In two experiments the relation between past contact, stereotypic associati
ve strength, and stereotype activation effects on memory performance was in
vestigated. It was hypothesized that, for some stereotypes, contact can lea
d to the development of stronger stereotypical associations. Associative st
rength, in turn, was expected to determine stereotype activation effects on
behavior tin this case, memory performance). In Experiment 1, it was shown
that people who reported to have had much previous contact with elderly pe
ople performed worse on a memory (free recall) test after being primed with
the stereotype of the elderly. People who reported to have had little prev
ious contact did not show any effects of priming. In Experiment 2, we confi
rmed that this effect is mediated by associative strength. People who repor
ted to have had a lot of contact with the elderly had developed an associat
ion between the category elderly and the attribute "forgetfulness." The str
ength of this association, in turn, predicted the degree of memory impairme
nt after activation of the category elderly. (C) 2000 Academic Press.
