Abstract : A series of experiments that treated auditory perception in humans was conducted. These investigations were at the information processing level and were structured to test hypotheses of sensory filtering, feature detection, the organization of a matching system, and the possible role of the motor theory of speech perception in the perception of speech. The studies include multidimensional scaling investigations, tests of the motor theory of speech perception, studies on subphonemic or distinctive features of speech, and experiments on the perceived order of short auditory events. The results of these studies support the idea that the auditory system operates as a feature detector and that these features may relate to articulatory properties of the vocal tract. Further evidence of features was found in short-term recall of phonemes where the error responses indicated that features were retained where phonomes were forgotten. Investigations of perceived order of short auditory events indicate that similar stimuli are grouped together by the auditory system and, in some instances, are heard in a perceptual order that is different from the actual physical order of the stimuli.
