Long-term semantic memory (LTM) is known for affecting recall during working memory (WM) tasks. However, the way LTM intervenes in WM remains unknown. Moreover, the available findings are incongruent concerning how attention modulates the impact of LTM on WM. To examine this issue, the involvement of LTM representations in a complex span task was…

Previous research has shown attentional biases in children with autism spectrum disorders (ASD) when processing distressing information. This study examined these attentional patterns as a function of the type of stimulus (scenes and faces) and the stimulus valence (happy, sad, threatening, neutral) using a within-subject design. A dot-probe was…

The purpose of this study was to understand the relationship between executive functions and mathematical abilities to determine the contribution of these functions to math performance. In this study, 30 students were selected from among 4th graders of elementary school, in two groups with low achievement in mathematics (poor) and high achievement…

On the basis of longitudinal data across 9 years, this study examined the contribution of sustained attention and executive function to the poor cognitive and socioemotional adjustment of school-age children whose mothers had depressive symptoms during the child's infancy. Mothers (N = 1,364) reported depressive symptoms across their child's…

A dissociation between phonological and visual attention (VA) span disorders has been reported in dyslexic children. This study investigates whether this cognitively-based dissociation has a neurobiological counterpart through the investigation of two cases of developmental dyslexia. LL showed a phonological disorder but preserved VA span whereas…

The problem of how best to capture, direct, and enhance children's abilities to pay attention has been a central feature of educational thought and practices over a long duration. And, while having students pay attention in class has been a concern of teachers across the ages, beginning in the Enlightenment we find a significant shift in…

Analyzed the protocols of 52 clinic-referred children who were administered the Kaufman Assessment Battery for Children (K-ABC) as well as version of the Continuous Performance Test (CPT), a laboratory measure of attention. Results demonstrated significant interrelationships among K-ABC and CPT scores. (Author/ABL)

Applying optimal stimulation theory, the present study explored the development of sustained attention as a dynamic process. It examined the interaction of modality and temperament over time in children and adults. Second-grade children and college-aged adults performed auditory and visual vigilance tasks. Using the Carey temperament…

Objective: Compare observed and forecasted efficacy of mixed amphetamine salts extended release (MAS-XR; Adderall) with atomoxetine (Strattera) in ADHD children. Method: The authors analyze data from a randomized, double-blind, multicenter, parallel-group, forced-dose-escalation laboratory school study of children ages 6 to 12 with ADHD combined…

Eighteen hyperkinetic boys (ages 5-12) who had a history of successful drug treatment with methylphenidate were compared with a similar group of normal controls on a series of objective measures of activity and attentional problems. (Author/DLS)

Examined age-related changes in visual selective attention--ability to resist interference--in children 5 to 12 years old and adults. The interference effect on stimulus evaluation did not discriminate between age groups; however, the interference effect on correct response activation showed a pronounced age-related reduction, suggesting a…

Reviews "Attention Deficit Disorder: ADHD and ADD Syndromes" (D. R. Jordan), a short book about the characteristics and differences between attention deficit disorder (ADD) and attention deficit hyperactivity disorder (ADHD) and the effect they have on children and adults in their classrooms, home, and workplace. The book includes techniques for…

Recent theoretical analyses have implied that there may be age differences in children's tendency to exercise component selection, i.e., to attend selectively to a single component of stimulus objects in a learning situation. In the present study, 6 experiments were conducted, each designed to investigate developmental changes in component…

A research project sought to develop means of measuring children's attention to instructional films. Groups of five educable mentally handicapped (EMH) students watched films; observers noted their attention or inattention to the screen at five-second intervals. Data for the groups were then compiled via time series analysis procedures to yield a…
