The purpose of this experiment was to develop a methodology to investigate the postural expression of different emotions and attitudes using a technique which avoided the artificiality implicit in the use of a role play design. Subjects were asked to categorize tape-recorded extracts as either funny, sad, interesting or boring and to rate them in order of intensity. The posture displayed when listening to the recordings were then analysed according to these ratings, the whole interview being recorded on videotape without the subject's knowledge. Results showed distinctive postures for all four categories, such as dropping the head for sadness and leaning the head on one hand for boredom, thus providing empirical support for the utility of this methodology as a way of obtaining observations of non-verbal cues under controlled conditions without inducing any artificial self-consciousness in the subjects.
本实验的目的是开发一种方法，以研究不同情绪和态度的姿势表达，该方法采用了一种技术，避免了角色扮演设计中隐含的人为因素。要求受试者将录音片段分类为有趣、悲伤、有趣或无聊，并按强度顺序对其进行评分。然后根据这些评分分析听录音时所展示的姿势，整个访谈在受试者不知情的情况下被录制在录像带上。结果显示，所有四个类别都有独特的姿势，比如悲伤时低头，无聊时单手托头，从而为这种方法的实用性提供了实证支持，即它是一种在受控条件下获取非语言线索观察结果的方法，且不会在受试者中引发任何人为的自我意识。
