Modification of concept identification performance in older adults

A sequential training procedure combining operant and cumulative learning hierarchy principles was found effective in reducing the decrement in concept identification performance typically observed in older adults. 20 male and 20 female Ss aged 63-83 yrs were given a pretest and posttest, each involving a 3-category unidimensional concept identification problem. The training and reinforced-training Ss were given 3 training sessions between pretest and posttest. Training involved a programmed learning sequence designed to facilitate the development of an effective solution strategy. Control Ss were given only the pretest and posttest, while practice Ss were given 3 additional practice sessions. Substantial improvement was found in both the training and reinforced training groups, but only slight improvement obtained in the practice and control groups. Results are consistent with recent conceptions of cognitive and intellectual development in the older adults in which performance deficits are largely attributed to experiential factors. (15 ref)
