Answer:
The answer is: C. Behavioristic.
Explanation:
There are multiple theories that try to explain personality formation and several psychological disorders from the psychological perspective, as opposed to the medical perspective for example. The behavioristic perspective draws upon Skinner's findings. It claims that personality and even mental health disorders are a result of people's conscious experiences with their environment, and the reinforcements and punishement they experienced while growing up. Our personality is conditioned by the environment, and in order to modify it, the person must remove the reinforcements and stimulus that are present in it.
Therefore, if Dr. Ferris explains personality and psychological disorders in terms of reinforcement or punishment, he gives more importance to the behaviorist perspective.
