Ninety-three children (ages 10-12) were compared on phonological and visuospatial abilities. Children with a reading disability performed worse than nondisabled children on many visual and eye movement tasks. Sixty-eight percent of the variance in reading ability could be predicted by combining visual and phonological scores in a multiple…

Factors associated with arithmetic-and-reading disability and specific arithmetic disability were investigated in over 850 representative New Zealand children. Reverse patterns of strengths and weaknesses with regard to verbal and nonverbal skills for these two types of arithmetic disability were found for boys but not for girls. (Author/DB)

This study, with 93 third grade poor readers, 54 fifth grade poor readers (with and without reading/IQ discrepancies), and 147 nondisabled first graders, found poor readers significantly more impaired than the matched first graders on all measures of nonword reading thus supporting the hypothesis of a deficit in nonword reading skills not…

Sixty students with specific learning disabilities in either reading and spelling (Group R-S) or arithmetic (Group A), as scored by the Woodcock-Johnson Psycho-Educational Battery, were compared. Results (measured by the Wechsler Intelligence Scale for Children-Third Edition) showed weaker nonverbal skills and more counseling among Group A…

Four studies involving 45 subjects found that children (ages 9-14) with nonverbal learning disabilities syndrome exhibited specific patterns of impairment in mechanical arithmetic and in psychosocial functioning, whereas children with poor performance in reading and spelling exhibited patterns of academic deficits (including arithmetic), but not…

This article integrates the literature on intelligence and achievement outcomes in boys with Klinefelter syndrome (KS). It reports results of a study following 36 boys with KS and 33 sibling controls. Boys with KS demonstrated verbal cognitive deficits and significant underachievement in reading, spelling, and arithmetic, which increased with age.…

Comparison of eight-year-old children with attention deficit hyperactivity disorder (ADHD) (n=21), learning disorder (LD) (n=12), or both (n=27) on neuropsychological measures found that ADHD children were impaired in control and inhibition of impulses; children with LD in phonological awareness, verbal memory span, storytelling, and verbal IQ;…

The ability to identify six facial expressions was studied in 48 nondisabled children and 76 children with learning disabilities (LD) ages 9 through 12. Overall, the nondisabled group had better interpretive ability. Among LD children, those with verbal deficits had better ability than either those with nonverbal deficits and or those with both…

This study examined relationships among lens color, visual grating, visual detection task performance, and peripheral retinal brightness thresholds among four adults and four children with reading disabilities and age-matched controls. Subjects with reading disabilities displayed significantly lower contrast sensitivity when tested with sine-wave…

The study provides descriptive data on use of the Woodcock-Johnson Tests of Cognitive Ability with 39 adults with closed head injury. Correlational analyses indicated significant relationships between coma duration and performance on the Perceptual Speed and Memory clusters of the test. Time since injury did not correlate with test results.…

Eighty-two elementary school children with attention deficit disorder (ADD) and dyslexia made more errors than 83 normally reading children with ADD on a test of rhyme and alliteration. A subgroup of dyslexic children who were sensitive to rhyme and alliteration scored higher than other dyslexic children on a test of spatial ability. (Author/DB)

Children (N=20, age 9-12) with severe dyslexia were slower in counting from memory and naming alternating digits and letters than children with milder reading impairment. The children most disabled also had poorer phonological sensitivity, shorter digit spans, and lower verbal intelligence quotients. (Author/DB)

The study demonstrated that 36 male children (ages 7-10) with learning problems were characterized not by a restricted vocabulary as such (i.e., the variance common to both receptive and productive vocabulary measures) but by a hampered production of words (i.e., the variance common to both speed-of-naming and productive vocabulary measures.…

Examination of the relationship between educational attainment and long-lasting, bilateral otitis media with effusion (OME) in 270 Dutch children (ages 2 to 4) found that, at age 7, early bilateral OME affected spelling ability but not reading ability. Effects of treatment with ventilation tubes were not found. (DB)

This article presents evidence that initial and advanced reading abilities are predominantly mediated by the right and left cerebral hemispheres, respectively. Premature reliance on left hemisphere reading strategies or later failure to shift from earlier right hemisphere strategies are hypothesized as resulting in two different types of dyslexic…
