Direct linkTreiman, Rebecca; Hulslander, Jacqueline; Olson, Richard K.; Willcutt, Erik G.; Byrne, Brian; Kessler, Brett – Scientific Studies of Reading, 2019
We examined the predictive value of early spelling for later reading performance by analyzing data from 970 U.S. children whose spelling was assessed in the summer following the completion of kindergarten (M age = 6 years; 3 months). The word reading performance of most of the children was then tested after the completion of Grade 1 (age 7;5),…

Fujisawa, Keiko K.; Wadsworth, Sally J.; Kakihana, Shinichiro; Olson, Richard K.; DeFries, John C.; Byrne, Brian; Ando, Juko – Learning and Individual Differences, 2013
This first Japanese twin study of early literacy development investigated the extent to which genetic and environmental factors influence individual differences in prereading skills in 238 pairs of twins at 42 months of age. Twin pairs were individually tested on measures of phonological awareness, "kana" letter name/sound knowledge,…

Hulslander, Jacqueline; Olson, Richard K.; Willcutt, Erik G.; Wadsworth, Sally J. – Scientific Studies of Reading, 2010
Individual differences in word recognition, spelling, and reading comprehension for 324 children at a mean age of 16 were predicted from their reading-related skills (phoneme awareness, phonological decoding, rapid naming, and IQ) at a mean age of 10 years, after controlling the predictors for the autoregressive effects of the correlated reading…
