Evaluation of the relationship between hyperactivity and learning difficulties in 1,593 Australian elementary students indicated twice as many males as females with learning difficulties; 11% of the sample were hyperactive; 41% of the subjects with learning difficulties were also hyperactive; and 3.2% of all subjects had both hyperactivity and…

A study investigated whether higher prevalence of reading disabilities among boys is related to gender bias in the prediction of reading from IQ. Data from 1,139 New Zealand children (collected during ages 5-13) indicate a significant intercept bias. Boys' predicted reading scores were systematically overestimated, thereby inflating IQ-reading…

A study involving 11,804 British children (age 10) found that when specified criteria for dyslexia were used, 269 children qualified as dyslexic. These included 223 boys and 46 girls, for a ratio of 4.51 to 1. Difficulties in interpreting these data are discussed and a defense of the criteria is provided. (Author/CR)

This brief paper reports on a study of learning disabilities in students with deafness. The study attempted to first determine to what extent deficiencies in communication skills affect the screening of deaf students for learning disabilities and, second, to describe the phenomenon of learning disability in students with deafness. The research…

A study involving 145 Israeli mother-child dyads examined the contribution of a multidimensional model of risk factors in explaining adaptive functioning among kindergartners with mild developmental delays considered at risk for developing learning disorders. Results indicated a high fit between the theoretical model and empirical findings.…
