 The three approaches introduced in 1970’s in human geography are :

(ii)Behavioural Approach: The limitations placed by positivism led to reactions against it. This ‘approach’ is mainy borrowed from psychology. The Behavioural approach was an antithesis of positivism in which the cognitive power of human beings was emphasised. Woolpert and Oloson are the staunch supporters of Behavioural Approach.
