Theoretical Overview of P3a and P3b

  • Chapter
Detection of Change

Abstract

Recent empirical advances on the relationship between the P3a and P3b event-related brain potentials (ERPs) have suggested a plausible approach to how these potentials may interact. The purpose of this chapter is to review the issues surrounding these developments. The chapter is organized into several sections: First, the empirical background of the P3a and P3b subcomponent distinction is limned. Second, a theoretical perspective of P300 is presented. Third, the neuropsychological basis for the P300 component is outlined in terms of how these subcomponents may be related. The goal is to provide a theoretical overview of the topic areas by integrating prior findings with current perspectives.
