“…This view was further supported by Kuo et al [47], who found a P-MMR in adults with fine auditory discrimination. The researchers examined the impact of spectral resolution on MMN by using naturally spoken Mandarin tones and their cochlear implant (CI) simulations, which varied in the number of channels to simulate the natural stimuli.…”

Mismatch negativity (MMN) is an event-related potential component used to index automatic auditory change detection. Thus, MMN provides an excellent tool to assess the speech sensitivity of infants and children. Although MMN is well established in adults, the polarity and latency of mismatch responses (MMRs) in infants are highly inconsistent across studies. This paper aims to provide a comprehensive review of MMN studies of speech perception in early infancy. In particular, data from a series of MMN studies of Mandarin lexical tone, vowels, and initial consonants will be presented to demonstrate how phonological saliency, size of deviance, and neural maturation modulate MMRs in early infancy. These data suggest that MMN and positive MMRs index different functional characteristics and may provide information on when and how children’s speech perception becomes automatic at different developmental stages. By using MMN to index sensitivity to speech discrimination, dyslexic children usually show reduced or absent MMN, which supports the relationship between phonological sensitivity and literacy. However, children with attention deficit/hyperactivity disorder showed the typical MMN, but attenuated P3a and enhanced late discriminative negativity. Taken together, the MMR characteristics, including amplitude, peak latency, and the transition of polarity, may be used to index the maturation of speech development and for the early identification of children with atypical language development.

“…Notwithstanding, the P-MMR has also been observed in young children [36, 45, 46] and adults [47]. Maurer et al [45] used substantially lower frequency (1,000 vs. 1,060 or 1,030 Hz) and phoneme (/ba/ vs. /ta/ or /da/) deviances with a shorter interstimulus interval (ISI) relative to those in most previous studies.…”

“…We postulate the Chinese contrast required more attentional process than the Spanish contrast since infants had not yet formed perceptual routines for the low frequency English affricate / fricative. Therefore, the pMMR reflected enhanced attentional process for sounds that are more difficult to discriminate (Cheng et al, 2015;Kuo et al, 2014;Lee et al, 2012;Hisagi et al, 2010).…”

The present investigation explored the relation between the amount of language input and neural responses in English monolingual (N=18) and Spanish-English bilingual (N=19) infants. We examined the mismatch negativity (MMN); both the positive mismatch response (pMMR) and the negative mismatch response (nMMR), and identify a relationship between amount of language input and brain measures of speech discrimination for native and non-native speech sounds (i.e., Spanish, English and Chinese). Brain responses differed as a function of language input for native speech sounds in both monolinguals and bilinguals. Monolingual infants with high language input showed nMMRs to their native English contrast. Bilingual infants with high language input in Spanish and English showed pMMRs to both their native contrasts. The non-native speech contrast showed different patterns of brain activation for monolinguals and bilinguals regardless of amount of language input. Our results indicate that phonological representations of non-native speech sounds in bilingual infants are dependent on the phonetic similarities between their native languages.

“…Some studies have shown a robust p-MMR in young children (e.g., Lee et al, 2012;Maurer et al, 2003), and a few studies have shown a p-MMR in children aged 7 years in relation to auditory and speech perception (e.g., Shafer et al, 2000). Moreover, a significant p-MMR was elicited by the vowel /i/ in Chinese tone1 and tone4 in Mandarin-speaking participants aged between 18 to 24 years in a recent study (Kuo et al, 2013). Thus, the existence of the p-MMR is not a phenomenon that is specific to infants and preschoolers only.…”

Using a multiple-deviant oddball paradigm, this study examined second graders' brain responses to Cantonese speech. We aimed to address the question of whether a change in a consonant or lexical tone could be automatically detected by children. We measured auditory mismatch responses to place of articulation and voice onset time (VOT), reflecting segmental perception, as well as Cantonese lexical tones including level tone and contour tone, reflecting suprasegmental perception. The data showed that robust mismatch negativities (MMNs) were elicited by all deviants in the time window of 300-500 ms in second graders. Moreover, relative to the standard stimuli, the VOT deviant elicited a robust positive mismatch response, and the level tone deviant elicited a significant MMN in the time window of 150-300 ms. The findings suggest that Hong Kong second graders were sensitive to neural discriminations of speech sounds both at the segmental and suprasegmental levels.
