The purpose of this study was to demonstrate the effects of a motor coordination relationship on the executive function of older adults. Bi-manual coordination and eye-hand coordination responses were used to evaluate motor coordination. To assess executive function, the Stroop Color-Word Test was used, which is considered as an ideal tool for studying typical and atypical executive processing. Methodology in this study established which differences in variables were and were not predictive of different Stroop interference scores to determine the most robust motor coordination features related to executive function. Also, these significances were applied to a system approach which considers specific ideas about synergy. The analysis revealed that some significant relationships were detected in light of the variance of Stroop error effects. In particular, discrete bi-manual spatial coordination was most strongly related to the Stroop error effects. This result reflects that the asymmetrical spatial coordination pattern can be regarded as a significant contributor to the executive function of the elderly. Furthermore, these relationships represent the synergetic predictive ability of the model for promising factors to offer new insight via this system, through which the order may take on a new pattern. These findings can be identified as a fresh investigation of the Stroop interference task, providing a template with which motor coordination abilities and the behavioralneuro-aging of the cognitive function can be assessed.
