Current models of the affinity between syntax and vocabulary are complex and recognize the contribution of bootstrapping and computational processes. To date, the mutual facilitation between these two constructs over time has not been studied in second language (L2) school children. The present study investigated longitudinally the direction and…

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…

Many studies suggest that preschoolers rely on individuals' histories of generating accurate lexical information when learning novel lexical information from them. The present study examined whether children used a speaker's accuracy about one kind of linguistic knowledge to make inferences about another kind of linguistic knowledge, focusing…

What is the role of oral language in reading competence during the transition to school? Is oral language in preschool best conceptualized as vocabulary knowledge or as more comprehensive language including grammar, vocabulary, and semantics? These questions were examined longitudinally using 1,137 children from the National Institute of Child…

To explore how online speech processing efficiency relates to vocabulary growth in the 2nd year, the authors longitudinally observed 59 English-learning children at 15, 18, 21, and 25 months as they looked at pictures while listening to speech naming one of the pictures. The time course of eye movements in response to speech revealed significant…

Used growth curves and dynamic-systems modeling to examine early lexical and grammatical development of one male child. Found that lexical development described a pattern of logistic growth. Plural growth began after reaching a threshold in vocabulary size. Lexical growth slowed as plural growth increased, and increased when plural use reached…
