Abstract
Publisher Summary This chapter discusses multiple positive event-related potential (ERP) components in visual discrimination tasks. The evidence that the ERPs elicited during task-oriented paradigms consist of several late positive components has steadily accumulated. These components have been reported to occur within the latency range of from 200 to 600 msec. Psychological constructs for these components have varied from frequency sensitivity for the earlier of these peaks, to utilization of feedback information and response selection for the longest latency positivities reported. The most oft-used criterion for judging the uniqueness of a given peak has been scalp distribution. The visual identification and measurement of distinct peaks leads to problems, since components interact both spatially and temporally at the scalp. The factor analytic technique has been used in certain cases to disentangle these overlapping components, with the time courses of the resultant loading functions allowing the investigator to associate factors with visually identified ERP components.
