A short form of the Speech-Sounds Perception Test based on the last three series is presented. For the total sample of 632 the KR-20 reliability was .84. An age- and education-corrected standardized score formula is provided. Reliability coefficients and descriptive statistics are presented for three groups, 107 normal, 150 diffusely brain-damaged, and 310 undiagnosed patients sent for assessment plus 65 volunteers for the normal group.
