We present an analysis of psychophysiological measurements of emotional states. Data comes from experiments that were performed in the frame of Cyberemotions project [1] and concerned people’s emotions observed during discussions on online forums. Each participant saw IAPS pictures, read and wrote posts on an artificial forum while being connected to devices measuring his/her physiological states. Analysis of collected signals (such as EKG, facial muscles activity, skin conductance, etc.) and written responses in emotion questionnaires was the main part of the study. We analyzed an emotional response for a given picture or message, and correlation  between the signal and a subjective rating of participants. Our methods combine several different approaches – statistical, based on signal analysis, and elements of information theory.
