This study investigates brain age differences in youth with conduct disorder compared to controls, finding accelerated brain maturation in those with adolescence-onset CD.

The paper assesses bias in polygenic prediction of externalising behaviours using twin-pairs, finding minimal rGE bias but less variance prediction for callous-unemotional traits.

This study examines the effects of regular cannabis use on brain resting-state functional connectivity in adolescents and adults, finding localized increases in the executive control network in users but no significant age-group interactions.

This study identifies genetic variants associated with antisocial behavior through a genome-wide association meta-analysis, finding significant links to FOXP2 and correlations with multiple health and behavioral traits.

This paper improves the prediction of behaviour problems using multi-GPS, cross-age and cross-rater composites, increasing predictive variance from less than 2% to up to 6%.

The paper shows that cooperative social learning improves with age, while uncooperative learning remains stable, highlighting early adolescence as a critical period for social behavior development.
