The purpose of the present study was to explain the moderating role of rapid automatized naming (RAN) in word reading with a cusp catastrophe model. We hypothesized that increases in RAN performance speed beyond a critical point would be associated with the disruption in word reading, consistent with a "generic shutdown" hypothesis.…

The purpose of the present study was to examine the hypothesis that a nonlinear relationship exists between a performance-classroom climate and the reading achievement of adolescent students with learning disabilities (LD). Participants were 62 students with LD (Grades 5-9) from public elementary schools in northern Greece. Classroom climate was…

The longitudinal prediction of reading problems from fourth grade to sixth grade was investigated with a sample of 173 students. Reading problems at the end of sixth grade were defined by significantly below average performance (= 15th percentile) on reading factors defining word reading, fluency, and reading comprehension. Sixth grade poor reader…

The purpose of the present studies was to provide the means to create brief versions of instruments that can aid the diagnosis and classification of students with learning disabilities and comorbid disorders (e.g., attention-deficit/hyperactivity disorder). A sample of 1,108 students with and without a diagnosis of learning disabilities took part…

Despite the emerging evidence base on response to intervention, there is limited research regarding how to effectively use progress-monitoring data to adjust instruction for students in Tier 2 intervention. In this study, we analyzed extant data from a series of randomized experimental studies of a kindergarten supplemental reading intervention to…

This exploratory study examined the influences of student, teacher, and setting characteristics on kindergarteners' early reading outcomes and investigated whether those relations were moderated by type of intervention. Participants included 206 kindergarteners identified as at risk for reading difficulties and randomly assigned to one of two…

The reading achievement of students with learning disabilities (N=24) who received DISTAR instruction was compared to that of similar students using basal reader materials. The overall reading scores were not significantly different following one and two years of instruction, although DISTAR students had somewhat better word attack skills. (DB)

This study, with 38 9-year-old poor readers and 40 reading age-matched normally achieving readers, examined qualitative differences in poor readers relative to normally achieving readers of the same reading level. Results suggest that poor readers have worse grapheme phoneme conversion skills and greater reluctance to relinquish the lexical route…

Experimental phonological synthesis (sound blending) and analysis (rhyme detection) tasks were administered to children (n=76) preceding kindergarten entry. Measures of beginning reading were administered after kindergarten, first grade, and second grade. The sound blending task was significantly related to most interim and outcome measures. The…

Three studies investigated the effectiveness of the Computer Assisted Reading Diagnosis, a diagnostic system based on "rauding" theory (a collection of theories, constructs, and equations developed to describe, explain, predict and control the ability to comprehend relatively easy sentences) and a causal model of reading achievement.…

Twenty-seven boys (ages 8-11) with hyperactive disorder and 28 boys with hyperactive-aggressive disorder were administered methylphenidate. No significant results were found for the hyperactive disorder group in either reading recognition or comprehension. The hyperactive-aggressive group improved in reading comprehension, with no effect resulting…

This study measured the effects of increasing levels of intervention in reading for a cohort of children in Grades K through 3 to determine whether the severity of reading disability (RD) could be significantly reduced in the catchment schools. Tier 1 consisted of professional development for teachers of reading. The focus of this study is on…
