The Biological perspective focuses on three areas which are Comparative, Physiology and Inherent. The Comparative method can be used to compare two different types of animal or plants. The Physiology method goes more in depth into how the anatomy can function. The Inherent method is who and what we had received to be who we are.

Pavlov had a break through from the fact that the dog had learned that the bell meant food, which reversed after a while when no food had been presented.
