摘要：Various theoretical views regarding the relationship between speech perception and production can be found as towhether perception and production are supported by the same (Hickok, 2001) or different phonologicalrepresentations (Hillis, 2001), or whether perception must involve access to the motor system (Liberman &Mattingly, 1985). Double dissociation between language comprehension and production exhibited by languageimpaired individuals is compatible with separate input and output representations or functionally distinct access forprocesses in the two modalities, but challenges accounts of production-based perception and unitary representationssupporting perception and production. This paper reports preliminary behavioural and electrophysiological findingsof neurologically unimpaired speakers of Cantonese who produce all six distinctive tones in the language but fail todiscriminate certain tonal contrast confirmed by event-related potentials (ERP).
