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.…

This exploratory study identified underlying skill and ability differences among subgroups of adolescent and young adult struggling readers (N = 290) overall and in relation to a fluency-based instructional grouping method. We used principal axis factoring of participants' scores on 18 measures of reading-related skills and abilities identified in…

This article presents findings of an efficacy trial examining the effect of a multitiered instruction and intervention model on first grade at-risk students' reading outcomes. Schools (N = 16) were randomly assigned to the treatment or control condition. In the fall of Grade 1, students were assigned to an instructional tier on the basis of…

The purpose of this study was to examine the relation between the ability to quickly acquire initial mental graphemic representations (MGRs) in kindergarten and fourth grade literacy skills in children with typical language (TL) and children with language impairment (LI). The study is a longitudinal extension of a study conducted by Wolter and…

This study is part of a broader project aimed at developing cognitive and neurocognitive profiles of adolescent and young adult readers whose educational and occupational prospects are constrained by their limited literacy skills. We explore the relationships among reading-related abilities in participants ages 16 to 24 years spanning a wide range…

The importance of word decoding in accounting for individual differences in reading comprehension is discussed. Research on individual differences in the cognitive processes that mediate word decoding is reviewed. (Author)

Naming speed skills of 45 dyslexic children (mean ages=8, 13, and 17) and slow learning children (mean age=10) were compared with those of normally achieving children. Results indicated that children with dyslexia and slow learners have persistent and severe problems in naming speed for all stimuli, regardless of whether the stimulus requires…

This investigation (with 30 normal students and 30 students with reading disabilities, ages 7-15) examined the relationship between intelligence and phonological coding when ability was defined according to the Planning, Attention, Simultaneous, Successive (PASS) cognitive processing model. Findings indicate that phonological problems may not be…

A sample of 133 Spanish children (ages 8 to 13) was classified by IQ and reading level and given a lexical processing task. The study found that IQ did not explain differences between learning-disabled (LD) or nondisabled (NLD) children in lexical processing. Lexical and sublexical parameters had a greater influence on LD students than NLD…

The PASS Remedial Program (PREP), a word reading program which focuses on 4 major cognitive processes (planning, attention, simultaneous, and successive processing) was evaluated with 51 grade-4 children with decoding difficulties. The "global process" and curriculum-related "bridging" program components were separately and…

A major focus in reading difficulty is lack of automaticity in decoding, which overloads the attentional system, leads to the use of small, meaningless visual processing units such as the individual letter, places heavy demands on short-term memory, and interferes with comprehension. Techniques for diagnosis and remediation are noted. (Author/JW)

Elementary children (n=112) comprising average IQ, high IQ, dyslexic, and normal readers were administered measures of planning, attention-arousal, simultaneous and successive processing, phonemic segmentation, and nonverbal IQ. Cognitive tasks differentiating dyslexic from normal readers were the successive processing tasks and two tasks of…

This study investigated specific processing strengths and weaknesses among 75 readers, ages 6-10, with no oral language deficits. Unsuccessful readers of different ages showed similar information processing patterns, and differed from successful first-grade readers on short-term auditory/working memory and decoding/encoding. Three potential…

The literature on individual differences in cognitive processes that operate at the text level is reviewed. Poor readers display comprehension deficits independent of word-decoding skill, due to deficient syntactic abilities and to more general metacognitive strategies. The general conclusions from this review and from Part One (ED 150 706) are…
