This volume contains a presentation of the Bellevue scale of adult intelligence. Part I discusses the nature and classification of intelligence and the concepts of mental age, the intelligence quotient and mental deficiency and indicates the need for an adult scale of intelligence standardized with adults, thus eliminating the use of children's scales for adults. Part II describes the Bellevue intelligence scale, the selection of the tests that comprise it and their standardization. Part III is a manual of instructions for giving and scoring the tests. This is a clear presentation of problems of measurement of intelligence, and provides a scale which is simple to give and is reliable, being based on a careful statistical analysis of the responses of more than 2,000 clinic subjects.
