Recent research suggests that people have a strong urge to seek such counterfactual information (counterfactual curiosity), even though it can lead to negative emotions, such as regret. In the present study, we used an adapted Balloon Analogue Risk Task with functional magnetic resonance imaging to investigate brain regions associated with counterfactual curiosity. We replicated previous behavioral findings that people are willing to find out counterfactual information (how much more they could have won) after winning their game. We also observed the emotional cost associated with counterfactual curiosity, such that participants felt stronger negative emotions after seeking counterfactual information. Brain imaging results revealed that the choice to seek counterfactual information is associated with stronger activity in the caudate, brain regions implicated in processing of intrinsic and extrinsic rewards. In addition, the caudate and the nucleus accumbens showed greater activity when participants realized that they could have won more points. These results suggest that the striatum plays a crucial role in seeking and processing counterfactual information.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13213454/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147489031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To better understand variation in brain-environment coupling and its associated outcomes, we identified 'social envirotypes', or different patterns of social environment experience, in the Adolescent Brain Cognitive Development Study by hierarchically clustering subjects. Two focal clusters, which accounted for 89.3% of all participants, differed significantly on eight out of nine youth-report social environment quality measures, representing almost perfect complements. We then applied tools from network neuroscience to show different social envirotypes are associated with different patterns of whole brain functional connectivity. Differences were distributed across the brain but were especially prominent in Default and Somatomotor Hand systems for these focal clusters. Finally, we examined how social envirotypes change over development and how these patterns of change are associated with a suite of outcomes. The resulting dynamic social envirotypes differed along dimensions of stability and quality, but outcomes diverged based on stability. Altogether, our findings represent significant contributions to both social developmental neuroscience and network neuroscience, emphasizing the variability and dynamicity of brain-environment coupling and its consequences.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13157345/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146108907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a pharmacoimaging study to examine ayahuasca's effects on a key theory of mind region, at the core of the third visual pathway (TVP)-the posterior superior temporal sulcus (pSTS), which is involved in facial emotion recognition and social perception. Twelve healthy participants (mean age: 40 ± 6.6 years; four females) completed a crossover design with three conditions: 0.5 mg/kg N, N-dimethyltryptamine (DMT), 0.8 mg/kg DMT, and placebo, with 1-2 months washout intervals. Resting-state functional magnetic resonance imaging (fMRI) was used to assess pSTS functional and effective connectivity. The highest dose significantly increased right pSTS connectivity and directed modulation from visual (primary and extrastriate cortices) and mirror neuron regions (supplementary motor cortex; SMC). Subjectively, this enhanced social cognitive states, with a strong positive correlation between pSTS-SMC connectivity and perspective-taking experiences. Additionally, ayahuasca produced positive psychological effects, including improved perceived social relationships, at 1-week follow-up despite minimal acute effects. Our findings reveal a novel mechanism of action of psychedelics at early stages of social information processing, with enhanced integration of the TVP and mirror neuron systems. The pSTS emerged as a critical hub supported by top-down and bottom-up evidence, providing a basis for understanding ayahuasca's prosocial therapeutic effects.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12936398/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146097737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, work investigating the mentalizing network often relies on non-naturalistic methods, limiting our understanding of individual differences most apparent within social interaction contexts. We took a naturalistic, multilevel approach to investigate relations between real-world affective expressions, social anxiety symptoms and mentalizing network connectivity. Same gender-identity friend pairs (40 participants; 62.5% Women; 87.5% White) engaged in a social interaction while videos from their individual visual perspectives were recorded. Participants were later scanned while they watched clips of the interaction from their own (self run) and their friend's (friend run) perspective. We found that expressed negative affect, not expressed positive affect, related to within-person variation in mentalizing network connectivity across perspectives. Further, participants higher in social anxiety symptoms showed more consistent mentalizing network connectivity across perspectives when expressed negative affect was higher than average, and particularly when friend negative affect expressions, rather than their own negative affect expressions, were higher. Mentalizing network connectivity may be responsive to shifts in negative affect during social interactions and individuals with higher social anxiety may find negative affect from a friend particularly salient.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13166882/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147701455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prior research has yielded mixed results, particularly regarding arousal. Using functional magnetic resonance imaging (fMRI), we examined neural responses to emotional video clips in adults with ASD (n = 20) and typically developing controls (n = 20). Stimuli were designed to elicit controlled emotional responses with standardized visual and narrative features, and parametric modulation analyses assessed neural activation as a function of self-reported arousal and valence. Behavioral ratings confirmed stimulus validity. For arousal, typically developing individuals showed widespread modulation across frontal, parietal, temporal, and subcortical regions, including the cingulate gyrus, insula, caudate, and ventral tegmental area. In contrast, ASD participants exhibited restricted modulation, primarily within the anterior cerebellum. No group differences emerged for valence, with both groups recruiting frontal and limbic regions such as the amygdala and insula. These findings highlight a dissociation between arousal and valence processing in ASD. Reduced cortical engagement and increased anterior cerebellar (including the vermis) involvement during arousal suggest compensatory mechanisms, underscoring the importance of distinguishing emotional dimensions when characterizing neural processes in autism.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13221250/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147679916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Still, the contexts in which these differences occur (e.g. social and non-social) and the extent to which they relate to autistic traits remain poorly understood. Notably, current frameworks for reward processing have yet to describe the impacts of reward processing differences on broader cognitive domains in autism. Evidence from studies of neurotypical individuals and non-human primates shows that reward has significant impacts on multiple cognitive domains, including executive control processes that have been linked to core social communication and repetitive behavior traits in autism. These findings suggest that examining reward processes in relation to cognitive functions in autism may provide important insights into neural systems that contribute to multiple developmental abilities and psychiatric features common to autism. In this review, we present a new, testable model that describes how interactions between reward and cognitive domains may have additive or synergistic contributions to key clinical traits in autism. This model is framed in context of existing evidence for reward processing differences in autism and their relationship to clinical features, as well as broader implications for expanding existing reward-based frameworks in this population.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13649182/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148972888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the causal contributions of the dorsomedial prefrontal cortex (dmPFC) and posterior parietal cortex (PPC) to self-other episodic memory and metacognition using focal transcranial direct current stimulation (tDCS). One hundred participants completed an incidental encoding task in which trait adjectives were rated with reference to the self, a close friend, or a celebrity, under anodal or sham stimulation to either region. Recognition tests assessed item and source memory sensitivity (d') and metacognitive efficiency (meta-d'/d') as a function of agent and emotional valence. Across stimulation conditions, a graded advantage for self-related information was observed in both item and source memory, extending to metacognitive efficiency. Anodal stimulation to either region attenuated the SRE, with significant effects at the dmPFC. PPC stimulation additionally biased source memory away from positive and towards negative information. These findings demonstrate shared and dissociable causal roles of dmPFC and PPC in self-other episodic memory.","PeriodicalId":94208,"journal":{"name":"Social cognitive and affective neuroscience","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13592675/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148820612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They subsequently completed an EEG-based Think/No-Think (TNT) task, where they either retrieved or suppressed the retrieval of aversive scenes in response to Think or No-Think object cues while reporting any intrusions they experienced. Different from our initial hypothesis, preregistered analyses showed that during retrieval suppression, reappraised memories were associated with larger centro-parietal P300 than watched scenes. Consistently, in the post-TNT recall test, participants recalled more details and reported lower negative emotions related to these reappraised scenes than the watched scenes. These results suggest that cognitive reappraisal may preserve the episodic content of negative memories while lessening their emotional impact during recall. This finding holds significant clinical potential, as it could enable individuals to retain valuable information from adverse experiences without being overwhelmed by distress.

In an functional MRI (fMRI) study of 82 young adults, participants viewed negative images with instructions to passively observe or cognitively reappraise them. We applied PINES and extracted amygdala activation levels. Amygdala activation did not differ between conditions (d = 0.16, P > .1), but PINES level was reduced during the cognitive reappraisal relative to passive viewing (d = 0.27, P = .02). An interaction test between condition and brain measure was not significant. Decreased PINES level was associated with lower negative affect (ρ = 0.27, P = .02), and PINES showed a significantly stronger relationship with negative affect relative to amygdala activation (P = .005).

Forty-one participants performed the experiment, with electroencephalography (EEG) and eye-tracking data simultaneously recorded. By aligning EEG with eye-tracking data through time-locked analyses, we characterized oscillatory dynamics at each hierarchy level, integrating single-frequency (power spectral density, PSD) and cross-frequency (phase-amplitude coupling, PAC) features. Results showed that increasing hierarchical demands enhanced PSD across multiple frequency bands in both emotional and non-emotional contexts. Both contexts also exhibited enhanced narrowband delta-beta PAC with increasing abstraction. Importantly, emotional hierarchical demands additionally elicited PAC patterns beyond those in non-emotional contexts, such as delta-alpha and alpha-beta couplings. Topographical clustering revealed that emotion-related PAC activity predominated in fronto-parietal and temporo-occipital regions. These findings suggest that while the brain utilizes general neural dynamics for processing abstract goals, emotional demands recruit additional neural resources to support it.
