title: When Greta Garbo is easier to remember than Stefan Edberg: influences of prior knowledge on recognition memory in Alzheimer's disease.
abstract: This study investigated the effects of prior knowledge on recognition memory in patients with a mild Alzheimer's disease. Normal older adults and mildly demented patients were presented with dated and contemporary famous faces with name tags and were asked to generate unique statements about each person. Results indicated that both groups generated more statements about the dated than about the contemporary figures. Most important, both groups performed better with the dated than with the contemporary faces in an unexpected episodic face recognition task. This pattern of results suggests that both groups (a) possess more knowledge of dated than of contemporary famous individuals and (b) are able to utilize prior knowledge to enhance episodic remembering. Viewing these results in light of other recent work, it is concluded that differences between normal old and mildly demented individuals in the ability to utilize cognitive support for remembering may be differences in degree.
