Emotion and timing : -How emotional Valence and Arousal affect subjective time estimates for short and long durations
Abstract: Earlier studies suggest that emotion affects long duration estimates of 3-7 seconds and more, but how emotions affect shorter events is not well known. The aim of the thesis was to investigate how emotion, in terms of emotional Valence and Arousal, affects subjective time estimates of short (sub-second) and long (half-a-minute) durations. Participants (N= 26) were exposed to neutral and emotive video clips resembling the International Affective Picture System (IAPS; Bradley, 1995) while making time discrimination judgments (short duration estimates: PSE). Afterwards they made long duration estimates (Long Time Estimates: LTE) and ratings of Valence and Arousal of every video clip. Significant results were that Arousal affected LTE estimates, with longer LTE estimates, the higher the Arousal level. The results indicate that Arousal, but not Valence, affects subjective time perception both of short and long durations.
