Event-related potential evidence for attentional inhibition of return in audition.

abstract：:Recent studies of electroencephalogram event-related potentials reported aberrant feedback-related negativity (FRN) in neurological and psychiatric diseases, such as alcoholism and attention-deficit hyperactivity disorder. These diseases are characterized by high impulsivity. We investigated the relationship between F...
