Previous research has revealed conflicting results with regard to the role of the magnocellular visual system in reading and dyslexia. In order to investigate this further, the present study examined the relationship between performance on two magnocellular tasks (temporal gap detection and coherent motion), reading rate (oral and silent), and…

Studies investigating individual differences in reading ability often involve data sets containing a large number of collinear predictors and a small number of observations. In this article, we discuss the method of Random Forests and demonstrate its suitability for addressing the statistical concerns raised by such data sets. The method is…

The Occupation and Participation Approach to Reading Intervention (OPARI) is an intervention approach for children with reading difficulties that emphasizes reading as an important occupation of children. Part I presented the theoretical basis of the OPARI. Part II describes a pilot clinical application of the OPARI. Guided by Schkade and…

Approximately 15-20% of the U.S. population has been diagnosed with dyslexia. The theory of automaticity implies that automatic decoding precedes fluency in reading, leading to better comprehension. The "Reading from Scratch" program is designed to assist dyslexics improve their reading ability. Research questions for this case study…

In 2001 the No Child Left Behind Act (NCLB) mandated that U.S. public schools provide evidence-based practice for individuals with learning disabilities. However, it is unclear whether U.S. public schools have consistently adhered to this mandate. The purpose of this study was to provide preliminary evidence regarding whether U.S. public schools…

Over the past few decades, reading assessment has been pushed to the forefront of the national discussion about education. The most recent reauthorizations of the Elementary and Secondary Education Act (1994, 2001) made assessment a priority as administrators and teachers are attempting to meet increasing accountability standards, but measuring…

Does the choice of test for assessing reading comprehension influence the outcome of genetic analyses? A twin design compared two types of reading comprehension tests classified as primarily associated with word decoding (RC-D) or listening comprehension (RC-LC). For both types of tests, the overall genetic influence is high and nearly identical.…

Study of the language and literacy skills of individuals with Down syndrome (DS) has evolved over the past thirty years. Despite these advances, little research has explored the process of reading by incorporating an authentic text (i.e. storybook). This information is pertinent to assist in the understanding of language and literacy and the…

Comprehension tests are often used interchangeably, suggesting an implicit assumption that they are all measuring the same thing. We examine the validity of this assumption by comparing some of the most popular reading comprehension measures used in research and clinical practice in the United States: the Gray Oral Reading Test (GORT), the two…

The FRI and GORT tests are reviewed with attention to test rationales and purposes, test development, test administration, and making the purchase choice. Concludes that the FRI is the preferable test. (JK)
