Background: Traditional treatment for the behavioural symptoms in autism spectrum disorder (ASD) remains unsatisfactory. There is an urgent need for new, biologically relevant therapies that target both the core and comorbid symptoms that children may experience. This article builds on research previously published by the authors. Method: We…

Objective: To bridge theory of response inhibition and learning in children with ADHD. Method: Thirty ADHD and 30 non-ADHD children (ages 9-12) were compared under concurrent variable interval (VI-15 sec., VI-30 sec. and VI- 45 sec.) reinforcement schedules that required the child to switch between the three schedules under conditions of…

Objective: To investigate single and combined effects of stimulant medication and contingencies on the performance of ADHD children with tasks involving different cognitive demands. Method: Children diagnosed with ADHD participated in a within-subjects design. At two separate sessions, children on either medication or placebo (administered in a…

In this challenge study of 18 children, aged 4-12, on the Feingold Diet to reduce hyperactivity, evaluations of 14 objective measures in a double-blind, cross-over design yielded no significant differences between diet infraction and noninfraction. (Author/SJL)

This study reports on an intervention involving massage, yoga and relaxation delivered to young children with emotional and behavioural difficulties. Children (n = 126) were invited to participate in the Self-discovery Programme (SDP) with parental consent. A total of 107 children aged 8-11 years completed the SDP and all measures. Children were…

Phase II of a study on the effectiveness of B. Feingold's recommended diet for hyperactive children involved the nine children (mean age 9 years) who had shown the "best" response to diet manipulation in Phase I. Each child served as his own control and was challenged with specified amounts of placebo and artificial color containing food…

Mother/child interactions of 60 hyperactive children 5, 6, 7, 8 and 9 years of age were studied during free play and task periods. Significant age effects and several drug effects were found in the task period. Drug effects were essentially the same across all five age levels. (Author/RH)

Objective: Children with ADHD experience peer problems that may place them at risk for adverse outcomes. Using a short-term longitudinal design, this study links specific behaviors to peer functioning in groups of previously unfamiliar children with ADHD. Method: The participants were 268 children with ADHD who took part in an intensive summer…

A 6 1/2-year-old hyperactive boy was taught to reduce his muscular activity and tension through the use of electromyographic biofeedback for 11 sessions. (Author/DB)

Early theories of hyperactivity and learning disabilities are discussed in this paper. Several approaches to treatment and intervention (behavioral, indirect, cognitive behavior, and stimulant medication) are described. (Author/A M)

This study investigated hot and cool aspects of cognitive control in children with Attention Deficit Hyperactivity Disorder (ADHD). The study aimed to: (1) replicate the postulated response inhibition deficit of children with ADHD; (2) explore whether children with ADHD choose disadvantageously in a decision-making task and to explore the…

A state-of-the-art review of childhood hyperactivity, conclusions from empirical findings, and implications for clinical work are presented. Diagnosis and etiology of hyperactivity are explored with emphasis on the multivariate aspects of the disorder and the difficulty of specifying behavior which is by definition unpredictable. (PHR)

The effects of choosing academic assignments on the undesirable behaviors manifested by a second-grade student with attention deficit hyperactivity disorder were analyzed. The student was in a general education classroom. A reversal design showed that undesirable behaviors decreased when the student was given a choice of academic assignments.…

Objective: Methylphenidate has four optical isomers due to two asymmetries (erythro-threo and dextro-levo). The initial commercial formulation eliminated the erythro isomer, but the dextro-levo asymmetry was racemic, with equal amounts of d and l-threo isomers (d,l-MPH). Previous work has suggested that the d-threo isomer methylphenidate (d-MPH)…
