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…

Objective: Continuous performance tests are known to typically measure sustained attention but usually also yield parameters that potentially measure other subprocesses of attention. The aim of the present study was to test the factor structure of the Conners's Continuous Performance Test (CCPT) in a heterogeneous clinical sample consisting of…

This study evaluated the effects of color highlighting during a math computation task on performance accuracy and behavior of students with attention problems. Using a multiple baseline across participants design, three students solved math computation problems on worksheets with and without highlighting. Off-task behavior recorded from videotape…

Working memory is one of several putative core neurocognitive processes in attention-deficit/hyperactivity disorder (ADHD). The present work seeks to determine whether visual-spatial working memory is sensitive to motivational incentives, a laboratory analogue of behavioral treatment. Participants were 21 children (ages 7-10) with a diagnosis of…

Two studies evaluated the effects of within-task and competing visual stimulation on the mathematics performance and behavior of 17 children (ages 8-14) with attention deficit hyperactivity disorder. Results indicate the same high within-task simulation that enhanced student performance and reduced off-task behavior was effective only when…

Objective: To examine the relationship between time reproduction, performance variability, and sustained attention deficits in children with attention-deficit/hyperactivity disorder (ADHD) combined (ADHD-C) and inattentive (ADHD-I) subtypes, relative to matched controls. Method: Participants (age range 7.1-14.1 years) performed a time reproduction…

Despite clear evidence of decrements in performance over time coupled with a substantially greater perceptual sensitivity deficit in 10 hyperactive children compared to controls, the hyperactive group demonstrated no greater performance deficit with time on task. Results failed to support the hypothesis of a sustained attention deficit in…

In an investigation of the distractibility of hyperactive children and controls (N=24) in a focused attention task, differences in task efficiency were not significant. Differences in error percentages were associated with IQ. Variable reaction times in hyperactives are not to be explained in terms of a focused attention deficit. (JW)

The study compared performance on the Continuous Performance Task by 18 elementary grade children having attention deficit disorder with hyperactivity (ADDH), 15 conduct disordered, 26 mixed conduct disorder and ADDH, 15 emotionally disturbed, 22 learning disabled, and 15 nondisabled students. Hyperactive children did not demonstrate a unique…

A counterbalanced, multiple-baseline, across-subjects design was used to determine if attention and performance monitoring had differential effects on the on-task and spelling study behavior of 6 elementary students with attention-deficit/hyperactivity disorder (ADHD) in the general education classroom. Both self-monitoring of attention and…

This study examines the effects of using response cost in combination with positive reinforcement procedures in helping two second grade students with attention deficit hyperactivity disorder maintain their attention in the classroom. This involved the loss of reinforcers/points contingent upon inappropriate behavior in the classroom, in addition…

The study investigated the effects of Information and Communication Technologies (ICT) use on pupils with Attention Deficit Hyperactivity Disorder (ADHD) symptoms. Nine Greek primary school pupils with ADHD symptoms and four others with no such deficit worked on a computer, either individually or collaboratively, once a week for a six-week period.…

Examined the efficacy of an automated reinforcement device, the Attention Training System (ATS), in decreasing off-task behavior in an 11-year-old, fifth-grade student who had been diagnosed as being affected with ADHD and had been placed in Special Education Resources Room programming. Results indicated success in three subject areas. (JBJ)

Experimenter presence (representing external control) or absence during task presentation were the two conditions under which attentional performance of 16 hyperactive and 16 control subjects (ages 7-12) was assessed. Results suggested noncompliance (an application deficit rather than an ability deficit) as a major contributor to poor performance…

The optimal stimulaton theory (which proposes that hyperactive children are more readily underaroused than nonhyperactive children and should thus derive greater gains from stimulation added to repetitive copying tasks than comparisons) was tested with 16 adolescents, rating high on attention and behavior problems, and 16 controls. Matched pairs…
