DSM-5 personality trait domains and withdrawal versus approach motivational tendencies in response to the perception of other people’s desperation and angry aggression

Abstract

Expressions of affect communicate social messages, which trigger approach and withdrawal/avoidance motivational tendencies in the observer. The present study investigated relationships between inter-individual differences in the motivational responses to other people’s affect expressions and DSM-5 personality trait domains. State-dependent, transient EEG alpha asymmetry responses provided indicators of the relative activation of withdrawal versus approach motivation in the respective social-emotional contexts. The Personality Inventory for the DSM-5 (PID-5) was used for the assessment of personality traits in a non-clinical sample. Individuals with higher levels of Antagonism showed relative activation of approach versus withdrawal motivation (as indicated by less relative right frontal activation) in response to confrontation with auditory expressions of angry aggression, whereas participants with higher levels of Detachment showed relative activation of withdrawal versus approach motivation (as indicated by greater relative right frontal activation) to the perception of other people’s desperate crying.
