Effects of Reinforcement Condition upon Long-Term Retention of Retarded

4 groups of educable, teenage retardates learned a motor task, each under a different token contingency condition. 14 days later, Ss were tested on two retention measures to determine relationship between reinforcement condition and long-term memory. The recall measure indicated that a response-cost condition resulted in higher recall than the reward, combination cost/reward or non-token controls, however, a savings score analysis did not demonstrate treatment differences.
