چکیده

This study examined how maturation and the size of deviance affect the development of mismatch responses to Mandarin lexical tones by a multi-deviant oddball paradigm with both large deviant T1/T3 and small deviant T2/T3 pairs in newborns and 6-month-olds. The T1/T3 pair elicited a positive mismatch response (P-MMR) at birth but an adult-like mismatch negativity (MMN) at 6 months of age. For the T2/T3 pair, no significant MMR was seen in newborns, whereas a P-MMR was found when infants are 6 months old. Results suggest that the developmental trajectories of MMRs are dependent on the neural maturation and the discriminability of tonal changes.

Developmental Changes in Mismatch Responses to Mandarin Consonants and Lexical Tones from Early to Middle Childhood

The purpose of this study was to use mismatch responses (MMRs) to explore the dynamic changes of Mandarin speech perception abilities from early to middle childhood. Twenty preschoolers, 18 school-aged children, and 26 adults participated in this study. Two sets of synthesized speech stimuli varying in Mandarin consonant (alveolo-palatal affricate vs. fricative) and lexical tone features (risin...

Mismatch responses to lexical tone, initial consonant, and vowel in Mandarin-speaking preschoolers.

The present study investigates how age, phonological saliency, and deviance size affect the presence of mismatch negativity (MMN) and positive mismatch response (P-MMR). This work measured the auditory mismatch responses to Mandarin lexical tones, initial consonants, and vowels in 4- to 6-year-old preschoolers using the multiple-deviant oddball paradigm. The data showed the coexistence of MMN a...

Domain specificity of lexical tone perception in early infancy: lexical tones versus musical tones

In the current study, we tested the perception of pitch variations in early infancy from a domain general perspective for two auditory domains: speech and music. 4-month-old Dutch infants were tested on their discrimination of a musical relative pitch difference, a musical absolute pitch difference, and a Mandarin lexical tone difference. Our results showed that the infants failed to discrimina...

Categorization of Lexical Tones in Mandarin-Learning Infants

It is well-known that children are born with the perceptual ability to discriminate not only native phonetic contrasts, but also non-native ones. However, recent research suggests that not all contrasts are equally discriminable. Children cannot discriminate some acoustically similar phonetic contrasts early in infancy. They need a certain period of exposure with these contrasts to learn to dis...

Developmental changes in brain response to speech perception in late-talking children: A longitudinal MMR study

This study used a longitudinal design to examine the development of mismatch responses (MMRs) to Mandarin lexical tones, an index of neural speech discriminative responses, in late talkers and typical controls at 3, 5, and 6 years of age. Lexical tones are phonetic suprasegments that distinguish the lexical meanings of syllables in tonal languages. The 2 year-old late talkers were later divided...
