Abstract

Appropriate processing of feedback information is critical for human executive functions that guide goal-oriented behavior. Feedback-related negativity (FRN) measurements are feedback signals that are recorded through the scalp and convey unpredicted bad/negative information. This study attempts to characterize FRN in the context of individual psychological disposition, specifically impulsivity. The results show that non-planning individuals produce smaller FRN signals than planning individuals when performing both monetary (experiment 1) and non-monetary (experiment 2) gambling tasks, suggesting that impulsive individuals are prone to make risky choices and to show less evaluation processing and lower negative feedback. Furthermore, the clinical utility of FRN measurements was examined with regard to assessing frontal lobe functions in patients with brain lesions. Reductions in FRN amplitudes in response to go-nogo tasks were associated with impaired inhibition responses. These findings suggest that FRN measurements are useful for electrophysiological assessments of patients with impaired inhibitory control.

Theme 1: Frn And Impulsivity

Impulsivity is a trait that, lacking forethought regarding possible outcomes, yields hasty and unplanned responses to internal or external stimuli (Moeller, Barratt, Dougherty, Schmitz, & Swann, 2001). In studies exploring the neurobiological bases of impulsivity, measurements of impulsivity are usually based on the reward-discounting model, in which impulsivity is defined as the inability to wait for a delayed, more substantial reward (Monterosso & Ainslie, 1999), or the rapid-response model, in which impulsivity is defined as responding without adequate assessment of context (Yeung & Sanfey, 2004). We hypothesized that FRN responses might be a marker of impulsivity, because impulsive individuals fail to learn from negative feedback. In the first study, we investigated the relationship between self-reported impulsivity and subtracted FRN during monetary gambling tasks in healthy adults (Onoda, Abe, & Yamaguchi, 2010).
