Key points
- Toddler vocabulary skills are predicted by parents using diverse and sophisticated language.
- Preschooler vocabulary skills are predicted by parents using decontextualized language (e.g., narrative).
- These quality-of-speech effects persist after controlling for socioeconomic status, input quantity, and prior vocabulary.
- The study tracked 50 parent-child dyads longitudinally from 18 to 54 months of child age.

Abstract
Quantity and quality of caregiver input was examined longitudinally in a sample of 50 parent-child dyads to determine which aspects of input contribute most to children's vocabulary skill across early development. Measures of input gleaned from parent-child interactions at child ages 18, 30, and 42months were examined in relation to children's vocabulary skill on a standardized measure 1year later (e.g., 30, 42, and 54months). Results show that controlling for socioeconomic status, input quantity, and children's previous vocabulary skill; using a diverse and sophisticated vocabulary with toddlers; and using decontextualized language (e.g., narrative) with preschoolers explains additional variation in later vocabulary ability. The differential effects of various aspects of the communicative environment at several points in early vocabulary development are discussed.
