Abstract
Recent advances in user interface of web browsers enabled users to alter playback speed during watching various types of video lectures and streaming services. Previous studies demonstrated that degree of comprehension in lecture content watched at 1.6x speed did not differ from that at 1.0x speed. The present study examined whether increasing playback speed caused any impacts on emotional aspect in mood evoked after watching short videos. Three types of emotional video conditions (anger, sadness, and joy) were employed. Participants watched one of the three types of emotional videos at 1.0x or 1.6x speed and reported valence and arousal level by using the Affect Grid before/after video watching. For each emotional video condition, no main effect of playback speed was observed by 2 (playback speed: between-subjects) x2 (before/after: within-subjects) mixed subjects ANOVAs on valence or arousal level. These results indicate that speed watching does not impair viewing emotional experience.
