Abstract: The effects of continuous and intermittent reinforcement on the maintenance of accuracy in extinction of a discrimination taught with errorless discrimination procedures in trial conditions were investigated in a functional analysis of responding by four Black kindergarten boys on alphabet letter discriminations. This study was based on an experiment by Terrace (1970) in which he found increased error responses in extinction by subjects who had been trained with errorless procedures and continuous reinforcement in trial conditions. A within-subject design was employed in the present study. The experimenter taught subjects individually in daily one-to-one sessions over a six-week period. Subjects were taught to name one letter in each of two letter pairs during an acquisition phase. Letter pairs were “b-d” and “p-r”. Letters were printed individually on cards which were shown to subjects in random sequence in timed sessions by means of a handmade apparatus. During the first training session, the letter not to be named was initially different from the one to be named in size, shade, and time of exposure. It was gradually changed (faded) on successive trials throughout the session until it was different from the other only in its distinctive shape. Marbles redeemable for pennies were delivered for correct responses. An error occurred if a subject made any naming response to the inappropriate letter. One letter pair was maintained on a schedule of continuous reinforcement and the other was gradually switched to an intermittent schedule during a maintenance phase. During extinction, reinforcement was withheld. The basic datum in this study was frequency of responding. Frequencies for correct responses and errors were recorded daily on the Standard Behavior Chart. Celerations, or trend lines reflecting changes in frequency over time, were calculated from frequencies for correct responses and errors in each phase. Overall accuracy was obtained in each phase by an improvement index, an expression of the ratio of celerations for correct responses and errors. Grouped data was expressed by geometric means of celebrations and improvement indices for the four subjects. Results of this study were not consistent with those of Terrace’s (1970) experiment, and failed to reveal any noticeable difference in the degree to which accuracy of discrimination was maintained in extinction following errorless discrimination training with continuous and intermittent reinforcement for the four subjects used in this study. Frequency of correct responding was only slightly lower during extinction when compared to the maintenance phase for both schedules. Comparison of error trends between the maintenance and extinction phases revealed an increase in errors during the latter, for both reinforcement conditions, with the values of the trends identical. Subjects displayed much “emotional” or “frustration” behavior during extinction. It was suggested that the results of this study demonstrated the efficacy of errorless procedures in discrimination training as well as the pitfalls of a priori assumptions concerning the relevancy of experimenter-selected methods and materials. The results did not justify any statement relative to the superiority of one reinforcement schedule over the other in errorless discrimination training in trial procedures.
