SOURCE MEMORY FOR ACTIONS IN ALZHEIMERS-DISEASE

A source memory task, using everyday objects in actions performed by e ither the participant or the experimenter, was given to probable Alzhe imer's disease (AD) and elderly normal (EN) individuals. When the over all recognition performance of the two groups was made equivalent by i ncreasing the test delay intervals for the control group, EN and AD pa rticipants showed similar patterns of correct and incorrect responses. Moreover, both groups showed evidence of a generation effect and of a n advantage for items repeated at study. The findings of this study su ggest that, for a given level of event memory, memory for the source o f the events is comparable between EN and AD individuals.
