Fluctuation-dissipation relations in physiological data collected during emotional stimulation — •Jan Chołoniewski, Anna Chmiel, and Janusz Hołyst — Faculty of Physics, Center of Excellence for Complex Systems Research, Warsaw Univeristy of Technology, Poland

We present results of our search for fluctuation-dissipation relations in physiological data (i.e. phasic skin conductance, facial EMG). Data comes from experiments that were performed in the frame of Cyberemotions project [1] and concerned people's emotions observed during experiencing emotional stimuli (i.a. IAPS images). For the sake of this study, we also tried out several approaches for quantifying response function and fluctuations in physiological signals. Because of signals' nonlinearity and non-stationarity part of fluctuations analysis was based on time-frequency methods and signals decomposition (such as Empirical Mode Decomposition, Discrete Wavelet Transform).
