Atypical reward anticipation in impulsive individuals: evidence from EEG and experiential delay discounting.

ABSTRACT:

Background

Impulsivity is characterized by impaired inhibition of thoughts and actions and a reduced ability to weigh the consequences of behavior. Importantly, impulsivity has been associated with altered reward processing and reward anticipation.

Methods

We aimed to investigate neurophysiological indices of impulsive behavior using an experiential delay discounting task with 64-channel EEG in neurotypical adults (n = 54). Impulsive behavior was operationalized as the preference for smaller, immediate rewards over larger, delayed rewards with the delay varied from 1 to 30 s in different blocks.

Results

We registered feedback-related fronto-central theta and centro-parietal delta power, although did not find any correlation between impulsive behavior and these
