Abstract

The present study investigated the temporal course of neural discriminations of acoustic cues of English lexical stress (i.e., pitch, intensity and duration) in Cantonese-speaking children. We used an event-related potential (ERP) measure with a multiple-deviant oddball paradigm to record auditory mismatch responses to four deviants, namely, a change in pitch, intensity, or duration, or a change in all three acoustic dimensions, of English lexical stress in familiar words. In the time window of 170–270 ms, we found that the pitch deviant elicited significant positive mismatch responses (p-MMRs) and that the duration deviant elicited a mismatch negativity (MMN) response as compared with the standard. In the time window of 270–400 ms, the intensity deviant elicited a significant p-MMR, whereas both the duration and the three-dimension changed deviants elicited significant MMNs. These results suggest that Cantonese-speaking children are sensitive to either single or convergent acoustic cues of English words, and that the relative weighting of pitch, intensity and duration in stress processing may correlate with different ERP components at different time windows in Cantonese second graders.
