This work builds on the enfacement effect. This effect occurs when experiencing a rhythmic stimulation on one's cheek while seeing someone else's face being touched in a synchronous way. This typically leads to cognitive and social-cognitive effects similar to self-other merging. In two studies, we demonstrate that this multisensory stimulation can change the evaluation of the other's face. In the first study, participants judged the stranger's face and similar faces as being more trustworthy after synchrony, but not after asynchrony. Synchrony interacted with the order of the stroking; hence trustworthiness only changed when the synchronous stimulation occurred before the asynchronous one. In the second study, a synchronous stimulation caused participants to remember the stranger's face as more trustworthy, but again only when the synchronous stimulation came before the asynchronous one. The results of both studies show that order of stroking creates a context in which multisensory synchrony can affect the trustworthiness of faces.
这项研究基于面部呈现效应。当人们脸颊受到有节奏的刺激，同时看到别人的脸被同步触摸时，就会出现这种效应。这通常会导致类似于自我与他人融合的认知和社会认知效应。在两项研究中，我们证明这种多感官刺激可以改变对他人面部的评价。在第一项研究中，参与者在同步刺激后，会认为陌生人的脸和相似的脸更值得信赖，而异步刺激后则不然。同步与抚摸顺序相互作用；因此，只有当同步刺激先于异步刺激出现时，可信赖度才会改变。在第二项研究中，同步刺激使参与者将陌生人的脸记忆为更值得信赖，但同样只有当同步刺激先于异步刺激出现时才会如此。两项研究的结果都表明，抚摸顺序创造了一种情境，在这种情境中多感官同步可以影响面部的可信赖度。
