Because of its structural characteristics, specifically the prevalence of verb types in infant-directed speech and frequent pronoun-dropping, the Italian language offers an attractive opportunity to investigate the predictive effects of input frequency and positional salience on children's acquisition of nouns and verbs. We examined this…

Using the Multiple Indicator Cluster Survey, language comprehension and production were compared in a sample of 101,250 children aged 2 ; 00 to 9 ; 11 and a focus subsample of 38,845 children aged 2 ; 00 to 4 ; 11 from sixteen under-researched developing nations. In the whole sample, comprehension slightly exceeded production; correlations between…

Thirty middle- to upper middle-class monolingual Dutch speaking families consisting of at least a mother and a father completed the Infant Form "Words and Gestures" of the Dutch adaptation of the MacArthur Communicative Development Inventory for the same child at 1;1. Considerable inter- and intrafamily variation emerged in how two (or three)…

Discusses construction of the Hebrew Communicative Development Inventory (HCDI), an adaptation of the MacArthur Communicative Development Inventory (MCDI). The HCDI was administered to a stratified sample of Israeli mothers of 253 toddlers. Results are presented and compared with scores from the MCDI. Results indicate that conclusions concerning…

A methodological study of 33 2-year-olds shows that child speech occurs at about the same level in different settings (the familiar home vs. the unfamiliar laboratory), but that children speak more and in more differentiated ways with different people (mother vs. stranger). (Author/VWL)

Investigated individual variation in child vocabulary competence, evaluating mothers' sociodemographics, personalities, and vocabulary and children's' gender, social competence, and vocabulary competence. Specific aspects of children and mothers accounted for variation in child vocabulary knowledge and use. Child's gender and social competence and…

Using an events-history approach with 40 child-mother dyads, researchers examined prediction from three indexes of children's language, starting at 0;9, and mothers' verbal responsiveness at 0;9 and 1;1, investigating development of language milestones in year 2. Together, children's initial propensities to speak and mothers' responsiveness at the…

Describes a study designed to compare color-name with shape-name learning by three-year-old children in an experimentally controlled format. Results show that children learned color-label associates significantly more slowly than matched shape-label associates, and they committed more errors with colors than with shapes during learning. Provides a…
