Communicative Development Inventories (CDIs, parent-completed language development checklists) are a helpful tool to assess language in children who are unused to interaction with unfamiliar adults. Generally, CDIs are completed in written form, but in developing country settings parents may have insufficient literacy to complete them alone. We…

Two-year-old children often start asking questions with "where." In this study we test whether children understand "where" to mean route or absolute location and whether the size of the space or elevation made a difference. Previous research has documented developmental changes over the preschool years in children's non-verbal spatial reasoning.…

Tests the prediction that children acquiring left-branching languages will exhibit a preference for backward patterns of anaphora by presenting data from Japanese and Korean which show the prediction to be false. Findings support the view that any directionality preference for anaphora is the same for all languages. (Author/SED)

Examined the pattern of deletion of final "/t/" and "/d/" in word final consonant clusters in 3- and 4-year-old children (n=16) and their degree of mastery of phonological and grammatical constraints. Results indicate that children as young as three had mastered the phonological constraints on (-t, d) deletion and that the…

Investigates children's early lexical development in English and Korean and compares caregivers' linguistic input in the two languages. Results indicate that young Korean children use verbs productively with appropriate inflections and that, unlike in English, both verbs and nouns in Korean are dominant categories from the single-word stage. (39…
