Purpose: The purpose of this study was to better understand the contributors to input informativeness for tense marking, a predictor of child tense marking productivity (Hadley, Rispoli, Fitzgerald and Bahnsen, in press). The contributors explored were parent-toddler interaction style, register, and constraints of English verb typology. Method: The participants were 15 parent-toddler dyads. Language samples were collected when the children were 21 months of age. Verbs in child-directed speech were coded for linguistic form (e.g., imperative, modal, copula, etc.). The communicative function of utterances and the form of questions directed toward children were also coded. Results: Copula was the most frequent verb form rewarding a +Tense grammar while imperatives were the most frequent verb form rewarding a –Tense grammar. Directives, other-focused descriptives and use of reduced questions were the three variables that overlapped most with input informativeness. Conclusions: Understanding how parent-toddler interaction style overlaps with informativeness has implications for family-focused clinical interventions designed to modify characteristics of parents’ child-directed speech.
