The manner in which the process of aging affects human information processing is of considerable theoretical and practical interest. Performance measures reflecting psychological processes, such as short-term memory organization, utility of redundancy, and- motor performance, change with age (see, for example, Talland, 1968; Craik, 1977; Rabbitt, 1977; Welford, 1977). The mechanisms underlying these changes and their basis in the physiology of the aging nervous system are of great interest. It is often not clear, however, how changes in the psychological processes are related to the neural concomitants of senescence. There are changes in the brain associated with aging, such as atrophy or the accumulation of certain chemical substances (see, for example, Bondareff, 1977). Information is needed which will help relate complex cognitive behavior to such measurable attributes of neural processes.
