Transfer of the Avoidance Function in Equivalence Classes Using Loss of Points as the Aversive Stimulus

The present study evaluated whether transfer of the avoidance response in equivalence classes is produced using the loss of points as the aversive stimulus. In the first phase of the experiment, 11 participants established two equivalence classes with four visual abstract stimuli each (Class 1: A1, B1, C1, D1; Class 2: A2, B2, C2, D2). In the second phase of the experiment, only one visual stimulus (B1) was paired with point loss. An avoidance response to B1 was then established. In the third phase of the experiment, the other stimuli were presented in a transfer of avoidance test. An avoidance response was established for all 11 participants, and the transfer of avoidance occurred for 10 of them. These results indicate that point loss can function as an effective aversive stimulus to maintain an avoidance response and produce transfer of the avoidance function in equivalence classes. The use of point loss may be a valuable tool in human operant research to substitute for other aversive stimuli with undesirable side effects.
