This meta-analysis examined associations between the quantity and quality of parental linguistic input and children's language. Pooled effect size for quality (i.e., vocabulary diversity and syntactic complexity; k = 35; N = 1,958; r = .33) was more robust than for quantity (i.e., number of words/tokens/utterances; k = 33; N = 1,411; r = .20) of…

Three types of metalinguistic awareness and their relation to socioeconomic status, vocabulary, reading readiness skills, and reading acheivement were longitudinally studied in a sample of 40 kindergartners and 43 first graders.

At three years, children were deficit in receptive vocabulary and object-naming, and at five years, in phonemic awareness and letter-sound knowledge. These deficits were not found in normal reading children…
