CLASSROOM OBSERVATIONS OF ATTENTION-DEFICIT/HYPERACTIVITY DISORDER: PATTERNS AND CHARACTERISTICS OF ATTENTION OVER TIME
Title
CLASSROOM OBSERVATIONS OF ATTENTION-DEFICIT/HYPERACTIVITY DISORDER: PATTERNS AND CHARACTERISTICS OF ATTENTION OVER TIME.
Creator
Timko Jr, Thomas, Rapport, Mark, University of Central Florida
Abstract / Description
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...
Show moreInvestigated 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 diagnostic utility using logistical regression, odds ratios, total predictive value, and receiver operating characteristics. Implications of these findings are discussed.

ADHD BEHAVIOR PROBLEMS AND NEAR- AND LONG-TERM SCHOLASTIC ACHIEVEMENT: DIFFERENTIAL MEDIATING EFFECTS OF VERBAL AND VISUOSPATIAL MEMORY

ADHD BEHAVIOR PROBLEMS AND NEAR- AND LONG-TERM SCHOLASTIC ACHIEVEMENT: DIFFERENTIAL MEDIATING EFFECTS OF VERBAL AND VISUOSPATIAL MEMORY.
Creator
Sarver, Dustin, Rapport, Mark, University of Central Florida
Abstract / Description
The current study examined verbal and visuospatial memory abilities as potential mediators of the relationship among ADHD behavior problems and near- and long-term scholastic achievement. Scholastic achievement was measured initially and at 4-year follow-up in an ethnically diverse sample of children (N = 325). Nested composite (reading, math, language) and domain-specific reading structural equation models revealed that ADHD behavior problems exerted a negative influence on scholastic...
Show moreThe current study examined verbal and visuospatial memory abilities as potential mediators of the relationship among ADHD behavior problems and near- and long-term scholastic achievement. Scholastic achievement was measured initially and at 4-year follow-up in an ethnically diverse sample of children (N = 325). Nested composite (reading, math, language) and domain-specific reading structural equation models revealed that ADHD behavior problems exerted a negative influence on scholastic achievement measures, both initially and at follow-up. Much of this influence, however, was mediated by verbal memory's contribution to near-term achievement, whereas visuospatial memory contributed more robustly to long-term achievement. For the domain-specific math achievement model, the collective influence of verbal and visuospatial memory fully mediated the direct influence of ADHD behavior problems on near-term math achievement, and visuospatial memory alone contributed to both near- and long-term achievement. In all models, measured intelligence made no contribution to later achievement beyond its initial influence on early achievement. The results contribute to the understanding of the developmental trajectory of scholastic achievement, and have potential implications for developing remedial programs targeting verbal and visual memory deficits in children with ADHD behavior problems.

Applied problem solving in children with ADHD: The mediating roles of working memory and mathematical calculation
Title
Applied problem solving in children with ADHD: The mediating roles of working memory and mathematical calculation.
Creator
Friedman, Lauren, Rapport, Mark, Beidel, Deborah, Vasquez, Eleazar, University of Central Florida
Abstract / Description
The difficulties children with ADHD experience solving applied math problems (i.e., word problems) are well documented; however, the independent and/or interactive contribution of cognitive processes underlying these difficulties is not fully understood and warrant scrutiny. The current study examines two primary cognitive processes integral to children's ability to solve applied math problems: working memory (WM) and math calculation ability (i.e., the ability to utilize specific facts,...
Show moreThe difficulties children with ADHD experience solving applied math problems (i.e., word problems) are well documented; however, the independent and/or interactive contribution of cognitive processes underlying these difficulties is not fully understood and warrant scrutiny. The current study examines two primary cognitive processes integral to children's ability to solve applied math problems: working memory (WM) and math calculation ability (i.e., the ability to utilize specific facts, skills, or processes related to basic math operations stored in long-term memory). Thirty-six boys with ADHD-combined presentation and 33 typically developing (TD) boys aged 8-12 years old were administered multiple counterbalanced tasks to assess upper (central executive [CE]) and lower level (phonological [PH STM] and visuospatial [VS STM] short-term memory) WM processes, and standardized measures of mathematical abilities. Bias-corrected, bootstrapped mediation analyses revealed that CE ability fully mediated between-group differences in applied problem solving whereas math calculation ability partially mediated the relation. Neither PH STM nor VS STM was a significant mediator. When modeled together via serial mediation analysis, CE in tandem with math calculation ability fully mediated the relation, explained 79% of the variance, and provided a more parsimonious explication of ADHD-related deficits in applied math ability. Results suggest that interventions designed to address applied math difficulties in children with ADHD will likely benefit from targeting basic knowledge of math facts and skills while simultaneously promoting the active interplay among these skills and CE processes.
