Dynamic social envirotypes demonstrate adolescent brain dysconnectivity is contextual
These findings suggest that dysconnectivity is contextual: there is no single brain connectivity pattern that is universally associated with better mental health.
PreprintGenome-wide analysis of social behaviour across social domains, reporters and developmental stages: a meta-regression approach
We modelled heterogeneity in single-variant associations across social domains (low prosocial behaviour and peer/social difficulties), multiple informants (parents, teachers and self-reports) and ages (2–29 years), identifying 6 associated loci, including variation within CADM2 ( P = 2.51 × 10 −9 ).
Revista con revisión por paresParent-Child Cortical Similarity Indexes Multiple Dimensions of Sensitivity in the Association Between Family Environment and Adolescent Internalizing Symptoms
Parent-child cortical similarity may index a dyadic component of this sensitivity, one not adequately represented by a single similarity score but distributed across forms of similarity and cortical systems.
PreprintDimensional and Categorical Predictors of Theory of Mind Network Activation: A transdiagnostic fMRI Study in Psychiatric Inpatients
Subsequent Bayesian analysis of covariance (ANCOVAs) consistently favoured models that excluded traditional categorical diagnoses, suggesting that dimensional measures, especially Total Problems and Internalising, provided substantially greater predictive utility for ToM-related regional brain activation.
PreprintA self without a "we": Individuals with Borderline personality disorder show signatures of disrupted social basis functions
Together, this suggests that BPD is characterized by an unbalanced representation of social structure, with an attenuated "we" alongside a heightened "they".
PreprintThe role of sleep in the retention and long-term maintenance of newly formed ability self-beliefs
However, after three weeks, participants who slept after belief formation showed a shift towards more positivity for the initially formed low ability self-beliefs.
PreprintChildhood Trauma and Transdiagnostic Mental Health Outcomes Among Adults in 17 Arab Countries: A Multinational Cross-Sectional Study Using a Latent Global Trauma Model
Conclusions: Childhood trauma is highly prevalent across the Arab region and is strongly associated with multiple dimensions of psychological distress, highlighting the urgent need for trauma-informed prevention, screening, and early intervention programs in the Arab region.

Results: Here we show that associations between autonomic regulation, interoception, and psychopathology differ by sex.
PreprintA convergent behavioral-neural profile of parental dysregulation and the link between parent-child brain-state similarity and child negative affect
These findings suggest that dyadic neural similarity should be interpreted in context: resembling a parent with a dysregulated profile may confer risk rather than protection.
PreprintToward an Objective Assessment of Fight-or-Flight System Function in Anxiety Disorders: Startle Reflex Modulation in Threat Coping Contexts as a Candidate Neurophysiological Marker of Disrupted Defense System Operation
Results: Anxiety and worry were higher in participants with enhanced no-control and escape startle than in participants with enhanced no-control but not escape startle.
PreprintCross-Modal Organization of Facial and Vocal Behavior Revealed by Coordination Metrics Derived from Temporal Alignment
Our findings support alignment-derived metrics as a complementary approach for characterizing individual variability in facial-vocal expressive behavior.
PreprintMenstrual cycle phase and premenstrual symptoms in relation with the stress response: an fMRI study
Conclusion: Using a within-subject repeated-measures design, we found neural responses to psychosocial stress to be stable across menstrual cycle phases.
