    "title": "Causal Action: A Fundamental Constraint\non Perception of Bodily Movements",
    "subtitle": null,
    "abstract": "Human actions are more than mere body movements. In\ncontrast to other dynamic events in the natural world, human\nactions involve mental processes that enable willful bodily\nmovements. We reported two experiments to demonstrate that\nhuman observers spontaneously assign the role of cause to\nrelative limb movements, and the role of effect to body motion\n(i.e., the position changes of the body center of mass) when\nobserving actions of others. Experiment 1 showed that this\ncausal action constraint impacts people’s impression on the\nnaturalness of observed actions. Experiment 2a/b revealed that\nthe causal constraint guides the integration of different motion\ncues within a relational schema. We developed an ideal\nobserver model to rule out the possibility that these effects\nresulted from the learning of statistical regularity in action\nstimuli. These findings demonstrate that causal relations\nconcerning bodily movements play an important role in\nperceiving and understanding actions.",
