A Twin Study of the Relationship Between Inhibitory Control and Behavior Problems

Inhibitory control is an important part of successfully functioning in society. Low inhibitory control is related to behavior problems in adolescents. However the etiology of this relationship is unclear. In this study we use a genetically informative twin sample to disentangle the genetic and environmental effects that influence this association. We conclude that there is a significant genetic component in the relationship between inhibitory control and externalizing problems, but not internalizing problems.
