Using a quantitative measure of unintended mirror-movements in the contralateral limb during a unimanual task, the magnitude of associated movement across the ages from six to 16 years was determined. Male children in five age-groups (means 6.5, 8.5, 10.4, 12.4 and 16.5 years) were asked to squeeze their index finger and thumb together to various percentages of their own maximal volitional force. Results indicate that the 6.5-year-old group differ from all other age-groups, exhibiting significantly greater associated movements at all levels of force. The results are discussed in terms of the development of inhibitory control over innate neuromotor synergies.
通过在单手任务中对侧肢体意外镜像运动的定量测量，确定了6至16岁各年龄段相关运动的幅度。对五个年龄组（平均年龄分别为6.5岁、8.5岁、10.4岁、12.4岁和16.5岁）的男童进行测试，要求他们将食指和拇指捏合到自身最大自主力量的不同百分比。结果表明，6.5岁组与所有其他年龄组不同，在所有力量水平下均表现出明显更大的相关运动。根据对先天神经运动协同作用抑制控制的发展对结果进行了讨论。
