Specific Changes in Cognition with Aging

In a recent review on cognitive changes in aging, Bieliauskas (2001) noted that the "body of knowledge in cognition and aging is growing exponentially" and at times may seem confusing (page 104). However, some general trends from the literature do seem to be emerging. First, while there is a general trend for cognitive performance to decline with aging, the rate of decline can vary considerably among individuals (Bieliauskas, 2001; Benton et al., 1981). Second, not all cognitive functions decline at the same rate or to the same degree. In general, the changes in cognition and memory are more in terms of speed than power.
