对有和无运动协调障碍儿童的认知和运动协调技能进行了为期一年的随访调查。最初，儿童年龄在4至6岁之间。在连续两年中，对执行功能（更新、转换、抑制、干扰控制）、运动协调（儿童运动评估组合-2）和健康（Korperkoordinations-Test fur金德）进行了适当的测试。几个背景变量（年龄，社会经济地位，医疗支持，临床干预，休闲活动）和潜在的主持人（非语言智力，反应时间，视觉感知）进行了控制。配对样本包括48名对照儿童和48名运动协调障碍儿童。在一年的时间里，孩子们的执行功能得到了极大的改善。在运动协调能力方面，一半的受损儿童赶上了对照组儿童的水平（缓解组），而剩下的一半则没有改善（持续组）。与持续组相比，缓解组的儿童在两个测量点都表现出明显更好的干扰控制。执行功能和运动协调之间的相关性在持续组中是显著的，但在缓解组中不显著。的研究结果进行了讨论，在执行功能，特别是抑制过程中的作用，自动化的运动协调任务。
Cognitive and motor coordination skills of children with and without motor coordination impairments were examined with a one-year follow-up investigation. Initially, children were between 4 and 6years old. Age-appropriate tests of executive functions (updating, switching, inhibition, interference control), motor coordination (the Movement Assessment Battery for Children-2) and fitness (the Korperkoordinations-Test fur Kinder) were administered in two consecutive years. Several background variables (age, socioeconomic status, medical support, clinical interventions, leisure activities) and potential moderators (nonverbal intelligence, reaction time, visual perception) were controlled. The matched sample consisted of 48 control children and 48 children with motor coordination impairments. The children's executive functions dramatically improved during the one-year period. With regard to motor coordination performance, half of the impaired children caught up to the control children's level (remission group), while the remaining half showed no improvement (persisting group). Compared to the persisting group, the children in the remission group showed markedly better interference control at both measurement points. The correlation between executive functions and motor coordination is significant in the persisting group, but not in the remission group. The results of the study are discussed in the light of the role of executive functions, especially inhibition processes, for the automatization of motor coordination tasks.
