Assessment of Memory Functioning among an Aging Sample

Abstract

To provide additional basic normative data and an enhanced understanding of memory functioning of older individuals, 100 subjects equally divided into 5-yr age intervals from 60 to beyond 80, evenly split by sex and socioeconomic status, and balanced for racial composition were tested on 19 memory measures commonly used in clinical and neuropsychological assessment. While analyses indicated that 10 measures were significantly related to age, performance was quite stable from 60–74 years, dropping primarily at the oldest age intervals. No significant age-related differences were found on the remaining 9 measures, and in all instances considerable variability was evident. The study provides evidence against stereotypes that our population as a whole shows a generalized or severe memory decline with advancing age. Clearly, no one should hastily assume limitations in memory which would routinely disqualify older individuals in work, independent living, and decision-making. Recommendations are made for practicing clinicians who must choose instruments appropriate for normal and abnormal subjects.
