Abstract
Crosslanguage comparisons of brainstem-evoked potentials have revealed
experience-dependent plasticity in pitch representation for curvilinear
f0 contours representative of Mandarin tones. To assess the tolerance
limits of this experience-dependent selectivity, we evaluated cross-linguistically
(Chinese, English) the pitch strength and tracking accuracy of linear
rising and falling f0 ramps representative of Mandarin tones 2 and
4. No crosslanguage differences in pitch strength or accuracy were
observed for either tone, indicating that stimuli with linear rising/falling
ramps elicit homogeneous pitch representations at the level of the
brainstem regardless of language experience. We conclude that pitch
extraction at the brainstem level is critically dependent on specific
dimensions of pitch contours that native speakers have been exposed
to in natural speech contexts.
