The Progressive Matrices and Mill Hill Vocabulary Scale in Western Societies

In this paper, some recently obtained results demonstrating the stability of scores on the Standard Progressive Matrices Test when applied to different sub-groups within the UK and in other Western societies, and variance over time, will be summarised. This material has now been published in full in a Research Supplement to the Test Manual (Raven, 1982). It is hoped to produce another Supplement dealing with the uses which have been made of the Progressive Matrices in third world countries, the modifications which have been made to take account of local circumstances, and the results and experience which have been gained. It would be most helpful if those who have relevant experience would contact the author.
