MAPD: A Multi-subject Affective Physiological Database

A multi-subject affective physiological database containing 380 physiological records of 250 subjects is presented in this paper. While the subjects individually watch the amusement, anger, fear, or sadness elicitation film clip, their oxygen saturation (OXY), galvanic skin response (GSR), electrocardiogram (ECG), and front face videos are synchronously recorded. The subjects have reported the duration and category of their emotion experience by means of pressing a button during the experiment and filling out a revised PANAS-X after the experiment, respectively. A statistical analysis of the subjects´ emotion experience self-reports is carried out to verify the effectiveness of the emotion elicitation. In order to explore the distinguish ability of the affective physiological changes of the above-mentioned four emotions, 233 affective physiological features commonly used in literature are extracted to represent the 380 affective physiological data samples. A random forests classifier is applied for quaternary classification of amusement, anger, fear, and sadness, and the overall correct rate is 74.8%.
