A series of attention tests were administered to two groups of hyperactive children and a control group of normal children. The first group of hyperactive children had both 'reported' hyperactivity (defined as having hyperactive behaviour reported at school and home) and 'clinic-observable' hyperactivity (defined as having hyperactive behaviour readily observable in a clinic interview). The second group had only 'reported' hyperactivity. The results of attention testing indicated that the children with both 'reported' and 'clinic-observable' hyperactivity had significant attentional difficulties in comparison with children with 'reported' hyperactivity as well as with the normal controls. On the other hand, the children with 'reported' hyperactivity had less evidence of attentional problems when compared to the normal children. Hence; the differentiation into 'reported' and 'clinic-observable' hyperactivity was of theoretical importance as clinic behaviour was a significant diagnostic marker in predicting performance in attention tests. The results of this study suggest the presence of different types of attention deficits in 'reported' and 'clinic-observable' hyperactivity respectively as well as heterogeneity in hyperactive children.
对两组多动儿童和一组正常儿童对照组进行了一系列注意力测试。第一组多动儿童既有“报告的”多动（定义为在学校和家中均报告有多动行为），也有“临床可观察到的”多动（定义为在临床访谈中易于观察到多动行为）。第二组仅有“报告的”多动。注意力测试结果表明，与仅有“报告的”多动的儿童以及正常对照组相比，既有“报告的”又有“临床可观察到的”多动的儿童存在显著的注意力困难。另一方面，与正常儿童相比，仅有“报告的”多动的儿童出现注意力问题的证据较少。因此，将多动区分为“报告的”和“临床可观察到的”具有理论重要性，因为临床行为是预测注意力测试表现的重要诊断指标。这项研究的结果表明，“报告的”和“临床可观察到的”多动分别存在不同类型的注意力缺陷，多动儿童存在异质性。
