This paper selectively reviews research on event-related potentials (ERPs) during cognitive processing among children with attention deficit disorder. Research indicates that performance deficits during sustained attention are coupled with reduced amplitude of the P3B component of the ERP, which may be increased with stimulants. P3B latency and…

This paper critiques the methodologies used in studies finding that reading problems in children are not strongly associated with attention deficit disorder (ADD) and that medication used to treat ADD does not improve reading performance. New data are reported, suggesting increased reading difficulty with longer reading passages and improved…

Twenty subjects (ages 7-13) with attention deficit hyperactivity disorder were administered a battery of tests (including the Auditory Continuous Performance Test and the Token Test for Children) twice, first when not taking and then when taking methylphenidate. Results indicated significant improvement in performance on all measures when subjects…

Twenty-eight children (ages 5-13) with mental retardation, hyperactivity, and inattentiveness were administered fenfluramine and methylphenidate. Fenfluramine was superior to placebo on the memory task, whereas methylphenidate reduced commission errors on a continuous performance test. Methylphenidate caused shorter response times whereas…

A double-blind, placebo-controlled study examined effects of methylphenidate (Ritalin) on auditory processing in 32 children with both attention deficit hyperactivity disorder and central auditory processing (CAP) disorder. Analyses revealed that Ritalin did not have a significant effect on any of the central auditory processing measures, although…

This collection of papers focuses on definitions, assessment, assessment instruments, and distinctions between attention deficit disorder (ADD) and general learning disabilities or conduct disorders. Part I covers issues of definition and assessment in the following papers: "Methodological Issues in the Classification of ADD" (Jack Fletcher, et…

A survey of 1 school district found 136 students (out of 14,229) with attention deficit-hyperactivity disorder (ADHD) of which 77 were receiving special education services; 40 were also identified as behavior disordered, 22 as learning disabled, and 7 as mildly mentally retarded. Fifty students were in general education classrooms with resource…

Two discriminant function analyses were conducted to determine the cognitive/educational profile which differentiated 4 groups of 68 elementary/secondary level students: attention deficit disorder (ADD), with and without medication; learning disabilities (LD); and nonhandicapped. By treating the LD and nonmedicated ADD subjects as one group, a…

Twelve children (ages 7-8) with attention deficit hyperactive disorder were administered the Selective Auditory Attention Test twice: after the administration of methylphenidate and after the administration of a placebo. Results revealed no simple drug effect but a strong order effect. (Author/JDD)

Determining whether stimulant medication improves learning or long-term academic achievement in children with attention deficit-hyperactivity disorder involves consideration of (1) the prescription of higher than optimal doses, and (2) overinclusive treatment involving adverse responders. A study designed to overcome these theoretical deficiencies…

This study examined use of psychotropic drug treatment with 488 children and youth. It found that younger children, girls, and those with attention-deficit/ hyperactivity disorder were more likely than adolescent males with conduct disorders to receive medication. Stimulants, tricyclic antidepressants, and neuroleptics were the drug types most…

Comparison of 17 children with attention deficit hyperactivity disorder placed on methylphenidate drug therapy between first and second grade and matched controls found the methylphenidate group's achievement was lower both before and after medication, although after medication the group's rate of learning was similar to the control group's rate…

This study examines executive function and its relationship to attention dysfunction and working memory. It attempts to document the manifestations of executive function problems in school-related extended processing tasks, such as verbal problem-solving in math and reading of extended passages. Subjects (in grades 1-12) included 49 children with…

This review of 28 studies involving children with attention deficit-hyperactivity disorder concludes that there is little empirical support for cognitive training's clinical utility. The paper discusses cognitive training's efficacy as a single intervention and as an adjunct to stimulant treatment, and its impact on cognitive, academic, and…
