We assessed the influence of the variables outcome potential, feedback valence, magnitude, and probability on the amplitude of the feedback negativity (FN). Outcome potential was defined as the a priori valence of an upcoming feedback, that is, is there a potential win or potential loss? All these variables have been studied previously, although never(More)
Previous research has shown that pathological gamblers show various cognitive distortions, especially in interpreting near losses.

We assessed the event-related brain potentials (ERPs) of 20 problem gamblers and 21(More)
