Analysis of emotions based on the finger pressure pattern: measured on Clynes' Sentograph

当受试者被暴露在描述“愤怒”、“快乐”、“悲伤”和“没有情绪”的图式面孔以及两种非面部刺激下时，我们检测了瞬时手指压力。在实验1中。九名女大学生被要求在不告知实验对象这个实验是为了测量情绪的情况下，通过按压克莱因Sentograph的指托来区分目标刺激和非目标刺激。在实验2。同样的研究对象被要求通过按压指托来表达他们对图式面孔的感受。结果表明，即使在辨别任务中，不同情绪的手指压力波形也存在差异。这种差异表明，即使在受试者没有意识到自己的情绪被测量的情况下，也可以用手指按压来测量情绪表达。波形的可识别特征是“悲伤”持续时间长，“愤怒”压力大。

We examined the transient finger-pressure when subjects were exposed to the schematic faces which depict "anger," "joy," "sadness." and "no emotion," and to two nonfacial stimuli. In Experiment 1. nine undergraduate women were asked to discriminate between those target stimuli and the nontarget stimuli by pressing on the finger rest of Clynes' Sentograph, without informing subjects that this experiment was to measure emotions. In Experiment 2. the same subjects were asked to express their feelings evoked by the schematic faces by pressing on the finger rest. Results indicate that even on the discrimination task, differentiation in the finger-pressure waveforms among emotions was observed. Such differentiation suggests the possibility of measuring the expression of emotions with finger pressure even when the subjects are not aware their emotions are being measured. The identifiable characteristics of the waveforms are the long duration for "sadness" and the strong intensity of pressure for "anger."
