Which statement about chaining is accurate?

The accurate statement about chaining is that each behavior must serve a purpose in the chain. In the context of chaining, every individual behavior contributes to completing the overall task or skill being taught. This means each step in the chain is interdependent and helps facilitate the subsequent step, leading to the final desired outcome.

For example, when teaching someone to make a sandwich, each action—gathering ingredients, spreading condiments, layering items—plays a vital role in achieving the final product. If any part of the process were omitted or not performed correctly, the entire chain could break down, demonstrating the necessity of purposeful contributions from each behavior.

While other options present misconceptions about chaining: some suggest all behaviors are taught simultaneously, thereby disregarding the sequential nature of chaining; others imply that chaining's focus is limited to reinforcing just the final behavior, overlooking the importance of each step in reinforcing the entire process; and yet another option indicates that chaining lacks an order, which contradicts its fundamental design of following a specific sequence of actions.
