在物理学中，“夹带”是指两个具有相似基频的耦合振荡器的同步。在行为科学中，诱导指的是人类与有节奏的刺激同步运动的趋势。在这里，我们询问执行敲击任务的人类受试者是否会将他们的敲击带入以房间中环境背景噪音的伪装偷偷引入的未检测到的听觉节奏。受试者执行两个不同的任务，一个是他们以自己选择的稳定速度敲击手指，另一个是他们在自己选择的延迟之后进行一次突然的手指敲击。在这两种情况下，我们发现受试者倾向于与诱导调制同步，受试者之间的首选相位存在一些差异，与先前的研究一致。在重复敲击任务中，如果诱导刺激的频率远离受试者自己的自调频率，那么夹带就会被消除，这与物理学中夹带的性质一致。因此，未检测到的环境噪声可能会影响自发运动。这表明，无线索的行动决定从来都不是完全内源性的，而是受到感官环境的微妙影响。
In physics “entrainment” refers to the synchronization of two coupled oscillators with similar fundamental frequencies. In behavioral science, entrainment refers to the tendency of humans to synchronize their movements with rhythmic stimuli. Here, we asked whether human subjects performing a tapping task would entrain their tapping to an undetected auditory rhythm surreptitiously introduced in the guise of ambient background noise in the room. Subjects performed two different tasks, one in which they tapped their finger at a steady rate of their own choosing and one in which they performed a single abrupt finger tap on each trial after a delay of their own choosing. In both cases we found that subjects tended to tap in phase with the inducing modulation, with some variability in the preferred phase across subjects, consistent with prior research. In the repetitive tapping task, if the frequency of the inducing stimulus was far from the subject’s own self-paced frequency, then entrainment was abolished, consistent with the properties of entrainment in physics. Thus, undetected ambient noise can influence self-generated movements. This suggests that uncued decisions to act are never completely endogenous, but are subject to subtle unnoticed influences from the sensory environment.
