Studying within-person variability in children's behavior is frequently hindered by challenges collecting repeated observations. This study used wearable accelerometers to collect an intensive time series (2.7 million observations) of young children's movement at school (N = 62, M[subscript age] = 4.5 years, 54% male, 74% Non-Hispanic White) in…

We used latent profile analysis to identify major behavioral self-regulation profiles among children who were assessed as developmentally vulnerable in terms of hyperactivity and inattention. We examined three domains of behavioral regulation: (a) cognitive--behavioral regulation by way of learning behaviors; (b) social-behavioral regulation by…

Background: Children with attention deficit hyperactivity disorder (ADHD) and with autism spectrum disorders (ASD) are known to have cognitive control deficits. Some studies suggest that such deficits may be reduced when motivation is increased through tangible reinforcers. Whether these deficits can also be modulated by non-tangible reinforcers…

Prospectively followed 100 hyperactive children and 60 controls over 8 years into adolescence. At followup, hyperactive children demonstrated impaired academic achievement; impaired attention and impulse control; and greater off-task, restless, and vocal behavior during an academic task compared with controls. Concluded that hyperactive children…

The study adopted a person-centered approach to examine whether clusters of children could be identified on the basis of temperament profiles assessed on four occasions from infancy to early childhood, and if so whether differing temperament clusters were associated with subsequent differences in behavior problems, social skills, and school…

Hyperactive and normal elementary students (N=27) were administered story conditions that differed in presentation rate and information relevance and repetition to determine whether listening problems of hyperactive children could be attributed to delays that encourage impulsive responding. Findings suggested that rate of information presentation…

In his lectures published in 1902, George Still described 43 children in his clinical practice who had serious problems with sustained attention and self-regulation. George Still certainly did not use the current terminology for this disorder, but many historians of attention deficit hyperactivity disorder (ADHD) have inferred that the children he…

Objective: With the increase in diagnosis and treatment of attention deficit hyperactivity disorder (ADHD) in adults, it is expected that more resident physicians will require accommodations so that their academic performance and clinical competency can be measured adequately. The authors provide an overview of the requirements and issues…

A study was conducted involving eight hyperkinetic males (11-15 years old) to determine if Ss receiving electromyography (EMG) biofeedback training would show a reduction in frontalis muscle tension, hyperactivity, and lability, and increases in self-esteem and visual and auditory attention span. Individual 45- and 30-minute relaxation exercises…

Thirty-two hyperactive children (ages 5-11) and 32 controls were tested on (1) a component selection task, measuring serial memory and incidental learning and (2) a cancellation task, assessing attentional variables and distractibility. It was concluded that a deficit in sustained attention and impulsivity best described the group differences.…

Two experiments were implemented in which hyperactive children were exposed to models of their own age level. It was hypothesized that modeling treatments designed to demonstrate reflective problem-solving strategies would improve the problem-solving ability of both normal and hyperactive children, and that, concomicantly, children's ability to…

A treatment regimen demands extensive diagnostic work-ups. In most situations where a specific diagnostic finding does not occur, the appropriate treatment will be multitreatment. Drug treatment will continue to predominate, with research emphasis directed toward attempts to predict which children will respond positively to methylphenidate.…

Hyperactivity and impulsivity, as well as poor attention in its various forms, are encountered much more often in atypical populations, including those with learning disabilities. Many children with disabilities display attentional difficulties or some kind of lethargic, dreamy state. These problems are amenable to treatment by physical educators…
