Abstract:
Objective: Previous research has shown the usefulness of utilizing auditory chimeras (i.e., interchanging the envelope and fine structure of two different sounds) in assessing a listener’s perception of the envelope and fine structure for an acoustic stimulus. However, research comparing and contrasting behavioral and electrophysiological responses to this stimulus type is scarce. Design: Two sets of chimeric stimuli were constructed by interchanging the envelopes and fine-structures of the rising /yi2/ and falling /yi4/ Mandarin pitch contours that were filtered through 1, 2, 4, 8, 16, 32, and 64 frequency banks. Behavioral pitch-perception tasks (through a single-interval, two-alternative, forced-choice paradigm) and electrophysiological responses (through the frequency-following response to voice pitch using validated scalp-recorded potential methods) were obtained from two groups of participants (native speakers of a tonal or nontonal language). Study Sample: Thirteen American and 13 Chinese adults were recruited. Results: A two-way analysis of variance showed significance (p & lt;0.05) within and across the filter bank and language background factors for the behavioral measurements to the lexical-tone chimeras, while the frequency-following response demonstrated a significance across filter banks, but not for language background. Conclusions: Frequency-following responses to voice pitch provide supplementary information on how chimeric stimuli are processed at the brainstem level.
