%X One hundred volunteer retirees were stratified by gender and randomly assigned to temporal or spatial experiments desiped to correlate past and present activity level with elder infor- matlon processin abilities. Nine measures of activity level were derived from selfreports of behavior before and after retirement. Controlled information processing measures were derived from a series of motor performance tasks using a validated model of analy- sis that separates central from peripheral control and that assesses baseline, learning, and retention abilities. Results suggested that the retention of controlled information processing abilities are redict- ably related to past and present activity level, but only w R en the act~vities are maintained into older age or begun and participated in during older age.<p />
