The Parameters Of Power Performance Study Emotional Response Time

Emotion unfolds over time, and so it involves many changes in "temporal dynamics". By far most traditional emotion researches have focused on how to induce emotions and then test their related effects on other cognitive processes, while paying little attention to the important parameters of emotional temporal dynamics, such as the latency of the onset and emotion recovery, etc, and thus left doubts on the reliability and stability of thei research findings. Therefore exploring temporal dynamics of emotion would be very necessary and fundamental to future emotion studies.Prior studies on temporal dynamics of emotion either focused on single parameters, such as the latency of emotion recovery, or just attended to changes in physiological response or subjective feeling, isolatedly. What’s worse, asking participants to recall their emotional feeling after a certain time period is not suitable to examine "emotion dynamics" in a larger time frame.Based on existing findings on temporal dynamics of emotion, the present study explored three important parameters of emotional temporal dynamics-the latency of the onset, the peak, and recovery-by asking participants to view two edited film clips (amusing vs sad), while online data of subjective feeling and physiological reactivity was recorded.Pre-study1examined whether the two edited film clips can induce the targeted emotions (amusement vs sadness) and whether the two film clips were comparable in terms of online rated arousal analysis. Post film-viewing self report data were collected, and the validity of online rated data was also tested.Pre-study2further validated the emotional effects of the two standardized film clips in terms of online subjective feelings and physiological responses, and the validity of online rated data was also tested. A preliminary analysis of subjective emotion recovery was conducted.The Formal study was finally conducted on the basis of the prior two studies, and a full anay lysis of the three important parameters of emotional temporal dynamics (the latency of the onset, the peak and recovery) in terms of both continuous subjective emotional feeling and physiological response was made. There were the following three major findings:1) For the latency of the onset, sadness aroused faster than amusement in subjective emotional feeling and heart rate activity, which were6-9s,0-3s and9-12s, more than6s after the film clip began, respectively. However, amusement appeared earlier than sadness in skin conductance response and finger pulse amplitude reactivity, which were3-6s, more than6s and0-3s,3-6s after the film clip began, respectively.2) For the latency of recovery, amusement recovered faster than sadness in subjective emotional feeling, which were3-4m and2-3m after the film clip ended, respectively. However, there were no significant difference between recovery of sadness and amusement in heart rate activity, skin conductance response and finger pulse amplitude reactivity, which were0-1m,4m and2-3m after the film clips ended.3) For the latency of the peak, except in heart rate activity, the peak of sadness in subjective emotional feeling, skin conductance response, and finger pulse amplitude reactivity arrived earlier than that of, amusement. Specifically, sadness and amusement reached their peak in subjective emotional feeling, heat rate activity, skin conductance response, and finger pulse amplitude reactivity were155s,113s,139s,127s, and121s,99s,74s,95s, respectively.
