It has been reported that some persons can discriminate non-visually among stimulus objects usually requiring visual cues. The majority of investigations seek merely to support or negate such reported aptitudes. Little interest has been directed toward learning such a skill. The present study was conducted in order to evaluate the effects of reinforcement versus non-reinforcement upon hypothesized discriminative learning of black-white and red-blue stimuli. A total of sixteen subjects participated in this experiment. Each subject was presented eight blocks of sixteen trials each. Four blocks were presented on each of two different days. The blocks of trials were broken down into two blocks with black-white stimulus plates and two blocks with red-blue stimulus plates--all presented under plastic to eliminate textural cues. Each subject was presented a total of one hundred twenty-eight trials. It was found that verbal reinforcement, as compared to non-reinforcement did not significantly influence correct color choices and thus the hypothesis that discriminative learning would take place was not supported.
