Discriminative stimulus context in matching-to-sample of Japanese monkeys

Transfer of matching-to-sample behavior by Japanese monkeys was investigated in a freeoperant situation in order to reexamine stimulus control of the behavior. Following the author's earlier study (Kojima, 1979), the same two monkeys were retrained on a pattern matching-to-sample and shifted to three successive transfer situations. For a proper evaluation of transfer effects, an intermittent reinforcement schedule (VI 60s) for a correct matching trial maintained the rate of reinforcement relatively low and kept it almost unchanged in the transfer situations. The results showed that both monkeys attained successful tranfser of matching behavior in the second (intradimensional) transfer situation, but exhibited performance disruption in the third (extradimensional) transfer situation using color stimuli. The present findings suggested that they are capable of learning a concept of “sameness”, but with little generality
