Show Summary Details


This chapter reports the results of the cognitive intervention studies and their long-term follow-up and replication with new cohorts, as part of the Seattle Longitudinal Study. These studies lead to the conclusion that, for many persons, cognitive decline in old age may be a function of disuse rather than deterioration of the physiological substrates of cognitive behavior. A brief five-hour training program on the abilities of Inductive Reasoning and Spatial Orientation involving individual tutorials was designed to improve the performance of participants above the age of sixty-four years. Participants were assigned either to training in the ability on which they had declined or randomly to one of the two training conditions if they had declined or remained stable on both abilities.
