INTRODUCTION:
Feature extraction for emotion analysis in unconstrained settings where the triggering stimuli are unknown or not clearly defined in time remains an open topic in emotion research. We analysed psychophysiological load patterns using features extracted from multimodal biosignal data, namely: Blood Volume Pulse (BVP), Respiration (RESP), and Electrodermal Activity (EDA).
METHODS:
A total of 15 clinical subjects with breast cancer background and 34 controls were investigated. The task consisted of responding to a questionnaire organized into three moments: 1) neutral; 2) provocative, where a mathematical question was posed; and 3) Life-events reporting. Moment 1 targeted baseline definition, while moment 2 targeted the comparison between the psychophysiological reactions of a stimuli period that was not related to the life-events reporting, and the life-events reporting themselves.
RESULTS:
While standard measurements have shown little inter-/intra-group differentiation, we adopted an extended set with absolute skin conductance amplitude range (ASCAR) and heart rate increments (HRI). The control group has shown higher HRI throughout the different moments, when compared to the clinical group. Between moments 1 and 2, the clinical group has shown a more stable HRI trend, while the control group exhibited a higher variation. Furthermore, ASCAR clearly showed that moment 2 is a higher arousal period for the clinical group when compared to the controls.
CONCLUSIONS:
With an extended set of features we were able to obtain additional insight on the emotional behaviour when comparing clinical subjects with controls, and support the hypothesis that there are differentiated psychophysiological responses between groups.
