Studies examining productive syntax have used varying elicitation methods and have tended to focus on either young children or adolescents/adults, so we lack an account of syntactic development throughout middle childhood. We describe here the results of an analysis of clause complexity in narratives produced by 354 speakers aged from four years…

This article reports results from a longitudinal study from age 4 to 7 of comprehension and production of narrative macrostructure in Swedish monolingual children (N = 17). "Baby Birds/Baby Goats" from the Multilingual Assessment Instrument for Narratives (LITMUS-MAIN) were used to elicit narratives and ask comprehension questions at age…

Using multi-level growth modeling, we examined the effect of several measures of maternal input on growth in children's word types from 15-54 months. Mothers and children engaged in a picture description task (N = 77) at 15, 24, 33, and 54 months; the frequency of children's observed word types at each wave was coded and additional independent…

Syntax has a high importance among linguistic parameters, and syntax-related problems are the most common in language disorders. Therefore, the present study aimed to design a Photographic Expressive Persian Grammar Test for Iranian children in the age group of 4-6 years and to determine its validity and reliability. First, the target…

Genetic and environmental relations between vocabulary and reading skills were explored longitudinally from preschool through Grades 2 and 4. At preschool there were strong shared-environment and weak genetic influences on both vocabulary and print knowledge but substantial differences in their source. Separation of etiology for vocabulary and…

Principal findings were that pictures of objects with more frequently occurring names were named more rapidly than those with less frequently occurring names; that language-impaired children named pictures less rapidly than chronological-age peers but more rapidly than language-age peers; and effects of frequency of occurrence were comparable for…

The process by which 55 preschool children acquire the meanings of dimensional and expressive terms was investigated in relation to Eve Clark's semantic feature hypothesis. (Author/MP)
