Turning The Partial-Closed World Assumption Upside Down
The partial-closed world setting provides an intermediate ground between open-world and closed-world settings.

Whereas convex refractive objects invert the orientation of the horizon so the sky appears beneath the ground plane, convex specular surfaces preserve the orientation of the horizon so the sky appears above the ground. Here, we ...

The information available in the body stimulus was manipulated. The presence and magnitude of inversion effects were compared for body parts, ...
