The Second Database of Emotional Videos from Ottawa (DEVO-2): Over 1300 brief video clips rated on valence, arousal, impact, and familiarity.
Article in Behavior research methods, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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.
