Which best describes shaping through successive approximations?

• A. Behaviors can be shaped through successive approximations, reinforcing responses similar to the desired behavior
• B. Shaping uses random reinforcement
• C. Shaping reinforces only the exact target response
• D. Shaping requires punishment for incorrect approximations

Answer: (A)

Shaping through successive approximations is about reinforcing behaviors that move someone toward a desired end behavior. You start with a behavior the learner already shows or can do, and then you reinforce that, gradually requiring steps that are closer to the target. Each small, near-target response earns reinforcement, so the learner’s behavior climbs incrementally toward the final goal. This approach relies on reinforcement of approximations, not randomness, punishment, or only waiting for the exact final response. For example, teaching a dog to fetch might begin with rewarding looking at the ball, then picking it up, then bringing it closer, and finally bringing it all the way back. This makes the gradual progress toward the target clear and achievable.
