Vocabulary Size is Correlated with Non-Native Tone Sensitivity In English Learning Infants

چکیده
In many languages, tone (i.e., pitch patterns) is part of the phonological system; two words with the same sequences of segments can differ only in tone. Tone does not distinguish word meanings in English, so English-learning infants can ignore tone when learning words, but do they? We examined the encoding of tonal detail in word learning by monolingual English-learning 14and 17-month-olds. Infants were habituated to a novel word with a Mandarin tone (/ká/) paired with a novel object. Test trials alternated between the same pairing (Same), and the same object paired with the word with a different tone (/kà/, Switch). Longer looks to the unfamiliar mapping indicate infants noticed the switch and attended to tone contrasts. Overall, neither age group discriminated the tone contrast; however, infants with larger vocabularies looked longer to the novel mapping (r=.32, p=.007), suggesting a common underlying mechanism between general word learning and tone sensitivity.

Referential labeling can facilitate phonetic learning in infancy.
All languages employ certain phonetic contrasts when distinguishing words. Infant speech perception is rapidly attuned to these contrasts before many words are learned, thus phonetic attunement is thought to proceed independently of lexical and referential knowledge. Here, evidence to the contrary is provided. Ninety-eight 9-month-old English-learning infants were trained to perceive a non-nati...
متن کاملConstraints on Tone Sensitivity in Novel Word Learning by Monolingual and Bilingual Infants: Tone Properties Are More Influential than Tone Familiarity
This study compared tone sensitivity in monolingual and bilingual infants in a novel word learning task. Tone language learning infants (Experiment 1, Mandarin monolingual; Experiment 2, Mandarin-English bilingual) were tested with Mandarin (native) or Thai (non-native) lexical tone pairs which contrasted static vs. dynamic (high vs. rising) tones or dynamic vs. dynamic (rising vs. falling) ton...
متن کاملPerceptual Improvement of Lexical Tones in Infants: Effects of Tone Language Experience
To learn words in a tonal language, tone-language learners should not only develop better abilities for perceiving consonants and vowels, but also for lexical tones. The divergent trend of enhancing sensitivity to native phonetic contrasts and reduced sensitivity to non-native phonetic contrast is theoretically essential to evaluate effects of listening to an ambient language on speech percepti...
متن کاملLimits on Monolingualism? A Comparison of Monolingual and Bilingual Infants’ Abilities to Integrate Lexical Tone in Novel Word Learning
To construct their first lexicon, infants must determine the relationship between native phonological variation and the meanings of words. This process is arguably more complex for bilingual learners who are often confronted with phonological conflict: phonological variation that is lexically relevant in one language may be lexically irrelevant in the other. In a series of four experiments, the...
متن کاملThe Influence of Tonal Awareness and Musical Experience on Tone Word Learning
Phonological awareness has been shown to play a significant role in language learning. The present study examined the effect of improving pitch identification ability and tonal awareness on Cantonese tone word learning. A group of native English listeners received three days of Cantonese tone training to first improve their tone perception. They then learned the meanings of 15 vocabulary items ...
