Abstract
Alexithymia and low emotion differentiation restrict access to emotional information and increase propensity toward dysregulated and deviant behaviors, such as impulsive aggression. However, mechanisms underlying such effects are largely unknown. This study examined the mediating role of emotion regulation in the relationship between restricted access to emotional information and impulsive aggression. Alexithymic features and emotion differentiation explained 43% of the variance in impulsive aggression; these relationships were fully mediated by emotion-regulation difficulty. Contrary to previously held assumptions, alexithymic features and emotion differentiation were uncorrelated with one another, each limiting the translation of unique emotion information necessary for adaptive emotion and behavior regulation.
