This discussion of issues of definition and classification of attention deficit disorder (ADD) emphasizes the heterogeneity of the diagnosis, the overlap of ADD with reading disability, and lack of consistency across studies. A systematic classification study is proposed to develop a unitary, empirically derived classification for ADD. (Author/DB)

This response to a paper by Linda Siegel (EC221505) on the relationship between Intelligence Quotient and learning disabilities addresses the differences between classification and identification, limitations in Siegel's conceptualization of intelligence, and the representation of the language and learning domains subsumed within the learning…

The phonemic awareness of 100 children in the second semester of kindergarten was evaluated through analysis of their invented spelling patterns. A taxonomy of 10 invented spelling patterns and 21 response types was developed. A developmental ordering of spelling patterns is proposed and relationships among phonological awareness, spelling, and…

The performance of reading-disabled, math-disabled, slow-learning, under-achieving, and normal-achieving children (total n=143) was compared on verbal and visual-spatial working memory measures under initial, gain, and maintenance testing conditions. Ability group classifications changed under dynamic testing conditions. The study demonstrated the…

Four studies involving 45 subjects found that children (ages 9-14) with nonverbal learning disabilities syndrome exhibited specific patterns of impairment in mechanical arithmetic and in psychosocial functioning, whereas children with poor performance in reading and spelling exhibited patterns of academic deficits (including arithmetic), but not…
