Acquisition of prototype-based information about social groups in adulthood.
Two experiments examined adult age differences in the ability to acquire prototype-based information about a fictitious social group. Young and older adults were presented with 60 descriptions of people who varied in their similarity to a prototypical group member along 12 (Experiment 1) or 10 (Experiment 2) feature dimensions. The prototype represented either an arbitrary combination of features or a coherent set of features based on evaluative content. Younger adults generally performed better than the older adults in learning the arbitrary prototype, whereas age differences were absent or in favor of the older adults when the prototype consisted of evaluatively consistent features. The authors argue that the results can be explained by the age-related variations in the reliance on automatic processing mechanisms and the congruence of these processes with the demands of the task across prototype conditions.
