摘要: 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 has steadily accumulated. These have been reported to occur within latency range from 200 600 msec. Psychological constructs for these varied frequency sensitivity earlier peaks, utilization feedback information and response selection longest positivities reported. most oft-used criterion judging uniqueness a given peak scalp distribution. identification measurement distinct peaks leads problems, since interact both spatially temporally at scalp. factor analytic technique used certain cases disentangle overlapping components, with time courses resultant loading functions allowing investigator associate factors visually identified ERP components.
