Additivity and Auditory Pattern Analysis

Abstract

Human discrimination of complex acoustic signals typically cannot be predicted from the simple sum of the discriminabilites associated with individual components of the signal. Understanding such failures of additivity is central to our understanding of complex sound analysis. The goal of this project is to elucidate the rules and mechanisms whereby individual stimulus components combine to influence the detection and discrimination of complex sounds. The project is designed to answer specific questions regarding listeners' abilities to integrate information within and across acoustic dimensions, to extract information contained in the pattern of the acoustic signal, and to perform under conditions of stimulus uncertainty. The data are also used to determine how listeners weight the information provided by different components of the signal, and how best to package the acoustic information so as to be most effectively processed by the listener.
