当雄性金黄仓鼠在换笼后建立新的领地和家园时，其自由活动节律经常发生相移。在成对的动物相互作用半小时后，也经常发生类似的变化。当这些事件发生在仓鼠的主观白天的中间时，它们产生相位提前;当主观夜晚很晚时，它们产生相位延迟。在一天中的同一时间重复的社会互动可以以与相位响应曲线形状一致的方式产生活动节律。并不是所有的个体都被夹带，这是从相位响应曲线的适度幅度可以预测的。社会互动和其他干扰的影响可以通过由一般唤醒定相的振荡器来介导。目前的研究结果对解释药物引起的生物节律变化具有一定的意义。
Phase shifts in free-running activity rhythms of male golden hamsters, Mesocricetus auratus, often occur when they establish a new territory and home after a cage change. Similar shifts also often occur after pairs of animals interact with each other for half an hour. When these events take place during the middle of the hamsters'' subjective day, they produce phase advances: when late in the subjective night, they produce phase delays. Repeated social interactions at the same time of day can entrain activity rhythms in a way consistent with the shape of the phase response curves. Not all individuals become entrained, as is predictable from the modest amplitude of the phase response curve. The effects of social interactions and of other disturbances may be mediated through an oscillator phased by general arousal. The present findings have implications for the interpretation of drug-induced changes in biological rhythms.
