Project description:

Emotion eliciting situations are accompanied by reactions on multiple response variables on subjective, physiological, and behavioral levels. The quantification of the overall simultaneous synchrony of psycho-physiological reactions plays a major role in emotion theories and has received increasing attention in recent research. The research project concentrated on the so?called physiological synchrony/coherence of the emotional reactions during an emotion?eliciting episode. From a psychometric perspective, the reactions represent multivariate non?stationary intra-individual time series. Past approaches did not consider the non-stationarity of the data or only considered average inter-individual levels. Furthermore, empirical results are inconsistent; some studies propose an increase of synchrony during an emotion while others assume a decrease (depending on the physiological signals). To eliminate the disadvantages of the existing approaches, a new time frequency based latent variable approach for the quantification of the synchrony of the responses was developed. The approach was applied to empirical data collected during an emotion-eliciting situations and results showed that the new measure is capable of quantifying the coherence of reactions
