This study examined the stability and variability of interpersonal coordination, in which one person breathed while the other moved a wrist back and forth with an inverted pendulum in hand. Nine pairs of subjects coordinated each other's movement in two relative phase modes. In one mode, Radial flexion-Inspiration and Ulnar flexion-Expiration (RIUE), one subject radially flexed the wrist as the other inhaled and ulnarly flexed it as the other exhaled. In the other, Ulnar flexion-Inspiration and Radial flexion-Expiration (UIRE) mode, the wrist was ulnarly flexed at inhalation, and radially flexed at exhalation. Results were as follows: (1) The two were more highly coordinated in RIUE mode than UIRE mode as the frequency of oscillation increased. (2) Phase transitions were observed from URIE to RIUE mode, as the frequency of oscillation increased. And (3) the more different in preferred frequency the pendulum and breathing movements were, the more deviated from the intended relative phase the coordination became. These results suggest that interpersonal coordination of breathing and wrist-pendulum movement is qualitatively equivalent to intra personal coordination between them.
本研究考察了人际协调的稳定性和变异性，其中一人呼吸，另一人手持倒立摆来回移动手腕。九对受试者以两种相对相位模式协调彼此的动作。在一种模式下，桡侧屈曲-吸气和尺侧屈曲-呼气（RIUE），一名受试者在另一名受试者吸气时桡侧屈曲手腕，在另一名受试者呼气时尺侧屈曲手腕。在另一种模式下，尺侧屈曲-吸气和桡侧屈曲-呼气（UIRE）模式，手腕在吸气时尺侧屈曲，在呼气时桡侧屈曲。结果如下：（1）随着振荡频率增加，两人在RIUE模式下的协调性比在UIRE模式下更高。（2）随着振荡频率增加，观察到从URIE到RIUE模式的相位转换。并且（3）摆锤和呼吸运动的偏好频率差异越大，协调性偏离预期相对相位的程度就越大。这些结果表明，呼吸与手腕-摆锤运动的人际协调在质量上等同于它们之间的人际内协调。
