Weizman, Zehava Oz; Snow, Catherine E.
Developmental Psychology, v37 n2 p265-79 Mar 2001
Studied nearly 150,000 maternal word-tokens used by low-income mothers in mother-child conversations. Found that 99 percent of maternal lexical input consisted of 3,000 most frequent word. Density of sophisticated words and density with which such words were embedded in helpful/instructive interactions at age 5 predicted over one-third of variance in children's vocabulary in kindergarten and second grade.
