The processing of frequency of occurrence information by adults.

Three groups of adults (mean ages 22, 43, and 68 years) listened to a list containing 30 words that were repeated from zero to seven times each. The subjects were then tested for their sensitivity to differences in frequency of occurrence. All groups were found to be equally sensitive to frequency information. Prior knowledge about the exact nature of the forthcoming test did not affect performance. These results are interpreted in light of a theory that suggests that performance is determined by at least two factors: the cognitive capacity that an individual has available, and the capacity demands imposed by the task.

Timing, instructions, and inhibitory control: some missing factors in the age and memory debate.

In response to Luszcz and Bryan, we point to three omitted factors that have been found to influence the presence and size of age differences in memory tasks and that, as such, have important implications for resolving theoretical questions about aging and memory. These include: (1) age differences in circadian rhythms and testing time effects that are associated with such differences; (2) instructions that may have a particularly disruptive effect on older adults, and (3) inhibitory control differences that have an age-related impact on both estimates of working memory span and on performance in multitask studies.
