Spontaneous Lexical Overlap in Early Conversations
This study piloted CHIPUTIL, an automated tool in CLAN for analysing sequential lexical overlap in parent–child conversations. In a sample of 44 dyads (child age M = 1;9), child spontaneous lexical overlap was positively associated with parent imitations and expansions, across the conversation and within sequential turns. Children were more than twice as likely to respond with lexical overlap when parents first produced an imitation or expansion.…
Parent Responsivity, Language Input, and the Development of Simple Sentences
This study explored responsive and linguistic parent input features during parent-child interactions and investigated how four input categories related to children’s production of diverse, simple sentences. Of primary interest was parent use of responsive, simple declarative input sentences. Responsive and linguistic features of parent input to 20 typically developing toddlers at 1;9 were coded during play in a laboratory playroom, then classifie…
Diversity matters
The contribution of parent input to children's subsequent expressive verb diversity was explored in twenty typically developing toddlers with small verb lexicons. Child developmental factors and parent input measures (i.e. verb quantity, verb diversity, and verb-related structural cues) at age 1;9 were examined as potential predictors of children's verb production in spontaneous language samples at age 2;3. Parent verb input diversity, rather tha…
Case marking uniformity in developmental pronoun errors
The purpose of this study was to determine if children acquire grammatical case as a unified system or in a piecemeal fashion. In English language acquisition, many children make developmental errors in marking case on subject position pronouns (e.g., Me do it, Him like it). It is unknown whether children who produce pronoun case errors with first person pronouns also produce errors with third person pronouns. This finding would be expected if ca…
