The Role of Biological Motion in Face Perception: Social Judgements of Morphed Expressions Differ from Videos and Photographs.

This study aimed to explore the impact of realistic and artifical facial dynamism on social percpetion. We compared ratings of emotion intensity and genuineness on video recordings, dynamic morphs, and static photographs of happy, sad, fearful, and angry expressions. The experiment was created using the online behavioural experiment builder Gorilla (AnwylIrvine et al., 2020). Each participant completed 144 trials, including 48 trials for each display type (video recording, morph, static), with 12 trials for each emotion (happy, disgust, fear, sadness).
