Defense Mechanism is one explanation of Psychological Therianthropy.

It should be noted that some psychologists consider defense mechanisms and coping mechanisms to be different. The difference is that a defense mechanism is considered to be subconscious. Whereas, a person can consciously choose between different coping strategies and find which strategy works best.[1]
