| Annotation | One of the most consistent signs of normal cognitive ageing seems to be a deficit in the conscious recollection of recently experienced events. In this study, young and older participants studied two temporally distinct lists of sentences (each with two unassociated nouns). At test, in response to the nouns, participants made old-new, followed by remember (context) and know (familiarity), and source judgements. Both younger and older adults showed equivalent episodic priming effects. However, compared to the young adults, the older adults showed a greater source performance decrement than item memory performance decrement. Both age groups showed equivalent posterior-maximal old-new event-related potentials (ERP) effects. However, only the young participants produced a frontal-maximal late onset old-new effect that differed as a function of subsequent list attribution. Because source memory it thought to be mediated by prefrontal cortex, the study concluded that age-related memory differences may be due to a deficit in a prefrontal cortical system that underlies source memory and are not likely to be due to an age-related decline in episodic priming.
