What are the different levels of reinforcement?

The different levels of reinforcement are indeed best represented by the concepts of extinction, continuous reinforcement, and intermittent reinforcement.

Continuous reinforcement refers to a schedule in which every instance of a desired behavior is reinforced. This type of reinforcement is effective for establishing a new behavior, as it provides immediate feedback and encourages the behavior to occur consistently.

Intermittent reinforcement, on the other hand, involves providing reinforcement only after certain responses are made, not every single time the desired behavior occurs. This can take various forms, such as fixed-ratio or variable-ratio schedules. Intermittent reinforcement is known for creating stronger and more durable behaviors than continuous reinforcement over time, as it can lead to expectations of reward and increase persistence in the absence of immediate feedback.

Extinction pertains to the process where reinforcement is no longer provided for a previously reinforced behavior, leading to a decline in that behavior's occurrence. Understanding extinction is crucial in behavioral modification, as it highlights the importance of consistency in reinforcement.

The other presented options do not accurately capture the established categories used in behavioral psychology. Hence, the combination of extinction, continuous reinforcement, and intermittent reinforcement effectively covers the essential levels of reinforcement.
