Using a modified discrimination task, the testing system draws on a pool of 130 items spanning a broad range of difficulty to estimate an examinee{\textquoteright}s location along an underlying continuum of speech processing ability, yet does not require the examinee to possess a high level of English language proficiency. The system is driven by a mathematical measurement model which selects only test items which are appropriate in difficulty level for a given examinee, thereby individualizing the testing experience. Test items were administered to a sample of young deaf adults, and the adaptive testing system evaluated in terms of respondents{\textquoteright} sensory and perceptual capabilities, acoustic and phonetic dimensions of speech, and theories of speech perception. Data obtained in this study support the validity, reliability, and efficiency of this test as a measure of speech processing ability.}, keywords = {*Diagnosis, Computer-Assisted, *Speech Discrimination Tests, *Speech Perception, Adolescent, Adult, Audiometry, Pure-Tone, Human, Middle Age, Psychometrics, Reproducibility of Results}, author = {Bochner, J. and Garrison, W. and Palmer, L. and MacKenzie, D. and Braveman, A.} }
