What is successive approximation?

What is successive approximation?

• A. It's when MWDs are taught behaviors by rewarding responses that are progressively more like the desired target response.
• B. It describes the plan for selecting which behaviors to reinforce.
• C. It refers to randomizing the timing of rewards.
• D. It is the process of punishing incorrect responses to shape behavior.

Answer: (A)

Successive approximation, often called shaping, is a training method where you reinforce behaviors that become gradually closer to the final target behavior. In MWD training you start with an easy, observable action the dog can perform and reinforce it, then require a closer version of the target before giving reinforcement, and continue this step-by-step progression until the full behavior is shown reliably. This approach builds complex skills by chaining small, achievable steps into the desired response, rather than waiting for one perfect action. For example, in scent-detection work you might first reward any sniff near the target, then reward a closer approach and a specific alert near the source, and so on, until the dog consistently performs the full indication. The other options describe reinforcement planning, alternating timing of rewards, or punishment, none of which capture the gradual, closest-to-target reinforcement process that shaping uses.
