labor—complementary competences.
