在两个实验中的第一个实验中，专业演员回答有关他们个人经历、感受和信仰的问题时被录制下来。他们的叙述被转录下来，这些“剧本”被交给同性演员，他们试图以一种令人信服的方式描绘最初的受访者时，会被录制下来。自发的描述与相同叙述的排练版本没有区别，无论是演讲者做手势的时间比例，还是充满停顿和沉默停顿的比率。然而，自发叙述伴随着更多的词汇移动，并且包含了更大比例的语篇内沉默停顿。在第二个实验中，天真的受试者被展示了自发和排练的版本，并试图选择自发的版本。在不同的判断条件下，被试(1)看到无声的视频，(2)只听到音轨，或(3)都听到了声音，看到了图片。在所有三种判断条件下，对自发版本的识别都好于偶然性，但受试者通过声音和图像的组合比单独通过声音或图像更可靠地准确。(C)1994年学术出版社。
In the first of two experiments, professional actors were videotaped as they answered questions about their personal experiences, feelings, and beliefs. Their narratives were transcribed, and these ''scripts'' were given to actors of the same sex, who were videotaped as they tried to portray the original respondent in a convincing manner. Spontaneous portrayals did not differ from rehearsed versions of the same narratives in the proportion of time the speaker spent gesturing or in their rates of filled and silent pauses. However, spontaneous narratives were accompanied by more lexical movement and contained a greater proportion of intraclausal silent pauses. In a second experiment, naive subjects were shown both spontaneous and rehearsed versions and tried to select the spontaneous one. In different judgment conditions subjects (1) saw the video without sound, (2) only heard the sound track, or (3) both heard the sound and saw the picture. In all three judgment conditions, identification of the spontaneous version was better than chance, but subjects were reliably more accurate from the combined sound and picture than from either the sound or the picture alone.
