| summary | It has been posited that perception involves inferring the causes of our sensory input by combining that input with predictions derived from our learned/evolved model of the world. And it has been suggested that such predictions play a role in language processing. More specifically, it has been proposed that predictions – based on experience and context – interact with speech signals at each of several hierarchical stages that transform acoustic patterns into categorical representations that convey meaning. However, neurophysiological evidence of such interactions remains elusive – particularly in the context of natural speech. In this talk, I will describe a number of experiments aimed at identifying scalp and intracranial electrophysiological (EEG) indices of speech predictions and of the effects of those predictions on speech encoding along the processing hierarchy. This will include discussion of experiments wherein we manipulate the prior information available to participants before they hear degraded speech. And it will also include experiments wherein participants simply listen to naturalistic, narrative speech. Finally, I will discuss the potential utility of these paradigms for research on the putatively aberrant influence of prediction on perception in certain clinical conditions such as autism and schizophrenia. |
