An emotionally involved event may subsequently appear shorter than an event of relative indifference for people. How are time-related behaviors influenced while people are emotionally affected? The purpose of this study was to test if ongoing estimates and retrospective reports of duration are similarly affected by emotional states. To test, 30 s emotional video clips were rated for Valence and Arousal by six participants. The videos were then used in a timing experiment where a new set of participants (twenty-five persons) carried out a repetitive motor timing paradigm while watching the videos and subsequently reported the perceived duration of the clip. In each of ten trials, participants first synchronized to a 700 ms isochronous interval with their index finger, and then continued unsupported as five different video clips were played in sequence, with each clip lasting 30s. At the end of each trial, participants reported their retrospective duration judgment of every video clip, and rated every video chip for Valence and Arousal. Emotion ratings suggested that the videos affected the subjects’ emotional states. Repetitive motor timing was not reliably affected by emotional states. Instead, retrospective reports of durations were affected by emotional states such that the durations estimated under high arousal conditions were significantly longer than those under low arousal conditions. The difference in results between repetitive motor timing and retrospective reports may be accounted for by the interval of 700 ms being too short to be cognitive-related.
