Final answer:
The statement is false; while contrived reinforcement can aid in backward chaining, it is not always necessary as natural reinforcements or the task itself may serve as sufficient reinforcement.
Step-by-step explanation:
The statement 'Contrived Reinforcement is always necessary for Backward Chaining' is false. Backward chaining is a teaching technique often used in applied behavior analysis where a complex task is broken down into simpler steps, and the last step is taught first. Once the last step is mastered, the second-to-last step is taught, and so on, until the entire sequence is learned. While contrived reinforcement, which refers to rewards provided by the teacher that are not naturally occurring for the behavior, can be helpful in backward chaining, it is not always necessary. Natural reinforcements, which occur directly as a result of the behavior, can also be effective, and in some cases, the task itself may be reinforcing enough to encourage learning.
