The ADD Test--Auditory Discrimination in Depth.
Lindamood, Charles H.
The ADD (Auditory Discrimination in Depth) Test measures the auditory perceptions basic to grasping the logic of the English writing and reading system. If the level of a subject's auditory perception--his ability to discriminate the phonemes of English and his ability to code phonemic sequences in both non-syllabic and syllabic units--can be determined, it can be estimated how much developmental work is going to be needed before the writing and reading task will become comprehensible to him. The ADD Test gives both diagnostic and prognostic information in this respect. This test requires the subject to manipulate colored blocks to indicate his perception of the relationships of sounds in oral patterns. The three categories involved are designed to check the ability to (1) discriminate isolated phonemes in sequence; (2) perceive phonemic relationships in a simple, protected syllable; and (3) perceive phonemic relationships in complex syllables. Informal norms suggest that if auditory perceptual judgment is functioning, four-year-olds can handle Category I, first- and second -graders can handle Categories II and III. Difficulty with Category I after five or six years of age is uncommon, but even some adults cannot handle Categories II and III. This deficiency has been reflected in almost every instance in poor word attack in reading and poor spelling skills. (See related document ED 028 430.) (AMM)
