Past research has revealed that an individual's rhythmic limb movements become spontaneously entrained to an environmental rhythm if visual information about the rhythm is available and its frequency is near that of the individual's movements. Research has also demonstrated that if the eyes track an environmental stimulus, the spontaneous entrainment to the rhythm is strengthened. One hypothesis explaining this enhancement of spontaneous entrainment is that the limb movements and eye movements are linked through a neuromuscular coupling or synergy. Another is that eye-tracking facilitates the pick up of important coordinating information. Experiment 1 investigated the first hypothesis by evaluating whether any rhythmic movement of the eyes would facilitate spontaneous entrainment. Experiments 2 and 3 (respectively) explored whether eye-tracking strengthens spontaneous entrainment by allowing the pickup of trajectory direction change information or allowing an increase in the amount of information to be picked-up. Results suggest that the eye-tracking enhancement of spontaneous entrainment is a consequence of increasing the amount of information available to be picked-up.
过去的研究表明，如果关于节奏的视觉信息可用且其频率接近个体的运动频率，个体有节奏的肢体运动会自发地与环境节奏同步。研究还表明，如果眼睛跟踪环境刺激，对节奏的自发同步会得到加强。解释这种自发同步增强的一个假设是，肢体运动和眼睛运动通过神经肌肉耦合或协同作用联系在一起。另一个假设是，眼睛跟踪有助于获取重要的协调信息。实验1通过评估眼睛的任何有节奏运动是否会促进自发同步来研究第一个假设。实验2和实验3分别探讨了眼睛跟踪是否通过允许获取轨迹方向变化信息或允许增加可获取的信息量来加强自发同步。结果表明，眼睛跟踪对自发同步的增强是增加可获取信息量的结果。
