This study compared inhibitory functioning among ADHD subtype groups on manual and visual versions of the stop task. Seventy-six children, identified as ADHD/I (n = 17), ADHD/C (n = 43), and comparison (n = 20) completed both tasks. Results indicated that both ADHD groups were slower to inhibit responses than the comparison group on both tasks.…

In this study, we attempted to clarify whether distractibility in ADHD might arise from increased sensory-driven interference or from inefficient top-down control. We employed an attentional filtering paradigm in which discrimination difficulty and distractor salience (amount of image "graying") were parametrically manipulated. Increased…

Relationships between attention/executive functions and language learning were investigated in students in Grades 4 to 9 (N = 88) with and without specific learning disabilities (SLDs) in multiword syntax in oral and written language (OWL LD), word reading and spelling (dyslexia), and subword letter writing (dysgraphia). Prior…

This research tested and extended a laboratory-derived model of the origins of attitude certainty using a real attitude object: Teaching children with attention-deficit/hyperactivity disorder (ADHD). In Study 1, an experiment manipulated the amount of information, thought, and consistency of information delivered to pre-service teachers (n = 224)…

Few classroom behavioral interventions have been thoroughly studied using culturally and linguistically diverse populations, international student populations, or those from diverse socio-economic backgrounds. Yet, having such tools for school psychologists and teachers is critical for behavior management in the classroom. One important exception…

Truant youths frequently experience family problems, emotional/psychological issues, substance misuse, and delinquency. They are likely engaging in alcohol use and sexual risk behavior at a higher rate than the general youth population. Early intervention services would benefit them, their families, and society. We present interim findings from an…

Attention Deficit Hyperactivity Disorder (ADHD) is considered one of the most frequently diagnosed psychiatric childhood disorders. It affects 3-7% of school-aged children, interfering with their academic performance and social interactions. This study explored the knowledge and beliefs of teachers in Saudi Arabia about children with ADHD. The…

Background: Physical educators suggested that they are not well-informed about behaviors of children with disabilities, especially attention-deficit hyperactivity disorder (ADHD). Children with ADHD represent a significant number of students in school systems worldwide who often experience difficulties in performing fundamental movement skills.…

This study possessed 2 aims: (a) to develop and validate a clinician-friendly measure of academic problem behavior that is relevant to the assessment of adolescents with attention deficit/hyperactivity disorder (ADHD) and (b) to better understand the cross-situational expression of academic problem behaviors displayed by these youth. Within a…

Numerous studies have found significant comorbidity between Attention-Deficit/Hyperactivity Disorder (ADHD) and anxiety disorders in children (e.g., Bauermeister et al., 2007; Busch et al., 2002), but limited research has examined factors that may underlie or explain this relationship (e.g., Lilienfeld, 2003; Baldwin & Dadds, 2008). This study…

This study used a qualitative phenomenological approach within a constructivist paradigm to examine spelling and spelling motivation of four suburban Illinois high school students: two male seniors with LD, one male freshman with ADHD, and one female freshman with LD. The purposes of the study were to determine why students with writing goals and…

This dissertation was a qualitative examination of the band participation of three adolescents with Attention Deficit Hyperactivity Disorder (ADHD). This investigation of individual experiences and perceptions could help readers understand what adolescents with ADHD value about their band participation and what academic, interpersonal, and…

Attention-deficit/hyperactivity disorder (ADHD) affects between 2 and 8 % of college students. ADHD is associated with impaired academic, psychological, and social functioning, and with a wide array of negative outcomes including lower GPAs, graduation rates, and self-reported quality of life. The college environment often brings decreased…

Objective: The present study evaluated a 10-week psychosocial treatment designed specifically for children with attention-deficit/hyperactivity disorder (ADHD) and a comorbid anxiety disorder. Method: Using a nonconcurrent multiple baseline design, the authors treated 8 children ages 8-12 with ADHD, combined type, and at least 1 of 3 major anxiety…

Attention deficit/hyperactivity disorder is a common developmental disorder that can cause a motor-skill delay in children. Positive illusory bias (PIB)--the belief that one is better at performing a task or a skill than one actually is--may be one cause of this delay. Although nearly everyone experiences a mild and healthy PIB, students with ADHD…
