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…

The simple view of reading posits that reading comprehension can be decomposed into a print-specific component (concerning decoding and sight word reading) and a language comprehension component (concerning verbal and metalinguistic skills not related to print). One might properly consider lexical skills, indexed by vocabulary measures, part of…

High opportunities to respond (OTR) have been touted as being a key factor in a popular and effective drill procedure called incremental rehearsal (IR). However, IR has also been criticized because it takes more instructional time than other drill procedures and can be less time efficient. The current study compared the effectiveness and…

We evaluated the effects of student characteristics (sight word reading efficiency, phonological decoding, verbal knowledge, level of reading ability, grade, gender) and text features (passage difficulty, length, genre, and language and discourse attributes) on the oral reading fluency of a sample of middle-school students in Grades 6-8 (N =…

This study evaluated the effectiveness of high school tutors' implementation of "Great Leaps Reading" (Campbell, 1998), a reading fluency supplementary instructional program. The program consists of three sections: phonics, sight word phrases, and story passages. Daily 15-minute tutoring sessions involved repeated 1-minute timings of…

A sample of 141 Canadian children in grades 3 through 6 wrote to dictation 24 short sentences sampling 90 lexical items representing 10 inflectional morphological categories to study their relation to the written spelling of 40 sight words. The children were encouraged in 3, 30-minute teaching sessions to use multiple strategies of retrieval,…
