Attention-deficit/hyperactivity disorder (ADHD) overdiagnosis and overtreatment unnecessarily exposes children to potential harm and contributes to provider and community skepticism toward those with moderate or severe symptoms and significant impairments, resulting in less supportive care. Yet, which sociodemographic groups of children are…

Children with academic and behavioral difficulties have been found to report overly positive self-perceptions of performance in their areas of specific deficit. Researchers typically investigate self-perceptions in reference to both actual performance and ratings by teachers, peers, and parents. However, few studies have investigated whether or…

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also…

A cue-target visual attention task was administered to 25 children (ages 10-12) with dyslexia. Results showed a general pattern of slower responses in the children with dyslexia compared to controls. Subjects also had longer reaction times in the short and long cue-target interval conditions (covert and overt shift of attention). (Contains…

A study of 30 Austrian children with dyslexia (grades 2-4) found that poor dual-task balancing was limited to children with higher attention-deficit/hyperactivity disorder (ADHD) ratings and that children with dyslexia without higher ADHD performed as well on dual-task balancing as age-matched control children.

This study compared parent and teacher behavioral ratings for 77 children (ages 5-16) diagnosed as having attention deficit disorder with hyperactivity (ADD/H), attention deficit disorder without hyperactivity (ADD/WO), or learning disabilities (LD). ADD/WO and LD children were rated similarly on symptoms of withdrawal and impulsivity but differed…

Comparison of eight-year-old children with attention deficit hyperactivity disorder (ADHD) (n=21), learning disorder (LD) (n=12), or both (n=27) on neuropsychological measures found that ADHD children were impaired in control and inhibition of impulses; children with LD in phonological awareness, verbal memory span, storytelling, and verbal IQ;…

A study compared developmental functioning, social, and environmental backgrounds of 62 overly active children (age 7), 37 with inattentive behavior, and 46 controls. Children with inattentive behavior were more likely to have general cognitive delays, particularly in language development and were more likely to have fathers with low occupational…

Eighty-eight children were identified as having attention deficit disorder with hyperactivity (ADD-H) and 58 with attention deficit disorder without hyperactivity (ADD). When the two subgroups were compared, teachers rated ADD-H children more problematic. Teacher ratings could discriminate ADD from ADD-H groups. Findings corroborated distinctions…

Comparison of behaviors exhibited by 19 hyperactive and 17 nonhyperactive (learning disordered) children found differences between groups to be more often qualitative than quantitative. Hyperactive students demonstrated more talking, unsystematic search, and motor impersistence while nonhyperactive students demonstrated more upper extremity…

This study, with 43 boys ages 8-12, found that children with relatively high concentrations of lead in their hair reacted significantly slower in a simple reaction-time task than did children with relatively low concentrations of lead in their hair. In addition, the former were significantly less flexible in changing their focus of attention.…

This report examines distinctions and interrelationships among attention deficit disorder and learning disability and oppositional/conduct disorder. A study with 98 children (mean age 10 years) referred for learning or behavior problems found a referral bias in that children referred to mental health settings differed from those referred to…

Examination of the motivational styles of 63 children with attention-deficit/hyperactivity disorder using parent, teacher, and self-ratings found ADHD children characterized by a preference for easy work, less enjoyment of learning, less persistence, and a greater reliance on external than on internal standards. Some differences between children…

A study involving 494 twins with a reading disability (RD) and 373 typical twins found that individuals with RD were more likely to meet criteria for attention-deficit/hyperactivity disorder (ADHD) and that the association between RD and ADHD was stronger for symptoms of inattention than for hyperactivity symptoms. (Contains extensive references.)…

The study with 51 boys (ages 7 to 9 years) found that subjects classified as having both attention deficit disorder/hyperactivity and learning disabilities demonstrated the most external locus of control with subjects classified as only learning-disabled intermediate and subjects classified as only having attention deficit disorder/hyperactivity…
