This research aims at the character and behavior analysis of Heathcliff in Emily Bronte’s novel Wuthering Heights. The researcher attempts to represent the behavior of Heathcliff in the light of Stimulus-Response theory in order to justify his strange, harsh and unusual behavior. The researcher applies the stimulus-response theory proposed by a renowned American Psychologist, John B.Watson, who asserts that the basic factor behind the formation of human behavior is Environment, and that human behavior is conditioned through the stimulus-response association, thus human behavior is a response to a stimulus. The research follows the descriptive method of analysis and close text-reading approach. The study shows that how the behavior of Heathcliff is shaped taking influence from his surroundings, people and his bitter experiences. The study proves that his harsh and bizarre nature is the product of his environment and his behavior being patronized through a particular stimulus -response bond.
