Swanson, H. Lee – Journal of Learning Disabilities, 2012
This article reviews the results of a meta-analysis of the experimental published literature that compares the academic, cognitive, and behavioral performance of adults with reading disabilities (RD) with average achieving adult readers. The meta-analysis shows that deficits independent of the classification measures emerged for adults with RD on…

Swanson, H. Lee – Journal of Learning Disabilities, 2012
A meta-analysis by Tran, Sanchez, Arellano, and Swanson (2011) of the published RTI literature found that the magnitude of effect size (ES) between responders and low responders at posttest was significantly moderated by the pretest ES and the type of dependent measure administered, whereas no significant moderating effects were found in the mixed…

Swanson, H. Lee – Journal of Educational Psychology, 2011
The role of working memory (WM) in children's growth in mathematical problem solving was examined in a longitudinal study of children (N = 127). A battery of tests was administered that assessed problem solving, achievement, WM, and cognitive processing (inhibition, speed, phonological coding) in Grade 1 children, with follow-up testing in Grades…

Swanson, H. Lee – Journal of Learning Disabilities, 2011
This longitudinal study assessed (a) whether performance changes in working memory (WM) as a function of dynamic testing were related to growth in reading comprehension and (b) whether WM performance among subgroups of children with reading disabilities (RD; children with RD only, children with both reading and arithmetic deficits, and low verbal…

Swanson, H. Lee – Intelligence, 2011
This study examined whether children's growth on measures of fluid (Raven Colored Progressive Matrices) and crystallized (reading and math achievement) intelligence was attributable to domain-specific or domain-general functions of working memory (WM). A sample of 290 elementary school children was tested on measures of intelligence across three…

Jerman, Olga; Reynolds, Chandra; Swanson, H. Lee – Learning Disability Quarterly, 2012
The present study investigated whether (a) growth patterns related to cognitive processing (working memory, updating, inhibition) differed in subgroups of children with reading disabilities (RD) and (b) growth in working memory (executive processing) predicted growth in other cognitive areas, such as reading and math. Seventy-three children (ages…

Swanson, H. Lee – Journal of Educational Psychology, 2008
This study explored the contribution of the phonological and executive working memory (WM) systems to 205 (102 girls, 103 boys, 6 to 9 years old) elementary school children's fluid and crystallized intelligence. The results show that (a) a 3-factor structure (phonological short-term memory [STM], visual-spatial WM, and verbal WM) was comparable…

Johnson, Deanne Emilie Dukleth; Swanson, H. Lee – Journal of Psychoeducational Assessment, 2011
The purpose of this quasi-experimental study was to compare the cognitive performance of 11-to 14-year-old children with reading disabilities as a function of high (greater than 85 reading standard score) and low (less than 85 reading standard score) response to intervention. Students were divided into high responders, low responders, and…

Swanson, H. Lee; Lussier, Catherine; Orosco, Michael – Society for Research on Educational Effectiveness, 2011
Although current categories of learning disabilities include as specific disabilities calculation and mathematical problem solving [see IDEA reauthorization, 2004, Sec. 300.8(c)(10)], the majority of research focuses on calculation disabilities. Previous studies have shown, however, that deficits in word problem solving difficulties are persistent…

Swanson, H. Lee; O'Connor, Rollanda – Journal of Learning Disabilities, 2009
The authors investigated whether practice in reading fluency had a causal influence on the relationship between working memory (WM) and text comprehension for 155 students in Grades 2 and 4 who were poor or average readers. Dysfluent readers were randomly assigned to repeated reading or continuous reading practice conditions and compared with…

Zheng, Xinhua; Flynn, Lindsay J.; Swanson, H. Lee – Learning Disability Quarterly, 2013
This article provides a quantitative synthesis of the published literature on word problem solving intervention studies for children with math disabilities (MD). Seven group and eight single-subject design studies met inclusion criteria. Mean effect sizes ("ES"s) for solution accuracy for group design studies were 0.95 (SE = 0.19) for children…

Orosco, Michael J.; Swanson, H. Lee; O'Connor, Rollanda; Lussier, Cathy – Journal of Special Education, 2013
English language learners (ELLs) struggle with solving word problems for a number of reasons beyond math procedures or calculation challenges. As a result, ELLs may not only need math support but also reading and linguistic support. The purpose of this study was to assess the effectiveness of a math comprehension strategy called Dynamic Strategic…

Swanson, H. Lee; Kehler, Pam; Jerman, Olga – Journal of Learning Disabilities, 2010
Two experiments investigated the effects of strategy knowledge and strategy training on the working memory (WM) performance in children (ages 10-11) with and without reading disabilities (RD). Experiment 1 examined the relationship between strategy knowledge (stability of strategy choices) and WM performance as a function of initial, gain (cued),…

Flynn, Lindsay J.; Zheng, Xinhua; Swanson, H. Lee – Learning Disabilities Research & Practice, 2012
This article synthesizes the experimental literature on reading interventions for upper elementary and middle school students identified with reading disabilities on norm-referenced reading measures. Ten studies (12 independent samples) yielded 70 effect sizes on norm-referenced reading measures with an aggregated mean of 0.41 (SE = 0.04) in favor…

Swanson, H. Lee; Orosco, Michael J.; Lussier, Cathy M. – Journal of Educational Psychology, 2012
This study explores the cognitive basis of reading disabilities (RDs) in Spanish-speaking children who are learning English as a second language. Children (N = 393) designated as English language learners (ELLs) or bilingual with and without RDs in Grades 1, 2, and 3 were administered a battery of cognitive (short-term memory, working memory,…
