The aim was to investigate the staff's language support towards children in Swedish preschools after eight weeks of structured language support. This study took place after an initial study of six weeks' language support. To identify support of Language Learning Environment, Opportunities and Interactions an observation-tool was used. Structured…

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…

Background: Many studies have analysed language development in children with Down syndrome to understand better the nature of their linguistic delays and the reason why these delays, particularly those in the morphosyntactic area, seem greater than their cognitive impairment. However, the prosodic characteristics of language development in…

Across a diverse range of languages, children proceed through similar stages in their production of causal language: their initial verbs lack internal causal structure, followed by a period during which they produce causative overgeneralizations, indicating knowledge of a productive causative rule. We asked in this study whether a child not…

This paper represents an effort to explain the language development of the child within the analytic frame of overtly observable data and without recourse either to mathematical models or to postulating hypothetical underlying forms. From longitudinal studies of two-year old children conducted by the author as well as from similar data reported in…
