Feedback effects on the performance and self-reinforcing behavior of elderly and young adult women.

A total of 64 college-aged and elderly women participated in an experimental study of the effects of noncontingent positive feedback on simple speeded performance, performance self-evaluations, and self-reinforcing behavior (i.e., the number of S&H Green Stamps taken following feedback). Younger women self-reinforced more and held higher self-evaluations of their performance than elderly women. The treatment produced increases in all three dependent measures, and greater increases in self-reinforcing behaviors and self-evaluations were demonstrated for the elderly than for the younger women. The results are discussed in terms of age-associated differences in the susceptibility to external feedback.
