What is shaping in operant conditioning?

Shaping in operant conditioning refers to the process of reinforcing successive approximations of a desired behavior until the target behavior is achieved. This involves gradually guiding an individual towards the desired behavior by rewarding them for making progress, no matter how small. For example, if a trainer wants a dog to learn to roll over, they might first reward the dog for lying down, then for turning its head, followed by rolling slightly to the side, and finally for completing the full roll. Each step towards the final behavior is reinforced, which motivates the subject to try more complex actions.

This method is particularly effective because it allows the instructor to break down complex behaviors into smaller, more manageable parts, facilitating learning even for behaviors that may be difficult to achieve all at once. Each reinforcement further encourages the individual to approach the final stage of the desired behavior, capitalizing on the natural learning process through positive reinforcement.
