Optimal recall in early and late adulthood

Mäntylä & Nilsson (1983) recently presented a striking empirical phenomenon demonstrating a practically perfect recall of verbal materials encountered at one single trial and without specific instructions to learn the items. The purpose of the study to be presented in this article was to investigate whether older adults are capable of performing at the same high level of recall as younger adults did in the Mäntylä & Nilsson study. Type of instructions and number of retrieval cues were included in the experimental design, in addition to the age factor. Although the results indicated a superior memory performance of younger adults as compared to older adults, the latter group of subjects demonstrated an extremely high level of recall as well. Both age groups showed quite similar recall patterns in the sense that no interaction effects between the age factor and the other independent variables were obtained. The data were discussed relative to qualitatively and quantitatively based explanations of age differences in memory.
