Final answer:
The psychological perspective displayed by Rob's method of training his dog is the behavioral perspective, which uses operant conditioning to modify behavior through rewards and punishments.
Step-by-step explanation:
Rob's approach to teaching his dog to roll over on command by rewarding the dog with food is similar to the behavioral psychological perspective. The correct answer to the question is c. Behavioral.
The behavioral perspective, which encompasses both classical and operant conditioning, fits Rob's method of training his dog. Operant conditioning, a concept introduced by B.F. Skinner, involves modifying behavior through reinforcements and punishments. When the dog performs the desired action, such as rolling over, and is rewarded with food, it experiences positive reinforcement. Over time, the dog learns to associate the action with the reward and is more likely to repeat the behavior. This type of learning is emphasized in the behavioral perspective of psychology, which focuses on studying observable behaviors and how they are shaped or influenced by the environment.
