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.

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…

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…

We report the results of a test-retest and alternate form reliability study of grade 1, 3, 5, and 8 reading measures from the easyCBM assessment system. Approximately 50 students in each grade participated in the study. In Grade 1, we studied the following measures: Phoneme Segmenting, Letter Sounds, Letter Names, Word Reading Fluency, and Passage…

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…
