We investigated toddlers' phonological representations of common vowel-initial words that can take on multiple surface forms in the input. In French, liaison consonants are inserted and are syllabified as onsets in subsequent vowel-initial words, for example, petit /t/ éléphant [little elephant]. We aimed to better understand the impact on…

The study assessed 30-month-old Mandarin-speaking children's awareness of aspectual distinctions involving the perfective marker "le" and the imperfective marker "zhe" in a preferential looking experiment. In the experiment, we presented our child subjects with a choice between two video clips (one depicting a closed event and…

We examined how toddlers process lexical ambiguity where different underlying forms are neutralized at the surface level. In a preferential-looking procedure, French-learning 30-month-olds were familiarized with either liaison-ambiguous phrases (i.e., sentences containing a determiner and a non-word, e.g., "ces /z/onches," "these…

This study examined abstract syntactic categorization in infants, using the case of grammatical gender. Ninety-six French-learning 14-, 17-, 20-, and 30-month-olds completed the study. In a preferential looking procedure infants were tested on their generalized knowledge of grammatical gender involving pseudonouns and gender-marking determiners.…

Function words support many aspects of language acquisition. This study investigated whether toddlers understand the number feature of determiners and use it for noun comprehension. French offers an ideal "test case" as number is phonetically marked in determiners but not in nouns. Twenty French-learning 24-month-olds completed a split-screen…

Maternal infant-directed speech in Mandarin Chinese and Turkish (two mother-child dyads each) was examined to see if cues exist in input that might assist infants' assignments of words to lexical and functional item categories. Results show that sets of distributional, phonological, and acoustic cues distinguishing lexical and functional items are…
