Peer reviewed Peer reviewed
Direct linkDirect link
Strand, Michael T.; Hawk, Larry W., Jr.; Bubnik, Michelle; Shiels, Keri; Pelham, William E., Jr.; Waxmonsky, James G. – Journal of Abnormal Child Psychology, 2012
Working memory (WM) is considered a core deficit in Attention-Deficit/Hyperactivity Disorder (ADHD), with numerous studies demonstrating impaired WM among children with ADHD. We tested the degree to which WM in children with ADHD was improved by performance-based incentives, an analog of behavioral intervention. In two studies, WM performance was…

Stimulant Treatment Reduces Lapses in Attention among Children with ADHD: The Effects of Methylphenidate on Intra-Individual Response Time Distributions
Peer reviewed Peer reviewed
Direct linkDirect link
Spencer, Sarah V.; Hawk, Larry W., Jr.; Richards, Jerry B.; Shiels, Keri; Pelham, William E., Jr.; Waxmonsky, James G. – Journal of Abnormal Child Psychology, 2009
Recent research has suggested that intra-individual variability in reaction time (RT) distributions of children with ADHD is characterized by a particularly large rightward skew that may reflect lapses in attention. The purpose of the study was to provide the first randomized, placebo-controlled test of the effects of the stimulant methylphenidate…

Fundamental Movement Skills and Children with Attention-Deficit Hyperactivity Disorder: Peer Comparisons and Stimulant Effects
Peer reviewed Peer reviewed
Direct linkDirect link
Harvey, William J.; Reid, Greg; Grizenko, Natalie; Mbekou, Valentin; Ter-Stepanian, Marina; Joober, Ridha – Journal of Abnormal Child Psychology, 2007
The purpose of this study was to compare the fundamental movement skills of 22 children with attention-deficit hyperactivity disorder (ADHD), from 6 to 12 years of age, to gender- and age-matched peers without ADHD and assess the effects of stimulant medication on the movement skill performance of the children with ADHD. Repeated measures analyses…

Self-Handicapping Prior to Academic-Oriented Tasks in Children with Attention Deficit/Hyperactivity Disorder (ADHD): Medication Effects and Comparisons with Controls
Peer reviewed Peer reviewed
Direct linkDirect link
Waschbusch, Daniel A.; Craig, Rebecca; Pelham, William E., Jr.; King, Sara – Journal of Abnormal Child Psychology, 2007
The authors examined self-handicapping prior to academic-oriented tasks in children with and without ADHD and examined whether stimulant medication influenced self-handicapping. Participants were 61 children ages 6 to 13, including 22 children with ADHD tested after taking a placebo, 21 children with ADHD tested after taking stimulant medication,…

Methylphenidate Increases Selectivity of Visual Scanning in Children Referred for Hyperactivity.
Peer reviewed Peer reviewed
Flintoff, Margaret M.; And Others – Journal of Abnormal Child Psychology, 1982
Visual scanning patterns were investigated in 32 children (mean age 9.8 years) referred for hyperactivity in a double blind crossover comparison of methylphenidate and placebo treatments. Results suggested that the stimulant drug may increase attentional selectivity even when such a shift fails to produce improvement in task performance. (Author)

The Effects of Methylphenidate on Levels of Processing and Laterality in Children with Attention Deficit Disorder.
Peer reviewed Peer reviewed
Malone, Molly A.; And Others – Journal of Abnormal Child Psychology, 1988
Effects of stimulant medication on word processing were assessed in 31 attention-deficit-disordered children (ages 6-16). Results suggested that methylphenidate may selectively improve the phonological level of word processing, and that favorable effects are produced through inhibition of excessive right hemisphere activity in response to task…

Performance and Private Speech of Children with Attention-Deficit/hyperactivity Disorder while Taking the Tower of Hanoi Test: Effects of Depth of Search, Diagnostic Subtype, and Methylphenidate
Peer reviewed Peer reviewed
Kopecky, Helena; Chang, H. Theresa; Klorman, Rafael; Thatcher, Joan E.; Borgstedt, Agneta D. – Journal of Abnormal Child Psychology, 2005
We administered the Tower of Hanoi to demographically comparable samples of control participants (n = 34) and children with the Combined (n = 22) and Inattentive subtypes (n = 19) of Attention-Deficit/Hyperactivity Disorder (ADHD). Controls excelled over children with the Inattentive subtype, who outperformed patients with the Combined subtype.…
