This study investigated the feasibility of a vocabulary-based teacher intervention to increase preschool teachers' production of complement clauses (e.g. "I wonder if we can put the monkey in the tree") in teacher-children play interactions. Using a multiple baseline across participants design we measured the impact of an intervention…

Generic sentences (e.g., "Birds lay eggs") convey generalizations about entire categories and may thus be an important source of knowledge for children. However, these sentences cannot be identified by a simple rule, requiring instead the integration of multiple cues. The present studies focused on 3- to 5-year-olds' (N = 91) use of…

Analysis of children's spoken narratives represents a potentially informative approach to language assessment within early childhood settings. Yet, narrative assessment is not readily amenable to at-scale use given the time needed to collect, transcribe, and analyze a child's narrative sample and the lack of consensus regarding what aspects of…

Bilingual children sometimes produce constructions influenced by their other language (cross-linguistic transfer). Transfer can often be predicted by the existence of overlapping and ambiguous constructions in both languages. In this paper, we investigate whether cross-linguistic transfer occurs when overlapping constructions exist, but there are…

An essential part of the human capacity for language is the ability to link conceptual or semantic representations with syntactic representations. On the basis of data from spontaneous production, Tomasello (2000) suggested that young children acquire such links on a verb-by-verb basis, with little in the way of a general understanding of…

This research investigates language-general and language-specific properties of the acquisition of argument structure. Ten French preschoolers enacted forty sentences containing motion verbs; sixteen sentences were ungrammatical in that the syntactic frame was incompatible with the standard argument structure for the verb (e.g. *"Le tigre va le…
