如果两个人划船，他们经常互相呼叫以同步划水。预计这一呼吁将促进定期的联合行动。因此，本研究使用与我们之前使用的相同任务（Masumoto和Inui in J Neurophysiol 109：1307-1314，2013 a）来检查言语对联合行动中互补和同步策略的影响。10对参与者产生周期性等长力，使得他们产生的力的总和是目标力，该目标力在右手最大自主收缩的5%和10%之间循环，间隔为1,000 ms。有三种语言条件与视觉信息的存在或不存在交叉。而两个参与者同步的话语/ba/与峰和谷的力量在“双方”的条件下，一个同步它与两个力量在“一边”的条件下，没有人说它在“无”的条件。当总力可见时，单侧和双侧条件的相关性低于无条件，尽管两个参与者产生的力之间的相关性在所有条件下都是负的。当总力不可见时，虽然在无条件下两个参与者产生的力和时间序列之间的相干性较低，但在单侧和双侧条件下，在1和3 Hz处的相干性较高。因此，尽管当目标可见时，周期性地说出一个音节会恶化互补力的产生，但当目标不可见时，它会促进他们的表现与彼此的时间同步。
If two people row a boat, they often call to each other to synchronize their strokes. It is anticipated that such a call promotes periodic joint action. The present study thus examined the effects of speech on both complementary and synchronous strategies in joint action using the same task as we used previously (Masumoto and Inui in J Neurophysiol 109:1307–1314, 2013a). Ten pairs of participants produced periodic isometric forces such that the sum of the forces they produced was the target force cycling between 5 and 10 % of maximum voluntary contraction with an interval of 1,000 ms with the right hand. There were three speech conditions crossed with the presence or absence of visual information. Whereas two participants synchronized an utterance/ba/with the peak and valley forces in the ‘Both’ condition, one synchronized it with both forces in the ‘One-side’ condition, and nobody uttered it in the ‘None’ condition. When the total force was visible, the One-side and Both conditions exhibited lower correlations than the None condition, although the correlation between forces produced by two participants was negative in all conditions. When the total force was invisible, although the coherence between force and time series produced by two participants was low under the None condition, it was high at 1 and 3 Hz under the One-side and Both conditions. Thus, although periodically uttering a syllable worsened complementary force production when the target was visible, it promoted synchronization of their performance to each other’s timing when the target was invisible.
