Final answer:
Positive reinforcement is the behavioral change strategy that presents an attractive outcome after a desired behavior, to increase the likelihood of that behavior being repeated.
Step-by-step explanation:
The strategy for behavioral change that consists of presenting someone with an attractive outcome following a desired behavior is known as positive reinforcement. In positive reinforcement, a desirable stimulus is added after the desired behavior has been performed, indicating the behavior is good and should be repeated. This form of operant conditioning, which is based on the work of B. F. Skinner, aims to increase the likelihood of the desired behavior occurring in the future.
