Happy babies, chatty toddlers: infant positive affect facilitates early expressive, but not receptive language.
Eighty-three mother-infant dyads participated in this study. Positive affect (PA) broadly, along with fine-grained aspects of PA, was measured at 10 months of age. Language was measured at 14 months. Infant PA predicted expressive, but not receptive, language. The implications of these findings are discussed.
