Findings of this study argue against the existence of a separate diagnostic category of hyperactivity. Hyperactivity and conduct-problem scales should be combined for purposes of rating child behavior problems. A category of "attention deficit disorder without hyperactivity" should be considered as a separate rating scale factor.…

The present study was designed to define the relationship between the supposed syndrome of hyperactivity and that of aggressive conduct disorder. (Author/DB)

Critiques the current concept of attention deficit hyperactivity disorder (ADHD) as it applies to primary school boys and girls. The article defines ADHD, presents a model of developmental contextualization, and shows ways in which theory can overcome limitations in current conceptualizations of ADHD and guide future pedagogy and research.

A study that investigated the relationships between exposure to lead and memory and attention in 313 boys (ages 9-12) in special-education schools in the Netherlands found blood-lead levels were higher in children with lower socioeconomic status and those with more hand-to-mouth behavior but did not influence cognitive factors.

A study investigated whether computer touch-screen technology could improve the attentional skills of three adolescents with severe mental retardation. Initially, prior reinforcement contingencies of individual stimuli failed to control their attention. Extended exposure to single stimulus training and conflict compounds, however, alleviated…

From fine-tuning muscular systems to integrating emotion and logic, the arts have important biological value. Motion and emotion are central to the arts and life itself. It is counterproductive to promote high performance standards while displacing skill development with computer technologies and reducing arts programs that move students from…

A study involving 13 right-handed, left hemisphere stroke patients with aphasia investigated the relationship between linguistic and nonlinguistic skills. No significant relationship was found between linguistic and nonlinguistic skills, and between nonlinguistic skills and age, education, or time post onset. Instead, individual profiles of…

A multimodal assessment of 19 children (ages 4-9) with learning disabilities was used to identify problem areas. The majority presented with deficits involving both visual and auditory modalities, as well as problems with motor abilities and concentration skills. Subgroups of problem areas were found to occur together. (Contains references.)…

Objective: Cognitive effects of stimulant medication were investigated in children with mental retardation (MR) and attention-deficit/hyperactivity disorder (ADHD). Method: Performance on tasks tapping sustained attention, visual and auditory selective attention, inhibition, and immediate memory was assessed for 24 children (mean age 10.9 years)…

This study evaluated the effects of choice making within functional communication training (FCT) to increase the task engagement of two participants with inappropriate behaviour. Pretreatment functional analyses indicated that both participants' inappropriate behaviour was maintained by escape. For one of the participants, inappropriate behaviour…

This study investigated whether specific behaviors observed in 30 month-old low-birthweight children are predictive of diagnosis of attention-deficit/hyperactivity disorder (ADHD) and school difficulties at age 8. Videotapes of 571 participants were coded using the Attention-Deficit Hyperactivity Disorder Observational Rating Scale (ADHD-ORS).…

Objective: Five studies have demonstrated the effectiveness of atomoxetine compared with placebo in reducing symptoms of attention-deficit/hyperactivity disorder (ADHD) based on parent reports. The primary objective of this clinical trial was to assess the efficacy of once-daily atomoxetine compared with placebo using teacher reports. Method: One…

This article re-evaluates the concept of "difficult temperament," documenting the difficulty of differentiating normal difficult behavior from difficult temperament, and difficult temperament from diagnosable psychiatric disorder. Researchers and clinicians acknowledge that childhood aggression is occurring with greater frequency and at younger…

Attention acts as the mind's "gatekeeper" by regulating and prioritizing the stimuli processed by the central nervous system. It is essential for cognitive performance, memory, and behavior, and we know that even slight deficiencies in attention compromise learning. Basic neuroscience research further indicates that attention consists of (fairly)…

The effects of maternal interactive styles on the production of referential communication were assessed in four groups of infants whose chronological ages ranged between 0;6 and 1;8. Two groups of infants with Down syndrome (DS), one (n = 11) with a mean mental age (MA) of 0;8.6, and the other (n = 11) of 1;4.5, were matched on MA with two groups…
