Facilitated Learning

An experiment designed to specify the process similarities of information feedback and reinforcement and to note the interaction of 2 major feedback variables on a simple positioning task. 80 students were randomly divided into 4 groups receiving either 25, 50, 75, or 100% schedules of feedback, analogous to fixed-ratio schedules of reinforcement. The 4 groups were further divided into 2 subgroups that differed in terms of specificity of feedback. Results indicated that when all Ss were provided the same number of feedbacks, the groups did not differ during acquisition. Groups with partial information feedback demonstrated greater resistance to extinction. The coarse-scale treatment facilitated learning but had no effect during extinction. There was no interaction between frequency and specificity of information.

First Contact

In this article, we present a method for illustrating the continuity of behavior during schedules of reinforcement. Students experienced either a fixed-interval 15-sec schedule in which the first contact after 15 sec of a cursor on a computer screen with a 0.7-cm diameter virtual (invisible) target resulted in reinforcement (a beep) or a fixed-ratio 5 schedule in which every 5th contact with the target produced the reinforcer. In addition to illustrating the continuity of behavior, this method provides a means of exposing students to concepts and methods such as the acquisition of operant behavior, the assignment-of-credit problem, the organization of behavior across time, and the analysis of single-subject data.
