Sensation seeking, recognition memory, and autonomic arousal

Substantial evidence shows that sensation seeking impacts memory; however, research has not examined how sensation seeking impacts automatic familiarity and conscious-controlled recollection memory systems. The present study (N = 80) examined high and low sensation seekers’ familiarity and recollection of high and low arousal images with negative valence using behavioral and skin conductance measures. Low sensation seekers had more accurate familiarity judgments to high than low arousal images, reflecting a heightened aversive motivational system. High sensation seekers showed an opposite pattern with memory enhancement for low arousal images, regardless of old–new status. The lack of any sensation seeking effects in relation to recollection judgments suggests that this personality trait is more influential on automatic than conscious controlled memory systems.

► Sensation seeking examined during familiarity and recollection memory. ► Low sensation seekers increased accuracy for high arousal images. ► High sensation seekers memory enhancement for low arousal images. ► Sensation seeking affected familiarity but not recollection.
