Performance differences in reaction tasks are reflected in event-related brain potentials (ERPs)

摘要

Event-related potentials (ERPs), which can be extracted from the elecroence- phalogram (EEG), are assumed to reflect distinct cognitive processes in real time. Hence ERP analysis could be used in cognitive ergonomics as a tool to specify, for Example, bottlenecks or sources of individual performance differences. Such Specific results may be helpful to change the tasks or train the subjects specifically. In the present exploratory study, the authors investigated whether subjects with Large spontaneous differences in performance accuracy, as defined by their error Rates in a speeded binary choice reaction task, also differ in the structure of their ERPs.
