“…These results support the validity of the narrowly defined syndrome of pervasive hyperactivity rather than that of the more broadly defined ADDH diagnosis (see also Chee et al, 1989;Sandberg et al, 1978;Schachar et al, 1981;Taylor et al, 1986). At the same time, deficient inhibitory control cannot simply be attributed to the severity of disturbance: The mixed ADDH + CD group had the greatest number of symptoms of psychopathology yet did not have the most severe deficit in inhibitory control.…”

“…At the same time, deficient inhibitory control cannot simply be attributed to the severity of disturbance: The mixed ADDH + CD group had the greatest number of symptoms of psychopathology yet did not have the most severe deficit in inhibitory control. This is the second experiment in which we have observed that the ADDH + CD group does not demonstrate the same cognitive deficit as the ADDH group (Chee et al, 1989). Differences between these two subgroups have also appeared in studies of their clinical features.…”

“…Children who received both an interview-and a teacher-based diagnosis were considered pervasively hyperactive. However, from previous experience (Chee et al, 1989), we expected to find that only 50% of the ADDH group was pervasively hyperactive. The few cases of attention deficit disorder without hyperactivity were excluded from the study.…”

“…sively and situationally hyperactive ADDH subjects were also distinguished because evidence suggests that their cognitive function may be distinct (Chee, Logan, Schachar, Lindsay, & Wachsmuth, 1989;Sandberg, Rutter, and Taylor, 1978). The ADDH group was expected to show deficient inhibitory control compared with the normal control (NC) group (i.e, to have a lower or flatter inhibition function).…”

Two experiments investigated the development and pathology of inhibitory control in children. Inhibitory control was investigated with the stop-signal paradigm, which is based on a formal theory of inhibition and directly measures the mechanism of inhibition. The ability to inhibit developed little after Grade 2, but subjects with attention deficit disorder with hyperactivity (ADDH) showed deficient inhibitory control. Their deficient inhibitory control was attributable to the subgroup of ADDH subjects with pervasive hyperactivity who had a more severe inhibitory deficit than did the situational hyperactive subgroup, the normal group, and the pathological controls. These studies reflect the utility of the stop-signal paradigm as a measure of inhibitory control.

“…In contrast, as ISI becomes longer, behavioural activation declines (Sanders, 1998). In several studies it has been shown that performance of AD\HD children is impaired when a long ISI or preparatory interval is used (Zahn, Kruesi, & Rapoport, 1991), or long delays between cue and target (Swanson et al, 1991 ;Tomporowski, Tinsley, & Hager, 1994), long preresponse delays (Sonuga-Barke & Taylor, 1992), and slow event rates (Chee, Logan, Schachar, Lindsay, & Wachsmuth, 1989 ;Conte, Kinsbourne, Swanson, Zirk, & Samuels, 1986 ;Van der Meere, Shalev, Bo$ rger, & Gross-Tsur, 1995 ;Van der Meere, Stemerdink, & Gunning, 1995 ; Van der Meere, Vreeling, & .

This study was aimed at (a) replicating findings of slow and variable response execution and slow response inhibition in Attention Deficit\Hyperactivity Disorder (AD\HD), (b) investigating whether these deficits are specifically related to AD\HD or may also be observed in Oppositional Defiant Disorder (ODD), and children comorbid for AD\HDjODD, and (c) examining the role of activation level in task performance of children with AD\HD. To meet these aims, the stop paradigm was administered at three levels of activation, using a slow, medium, and fast presentation rate of stimuli, to 4 groups of children : 24 AD\HD children, 21 children with ODD, 27 children with comorbid AD\HDjODD, and 41 normal controls. As hypothesized, children with AD\HD exhibited a slow response execution process with considerable variability in the speed of responding compared to normal controls. Slow response execution was also observed in the comorbid AD\HDjODD group but not in the pure ODD group. Larger variability in the speed of responding was common to all disruptive groups compared with controls. In contrast to our hypothesis, no group differences emerged for inhibitory functioning. Finally, the slow event rate condition caused a further deterioration in the speed of the response execution process in both the AD\HD group and ODD group.

Sustained attention and response inhibition were examined in boys with full mutation fragile X syndrome (FXS) using adapted visual and auditory continuous performance tests (CPTs). Only 61% of 56 boys with visual CPT data and 54% of 52 boys with auditory data were able to demonstrate sufficient understanding to complete the visual and auditory CPTs, respectively. Mental age (MA) predicted whether boys with FXS were able to demonstrate understanding of the CPTs. The performance of boys with FXS who were able to complete the CPTs was compared to a sample of boys without disabilities matched on MA. Boys with FXS demonstrated similar or smaller declines in sustained attention over task time than their MA-matched peers on the visual and auditory CPTs, respectively, but consistently demonstrated greater declines in response inhibition over task time than their MA-matched peers. There were no differences between groups for response time of hits. Higher MAs consistently predicted better sustained attention and response inhibition over task time on the visual and auditory CPTs. Furthermore, boys taking psychotropic medication performed better at the beginning of most tasks, although their performance deteriorated at a faster rate over time, and boys rated as meeting diagnostic criteria for ADHD-hyperactive type had more difficulty over task time with response inhibition on the auditory CPT. For both boys with FXS and their MA matches, performance was better on the visual CPT than on the auditory CPT though this effect may be attributable to a number of factors other than the modality.

Effects of event rate and display time on sustained attention in hyperactive, normal, and control children

Abstract: Two experiments were conducted to determine whether hyperactive boys have a unique deficit in sustained attention. Groups with DSM-III diagnoses of attention deficit disorder (ADDH), conduct disorder (CD), ADDH + CD, and learning disorder were compared with normal controls on the
