The dominant error types were investigated as a function of phonological processing (PP) deficit severity in four groups of impaired readers. For this aim, an error analysis paradigm distinguishing between four error types was used. The findings revealed that the different types of impaired readers were characterized by differing predominant error…

Background: Impaired cognitive control has been frequently observed in children and young people with attention deficit hyperactivity disorder (ADHD) and might underlie the excessive hyperactivity and impulsivity in this population. We investigated behavioural and electrophysiological indices relevant to one domain of cognitive control; namely…

Background: Heightened error and conflict monitoring are considered central mechanisms in obsessive-compulsive disorder (OCD) and are associated with anterior cingulate cortex (ACC) function. Pediatric obsessive-compulsive patients provide an opportunity to investigate the development of this area and its associations with psychopathology.…

This study used a multiple baseline across participants design to examine the effects of self-monitoring and active responding on the reading comprehension of three high school seniors with learning disabilities and significant attention problems. The self-monitoring intervention required the participants to read a story and stop reading at three…

Background: The underlying mechanism of time perception deficit in long time intervals in attention-deficit/hyperactivity disorder (ADHD) is still unclear. This study used the time reproduction dual task to explore the role of the attentional resource in time perception deficits among children and adolescents with ADHD. Methods: Participants…

The Wisconsin Card Sorting Test (WCST) has frequently been used to assess executive functions in children with attention deficit hyperactivity disorder (ADHD). We first compared the performance of 15 children with ADHD to 15 children of a control group (age range 6 to 11) on the WCST and then examined the relationship among working memory,…

Objective/Method: The Conner's Continuous Performance Test (CPT) was administered to four groups of adult college students who self-referred for comprehensive psychoeducational evaluation and received either no diagnosis (n = 30) or a diagnosis of ADHD (n = 26), a psychiatric disorder (n = 17), or various cognitive deficits (n = 22). Results: The…

Several hypotheses related to Newman's (e.g., Patterson & Newman, 1993) response modulation hypothesis were examined among adolescents with attention-deficit/hyperactivity disorder (ADHD; n = 18) and normal controls (n = 23). Consistent with predictions, youth with ADHD committed more passive avoidance errors (PAEs) than controls during the latter…

This study aimed to extend earlier work (Wilding, Munir, & Cornish, 2001; Wilding, 2003) which showed that children (aged 6-15) who were rated by their teachers as having poor attentional ability made more errors on a visual search task than children rated as having good attentional ability. The present study used a simpler version of the search…

Eighty-two elementary school children with attention deficit disorder (ADD) and dyslexia made more errors than 83 normally reading children with ADD on a test of rhyme and alliteration. A subgroup of dyslexic children who were sensitive to rhyme and alliteration scored higher than other dyslexic children on a test of spatial ability. (Author/DB)

Article dispels the following myths about attention-deficit/hyperactivity disorder (ADHD): it has neurobiological base that can only be treated with medication; it must be treated with contingency management procedures; the children do not perform well under partial reinforcement schedules; and students must receive special-education services.…

A study involving 106 gifted children and 71 typical children (ages 6-9) evaluated the correlation between intelligence and performance on the Test of Variables of Attention (T.O.V.A). Results found gifted children with ADHD performed better on tasks of omission error, commission error, and response sensitivity than typical children with ADHD.…

Objective: Current understanding of executive function deficits in Attention-Deficit/Hyperactivity Disorder (ADHD) is derived almost exclusively from neuropsychological testing conducted in laboratory settings. This study compared children's performance on both neuropsychological and real-life measures of executive function and processing speed.…
