| summary | Humans intuitively expect physical objects to obey core principles, including continuity (objects follow spatiotemporally continuous paths), and solidity (a solid object cannot pass through another solid object). Research in adults suggests that the degree to which these principles are embedded in visual processes may differ: continuity may be more strongly and less flexibly represented in vision than solidity.
To test this hypothesis, we asked participants to track an object’s location in continuity and solidity events, where physical principles were sometimes violated. Participants' accuracy dropped more with continuity violations than with solidity violations, possibly reflecting stronger prior expectations for the respect of continuity. This result was obtained in experiments both in lab and online, with videos of real objects and 3D animations.
Furthermore, in lab experiments, participants learned more to expect solidity violations, while continuity violations remained more surprising. Online participants reached higher accuracy much more quickly, making the differences between principles non-significant. |
