Several studies have reported high comorbidity for reading disability (RD) and psychiatric disorders. The aim of this study was to investigate the comorbidity of subthreshold and full psychiatric disorders with RD while comparing subgroups based on age of RD recognition (early vs. late). We analyzed data from 130 children with RD and 82 typically…

The "Woodcock-Johnson III" Tests of Achievement grade norms versus age norms were examined in the calculation of discrepancy scores in 202 college students. Difference scores were calculated between the "Wechsler Adult Intelligence Scale-3rd Edition" Full Scale IQ and the "Woodcock-Johnson III" Total Achievement,…

In a 3-year longitudinal study, 471 children were classified, based on their performances on arithmetic tests in first and second grade, as having persistent arithmetic disabilities (AD), persistent low achieving (LA), persistent typical achieving, inconsistent arithmetic disabilities (DF1), or inconsistent low achieving in arithmetic. Significant…

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also…

Students (ages 6-10, n=144), grouped by age and reading ability, were administered tasks with a demonstrated relationship to reading. The concept of dyslexia was supported only for the older group, for whom dyslexia appeared to be either a phonological deficit or a developmental lag. (Author/DB)

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…

This study investigated early clinical differences between 27 children (ages 0-4) with pervasive developmental disorder not otherwise specified and 27 children with attention deficit disorder. Results revealed almost no differences between both groups with respect to pregnancy or birth complications and suggest that differences become more…

Thirteen teachers rated elementary students (n=30) with learning disabilities and low achievement as having significantly lower social competence and school adjustment than their achieving peers, but teacher ratings of junior high students did not discriminate among groups. Results support use of teacher ratings for initial screening of elementary…
