The Clay Hand Illusion and the Embodiment of Unfeasible Objects.

abstract：:In a series of three experiments, observers judged the perceived relative depths of small probe dots, which could be presented in empty space or attached to a smoothly curved surface. Discriminations of ordinal depth were found to be more precise than discriminations of depth intervals. The amount of separation in the...
