Wh-words in Mandarin Chinese exhibit quantificational variability. Aside from a typical interrogative reading, wh-words can also have an existential indefinite reading or a universal reading. Which reading it is depends on the linguistic environments in which they occur. The present study investigates Mandarin-speaking children's sensitivity to the linguistic environments for the noninterrogative use of wh-words: the existential reading and the universal reading. The results show that young children exhibited adultlike sensitivity to the licensing environments for the noninterrogative use of wh-words. Given the difficulty that children may have in using the input data to learn the interpretation of wh-words and the early emergence of this knowledge, we propose that the licensing mechanism for the noninterrogative use of wh-words is innate.

This study examined the relationship between performance on standardized measures of language proficiency and conversational measures of the same features used in academic discourse among 24 monolingual and 25 bilingual kindergarteners. Academic discourse performance was considered for both its linguistic and its genre features in two discourse forms: narrative and explanation. Bilinguals performed more poorly than monolinguals on standardized measures of language proficiency, yet they performed similarly to monolinguals in the discourse-based linguistic and genre features. Moreover, genre features were more strongly related to linguistic features assessed through discourse than to standardized tests of these same features. These findings indicate that standardized measures of language proficiency underrepresent the abilities of bilingual children and that children's second language proficiency may be more accurately reflected in conversation.

The aim of the present study was to investigate changes in voicing identification, discrimination, and categorical perception induced by identification training centered on three different training values. One group of French-speaking adults was trained across a universal auditory boundary (−30 ms voice onset time), and two other groups were trained across arbitrary boundaries (−45 or −60 ms voice onset time). A control group did not receive any training. The results showed that both the −30 and the −45 training groups exhibited a 10 ms shift in the identification boundary. Moreover, for the −30 training group, discrimination and categorical perception changed around the French phonological boundary. These results illustrate the possibility of modifying the French phonological perception after short-time training, particularly when centered on a universal boundary. However, training only had limited effects and even strengthened the phonological boundary, congruent with the hypothesis that this boundary is acquired by a perceptual “coupling” between universal boundaries.

Expression of spatial motion shows wide variation as well as patterned regularities across the world's languages (Talmy, 2000), and events involving the traversal of a spatial boundary impose the tightest typological constraints in the lexicalization of motion, providing a true test of cross-linguistic differences. Speakers of verb-framed languages are required by their language not to use manner verbs in marking the change of location across boundaries (Aske, 1989). Here we test the strength of the boundary-crossing constraint and ask how speakers convey motion events when the constraints imposed by the experimental task are at odds with the constraints imposed by their native language. We address this question by comparing adult speakers’ description of motion scenes that involve the traversal of a spatial boundary in two typologically distinct languages: English and Turkish. Using an experimental paradigm that imposes competing demands with the semantic structure of Turkish, we compare Turkish speakers’ description of boundary-crossing scenes to that of English speakers. We find strong cross-linguistic differences in speakers’ verb choice (manner vs. path) and event segmentation (one vs. many), suggesting that boundary-crossing constraint can serve as a reliable test to detect the typological class of a language.
