Integration or ‘Wholeness 1 is the main assumption of Behaviouralism According to Behaviouralism, man is a social animal. His political behaviour is affected by many non – political elements like social economical, religious and cultural factors. Thus, it is not possible to study human behaviour in small parts. In such situation, it become compulsory to study political activities and behaviour in relation to the other activities of the society.
Behaviouralism lays stress on inter-disciplinary study by connecting Political Science and other social sciences. Researchers of Political Science should use the researches and achievements of other social sciences. Thus, behaviourialistic thinkers believe that knowledge of different social sciences should be integrated.
