This study investigates the dynamic neural organization of social cognition in children (<em>n</em> = 60, ages 3–10) and adults (<em>n</em> = 55) using a naturalistic fMRI paradigm that tracks continuous brain activity during real-world social interactions. We identify four distinct co-activation patterns (CAP) that reflect a functional hierarchy, ranging from basic sensory processing to complex social-cognitive integration. These brain state dynamics reveal significant developmental differences: children exhibit immature transitions, often bypassing intermediate states (e.g., salience-driven filtering, State 3) and prematurely shifting from early sensory encoding (State 1) to internally-directed integration (State 2). Moreover, during mentalizing and pain events, children show reduced modulation of sensory and perceptual brain states, indicating limited cognitive flexibility that is essential for social interaction. Structural equation modeling reveals a developmental cascade linking the maturation of sensory (State 1), perceptual filtering (State 3), and social-cognitive (State 2) processing states. This pathway is mediated by individual differences in Theory of Mind (ToM) development and further predicts empathic abilities. These findings advance our understanding of how brain state reorganization supports social cognitive maturation and offer new insights into neurodevelopmental disorders.</div></div>","PeriodicalId":49083,"journal":{"name":"Developmental Cognitive Neuroscience","volume":"78 ","pages":"Article 101670"},"PeriodicalIF":4.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145929006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Age-related strengthening of beta responses in the IFG was also correlated with lesser attentional symptomology.

To address these questions, we used functional MRI to collect precision functional mapping (PFM) data in eight individual neonates (mean 42.7 weeks postmenstrual age) over 2–5 days (mean 77.9 min of low motion data per subject [framewise displacement &lt;0.1]).

Across subject similarity of whole-brain FC was r = 0.62 on average and significantly lower than within-subject similarity (t = 5.9, p &lt; 0.001). Using established methods to identify transitions in FC across the cortical surface, we identified sets of cortical areas for each individual that were subject-specific and highly reliable across split-halves (mean z = 4.4, SD=1.4).

Using a population-based birth cohort, we observed a small but significant decrease in the unpredictability of maternal sensory signals over time. This suggests that caregiving predictability may increase as children develop. Nonetheless, within-individual unpredictability showed some stability across time. Importantly, lower unpredictability of maternal sensory signals was associated with membership in more favorable EF profiles, characterized by stronger working memory performance at age five. In contrast, children exposed to more unpredictable maternal sensory signals demonstrated poorer early EF development. These findings build on and extend prior work by modeling unpredictability of maternal sensory signals longitudinally beyond toddlerhood and linking it to children's EF development, highlighting the prolonged sensitivity of EFs to caregiving behavior. Our results underscore that unpredictability in caregiving behavior is a unique and critical factor in shaping early cognitive development and self-regulation.

This study used electroencephalography (EEG) to examine the neural responses related to top-down attention (frontal theta synchronization), action processing (mu desynchronization), and approach-avoidance (frontal alpha asymmetry) of 8- to 12-month-old infants as they observed a native (English) speaker and a foreign (French) speaker perform a goal-directed action (i.e., grasping objects). We further examined whether infants’ language exposure modulated these neural responses. We found that monolingual infants exhibited stronger mu desynchronization when observing a native (versus foreign) speaker perform goal-directed actions. In contrast, non-monolingual (i.e., hearing more than one language) infants did not show a difference in mu desynchronization between native and foreign speakers. No language group and exposure effects were found for frontal theta and frontal alpha symmetry.
