The strong differences in manifestation, prevalence, and incidence in dyslexia across languages invite studies in specific writing systems. In particular, the question of the role played by emergent literacy in opaque and transparent writing systems remains a fraught one. This research project tested, through a 4-year prospective cohort study, an…

Researchers investigated the self-concept profiles of twice-exceptional students in relationship to their cognitive ability and participation in educational services. All subjects (N = 64) had high ability (IQ score at or above the 90th percentile) and were diagnosed with either an autism spectrum disorder (ASD; n = 53) or specific learning…

We examined the double-deficit hypothesis in Finnish. One hundred five Finnish children with high familial risk for dyslexia and 90 children with low family risk were followed from the age of 3 1/2 years until Grade 3. Children's phonological awareness, rapid naming speed, text reading, and spelling were assessed. A deficit in rapid automatized…

Certain subtests of the WISC, ITPA, and Stanford-Binet are used as measures of analogical reasoning. Because several facts suggested that the form of analogy used on these subtests does not require subjects to engage in true analogical reasoning, the validity of these subtests as measures of analogical reasoning was investigated.

While the WISC and Bender-Gestalt are widely used for differential diagnosis, there is a need for empirically determined criteria for classification. Multivariate techniques seem especially promising in classification problems. This study determined the extent to which such an approach can classify children into rational, a priori categories of…

Relates gains in the reading, language, and mathematics achievement of 35 upper-elementary Ojibwa (Chippewa) children to their scores on certain subtests of the WISC-R and the Illinois Test of Psycholinguistic Abilities. Uses multiple regression analyses and cross-validation strategies. Contains 17 references and 7 statistical tables. (SV)
