It is now possible to create individual-specific genetic scores, called genome-wide polygenic scores (GPS). We used a GPS for years of education ("EduYears") to predict reading performance assessed at UK National Curriculum Key Stages 1 (age 7), 2 (age 12) and 3 (age 14) and on reading tests administered at ages 7 and 12 in a UK sample…

Social science research often uses educational qualification as a signifier for characteristics such as abilities, earnings potential, and civic participation in adulthood. This study focused on two types of adult literacy students who were native speakers of English and identified words at the 3rd to 5th grade levels but differed in one key…

The study examines comprehension after oral and silent reading in elementary- and middle-school students. It investigates whether and when one mode is superior to the other for comprehension as children develop, independent of reading ability levels. One hundred and seventy three children in first through seventh grades orally and silently read…

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.…

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…

Educable mentally retarded (EMR) children were presented an item selection task to assess their sensitivity to orthographic structure in printed English words. Analyses of performance indicated that EMR children do acquire implicit knowledge of orthographic rules and that this ability is related to the development of reading skills. (Author)

Develops an alternative analysis to the Peabody Individual Achievement Tests' authors' suggested use of a pairwise comparison system to determine when one academic area is significantly different from another. Suggests determining academic strengths and weaknesses relative to a child's average performance on the entire test. (Author/JAC)
