HC Deb 22 May 1957 vol 570 cc86-7W
Mr. Dodds

asked the Minister of Health, as representing the Lord President of the Council, what was the last occasion on which the Medical Research Council sampled young adult high-grade patients in respect to the level of intelligence, and with what result; and when it is proposed that the next sampling shall take place.

Mr. Vosper:

As part of an investigation concerned with the training and rehabilitation of high-grade mentally defective patients, members of the staff of the Medical Research Council's Social Psychiatry Research Unit carried out tests to estimate the degree of intelligence of young male patients admitted to one institution during 1949 and 1950. The average intelligence quotient as judged by several different tests was found to be about 70. The results of this study have been published and it is not proposed to repeat the work.
