Summary: According to a new study, children with executive function deficits were more likely to show physical and reactive aggression later in life. Researchers suggest helping children to improve executive function could help to reduce aggression levels.Source: Frontiers.A new study finds that deficits in executive function — a measure of cognitive skills that allow a person to achieve goals by controlling their behavior — predicts later aggressive behavior. The study, published in Frontiers in Behavioral Neuroscience, shows that primary school children with lower executive function were more likely to show physical, relational and reactive aggression in later years, but not proactive aggression. The increased aggression — which was observed in both boys and girls — may be partly due to an increased tendency for anger in these children. The findings suggest that helping children to increase their executive function could reduce their aggression.Aggression during childhood can create a variety of challenges for children and their parents, siblings and classmates. Understanding the basis for aggression — and how it develops over childhood — could help researchers to identify ways to reduce aggressive behavior.Executive function includes skills for adapting to complex situations and planning, including exerting self-control in challenging situations. Previous studies have shown that antisocial behavior is related to lower executive function, and it is unsurprising that improving executive function could help to reduce aggression. However, few studies have examined the link between childhood executive function and aggression over time. Similarly, researchers do not yet understand the relationships between executive function, specific types of aggression and other contributing factors, such as how easily someone becomes angry.In this new study, researchers at the University of Potsdam in Germany investigated the relationship between childhood executive function and different types of aggression, to see if deficits in executive function could predict aggressive behavior in later years.The research team assessed German primary school children aged between 6 and 11 years old at three time points: the start of the study, around 1 year later and around 3 years later. The children completed behavioral tasks to reveal different aspects of their executive function, including memory, planning abilities and self-restraint.The researchers also asked the children’s teachers to record their tendency for different types of aggression. These included physical aggression, relational aggression (where a child might socially exclude someone or threaten to end a friendship), reactive aggression (where a child reacts aggressively to provocation) and proactive aggression (where a child is aggressive in “cold blood” without being provoked). Finally, the children’s parents completed a survey detailing how easily the children tended to get angry.“We found that deficits in executive function affected later physical and relational aggression,” said Helena Rohlf, the lead author on the study. “The more deficits children showed at the start of the study, the higher their aggression one and three years later.”Rohlf and her colleagues also found that an increased tendency for anger in children with reduced executive function may partly explain their increased aggression in later years.The findings suggest that training programs that help children to increase their executive function, and manage their anger, could reduce their aggression.

The researchers plan to conduct further work to see if their results also apply to children with serious levels of aggression.[divider]About this neuroscience research article[/divider]See alsoFeaturedGeneticsNeuroscienceOpen Neuroscience Articles·March 2, 2020The functioning amyloid in a healthy brainSource: Barbara Krahé – Frontiers Publisher: Organized by NeuroscienceNews.com.

However, there is a lack of longitudinal studies that have examined the effect of deficits in EF on aggression over time and taken into account different forms and functions of aggression at the same time. Furthermore, only few studies have analyzed the role of underlying variables that may explain the association between EF and aggression. The present study examined the prospective paths between EF and different forms (physical and relational) and functions (reactive and proactive) of aggression. The habitual experience of anger was examined as a potential underlying mechanism of the link between EF and aggression, because the tendency to get angry easily has been found to be both a consequence of deficits in EF and a predictor of aggression. The study included 1,652 children (between 6 and 11 years old at the first time point), who were followed over three time points (T1, T2, and T3) covering 3 years. At T1, a latent factor of EF comprised measures of planning, rated via teacher reports, as well as inhibition, set shifting, and working-memory updating, assessed experimentally. Habitual anger experience was assessed via parent reports at T1 and T2. The forms and functions of aggression were measured via teacher reports at all three time points. Structural equation modeling revealed that EF at T1 predicted physical, relational, and reactive aggression at T3, but was unrelated to proactive aggression at T3. Furthermore, EF at T1 was indirectly linked to physical aggression at T3, mediated through habitual anger experience at T2. The results indicate that deficits in EF influence the later occurrence of aggression in middle childhood, and the tendency to get angry easily mediates this relation.[divider]Feel free to share this Neuroscience News.[/divider]Join our Newsletter I agree to have my personal information transferred to AWeber for Neuroscience Newsletter ( more information )Sign up to receive the latest neuroscience headlines and summaries sent to your email daily from NeuroscienceNews.comWe hate spam and only use your email to contact you about newsletters.
