Abstract
On occasion, listeners are encountered in psychoacoustic studies who have audiometrically normal hearing but seem unable to perform certain auditory tasks at the same level as other people. In addition, clinical research has related individual differences in auditory processing to some disorders of communication, cognition, and learning. However, it is difficult to label performance on many auditory tasks as “impaired,” in the absence of a normative data base. To this end, an auditory test battery is being developed. The first version includes masked and quiet thresholds; intensity, frequency, and temporal discrimination; and discrimination of tonal sequences. The components of the test battery were chosen to sample the auditory capabilities that underlie complex auditory processing, including speech perception. Each test is continued until asymptotic performance is observed in an adaptive psychophysical procedure. Although most audiometrically normal listeners perform very much like one another on all of the subtests, a few individuals show patterns of significantly deviant (<2σ) performance for specific clusters of subtests, such as those requiring frequency resolution or those requiring temporal discrimination.
