Title: Sensation seeking, impulsivity and the balance between behavioral approach and inhibition
Abstract: Impulsivity and sensation-seeking questionnaire measures are correlated and in one form of the SSS (in the ZKPQ) Imp and SS items form a reliable major factor named Impulsive Sensation-seeking (ImpSS). The correlations between impulsivity (low control) and sensation-seeking are almost entirely mediated by shared genetic factors. Biological markers for sensation-seeking, like augmenting of the evoked potential, and testosterone are also related to impulsivity. The enzyme MAO-B is related to sensation-seeking and is low in clinical disorders characterized by both traits including antisocial and borderline personality disorders and alcohol and drug disorders and bipolar disorder. High sensation-seeking is postulated to reflect strong approach and weak inhibition mechanisms in response to approach-avoidance conflicts. The former is a function of dopaminergic and the latter to serotonergic systems. The likelihood of risky behavior, as in driving, sports, drug abuse, volunteering, and sex depends upon the balance between the two systems.
