Abstract
The experiment reported here represents a partial replication of an experiment by Newman, Buffington, and Hemmes (in press) and analyzes responding in college students as a function of three different schedules of reinforcement (FR 1, FR 2, FR 3) and either verbal discriminative stimuli (instructions) or nonverbal discriminative stimuli (different colored cards). All consequences (tokens) were based on behavior consistent either with the verbal discriminative stimulus (SD) or with the nonverbal SD. The schedule of reinforcement varied across subjects, and accuracy of the verbal and nonverbal SDs varied across phases from. Results showed that the behavior of all continuous reinforcement (FR 1) subjects was sensitive to the accuracy of the verbal SDs, but the behavior of subjects in the nonverbal SD conditions showed more sensitivity than the behavior of subjects in verbal conditions under intermittent schedules (FR 2 and FR 3). These finding suggest that the behavior of subjects in experiments where instructions are sometimes pitted against actual contingencies of reinforcement is a function not only of the instruction, but also of the type of reinforcement schedule used.
