This study examined longitudinally the double-deficit hypothesis in Greek, an orthographically consistent language, following a group of children from kindergarten to Grade 2. Four groups were formed on the basis of two composite scores of phonological and naming-speed criterion measures: a double-deficit group (DD; n = 17), a phonological deficit…

The present study analyzed data from the Jyvaskyla Longitudinal Study of Dyslexia to investigate the factors to which mothers of children with and without familial risk for dyslexia attribute the causes of their first-grade children's reading achievement. Mothers' causal attributions were assessed three times during their children's first school…

Children's number sense in kindergarten was used to predict their calculation fluency in second grade (N = 198). Using block entry regression, usual predictors of age, reading, memory, and verbal and spatial cognition were entered in the first block and number sense measures were added in the second block. Number sense measures contributed a…

This study attempted to determine whether children with the combined subtype of attention-deficit/hyperactivity disorder (ADHD) have impairments in cognitive functioning and motor skills. The specific effect of the comorbidity of learning disabilities (LD) was also investigated. A battery of cognitive tests was administered to 26 children with a…

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…

The study of 813 learning disabled children (ages 6-11) with test-retest data (after three years) on 224 children found the children to suffer a progressive deterioration in verbal ability whereas their nonverbal ability showed an increase in the earlier years, leveling off thereafter. (Author/DB)

Forty-three elementary students with learning disabilities in mathematics were administered a variety of measures to examine the relationship between selected language and visuospatial skills and mathematic achievement. (Author/DLS)

The EEG biofeedback training produced baseline effects in the presumably dysfunctional left hemisphere and had an impact on arousal in task, suggesting remedial potential for the possible hemispheric arousal deficts in learning disabilities. Training the right hemisphere toward higher arousal and the left hemisphere toward lower arousal resulted…

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)

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…

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…

The relationship between verbal and visual-spatial working memory and mathematical computation skill was examined in 98 children and adults with and without mathematical disabilities. A hierarchical regression analysis, when partialing for reading ability, age, and gender influences, showed mathematical computation was better predicted by verbal…

The effects of visual paradigmatic organization on verbal recall among language/learning disabled children was studied with 20 such children (age: 8-13 years), who were screened to eliminate visual memory deficits. (Author)
