Dysfunctional reward processing in male alcoholics: an ERP study during a gambling task.
OBJECTIVE A dysfunctional neural reward system has been shown to be associated with alcoholism. The current study aims to examine reward processing in male alcoholics by using event-related potentials (ERPs) as well as behavioral measures of impulsivity and risk-taking. METHODS Outcome-related negativity (ORN/N2) and positivity (ORP/P3) derived from a single outcome gambling task were analyze...
متن کاملReward processing deficits and impulsivity in high-risk offspring of alcoholics: A study of event-related potentials during a monetary gambling task.
BACKGROUND Individuals at high risk to develop alcoholism often manifest neurocognitive deficits as well as increased impulsivity. The goal of the present study is to elucidate reward processing deficits, externalizing disorders, and impulsivity as elicited by electrophysiological, clinical and behavioral measures in subjects at high risk for alcoholism from families densely affected by alcohol...
متن کاملDysfunctional Reward Processing in Depression.
Anhedonia - diminished pleasure and/or decreased reactivity to pleasurable stimuli - is a core feature of depression that frequently persists after treatment. As a result, extensive effort has been directed towards characterizing the psychological and biological processes that mediate dysfunctional reward processing in depression. Reward processing can be parsed into sub-components that include...
متن کاملReward Processing Deficits During a Spatial Attention Task in Patients With ADHD: An fMRI Study.
OBJECTIVE In this study, we aimed to explore how cues signaling rewards and feedbacks about rewards are processed in ADHD. METHOD Inside the scanner, 16 healthy children and 19 children with ADHD completed a spatial attention paradigm where cues informed about the availability of reward and feedbacks were provided about the earned reward. RESULTS In ventral anterior thalamus (VA), the contr...
متن کاملNeural correlates of facial expression processing during a detection task: An ERP study
Given finite attentional resources, how emotional aspects of stimuli are processed automatically is controversial. Present study examined the time-course for automatic processing of facial expression by assessing N170, and late positive potentials (LPPs) of event-related potentials (ERPs) using a modified rapid serial visual presentation (RSVP) paradigm. Observers were required to confirm a cer...
