Abstract: The common intersection of autism and transgender identities has been described in clinical and community contexts. This study investigates autism-related neurophenotypes among transgender youth. Forty-five youth, evenly balanced across non-autistic, slightly subclinically autistic, and full-criteria autistic subgroupings, completed resting-state functional magnetic resonance imaging to examine functional connectivity. Results confirmed hypothesized default mode network (DMN) hub hyperconnectivity with visual and motor networks in autism, partially replicating previous studies comparing cisgender autistic and non-autistic adolescents. The slightly subclinically autistic group differed from both non-autistic and full-criteria autistic groups in DMN hub connectivity to ventral attention and sensorimotor networks, falling between non-autistic and full-criteria autistic groups. Autism traits showed a similar pattern to autism-related group analytics, and also related to hyperconnectivity between DMN hub and dorsal attention network. Internalizing, gender dysphoria, and gender minority-related stigma did not show connectivity differences. Connectivity differences within DMN followed previously reported patterns by designated sex at birth (i.e., female birth designation showing greater within-DMN connectivity). Overall, findings suggest behavioral diagnostics and autism traits in transgender youth correspond to observable differences in DMN hub connectivity. Further, this study reveals novel neurophenotypic characteristics associated with slightly subthreshold autism, highlighting the importance of research attention to this group.
Abstract: The preprint is about how participatory research movement and neurodiversity movement can benefit the open scholarship movement and vice versa, leading to a more generalisable and accurate science of human behaviour and cognition.
An enduring issue in the study of mental health is identifying developmental processes that explain how childhood characteristics progress to maladaptive forms. We examine the role that behavioral inhibition (BI) has on social anxiety (SA) during adolescence in 868 families of twins assessed at ages 8, 13, and 15 years. Multimodal assessments of BI and SA were completed at each phase, with additional measures (e.g., parenting stress) for parents and twins. Analyses were conducted in several steps: first, we used a cross-lagged panel model to demonstrate bidirectional paths between BI and SA; second a biometric Cholesky decomposition showed that both genetic and environmental influences on childhood BI also affect adolescent SA; next, multilevel phenotypic models tested moderation effects between BI and SA. We tested seven potential moderators of the BI to SA prediction in individual models and included only those that emerged as significant in a final conditional model examining predictors of SA. Though several main effects emerged as significant, only parenting stress had a significant interaction with BI to predict SA, highlighting the importance of environmental moderators in models examining temperamental effects on later psychological symptoms. This comprehensive assessment continues to build the prototype for such developmental psychopathology models.
Abstract: The current study focused on the childhood to adolescence transition and sought to determine why some children are more compliant than others as well as why children comply more often with some of their parents’ rules than with others. Indices of parents’ agency and children’s agency were tested as predictors of compliance. Parent-based decision-making and parents’ responses to expressed disagreement served as indices of parents’ agency while children’s beliefs regarding the legitimacy of parents’ rules and felt obligation to obey rules served as indices of children’s agency. Parent–child dyads (n = 218; 51 % female, 49 % European American, 47 % African American) were interviewed during the summers following the children’s 5th (M adolescent age = 11.9 years) and 6th grade school years. Children who felt that their parents’ rules were more legitimate were more compliant overall than were children who felt that the rules were less legitimate. Children compiled more with rules governing topics perceived to be legitimately regulated by parents, when parents made more decisions regarding the topic and when parents responded to disagreement by standing strong. Results were generally consistent across parents’ and children’s reports of compliance and across cross-sectional and longitudinal analyses. At the transition from childhood to adolescence, only children’s agency explained why some children are more compliant than others, but parents’ and children’s agency helped to explain why children complied with some rules more than others.
