Hyperactive children have been described as motorically clumsy. To explore the validity of this assertion, an experiment using the additive factor method was designed to examine motor organization and execution in hyperactive children. Four groups of boys aged 7 to 8 years took part in the study: (1) a pure hyperactive (HA) group, N=20; (2) a pure conduct-disordered (CD) group, N=18; (3) a mixed hyperactive/conduct-disordered (HA+CD) group, N=12; (4) a normal (N) control group, N=22. While the small sample size precluded a definitive conclusion, the results indicated that neither HA nor CD children showed any motor organization or execution deficit in a simple sequential key-tapping task. Given previous findings indicating that hyperactive children show deficits in more complex motor coordination skills, the generalizability of our negative results needs to be examined on other more complex tasks.
多动儿童被描述为运动笨拙。为了探究这一论断的有效性，设计了一项使用加法因素法的实验，以检验多动儿童的运动组织和执行情况。四组7至8岁的男孩参与了该研究：（1）单纯多动（HA）组，N = 20；（2）单纯品行障碍（CD）组，N = 18；（3）多动/品行障碍混合（HA + CD）组，N = 12；（4）正常（N）对照组，N = 22。虽然小样本量妨碍得出明确结论，但结果表明，在简单的顺序按键任务中，HA组和CD组儿童均未表现出任何运动组织或执行缺陷。鉴于先前的研究结果表明多动儿童在更复杂的运动协调技能方面存在缺陷，我们的阴性结果的普遍性需要在其他更复杂的任务上进行检验。
