The effect of response force on avoidance rate.
In a Sidman-avoidance schedule of counter losses for two human subjects, the loss-to-loss and response-to-loss intervals were 20 sec. The avoidance response was a vocal response that was louder than a minimum vocal requirement. This requirement was set at 80 db, 95 db, or 110 db. In addition to vocal responses meeting the minimum requirement, all responses exceeding a threshold of 75 db or louder were recorded. The rate of both above-threshold and avoidance responses decreased as the response-force requirement increased. Thus, high response-force requirements produced an effect on avoidance responding similar to its effect on positively reinforced responding.
