Evidence shows individual variation in lexical acquisition as a function of socioeconomic status and linguistic input. Research has primarily involved English-speaking populations and considered only mothers' child-directed speech.

Investigation focused on three questions: (1) When a response to a wh-question is incorrect,…

Examined how child care experiences related to cognitive and language development from birth through age 3.
