ABSTRACT
There appear to be three uses of the term ‘interaction’ in social and clinical science: (a) the study of how relatively uncorrelated variables act together to produce a final outcome;1 (6) the study of how correlated variables act together to produce a final outcome; (c) the study of the social relationships of two or more people, and of the influence of these relationships on their behaviour and attitudes. This last approach is exemplified by Rose’s monograph (1962), Human Behaviour and Social Process-an Interactionist Approach.
