ABSTRACT
The general focus of the research described in this chapter is on understanding the role in higher cognitive processes played by two low-level reflexes—prepulse inhibition (PPI) and the orienting response (OR). Specifically, this research had two primary aims: to examine event-related potential (ERP) components under prepulse conditions as part of a broader effort to determine how PPI affects higher level perceptual processes, and to determine whether localized and generalized orienting are associated with attention-sensitive ERP components.
