    Abstract: Speech perception during the first year reflects increasing attunement to native language phonetic features, but the mechanisms underlying this development are not well understood. Reductions in non-native phonetic discrimination have been linked to improvement in native phonetic discrimination and later vocabulary growth (Kuhl et al., 2005), and performance on nonlinguistic tasks (Lalonde and Werker, 1995). The present study examined links between native and non-native voice onset time discrimination, receptive vocabulary (MacArthur-Bates CDI), and cognitive control abilities at 11 months. Infants (n=18) completed a double-target conditioned head turn task and two nonlinguistic tasks requiring attentional control and resistance to irrelevant cues (means-end and detour-reaching object retrieval). Infants with CDI scores above the median showed higher native discrimination scores, t(16)=2.15 0.05, but no group differences for the nonnative contrast. Infants with scores above the median on either cognitive task showed worse discrimination of the nonnative contrast (means-end, t(15)=2.27p0.04; detour-reaching, t(15)=3.49, p.01), but no group differences for the native contrast. These results suggest that cognitive control plays a role in infants’ ability to ignore acoustic cues that are irrelevant to their native languages phonemic categories.

    Consequences of short-term language exposure in infancy on babbling.

    Abstract: Kuhl et al. [Proc. Natl. Acad. Sci. U.S.A. 100, 9096–9101 (2003)] showed that the decline in the discrimination of non-native perceptual contrasts observed during development can be reversed with short-term exposure to a non-native language. In this poster, the question of whether short-term exposure also impacts the speech produced by infants is addressed. For this purpose, 9–10-month-old infants from monolingual English-speaking households were exposed to Spanish for a total of 5 h over 6 weeks (12 25-min sessions). At the end of this exposure, babbling data were collected from the infants in two sessions with (a) an English-speaking parent and (b) a Spanish-speaking research assistant. In this experiment, adult listeners were tested in their ability to identify the babbling produced by these infants as English or Spanish. Canonical syllables and multi-syllabic utterances from these sessions were played to adult native speakers of English and Spanish, who identified the tokens as English or Spanish using a forced-choice paradigm. Results will be discussed in the context of the literature on short-term exposure as well as the effects of social interactions on language acquisition.

    Abstract: Previous behavioral studies have shown improved sensitivity to native-language contrasts and reduced sensitivity to non-native phonetic contrasts when comparing 6–8- and 10–12-month-old monolingual infants. It has been argued that exposure to language dedicates neural networks to the acoustic properties of native-language speech, and that, in adulthood, this commitment interferes with nonnative speech processing [native language neural commitment or (NLNC)]. There are very few studies on how early speech perception in bilinguals relates to future language advancement. Recently it has been shown that infants’ early native-language speech perception skill predicts their later success at language acquisition. In the present investigation, we examined how brain measures of speech perception in bilingual infants and socio-cultural factors of their environment predict later vocabulary growth. Our results showed excellent neural discrimination of both English and Spanish phonetic contrasts in 12-month-old infants, distinguishing them from monolingual infants. To our knowledge, this is the first study of bilingual infants using a brain measure to show that bilingual infants’ speech specialization includes both languages by the end of the first year of life.

    Abstract: Previous research has linked increasing cognitive abilities to reductions in sensitivity to nonnative phonemes toward the end of the first year, but found no association between cognitive skills and native speech perception (Conboy et al., 2006; Lalonde & Werker, 1995). The present study examined cognitive abilities and brain activity to second-language (L2) phoneme contrasts in infants who had short-term experience with the L2: we predicted better cognitive skills in infants with better discrimination of the L2 contrast. Seventeen infants from monolingual English homes completed event-related potential (ERP) speech perception testing and nonlinguistic tasks requiring attentional flexibility, memory, and inhibitory control at 11 months, after twelve Spanish play sessions from 9.5 - 10.5 months. An ERP oddball paradigm assessed discrimination of English and Spanish contrasts (English: voiced /da/ vs. voiceless-aspirated [tha]; Spanish: prevoiced /da/ vs. voiceless-unaspirated /ta/). Infants showed broad mismatch negativity (MMN) discriminatory responses to both contrasts. Larger Spanish MMN amplitudes were linked to better performance on cognitive tasks (detour-reaching object-retrieval and the A not B task) (Fisher's exact test, p=.01), suggesting a role for specific cognitive abilities in the early stages of phonetic learning. There was no association between English MMN amplitudes and cognitive skills.
