Abstract: Behaviourism stands for a group of theories, which define consciousness in terms of bodily behaviour which is observable to others. Behaviour is easily observed and verifiable by others. The intension of this theory is emphasizes on behaviour and to demystify mind. This theory out rightly denies the existence of mind as an independent substance and supposes that behaviour is out and out determined by the physical conditions of the body and its interaction with the environment. Moreover, this theory does not accept any unobservable stimuli rather it focuses solely on observable stimuli, responses and its consequences.Now in this paper I will delineate the main theme of Behaviourism including its different types emphasising my discussion on Analytical Behaviourism. Finally I will highlight the drawbacks of Analytical Behaviourism and hoe does this theory paves the development of Identity Theory of Mind.
