Sounds in context: electrophysiological evidence for local bias in auditory processing

Research output: Contribution to conferenceConference abstract for conferenceResearchpeer-review

A sound is never just a sound. It is becoming increasingly clear that auditory processing is best thought of not as a one-way afferent stream, but rather as an ongoing interaction between interior processes and the environment. Even the earliest stages of auditory processing in the nervous system are colored by contextual information. This can be longterm contextual information, such as
knowledge of phonological or emotional categories, but can also be short-term local expectancies, such as the previous sound heard. In this paper, I present original electrophysiological data illustrating the early time-course of contextual influence on auditory processing in three different paradigms: a simple mismatch negativity paradigm with tones of differing pitch, a multi-feature mismatch negativity paradigm in which tones were embedded in a complex musical context, and a cross-modal paradigm, in which auditory processing of emotional speech was modulated by an accompanying visual context. I then discuss these results in terms of their implication for how we conceive of the auditory processing stream.
