Background: This study evaluates the effects of a language and literacy intervention for children with Down syndrome. Methods: Teaching assistants (TAs) were trained to deliver a reading and language intervention to children in individual daily 40-min sessions. We used a waiting list control design, in which half the sample received the…

The purpose of this study was to examine the hypothesis that helping preschoolers learn words through categorization may enhance their ability to retain words and their conceptual properties, acting as a bootstrap for self-learning. We examined this hypothesis by investigating the effects of the World of Words instructional program, a supplemental…

The French language development of children adopted (n = 24) from China was compared with that of control children matched for socioeconomic status, sex, and age. The children were assessed at 50 months of age, on average, and 16 months later. The initial assessment revealed that the 2 groups did not differ with respect to socioemotional…

The purpose of this design experiment was to research, test, and iteratively derive principles of word learning and word organization that could help to theoretically advance our understanding of vocabulary development for low-income preschoolers. Six Head Start teachers in morning and afternoon programs and their children (N = 89) were selected…

This school-based randomized controlled trial tested the efficacy of 2 expressive writing interventions among youth living in high-violence urban neighborhoods. Seventeen classrooms (n = 258 seventh graders; 55% female; 91% African American/Black) from 3 public schools were randomized to 3 conditions in which they wrote 8 times about a…

Little research has precisely defined the population of students participating in alternate assessments based on alternate academic achievement standards (AA-AAAS). Therefore, the purpose of this article is twofold: (a) explicate the findings of a multistate study examining the characteristics of the population of students participating in…

Self-regulation emerges throughout early childhood, and predicts later success in socially and cognitively challenging situations. Vygotsky proposed that symbols, particularly words, serve as mental tools to be used in service of self-regulation. Cross-sectional research indicates a positive but inconsistent association between language and…

The longitudinal intervention study reported here is the first to investigate the efficiency of computer learning software specifically designed for dyslexic Swiss German learners of Standard German as a second language (L2) and English as a third language (L3). A total of 40 subjects (20 of them dyslexics and 20 of them nondyslexics; 10 students…

We examined growth trajectories of writing and the relation of children's socioeconomic status and language and/or speech impairment to the growth trajectories. First-grade children (N = 304) were assessed on their written composition in the fall, winter, and spring, and their vocabulary and literacy skills in the fall. Children's SES had a…

This study addressed two aims: First, to examine the quality of adult shared book-reading behaviors for teachers and caregivers of children with communication impairments (CI) and, second, to compare the level of child literacy engagement during the teacher-led (group) and caregiver-led (one-on-one) shared book-reading sessions. Sixteen children…

A predominant theory regarding early stroke and its effect on language development, is that early left hemisphere lesions trigger compensatory processes that allow the right hemisphere to assume dominant language functions, and this is thought to underlie the near normal language development observed after early stroke. To test this theory, we…

Purpose: To describe the concurrent validity and classification accuracy of 2 Spanish parent surveys of language development, the Spanish Ages and Stages Questionnaire (ASQ; Squires, Potter, & Bricker, 1999) and the Pilot Inventario-III (Pilot INV-III; Guiberson, 2008a). Method: Forty-eight Spanish-speaking parents of preschool-age children…

Background: Social and communication impairments are core deficits and prognostic indicators of autism. We evaluated the impact of supplementing a comprehensive intervention with a curriculum targeting socially synchronous behavior on social outcomes of toddlers with autism spectrum disorders (ASD). Methods: Fifty toddlers with ASD, ages 21 to 33…

We present 4 experiments investigating dynamic and flexible aspects of semantic activation spread during speech planning. In a semantic blocking paradigm, pictures of objects were presented in categorically homogeneous blocks consisting of semantic category members (e.g., foods), in blocks consisting of seemingly unrelated objects that could…

In the UK there is much concern about the educational progress of children from areas of significant social disadvantage entering primary school with impoverished language skills. These children are not routinely referred to speech and language therapy services and therefore education practitioners in schools deliver intervention to facilitate…
