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…

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…

This experimental study reports findings on the effects from a year-long reading intervention providing daily 50-min sessions to middle school students with identified learning disabilities (n = 65) compared with similar students who did not receive the reading intervention (n = 55). All students continued to receive their special education…
