Abstract Knowledge of someone’s friendships can powerfully impact how one interacts with them. Previous research suggests that information about others’ real-world social network positions—e.g. well-connected they are (centrality), ‘degrees separation’ (relative distance)—is spontaneously encoded when encountering familiar individuals. However, many types covary where someone sits in a network. For instance, strangers’ face-based trait impressions associated their centrality, and distance centrality inherently intertwined familiarity, interpersonal similarity memories. To disentangle the encoding position from other information, participants learned novel which was decoupled factors then saw each person’s image during functional magnetic resonance imaging scanning. Using representational analysis, we found robustly regions visual attention mentalizing. Thus, even considering is not included unlinked perceptual experience-based features to it inextricably tied naturalistic contexts, brain encodes importance network, likely shaping future perceptions interactions those

Autism spectrum disorder (ASD) is characterized by difficulties in social processes, interactions, and communication. Yet, the neurocognitive bases underlying these are unclear. Here, we triangulated 'trans-diagnostic' approach to personality, trait judgments of faces, neurophysiology investigate (1) relative position autistic traits a comprehensive social-affective personality space, (2) distinct associations between dimensions judgment from faces individuals with ASD neurotypical individuals. We collected facial data large sample online participants (N = 89 self-identified ASD; N 307 controls). Factor analysis 33 subscales 10 questionnaires identified 4-dimensional space. This revealed that control did not differ significantly along empathy prosociality, antisociality, or agreeableness. However, exhibited weaker association prosocial trustworthiness warmth than participants. Neurophysiological also indicated had neuronal representations for faces. These results suggest atypical may contribute affective associated ASD.

Healthy social life requires relationships in different levels of personal closeness. Based on ethological, sociological, and psychological evidence, networks have been divided into five layers, gradually increasing size decreasing Is this division also reflected brain processing networks? During functional MRI, 21 participants compared their closeness to individuals. We examined the volume showing differential activation for varying layers found that a disproportionately large portion (80%) exhibited preference individuals closest participants, while separate regions showed all other layers. Moreover, bipartition cortical sizes physical spaces, as well distinct subsystems default mode network. Our results support neurocognitive two patterns depending closeness, reflecting unique role intimately close play our lives. Most effort is dedicated small group very This study reveals these people differs from broader network, paralleling versus distant places.

Previous research has established that the brain uses episodic memories to make continuous predictions about world and prediction errors, so mismatch between generated reality, can lead memory updating. However, it remains unclear whether errors stimulate updating in for naturalistic conversations. Participants encoded dialogues, which were later presented a modified form. We found larger modifications associated with increased learning of statement. Moreover, original version statement was weakened after medium-strong resulted from interplay modification extent strength previous memory. After strong both well-remembered.

Abstract There is disagreement regarding the major components of brain network supporting spatial cognition. To address this issue, we applied a lesion mapping approach to clinical phenomenon topographical disorientation. Topographical disorientation inability maintain accurate knowledge about physical environment and use it for navigation. A review published cases identified 65 different sites. Our analysis yielded map encompassing classic regions navigation network: medial parietal, temporal, temporo-parietal cortices. We also ventromedial region prefrontal cortex, which has been absent from prior descriptions network. Moreover, revealed that mapped are correlated with Default Mode Network sub-network C. Taken together, study provides causal evidence distribution cognitive system, demarking identifying novel regions.

People form impressions about others during daily social encounters and infer personality traits from others’ behaviors. Such trait inference is thought to rely on two universal dimensions, i.e., competence warmth. These dimensions can be used construct a ‘social cognitive map’ organizing massive information obtained efficiently. Originated spatial cognition, the neural codes supporting representation navigation of map has been widely studied. Recent studies suggest similar mechanism subserves map-like architecture in cognition as well. Here we investigated how operate beyond physical environment support map. We designed value space defined by Behaviorally, participants were able navigate learned location random starting locations this abstract space. At level, identified distance precuneus, fusiform gyrus middle occipital gyrus. also found grid-like patterns medial prefrontal cortex entorhinal cortex.

Abstract A cognitive map is an internal representation of the external world that guides flexible behavior in a complex environment. Cognitive theory assumes relationships between entities can be organized using Euclidean‐based coordinates.

The first learned rank objects each dimension then completed transitive task.

Our memories of episodic experiences are represented and organized by contexts. Events that share overlapping contextual features such as spatio-temporal proximity more likely to be together in our memories. But how do we represent remember other people? The predominant view social cognition is people a bundle attributes personality traits. However, real-world contexts most often learn about others observing or participating interactions, which inform understanding interpersonal-relationships. In this study, explore spontaneously after watching character-driven television show. We find memory for individual characters around interpersonal relationships rather than person- situation-specific (i.e., actions, traits, groups, locations). Moreover, even the subtle order participants recalled names each character can predicted graphs character’s network. These findings suggest way naturally largely driven their connections with others. believe work provides new avenues inquiry move beyond person-centric approaches novel perspective on research.
