A validation study of the Ambinder Auditory Perception Test.
The purpose of this study was the initiation of the validation procedures for the Auditory Perception Test (APT), developed in the late 1960s by Walter Ambinder, a clinical psychologist at Wayne State University. Two studies concerning the APT preceded the present one. Armstrong (1974) undertook the first phase of standardization by completing a reliability study and a factor analysis on the test. The second phase was accomplished by Adams (1975) , who revised the APT and ascertained its reliability. The Adams Revised Auditory Perception Test was not available for the present study, and therefore, this validation was concerned with the original Ambinder APT.
