This study compared pronoun use in individuals with autism to their typically developing peers via meta-analysis and systematic review of 20 selected articles to examine differences in overall pronoun usage as well as in personal, ambiguous, possessive, reflexive, and clitic pronoun usage. Summary effects indicated significant differences between…

The purpose of this study is to examine the bidirectional relationship between children's language development and challenging behaviors as well as the moderating roles of gender and race/ethnicity. We conducted a number of structural equation modeling analyses with a national representative sample (N = 2,462) of Head Start children from the 2014…

The Head Start Family and Child Experiences Survey (FACES) and the American Indian and Alaska Native Head Start Family and Child Experiences Survey (AIAN FACES) are separate studies done successively over time. One goal for these studies is to provide a national picture of children's readiness for school. In this research brief, the authors use…

Using a nationally representative sample of 3- and 4-year-old Spanish-speaking dual language learners (DLLs) attending Head Start (N = 654), this study examined whether mean levels of and variability in peers' English receptive vocabulary skills were associated with DLLs' English and Spanish receptive vocabulary skills in the spring. In addition,…

The present study investigated whether the bidirectional cross-lagged paths between teacher--child language interactions and receptive vocabulary would be significantly different between English language learner (ELL) and non-ELL children. The FACES 2009 cohort was used to address the research goals. Cross-lagged analysis was conducted with the…

American Sign Language (ASL) is one of the most commonly taught languages in North America. Yet, few assessment instruments for ASL proficiency have been developed, none of which have adequately demonstrated validity. We propose that the American Sign Language Discrimination Test (ASL-DT), a recently developed measure of learners' ability to…

Individuals with autism spectrum disorder (ASD) have difficulty generalizing--i.e., relating new stimuli to past experiences. Few experimental studies have addressed this weakness, despite its impact on intervention effects. In a reanalysis of data (de Marchena et al. "Cognition" 119(1):96-113, 2011), we tested a novel form of…

The standard scoring of the CLASS PreK produces three domain scores that are widely used in research, practice and policy. Despite these domains being based on developmental theory and research, limited empirical evidence exists for the three-domain structure as operationalized in the CLASS PreK. Using the 2009 and 2014 Head Start Family and Child…

Previous studies have demonstrated that various psychosocial risks are associated with poor cognitive functioning in children, and these risks frequently cluster together. In the current longitudinal study, we tested a model in which it was hypothesized that cumulative psychosocial adversity of mothers would have deleterious effects on children's…
