Abstract

The gambling task is a valid predictor of various risk-taking behaviors. However, the neural underpinnings of risk processing in addiction are yet unclear. The present event related potential (ERP) study examined electrophysiological correlates associated with different stages of risky reward processing in risk-taking behavior. Ten female heroin addicts (HA) and ten female normal controls (NC) performed a simple two-choice gambling task. Behaviorally, whereas HA exhibited a risk-increase pattern, NC showed a risk-neutral pattern. During the anticipation stage, an increased stimulus-preceding negativity was elicited by high-risk compared to low-risk choices in HA and NC. Furthermore, HA as compared to NC exhibited a diminished P300 to both gains and losses.
