OBJECTIVE
The present article tests the hypothesis of a sustained attention deficit in children and adults suffering from ADHD.
METHOD
Vigilance and sustained attention of 52 children with ADHD and 38 adults with ADHD were assessed using a computerized vigilance task. Furthermore, the attentional performance of healthy children (N = 52) and healthy adults (N = 38) was examined.
RESULTS
Children and adults with ADHD performed significantly less well in the vigilance task than healthy participants (main effect for group). Furthermore, children and adults showed a significant decrease of performance over time (time-on-task effects). However, there was no greater decrement of performance with the passage of time in patient groups than in control groups (group-by-time interaction).
CONCLUSION
The present results do not support the hypothesis of a sustained attention deficit in children and adults with ADHD.
目的
本文检验患有注意力缺陷多动障碍（ADHD）的儿童和成人存在持续性注意力缺陷这一假设。
方法
使用计算机化警觉任务评估52名患有ADHD的儿童和38名患有ADHD的成人的警觉性和持续性注意力。此外，还对健康儿童（N = 52）和健康成人（N = 38）的注意力表现进行了检查。
结果
患有ADHD的儿童和成人在警觉任务中的表现明显不如健康参与者（组间主效应）。此外，儿童和成人的表现随时间显著下降（任务时间效应）。然而，与对照组相比，患者组的表现随时间推移并没有更大程度的下降（组×时间交互作用）。
结论
目前的结果不支持患有ADHD的儿童和成人存在持续性注意力缺陷这一假设。
