Between-partner physiological linkage can be in-phase (changes in unison), or anti-phase (changes in opposite directions). In the context of conversation we predicted that in-phase linkage would occur when partners exert strong influence on each other; anti-phase linkage would occur due to the behavioral coordination of turn taking. To test this, blood pressure, inter-beat interval, and skin conductance were recorded from 44 heterosexual couples while they discussed how they influence each other's health-related behaviors. Partner influence was assessed in two ways: 1) partners' global perceptions of how they try to influence each other's health; and 2) behavioral manifestations of influence, specifically demand-withdraw behavior. As predicted, both measures of partner influence moderated physiological linkage of blood pressure such that at low levels of influence linkage was "anti-phase" and at high levels linkage was "in-phase." Several alternative hypotheses were ruled out; the effects were not due to relationship conflict, emotional experience, or simply the pattern of blood pressure over time. These results suggest that partner influence may be driving physiological linkage, which may be one avenue through which partners can affect each other's health.
伴侣间的生理联系可以同相（变化一致），也可以反相（变化相反）。在对话的背景下，我们预测当伴侣之间相互施加强烈影响时，同相联系会发生；反相联系则是由于行为的轮流转换而产生的协调。为了验证这一点，我们从 44 对异性恋夫妇那里记录了血压、心跳间隔和皮肤电导，同时他们讨论了他们如何影响彼此的与健康相关的行为。通过两种方式评估伴侣的影响：1）伴侣对他们试图影响彼此健康的总体看法；以及 2）影响的具体表现，即要求-撤回行为。正如预测的那样，伴侣影响的两个衡量标准都调节了血压的生理联系，使得在影响程度低的情况下联系是“反相”，而在影响程度高的情况下联系是“同相”。排除了几个替代假设；这些影响不是由于关系冲突、情感体验，或者仅仅是血压随时间的变化模式。这些结果表明，伴侣的影响可能是导致生理联系的原因，这可能是伴侣影响彼此健康的途径之一。
