We explored longitudinal effects of a two-generation preschool programme on receptive language scores in children (n = 78) at age 10 years, living with low income. Scores at four time-points, programme intake, exit, age 7, and age 10 years were measured using the "Peabody picture vocabulary test" (3rd ed.). Effects of culture…

Research Findings: This study examined whether approaches to learning moderate the association between home literacy environment and English receptive vocabulary development. The Head Start Family and Child Experiences Survey (2003 cohort) was used for analysis. Latent growth curve modeling was utilized to test a quadratic model of English…

Background: The sociocommunicative problems in autism spectrum disorder (ASD) are traditionally linked to impairments in Theory of Mind (ToM), the ability to ascribe mental states to others. Although ToM impairments are consistently reported in young children with ASD, findings on more advanced ToM understanding in older individuals with…

Using data from the Early Childhood Longitudinal Survey--Birth cohort ("N" = 6,450), the present study hypothesized that 48-month-old children of divorced mothers would score lower on emerging literacy than the children of formerly cohabiting mothers, compared with the children of mothers in stable marriage. The children of mothers who…

A study was conducted in 26 Head Start classrooms with 264 children to compare the effect of a read aloud plus extension activities intervention over a control group to the effect of a read aloud only intervention over a control group on preschool children's vocabulary. Children were assessed before and after the intervention on target vocabulary…

Recent advances in methods and computer software for longitudinal data analysis have pushed researchers to more critically examine developmental theories. In turn, researchers have also begun to push longitudinal methods by asking more complex developmental questions. One such question involves the relationships between two developmental…

Practical considerations associated with local norms development are discussed. A local norming project administering the Peabody Picture Vocabulary Test-Revised to 398 elementary Mexican--American children is presented in detail. The utility of local norms and their interpretation is discussed in the context of this local project. (Author/BW)

Purpose: This study examined the cognitive demands of 2 selection techniques in augmentative and alternative communication (AAC), direct selection, and visual linear scanning, by determining the memory retrieval abilities of typically developing children when presented with fixed communication displays. Method: One hundred twenty typical children…

Analysis of data on 2,000 children from the National Longitudinal Survey of Youth suggests that maternal intelligence is a significant predictor of scores on the Peabody Picture Vocabulary Test-Revised. The HOME Inventory short forms used in the study are appended. (LB)
