Swanson, H. Lee; Trahan, Marcy – Learning Disability Quarterly, 1990
Thirty-five learning-disabled readers (mean age 10) and 43 controls were compared on a sentence span task and on recall of everyday features, consequential events, and misleading information. Results indicated that subjects were deficient on working memory and naturalistic measures, but their naturalistic memory deficits did not appear to relate…

Swanson, H. Lee – Journal of Experimental Child Psychology, 2003
Examined whether age-related working memory deficits in learning disabled (LD) readers across four age groups (7, 10, 13, and 20) reflected retrieval efficiency or storage capacity problems. Found that LD readers' working memory performance was inferior to skilled readers' on verbal and visual-spatial working memory tasks across all ages.…

Wilson, Kathleen M.; Swanson, H. Lee – Journal of Learning Disabilities, 2001
The relationship between verbal and visual-spatial working memory and mathematical computation skill was examined in 98 children and adults with and without mathematical disabilities. A hierarchical regression analysis, when partialing for reading ability, age, and gender influences, showed mathematical computation was better predicted by verbal…

Swanson, H. Lee – Developmental Psychology, 1999
Compared verbal and visuo-spatial working memory (WM) performance under initial, gain, and maintenance conditions for nine age groups from 6 to 57 years to determine if differences were attributable to specific or general processing functions. Found support for a general-capacity explanation of age-related differences, reflecting demands placed on…

Keeler, Marsha L.; Swanson, H. Lee – Journal of Learning Disabilities, 2001
A study investigated the relationship between working memory (WM), declarative strategy knowledge, and math achievement in 111 children with and without mathematical disabilities (MD). Results found verbal and visual-spatial WM, stable verbal strategy choices, and expert strategy choices related to visual-spatial processing all contributed…

Swanson, H. Lee – Journal of School Psychology, 1985
Attempted to increase the occurrence of sexual-social interactions of emotionally disturbed adolescents. Results indicate that, regardless of sex, group contingencies are more effective than individual contingencies in increasing positive sexual-social interactions. Results inferred that emotionally disturbed adolescents' social interactions…

Swanson, H. Lee; Trahan, Marcille F. – Learning Disabilities Research and Practice, 1992
Learning-disabled and average readers (n=120) from grades four through six completed comprehension questions under one of four treatment conditions. Results indicated that computer-mediated text was no better than off-line conditions in improving learning-disabled readers' comprehension. Attribution and metacognitive sophistication were…

Swanson, H. Lee – Journal of Learning Disabilities, 1977
Short-term memory recognition scores and strategies were investigated in 10 learning disabled and 10 educable mentally retarded (EMR) students (10-13 years old). (Author/CL)

Simmerman, Susan; Swanson, H. Lee – Journal of Learning Disabilities, 2001
A review of 913 studies involving students with learning disabilities found treatment outcomes were significantly affected by the following violations: teacher effects, establishing criterion levels of instructional performance, reliance on experimental measures, using different pretest and posttest measures, using a sample heterogeneous in age,…
