7 getting a new behavior to occur with shaping. Positive reinforcement could be used to increase the frequency of a behavior provided that the behaviour occurred occasionally. It is not possible to increase its frequency simply by waiting until it occurs and then reinforcing it. However, a procedure called shaping can be used to establish a behavior that the individual never performs. The behaviour modifier begins by reinforcing a response that occurs with a frequency greater than zero and that at least remotely resembles the final target behaviour. Frank for example, was first reinforced for walking once around his house b/c this behaviour occurred occasionally and remotely approximated his nonexistent behaviour of jogging a quarter of a mile. When this initial response is occurring at a high frequency, the behaviour modifier stops reinforcing it and begins reinforcing slightly closer approximation of the final target behaviour.
