The effect of aging on prospective memory was examined. Fifty older subjects and 69 college students were given measures of both retrospective memory and the Wood Prospective Memory Test. It was found that: 1) The reliability of the WPMT subscales was lower than that required for clinical applications; 2) The WPMT subscales correlated significantly with several measures of retrospective memory; 3) There was a tendency for the WPMT subscales to have low, positive but non-significant correlations with the remaining measures of retrospective memory; 4) A self-report questionnaire on prospective memory did not correlate significantly with measures of either prospective or retrospective memory; 5) The older subjects significantly outperformed the younger subjects on the WAISR Vocabulary subtest, but performed significantly more poorly on the WPMT subscales and almost all other measures.
