Signal- and Listener-Based Factors in Complex Auditory Pattern Perception

Abstract

The research conducted during the second year of AFOSR grant 91 investigated fundamental issues in the early processing of speech and similarly complex acoustic signals. The research pursued the information processing goal of specifying the levels of analysis that occur between the initial sensory coding of the signal, and the recognition of the phonetic sequence it conveys. Five experiments provided evidence for the existence of at least three qualitatively different levels of perceptual analysis. The data help to specify the properties of each level, including a locus (peripheral vs. central), a stimulus domain, and the mechanisms affected by repeated stimulation. The convergence across several different approaches used to determine levels of analysis supports the three-level model.
