Classroom Observations Of Attention-Deficit/Hyperactivity Disorder: Patterns And Characteristics Of Attention Over Time, Thomas M. Timko Jr.
Electronic Theses and Dissertations
Investigated differences in attentional processes between children diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) and their classroom peers. Models of attention gleaned from laboratory experiments provided a theoretical structure for hypothesizing between-group attentional differences. Seventy-five children with ADHD and 36 normal control children were observed in their regular classrooms over a 1-week time interval. Explication of between-group differences revealed that children with ADHD were approximately 21% less attentive on average. Both groups exhibited an accelerating-decelerating pattern of attention over time, however, children with ADHD cycled at a rate twice that of same-aged peers. Six variables derived from observed attention were examined for …

Physical And Behavioral Complaints In Children With Attention-Deficit/Hyperactivity Disorder (Adhd): Paradoxical Effects Of Methylphenidate, Maria M. Coiro
Electronic Theses and Dissertations
Hypotheses concerning paradoxical, psychostimulant-related side effects experienced by ADHD children were examined in the context of a double-blind, placebo-controlled, within subject (crossover) experimental design. Results revealed that behavioral and physical complaints were significantly higher under baseline relative to placebo and the four methylphenidate (MPH) conditions (5-mg, 10-mg, 15-mg, 20-mg) across three symptom categories: ADHD core/secondary symptoms, symptoms common to all children, and symptoms highly specific to MPH. No significant differences were found among active drug conditions. Implications of these findings for assessing and monitoring potential treatment emergent symptoms in children are discussed.
