Perception of Complex Auditory Patterns.
Abstract
This project continued and extended a series of experiments on the discrimination and identification of complex auditory patterns. The general purpose of this work is to determine the limits of human listeners' abilities to extract information from complex sounds including, but not limited to, those with temporal and spectral properties approximating speech. Experiments used criterion-controlled psychophysical methods in which listeners were trained until approaching asymptotic performance in various discrimination and identification tasks. Advances were made in the following areas: (A) the spectral and temporal range of selective auditory attention; (b) the time course of auditory perceptual learning; (c) informational limits on pattern discrimination; (d) listeners' abilities to learn to attend to multi-tone targets within longer patterns; (e) individual differences in auditory sensitivity, and (f) the perception of spectrally complex sound, including speech and non-speech sounds.
