Handwriting difficulties are frequently mentioned in descriptions of developmental coordination disorder (DCD). Recent studies have shown that children with DCD pause more and produce less text than typically developing (TD) peers. This temporal dysfluency indicates a lack of automaticity in handwriting production. One possible contributing factor…

The current study examined the development of two effects that have been found in single-digit multiplication errors: relatedness and distance. Typically achieving (TA) second, fourth, and sixth graders and adults, and sixth and eighth graders with a mathematics learning disability (MLD) performed a verification task. Relatedness was defined by a…

Recent studies have shown that children with mathematics difficulties (MD) have weaknesses in multiple areas of mathematics. Andersson, for example, recently found that children with MD perform significantly worse than other children on clock reading tasks. The present study builds on this recent finding and aims at a more profound understanding…

Errors in written multi-digit computation were investigated in children with math difficulties. Third- and fourth-grade children (n = 291) with coexisting math and reading difficulties, math difficulties, reading difficulties, or no learning difficulties were compared. A second analysis compared those with severe math learning difficulties, low…

Visuospatial working memory and its involvement in arithmetic were examined in two groups of 7- to 11-year-olds: one comprising children described by teachers as displaying symptoms of nonverbal learning difficulties (N = 21), the other a control group without learning disabilities (N = 21). The two groups were matched for verbal abilities, age,…

The adaptive use of approximate calculation was examined using a verification task with 18 third graders with mathematics learning disabilities, 22 typically achieving third graders, and 21 typically achieving second graders. Participants were asked to make true-false decisions on simple and complex addition problems while the distance between the…

Spelling error patterns of 30 disabled readers (grades 3 through 6) were compared to error patterns of 40 younger able readers (grades 1 through 3), and 37 able readers of the same age. Discriminant analyses indicated distinguishing patterns, primarily between the disabled readers and the older able readers. (Author/SEW)

Monitoring on some school-related tasks (editing, writing, spelling, and synonymy) was studied in learning disabled and normal adolescents. (Author)

Comparison of 30 learning disabled (LD) children, ages 7 to 13, and controls on a computerized test of attentional skills indicated LD subjects committed more omission errors and responded at a slower rate but did not differ from the controls on commission errors, suggesting inefficient allocation of processing resources rather than attentional…

The study investigated word-finding skills in 30 learning disabled (LD) boys (ages 8-to-11-years). Ss were administered measures designed to explore word-finding ability in three stimulus contexts for high- and low-frequency words.

A study of Hans Christian Andersen's diaries from age 20 to age 70 found that his mean error spelling percentages are equal to contemporaries, but between 2 and 15 times lower than individuals with dyslexia. A structural analysis indicates that the proportion of plausible/implausible errors match those of normal achievers. (Contains references.)…

Twelve secondary students with learning disabilities read aloud from a text after previewing the passage under one of three conditions. Results showed significant decreases in error rates under slow-rate listening previewing and silent previewing and showed that slow-rate listening previewing resulted in fewer errors per minute than did fast-rate…

The study analyzed oral reading miscues in both first and second reading languages of 20 Hispanic successful and 20 learning disabled readers in the intermediate grades. Significant differences were found for English reading in grammatical relationships, comprehension, and grammatical function. (Author/DB)

To examine the association between reversal errors and neurological disorders, 409 first graders were asked to name the letters of the lowercase alphabet presented in fixed, nonalphabetical order. (Author)

A study of the writing disorders shown by students (n=260) taught by different methods of reading and writing found that pupils learning by a global-natural method make errors related more to reproductive aspects of information, whereas children taught by the phonic and syllabic methods made more errors of meaning.
