Abstract
We introduce an updated set of video clips for research on emotion and its relations with perception, cognition, and behavior. These 1380 brief video clips each portray realistic episodes. They were selected to portray situations that vary widely in emotion. Undergraduate students rated the videos on emotional valence, arousal, impact, and familiarity. As expected, valence and arousal ratings were related in a U-shaped function, and arousal and impact were positively linearly associated with one another. Ratings of familiarity were near zero on average, verifying that the clips came from obscure sources. k-means cluster analysis revealed that they could be grouped by valence, arousal, and impact for selecting subsets for future studies. We also provide estimates of motion, luminance, contrast, and visual complexity to facilitate selection. The videos can be used in similar ways to static images but have the advantage of being dynamic and thus more ecologically valid.
期刊介绍：
Behavior Research Methods publishes articles concerned with the methods, techniques, and instrumentation of research in experimental psychology. The journal focuses particularly on the use of computer technology in psychological research. An annual special issue is devoted to this field.
