Thirty-one male patients, aged between 16 and 48, were given both the full scale W.A.I.S. and the new revision of the Stanford-Binet (L-M). The correlation between them was high, but the Binet gave quotients which were significantly different from the Wechsler I.Q.s in terms of score level. The results suggested that a W.A.I.S.I.Q. of 80 was a more realistic cut-off point for subnormality if the tests scores were to bear a closer relationship to medical and legal diagnoses of subnormality.
