A Comparison of Normal Versus Cognitively Impaired Geriatric Medical Patients Aging, Neuropsychology, and Cognition 1997, Vol. 4, No. 1, pp. The design of the study includes three waves of data collection.
Subjects take part in extensive health and memory examinations, and interviews about social factors.
The memory testing covers a wide range of memory functions.

Perceptual skill acquisition within the context of a mirror reading task was unaffected by age, while word stem completion priming tended to decline across the age groups. The present findings indicate dissociable effects of normal aging on explicit and implicit memory, and thereby some degree of qualitative resemblance to human amnesia.
