ABSTRACT According to the dynamic dominance model, the left cerebral hemisphere is specialized for the control of intersegmental dynamics and the right hemisphere for impedance control. Our aim was to test predictions from the dynamic dominance model in children by comparing performance between the right (preferred) and left hands in aiming. Three groups were compared: 4–7, 8–11, and 18–38 years old. Results showed higher movement linearity in the performance with the right hand in all age groups (P < .01), while initial directional error and endpoint accuracy were equivalent between hands. These results provided partial support for the dynamic dominance model.

侧向性动态优势模型的预测是否适用于儿童？

摘要 根据动态优势模型，大脑左半球专用于节间动力学控制，右半球专用于阻抗控制。我们的目标是通过比较右手（首选）和左手在瞄准时的表现来测试儿童动态优势模型的预测。比较了三组：4-7、8-11 和 18-38 岁。结果显示，所有年龄组右手的运动线性度都更高（P < .01），而双手之间的初始方向误差和终点准确度相当。这些结果为动态优势模型提供了部分支持。
