AI Article Synopsis
- Aggressive behavior in middle childhood is influenced by genetic factors, but these influences can be affected by interactions with environmental factors and relationships.
- The study tested gene-environment interactions (G × E) and correlations (rGE) by examining the relationship between aggression, peer victimization, and teacher-child relationships.
- Findings indicated that children with a genetic predisposition for aggression were more likely to be victimized by peers, but having a positive relationship with their teacher helped reduce aggressive behavior linked to that genetic risk.
Article Abstract
Aggressive behavior in middle childhood is at least partly explained by genetic factors. Nevertheless, estimations of simple effects ignore possible gene-environment interactions (G × E) or gene-environment correlations (rGE) in the etiology of aggression. The present study aimed to simultaneously test for G × E and rGE processes between aggression, on the one hand, and peer victimization and the teacher-child relationship in school, on the other hand. The sample comprised 124 MZ pairs and 93 DZ pairs assessed in Grade 1 (mean age = 84.7 months). Consistent with rGE, children with a presumed genetic disposition for aggression were at an increased risk of peer victimization, whereas in line with G × E, a positive relationship with the teacher mitigated the genetically mediated expression of aggression.
