Attention-deficit hyperactivity disorder (ADHD) is a heterogeneous disorder currently defined by clinical history and behavioral report of impairment. The Attention Network test (ANT) gives measures of different aspects of the complex process of attention.
We ask if children with Attention Deficit Hyperactivity Disorder (ADHD) will show a characteristic pattern of deficits on this test.
The sample included 40 children (M=9 years) who performed the "Attention network test". Children with an ADHD diagnosis (N=20) were compared to a control group (N=20).
The group of children with ADHD showed slower reaction times in all conditions (mean RT=866 ms; SD=234,063). Children with ADHD showed a significant impairment in their executive control system compared to healthy subjects, with slower reaction times in incongruent conditions and lower accuracy scores (RT=1064 ms; F(1.38) p=0.02). Our results showed that spatial orienting and alerting in ADHD was no different than controls (p=0,68). ADHD group showed a greater variable response (p=0,0001).
The present study showed that impairment in executive control system and variability measures are the characteristic pattern of deficits in children with ADHD.
注意力缺陷多动障碍（ADHD）是一种异质性疾病，目前通过临床病史和功能损害的行为报告来定义。注意力网络测试（ANT）可测量注意力复杂过程的不同方面。
我们探究患有注意力缺陷多动障碍（ADHD）的儿童在该测试中是否会表现出特征性的缺陷模式。
样本包括40名儿童（平均年龄9岁），他们进行了“注意力网络测试”。将被诊断为ADHD的儿童（n = 20）与对照组（n = 20）进行比较。
患有ADHD的儿童组在所有条件下反应时间均较慢（平均反应时间 = 866毫秒；标准差 = 234,063）。与健康受试者相比，患有ADHD的儿童在执行控制系统方面存在显著损害，在不一致条件下反应时间较慢且准确率得分较低（反应时间 = 1064毫秒；F(1.38) p = 0.02）。我们的结果表明，ADHD儿童的空间定向和警觉性与对照组无差异（p = 0.68）。ADHD组表现出更大的反应变异性（p = 0.0001）。
本研究表明，执行控制系统损害和变异性测量是ADHD儿童缺陷的特征模式。
