| Sumario: | A study examined differences in intracortical asymmetry and predicted that individuals with greater left relative to right dorsolateral prefrontal activity would show a more approach-motivated response to social rejection. Data were obtained from 84 female participants randomly tasked to one of three stressful situations: social rejection, social evaluation without rejection, or self-evaluation. Findings revealed that among participants assigned to the social-rejection condition, greater left relative to right prefrontal intracortical activity at baseline was linked to more adaptive cardiovascular profiles and more self-reported approach-oriented emotions. Findings indicated that participants in the other conditions did not exhibit these relationships. Findings are discussed in detail.
