Pieters, Stefanie; Roeyers, Herbert; Rosseel, Yves; Van Waelvelde, Hilde; Desoete, Annemie – Journal of Learning Disabilities, 2015
A relationship between motor and mathematical skills has been shown by previous research. However, the question of whether subtypes can be differentiated within developmental coordination disorder (DCD) and/or mathematical learning disability (MLD) remains unresolved. In a sample of children with and without DCD and/or MLD, a data-driven…

Vrachimi-Souroulla, Andry; Panayiotou, Georgia; Kokkinos, Constantinos M.; Lamprianou, Iasonas – Educational Psychology, 2011
The study aimed to field-test a Greek version of the Wechsler Quicktest and to examine its psychometric properties. The Quicktest was individually administered to 208 students, aged 5-14 years, along with a reading test. Based on the Rasch analysis, data for the Quicktest subtests showed acceptable fit to the model. Also, correlations were found…

What Is the Role of Intelligence in the Identification of Specific Learning Disabilities? Issues and Clarifications
Peer reviewed Peer reviewed

Gresham, Frank M.; Vellutino, Frank R. – Learning Disabilities Research & Practice, 2010
A fundamental assumption in the identification of specific learning disabilities (SLD) has been that the presence of a severe discrepancy between ability and academic achievement is a valid marker for the presence of a SLD. This assumption is based on the notion that discrepant low achievers constitute a unique group of children who are different…

A Comparison Between WISC-III and WISC-R Scores for Learning Disabilities Reevaluations.
Peer reviewed Peer reviewed
Lyon, Mark A. – Journal of Learning Disabilities, 1995
This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…
