The effects of age-stereotype priming on the memory performance of older adults.

The effects of age-stereotype priming on the memory performance of older adults were investigated through a conceptual replication and extension of Levy's (1996. Journal of Personality and Social Psychology, 71, 1092-1107) study. Sixty young and 60 older adults were subliminally primed with a positive age stereotype, a negative age stereotype, or neutral primes. Memory performance on two tasks (a photo recall task and a dot location task) was measured before and after the priming intervention. Although the study does not provide unequivocal support for Levy's (1996) findings, results did show that priming a negative age stereotype undermined memory performance for a small sample of older adults who were "unaware" of the primes. However, contrary to Levy's findings, priming a positive age stereotype did not increase older adults' memory performance. There were no significant effects of priming positive or negative age stereotypes on the memory performance of young adults.

Aging, encoding fluency, and metacognitive monitoring.

Encoding fluency (how rapidly one generates a mediator for a new association) may be a cue used to judge one's own learning. To evaluate age differences in utilization of this cue, older and younger adults were instructed to use interactive imagery to study paired associates, pressing a button to indicate when an image had been formed for a given pair. A judgment of learning (JOL) was also made immediately after each pair had been studied. Hence, at least two cues pertaining to encoding fluency-whether an image had been formed (a diagnostic cue) and the latency of formation (a nondiagnostic one)-were available when making JOLs. Age equivalence was found in JOL accuracy, and JOLs for both age groups were positively related to imagery formation and were negatively related to the latency of image formation. Moreover, subjectively judged latency correlated higher with JOLs than actual (objective) latency, supporting the hypothesis that perceived fluency is a cue used in constructing JOLs.
