Abstract
Abstract Executive control is a broad-reaching function that includes response monitoring and is likely implemented in the frontal lobes. Age- and dementia-related changes in response-monitoring were assessed during a Picture-Name Verification Task, using response-synchronized event-related potential (ERP) markers of response monitoring: the centrally oriented error-related negativity (ERN); the smaller and more frontally-oriented correct-response negativity (CRN); and the positivity associated with errors (Pe), a marker of error awareness. These were recorded from 10 younger and 10 older healthy controls, as well as 12 Alzheimer’s disease (AD) patients. Althoug...
