Perceptual Experience

How we perceive our world depends critically upon experience with structure in the environment. Much of the study of high-level vision, for example, is focused upon the way the visual system comes to be organized in a way that reflects experienced regularities in optical input. Experience is undoubtedly of equal importance in development and operation of the auditory system, yet somewhat less emphasis has traditionally been placed on experience for hearing. We know that speech perception is critically dependent upon experience with the different types of speech sounds that are listened to in one's native language environment, and we are always engaged in studies to investigate how auditory perception of speech and other complex sounds is shaped by experience with structure in the acoustic world.

In some cases, we study how listeners' perceptual performance is shaped through experience with statistical regularities within and between sets of novel sounds. We also have used nonhuman animal subjects in studies in which we can precisely control experience with sounds, typically speech. We also are engaged in multiple efforts to develop realistic computational models for the way experience shapes perception. One current interest is how experience with structured sound environments gives rise to different patterns of cortical neural development. We also are studying the classic phenomenon of categorical perception is a natural consequence of experience with statistical regularities in the environment.
