Response latencies of 27 learning disabled (LD) and 27 normal control boys (8-11 years old) were compared on a picture-word interference task. Both LD and control Ss exhibited greater interference effects (longer response latencies) when naming pictures (versus naming words) and when categorizing words (versus categorizing pictures).

Comparison of 24 elementary school-age children with attention deficit hyperactivity disorder (ADHD) and 20 children with attention deficit disorder without hyperactivity (ADD/noH) on a comprehensive neuropsychological assessment found math achievement test scores for students with ADD/noH were significantly lower than those for students with…

This study investigated taxonomic clustering and use of frequency associations as features in the semantic memory of children (n=30 in grades two and six) with learning disabilities (LD). Results suggested that, when individual child-generated word lists (i.e., meaningful) are used, children with LD may not be impaired in their ability to utilize…

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…

Two classification procedures for identifying children with reading disabilities were compared, differing in their use of intelligence quotient (IQ). Results indicated that abandoning IQ in classification had a very limited impact on the number of children identified as reading disordered, but that use of IQ resulted in more high-IQ children being…

A sample of 74 Finnish children with mild learning disabilities and 57 controls were grouped into 5 subgroups (normal, general language, visuo-motor, general deficiency, naming) and followed from the third to the sixth grade. Results indicated that neuropsychological profiles were generally maintained, with changes related to progress in reading.…

A study of 62 children (ages 7 to 12) with attention-deficit hyperactivity disorder (ADHD) and 62 controls found that behavioral variables established robust, statistically significant differences between groups. Children with ADHD also scored worse on 31 out of 61 neuropsychological variables, but obtained better scores on WISC-R Comprehension…

Four studies examined reading disabilities in elementary school children from the perspective of componential skills of reading. A principal-components analysis of the performance of 139 children on reading-related tasks yielded two factors: decoding and comprehension. Factor analyses indicated that orthographic skills and processing speed could…

A study examined the stability over 19 months of academic subtyping classification of 80 children (ages 9 to 13) representing four subtypes of arithmetic disabilities (AD). Approximately half of the sample retained AD regardless of identification method. Children with deficits in arithmetic, reading, and spelling disabilities exhibited the…

A study involving 1,123 children investigated the relationship between naming speed and phonological awareness skills and the implications for the classification of children at risk of reading disability. Results found a positive correlation between naming speed and phonological awareness and indicate this relationship will affect any comparison…

This study investigated specific processing strengths and weaknesses among 75 readers, ages 6-10, with no oral language deficits. Unsuccessful readers of different ages showed similar information processing patterns, and differed from successful first-grade readers on short-term auditory/working memory and decoding/encoding. Three potential…

A study that followed 1,008 children from prekindergarten through grade seven or eight for 13 years found that defining reading comprehension disability in terms of a discrepancy between group-administered tests of listening and reading comprehension provided a fairly accurate estimate of the stability, gender ratio, and prevalence of the…
