Mechanisms of Human Auditory Localization
Abstract
Three experiments were completed. The first was a methodological study of the relationship between two different methods of measuring auditory thresholds and their possible relationships to supra-threshold tasks. The second experiment replicated, with improved methods, an earlier experiment which measured the accuracy of auditory localization with and without pinnae. The findings were striking and conclusive: in the absence of head movement, pinnae even someone else's pinnae, appear to be necessary for accurate auditory localization. The third experiment compared the effectiveness of different stimuli in an auditory localization task. It was expected that increasing the informational content of the stimulus would improve localization performance. However, the findings were inconclusive.
