Tests were administered to 209 educable mentally handicapped children (mean age 10.8, mean IQ 77) to determine factors related to speech hearing. Results indicated that mental age, intelligence quotient, physiological age, institutionalization, and organic bases for retardation were not significantly related either to speech reception threshold or to speech discrimination test scores. However, chronological age was related to test performance. Also, the threshold and the discrimination by the Identification of Pictures tests were found both reliable and useful with the educable retarded subjects. (Author/JD)
