Successive Approximation is defined as which of the following?

• A. Aversive punishment
• B. Increasingly or altering a behavior incrementally by repeatedly changing the environment to amplify or extend the behavior
• C. Observing without intervention
• D. Complete behavior capture at once

Answer: (B)

Shaping a behavior by reinforcing successive approximations means you reward small steps that progressively resemble the final target, and you tighten or adjust the criteria as the animal improves. Instead of waiting for one perfect display, you celebrate the near-misses that move closer to the goal and gradually require more precise or extended responses. This often involves gently guiding the animal through a sequence of tiny steps and changing what you reinforce as each step becomes reliable. For example, teaching a dog to roll over can start with a reward for lying down, then for turning the head to the side, then for rolling onto the back, and finally for completing the full roll. Each successful step reinforces progress, building the full behavior incrementally rather than expecting it all at once. This is different from punishment-based methods, which aim to reduce undesired behavior, or from passive observation without intervention, or from demanding an entire complex behavior in a single attempt.
