The Relationship between the Error-Related Negativity (ERN) and Mental Resource Allocation in the Error-Related Processes

摘要

Recent electrophysiological studies in humans have reported a component of the event-related brain potential (ERP), the error-related negativity (ERN), that occurs when subjects make errors in choice reaction time tasks. The ERN has a frontocentral scalp distribution and peaks within 80-110 msec after the response. The ERN is related to the error detection process. In addition, recent studies have suggested that the ERN amplitude might reflect the resource allocation. The present study examined whether or not the ERN reflects perceptual resource allocated to the error detection by using the single and dual-tasks.
