Two studies involving 215 subjects tested the hypothesis that orthographic coding bypasses phonological coding after the early stages of reading or spelling. It was found that nondyslexics continue to develop phonological coding skill until adulthood and rely on it for reading and spelling to a significantly greater extent than do dyslexics.…

Normal students (N=65) in fourth, sixth, and eighth grades were compared to 17 learning-disabled ninth graders on learning derivational morphology and spelling derived forms. Disabled students' knowledge of derivational morphology was equivalent to that of normal sixth graders, but spelling of derived forms was equivalent to that of fourth…

Fourteen poor-reading college students were assigned to a dyslexia group or a nonspecific reading-disabled group based on intelligence quotient (IQ). The groups were compared to controls on cognitive and reading-related skills. Results showed that poor decoding skill characterized the dyslexic reader, whereas the nondyslexic poor reader displayed…

Reading disability subtypes were determined in 50 neurologically impaired students (ages 11-19), with and without reading disabilities. Subtypes found primarily in the reading-disabled sample were anomic-language disorder, dysphonetic and mixed dysphonetic-dyseidetic, oral reading deficit, intermodal association deficit, and sequential relations…

Reading-disabled children (n=36) in grades four through eight were matched for reading comprehension and placed into two groups based on listening comprehension. Poor readers with normal listening comprehension had average or above intelligence quotients, conforming to the traditional definition of dyslexia and contrasting with poor readers with…

A model for understanding reading, containing three components (orthographic/phonological, morphological, and sentence and paragraph comprehension) was tested with 298 preadolescent readers. Maximum likelihood analyses showed that the model provides a good fit for the grade 4 data, a reasonable fit for grade 5, but was less unambiguous for grade…

Data analysis of 134 twin pairs from the Colorado Reading Project found that approximately 40 percent of the deficit observed in disabled readers is because of genetic factors, 35 percent because of environmental influences shared by twin pairs, and 25 percent because of environmental factors unique to the individual and/or error variance.…

Forty normal readers and 50 dyslexic children (age 9-14) were matched on reading level and intelligence quotient and tested. Analysis revealed 3 major subgroups: specific deficit in phonological processing of print (52 percent), deficits in processing both the phonological and orthographic features of printed words (24 percent), and phonological…

A group of 30 nonreading kindergarten children who received 7 weeks of instruction in phoneme segmentation and letter names/sounds were assessed on segmentation and reading measures. They outperformed a language activities group, which received instruction in letter names/sounds and additional language activities, and a group receiving no…

Data from a 10-year study involving over 1,000 dyslexics, age 7-15, went into the development of the Alphabetic Phonics curriculum. One aspect of the curriculum, the Syllable Division Formulas, is described. It emphasizes scientific, automatic, multisensory procedures for dividing longer words into easily read syllables.

Two experiments sought to determine the orthographic and phonological factors in derived morphology that affected the reading and spelling performance of 75 intermediate-grade poor readers. Subgroups of poor readers used different mechanisms in producing derived or base forms of words according to the complexity of the orthographic and/or…

Writing samples of 295 primary school children improved in productivity, syntax, and level of abstraction from grade one through three. The writing of learning-disabled children who were matched with average reading ability primary-school children indicated no significant differences in productivity, but problems in syntax (especially morphology),…

A theoretical framework is presented for understanding difficulties in foreign language learning, based upon a linguistic coding model that hypothesizes deficits in phonological, syntactic, and semantic information processing. Incidence of linguistic coding problems in 22 college-enrolled or college-bound students who petitioned to have the…

The prereading and reading performance of 370 predominantly Hispanic, bilingual school children was followed for 6 years. A 5-test Screening Index misclassified many failing readers but accurately identified children who eventually read well. Predictor tests administered at beginning of first grade showed significant correlations with reading at…

Delinquents (n=116) with reading disabilities were given daily multisensory (Orton/Gillingham approach) remedial reading instruction or regular reading instruction. One year after release, the treatment group had made significantly greater growth in reading and had a significantly lower rate of recidivism. (Author/DB)
