通过观察三个本科心理学班的128名受试者对“笑盒”产生的笑刺激的反应，评价了笑和/或微笑唤起的潜力。受试者在10次试验中记录他们是否笑和/或微笑，每次试验包括18秒的笑声样本，然后是42秒的沉默。大多数受试者对第一次笑的反应是大笑和微笑。然而，反应的极性迅速改变。到第10次试验时，很少有受试者笑了，大多数人觉得刺激“令人讨厌”。尽管其他研究也描述了隐藏的笑声效应，但它并没有考虑到这里证实的假设，即笑声本身会引起笑声，也许是通过激活特定的笑声特征检测器。这一结果与社会交流的神经学基础、人类行为学以及言语产生和感知理论有关。
The laugh- and/or smile-evoking potency of laughter was evaluated by observing responses of 128 subjects in three undergraduate psychology classes to laugh stimuli produced by a “laugh box.” Subjects recorded whether they laughed and/or smiled during each of 10 trials, each of which consisted of an 18-sec sample of laughter, followed by 42 sec of silence. Most subjects laughed and smiled in response to the first presentation of laughter. However, the polarity of the response changed quickly. By the 10th trial, few subjects laughed and/or smiled, and most found the stimulus “obnoxious.” Although other research has described canned-laughter effects, it did not consider the hypothesis confirmed here, that laughter itself evokes laughter, perhaps by activating a laughter-specific auditory-feature detector. This result is relevant to the neurological basis of social communication, human ethology, and theories of speech production and perception.
