Specific subtypes of externalizing behavior problems, reactive and proactive aggression, have been uniquely related to specific risk factors, correlates, and consequences. The purpose of this study was to examine the relations between social cognitive skills, intelligence, and reactive and proactive aggression in elementary school-aged children. These children were at risk for developing serious externalizing behavior problems and recruited within a program focused on reduction and prevention of delinquency, led by the municipality of Amsterdam in The Netherlands. Intelligence and social cognitive skills tasks were administered in fifteen boys in the ages of 7-12 years (M = 10.38, SD = 1.95). The results from the present study indicate that the relation between intelligence and reactive aggression is mediated by social cognitive skills, and more precisely the ability to identify emotions. No such relations were found for proactive aggression or other social cognitive skills. It is concluded that the relation between social cognitive skills and aggressive behavior depends at least partly on intelligence and that interventions for reactive-aggressive children should focus on training of emotion recognition without losing sight of the important role of intelligence.Show less

Furthermore, the moderating and mediating effects of social skills on the relationships between social cognition, executive functioning and internalizing/externalizing behaviour were examined. The sample consisted of 286 children from regular primary schools in the Netherlands. Both direct and indirect measures of social cognition (Theory of Mind, emotion recognition and social cognitive skills in daily life) and executive functioning (inhibitory control, visual spatial working memory, verbal fluency, planning abilities and EF in daily life) were used in the study. Social skills and psychopathology were measured using parent-rating scales (SSRS and CBCL respectively). Problems in the domain of social cognition and executive functioning, as well as internalizing and externalizing behaviour problems were highly correlated. Also, social skills were highly correlated with psychopathology. Social cognition only predicted internalizing behaviour, whereas executive functioning only appeared to be a unique predictor of externalizing behaviour. Moderation and mediation models demonstrated social skills to be a moderator and partial mediator in the relationship between executive functioning and externalizing behaviour problems. Mediation analyses indicated the relationship between social cognition and externalizing behaviour to be fully mediated by executive functioning. The results of this study suggest that training social skills may be important for children who show deficits in executive functioning and who are at risk for developing externalizing behaviour problems. Furthermore, the mediating role of executive functioning on the relationship between social cognition and externalizing behaviour possibly explains the absence of a moderating/mediating effect of social skills on the relationship between social cognition and externalizing behaviour problems. For more knowledge on precursors of psychopathology, future studies should focus on atypically developing children, should examine the prediction of specific psychiatric disorders, examine the possible differential results from direct and indirect measures and examine the development of the social cognition, executive functions, social skills and psychopathology in middle and late childhood, and during adolescence.Show less

Method: We used the Finger Tapping Task (FTT) to assess maturation of the brain as measured by fine motor speed, and lateralization of the brain as measured by the difference in speed between both hands. Both maturation and lateralization are used as a measure of specialization of the brain. The participants were children in the age of 5 to 18 years old and were assigned to five distinct diagnostic groups: Mood problems (n=178), Behavior problems (n=82), Autism spectrum Disorders (n=106), Attention Deficit Hyperactivity Disorder (n=190) and Learning problems (n=44). The diagnostic groups differ with regard to age and gender. Results: We found that children with an autism spectrum disorder show delayed fine motor lateralization. We were also able to determine that the differences in fine motor speed between the different diagnostic groups get larger with age indicating that delayed maturation gets more evident while children get older. Looking at the academic measures, we found that a more matured brain, as measured with fine motor speed, is associated with better academic performance, even when controlled for age. Conclusion: Autism spectrum disorders can be differentiated from other disorders when looking at lateralization of the brain. A more matured brain is associated with a significant higher level of academic performance for math, reading and Writing.Show less
