Long-term effects of fluid ability training in old-old age.

This study examined the effects of multiple phases of cognitive training on older adults' intellectual performance over a 7-year period as Ss advanced from young-old to old-old age. The study involved a pretest-posttest/no-treatment control-group design. At each of 3 training phases, conducted in 1979, 1981, and 1986, Ss received 5 training sessions on the fluid ability of figural relations. Participants (N=38) had a mean age of 69 years (range = 63-80) at the onset of the study.
