Professors from the University of California at Berkeley were administered a 90-min test battery of cognitive performance that included measures of reaction time, paired-associate learning, working memory, and prose recall Age effects among the professors were observed on tests of reaction time, paired-associate memory, and some aspects of working memory Age effects were not observed on measures of proactive interference and prose recall, though age-related declines are generally observed in standard groups of elderly individuals The findings suggest that age-related decrements in certain cognitive functions may be mitigated in intelligent, cognitively active individuals
