Visually detectable facial mimicry in response to android facial expressions.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Facial mimicry plays a crucial role in human communication. Previous studies have reported that observing human facial expressions induced spontaneous facial mimicry using facial electromyography (EMG) and video data. A previous study reported that the expressions of an android also elicited such mimicry, as reflected in EMG recordings. However, whether such android-induced mimicry could be visually detectable remains unknown. To investigate this issue, we showed dynamic facial expressions of anger and happiness from the android Nikola via a prompter system to participants. We recorded the EMG of their corrugator supercilii and zygomatic major and videotaped their faces, which were automatically coded for facial actions to evaluate brow lowering and lip-corner pulling actions. Nikola's angry expressions induced stronger corrugator supercilii activity in the EMG and brow lowering in the video data, while happy expressions induced stronger zygomatic major activity and lip corner pulling. These results imply that the facial expressions of humanlike androids can induce visually detectable spontaneous facial mimicry in humans, which could be further utilized to coordinate human-robot interactions.
