Harsh parenting, operationally defined as verbal aggression and corporal punishment, has been associated with negative child behaviors like poor emotional regulation and externalizing behavior. The present study sought to examine the structural consequences of harsh parenting styles on children's brains specifically with regard to parental actions considered normative (i.e. non-abusive) but still negative in valence. A significant association was determined between non-harsh parenting and thickening in the prefrontal cortex, suggesting a need for further investigation into this region.
