The impact of Yohimbine-induced arousal on facets of behavioural impulsivity.

ABSTRACT:

Rationale

State-dependent changes in physiological arousal may influence impulsive behaviours.

Objectives

To examine the relationship between arousal and impulsivity, we assessed the effects of yohimbine (an α₂-adrenergic receptor antagonist, which increases physiological arousal via noradrenaline release) on performance on established laboratory-based impulsivity measures in healthy volunteers.

Methods

Forty-three participants received a single dose of either yohimbine hydrochloride or placebo before completing a battery of impulsivity measures. Blood pressure and heart rate were monitored throughout the study.
