Discrimination of reversible mirrored letters (e.g., d and b) poses a challenge when learning to read as it requires overcoming "mirror invariance," an evolutionary-old perceptual tendency of processing mirror images as equivalent. The present study investigated "when," in reading development, mirror-image discrimination…

As children learn to read, they become sensitive to context-dependent vowel pronunciations in words, considered a form of statistical learning. The work of Treiman and colleagues demonstrated that readers' vowel pronunciations depend on the consonantal context in which the vowel occurs and reading experience. Using explanatory item-response models…

This in-brief technical report documents the results from two different analytic approaches for examining the reliability of the slope for easyCBM® reading measures in Grades K-8. Results varied by grade, assessment measure, and the analytic approach. Results patterns are discussed.

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),…

This study investigates the English spelling of students in grades 2 through 8 in Mainland China. A review of spelling and cross-linguistic research in spelling is presented. The orthographic development of 273 students was assessed "with validated spelling inventories" (Sterbinsky, 2007) to sample developmental features across three…

Two longitudinal studies of word reading, spelling, and reading comprehension identified commonalities and differences in morphophonemic orthographies--French (Study 1, n = 1,313) or English (Study 2, n = 114) in early childhood (Grade 2)and middle childhood (Grade 5). For French and English, statistically significant concurrent relationships…

Recent studies have emphasized that developmental dyslexia is a multiple-deficit disorder, in contrast to the traditional single-deficit view. In this context, cognitive profiling of children with dyslexia may be a relevant contribution to this unresolved discussion. The aim of this study was to profile 36 Portuguese children with dyslexia from…

Vocabulary learning is central to reading ability and academic achievement. Vocabulary researchers and educators have viewed its essence as a process of associating the pronunciations and meanings of words in memory, and they have paid little attention to the contribution that spellings might make to vocabulary learning. We review theory and…

This technical report presents an overview of a reading assessment used by a large school district in the Pacific Northwest. It provides sufficient background information to enable those unfamiliar with the assessment to understand the various subtests that comprise it as well as its development and application in the district for making…
