AnnotationIt is argued that inhibition is an important contributor to age-related performance decrements in cognition. 100 older American volunteers (50 men and 50 women, mean age 72.74) were assessed for processing speed. Findings demonstrated that inhibitory processes continued to decline with advancing age within the older sample. In addition, the role of inhibition in age-related performance deficits on a verbal list learning measures and an attention measure was examined. Hierarchical regression analyses showed that inhibition accounted for a significant proportion of the age-related variance on two cognitive measures, whereas measures of reading speed accounted for a smaller proportion of the variance.
