Reducing the occurrence of mouthing and jumping in a dog through conditional discrimination training

Many approaches for reducing unwanted behavior use punishment, extinction, or noncontingent reinforcement. Other methods focus on teaching and reinforcing alternative behaviors that can replace the unwanted behavior. Another strategy can be to change the stimulus control of the unwanted behavior. The present study investigated if conditional discrimination training using positive reinforcement could reduce undesirable behaviors in a pet dog. After conditional discrimination training, two unwanted behaviors (jumping and mouthing) occurred reliably in the presence of new discriminative stimuli, while other behaviors occurred in the presence of the discriminative stimuli that had previously produced these unwanted behaviors. This experiment demonstrates that conditional discrimination training can be an effective way to control the frequency of an unwanted behavior by controlling the frequency of the presentation of a discriminative stimulus.
