Purpose: To assess strengths and weaknesses of the reading level (RL) match approach and its potential to generate insights regarding the cognitive foundations of reading ability and disability. Method: We applied RL-match design to a sample of 2nd-6th graders reading a consistent orthography, Russian, using an "extreme phenotype"…

Rau, Anne K.; Moll, Kristina; Moeller, Korbinian; Huber, Stefan; Snowling, Margaret J.; Landerl, Karin – Scientific Studies of Reading, 2016
The current study compared eye fixation patterns during word and sentence processing in a consistent and an inconsistent alphabetic orthography. German and English children as well as adults matched on word reading ability read matched sentences while their eye fixation behavior was recorded. Results indicated that German children read in a more…

Selzam, Saskia; Dale, Philip S.; Wagner, Richard K.; DeFries, John C.; Cederlöf, Martin; O'Reilly, Paul F.; Krapohl, Eva; Plomin, Robert – Scientific Studies of Reading, 2017
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…

Steacy, Laura M.; Kirby, John R.; Parrila, Rauno; Compton, Donald L. – Scientific Studies of Reading, 2014
The Double Deficit Hypothesis of dyslexia is one approach to classifying students with reading disabilities. The theory offers four distinct groups of readers: (a) average readers, (b) students with phonological deficits, (c) students with naming speed deficits, and (d) students with double deficits: those having both (b) and (c). This study…

Betjemann, Rebecca S.; Keenan, Janice M.; Olson, Richard K.; DeFries, John C. – Scientific Studies of Reading, 2011
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.…

Olson, Richard K. – Scientific Studies of Reading, 2004
Environment and Genes are often found in the titles of my articles, but this is the first and most likely the last of my titles to include SSSR. This article is based on my presidential address at the 10th annual meeting of the Society for the Scientific Study of Reading (SSSR) in Boulder, Colorado (2003), so I begin with some reflection on the…

Misra, Maya; Katzir, Tamar; Wolf, Maryanne; Poldrack, Russell A. – Scientific Studies of Reading, 2004
The majority of children and adults with reading disabilities exhibit pronounced difficulties on naming-speed measures such as tests of rapid automatized naming (RAN). RAN tasks require speeded naming of serially presented stimuli and share key characteristics with reading, but different versions of the RAN task vary in their sensitivity: The RAN…
