Figure 1.

Social vignette. Sample frames from a social vignette that elicited the concept of sharing. When viewing this animation, subjects interpreted the small purple circles as children receiving ice cream cones from a parent or adult figure (large blue circle) (panels A and B). In C and D, the first child drops her ice cream. In E and F, another child shares her ice cream with the first child. In G and H, the third child joins the other two and shares her ice cream, as well.
