The categorisation process in intergroup relations

In the first two parts of the paper a distinction is made between a ?conflict or convergence of interests' approach (Sherif) and a ?categorisation' approach (Tajfel) in the area of the experimental study of intergroup relations. Some recent experimental findings are mentioned, and a theoretical development of the categorisation approach is proposed. In the third part a new experiment illustrating the relevance of the categorisation approach is described.
