When is reinforcement typically delivered in a backward chaining procedure?

In a backward chaining procedure, reinforcement is provided immediately after the learner completes the final behavior in the chain. This method focuses on teaching the last behavior in a sequence first, so that the learner experiences success and reinforcement early in the process. By reinforcing the final behavior right away, the learner can better understand the relationship between their actions and the outcome, which helps in building the entire chain of behaviors.

This immediate reinforcement after the final behavior creates a strong connection, encouraging the learner to engage in the previously learned behavior that leads to this final step. Over time, as more behaviors are added to the chain, the learner becomes proficient in performing the entire sequence, ultimately leading to the successful completion of all steps of the task.
