研究了双手节律协调中的利手和注意力不对称性与运动速度的关系。在同相1：1频率锁定任务中，左利手和右利手被试控制右手或左手的振荡以接触空间目标。该任务是在三个频率的耦合运动。结合身体功能不对称性的协调动力学预测，左撇子和右撇子将在相反的方向上偏离零相对相位，对于偏好用手的目标，这种偏差会更大，并且在更高的运动频率下，这种偏差会更大。结果证实了主要的预测，并表明，由于利手的不对称性被放大的注意。
Handedness and attentional asymmetries in bimanual rhythmic coordination were examined as a function of movement speed. In an in-phase 1:1 frequency locking task, left-handed and right-handed subjects controlled the oscillations of either the right or the left hand so as to contact spatial targets. The task was performed at three frequencies of coupled movement. Coordination dynamics incorporating the body's functional asymmetry predicted that left-handers and right-handers would deviate from zero relative phase in opposite directions, that the deviation would be greater for preferred-hand targeting, and that this deviation would be greater at higher movement frequencies. The results confirmed the major predictions and suggested that asymmetry due to handedness is magnified by attention.
