Abstract: Age differences in attention seem salient to age-related declines in declarative secondary memory. Ninety community-dwelling adults (ages 30-80+) completed a neuropsychological battery that included Logical Memory, Cowboy Story, Visual Reproductions, and Extended Complex Figure Test. Using a subtractive regression procedure to measure attentional contributions to retrieval, a negative relationship between age and retrieval efficiency emerged on all measures (p less than or equal to .5). The sizes of the age effects decreased as visual-spatial demands increased, and the portion of the age effect that was explained by attention also decreased with increasing visual-spatial involvement. Auditory-verbal retrieval appears to require more attention than visual-spatial retrieval, rendering the former more vulnerable to aging.
