Sound Research in Media Processing: One Scholar's Audio Adventures

摘要

Visual media have been the most prominent stimuli used in research on cognitive processing of media. However, a career as a radio announcer and commercial producer served as a springboard into my own scientific investigations exploring how the brain processes audio messages.  Taking this “road less travelled” has resulted in a series of studies which provide the focus of the talk.  I will begin by briefly arguing in favor of the presumption that the human cognitive system evolved in such a way as to produce a reflexive cognitive response to auditory changes in the immediate environment.  This established, I will then present experimental data showing that this system—which evolved as a result of survival benefits in a concrete/physical world—has modern day consequences on how we processing auditory information in modern mediated environments.  The first results are from experiments designed to identify the precise auditory structural features of media capable of eliciting this reflexive cognitive response.  A second series of studies will be presented where the primary experimental variation consisted of changing the number of these structural features in audio messages.  The talk will conclude with results from my most current scholarly audio adventure, one where hypotheses are tested concerning not merely the number of auditory changes that occur within a message, but also the relative cognitive load that these changes impose on the listener.
