Ventrolateral Prefrontal Cortex Activation During Social Exclusion Mediates the Relation Between Intolerance of Uncertainty and Trait Aggression

Intolerance of uncertainty (IU) is an important individual difference factor that may contribute to trait-like aggression. Deficient engagement of the ventrolateral prefrontal cortex (vlPFC) during social situations may also be a mechanism that links these two constructs. The aim of the current study was to test a proposed mediation model whereby IU is associated with trait aggression through neural activation of the vlPFC during a social...
