Understanding how the etiology of print awareness and phonological awareness are related to the etiology of decoding can provide insights into the development of word reading. To address this issue, we examined the degree of overlap among etiological influences of prereading skills in 1,252 twin pairs in kindergarten. Genetic, shared…

Too many children fail to learn how to read proficiently with serious consequences for their overall well-being and long-term success in school. This may be because providing effective instruction is more complex than many of the current models of reading instruction portray; there are Child Characteristic x Instruction (CXI) interactions. Here we…

The role of student attention for predicting kindergarten word reading was investigated among 432 students. Using "Strengths and Weaknesses of ADHD Symptoms and Normal Behavior Rating Scale" behavior rating scores, the authors conducted an exploratory factor analysis, which yielded three distinct factors that reflected selective…

This experimental study was designed to validate a short-term supplemental reading intervention for at-risk first-grade children. Although substantial research on long-term supplemental reading interventions exists, less is known about short-term interventions. Thirty first-grade children were randomly assigned to intervention or control…

Background: Studies have suggested genetic and environmental influences on overall level of early reading whereas the larger reading literature has shown environmental influences on the rate of growth of early reading skills. This study is the first to examine the genetic and environmental influences on both initial level of performance and rate…

Many children fail to reach proficient levels in reading only because they do not receive the amount and type of instruction they need (Foorman, Francis, Fletcher, Schatschneider, & Mehta, 1998; Morrison, Bachman, & Connor, 2005 2005; Vellutino, Scanlon, Sipay, Small, Pratt, Chen, & Denckla, 1996). However, providing effective…

The purpose of this study was to identify and evaluate a universal screening battery for reading that is appropriate for older elementary students in a response to intervention model. Multiple measures of reading and reading correlates were administered to 230 fourth-grade children. Teachers rated children's reading skills, academic competence,…

Evidence from intervention studies, quantitative genetic and molecular genetic studies suggests that genetic, and to a lesser extent, shared environmental influences are important to the development of reading and related cognitive skills. The Northeast-Northwest Collaborative Adoption Projects (N2CAP) is a sample of 241 adoptive families,…

The current study involved 281 early-school-age twin pairs (118 monozygotic, 163 same-sex dizygotic) participating in the ongoing Western Reserve Reading Project (S. A. Petrill, K. Deater-Deckard, L. A. Thompson, & C. Schatschneider, 2006). Twins were tested in their homes by separate examiners on a battery of reading-related skills including…

The purpose of this research was to investigate the effectiveness of a tutoring intervention provided by community tutors to kindergarten students at risk for reading difficulties. The 73 students were randomly assigned to 1 of 3 conditions: (a) tutoring 4 days a week, (b) tutoring 2 days a week, or (c) a control condition that provided…

The present study combined parallel data from the Northeast-Northwest Collaborative Adoption Projects (N2CAP) and the Western Reserve Reading Project (WRRP) to examine sibling similarity and quantitative genetic model estimates for measures of reading skills in 272 school-age sibling pairs from three family types (monozygotic twins, dizygotic…

There is considerable focus in public policy on screening children for reading difficulties. Sixty years of research have not resolved questions of what constructs assessed in kindergarten best predict subsequent reading outcomes. This study assessed the relative importance of multiple measures obtained in a kindergarten sample for the prediction…

To identify factors that contribute to development of phonological awareness, investigated longitudinal relationships among child background factors, structural oral language, and phonological awareness in children in kindergarten through Grade 2, and a subsample who were nonreaders in kindergarten. Suggests general oral language may contribute to…

We examined models of individual change and correlates of change in the growth of reading skills in a sample of 40 children from kindergarten through third grade. A broad range of correlates was examined and included family literacy, oral language, emergent reading, intelligence, spelling, and demographic variables. Individual growth curve…
