A case of special ability with below average intelligence

Abstract

A man who displayed an extraordinary memory for numbers has an I. Q. of 92.6 on the basis of his performance on the Terman adult test. An analysis of the individual tests shows a "high-power visual with little evidence of average auditory memory, and little capacity to handle problems that involve reasoning."
