The Effects of Scene Category and Content on Boundary Extension

Boundary extension is a robust scene perception phenomenon in which observers erroneously remember seeing portions of a previously viewed scenes beyond the image boundaries.The effect is strong and reliable, and has been demonstrated for a wide variety of observers.Various studies have shown that boundary extension is distinct from amodal completion and subject to certain pictorial constraints that define an image as being a "scene."We examine here how scene content influences boundary extension.We demonstrate that the presence of foreground objects appears to enhance the extension effect, and that scene complexity also plays a role in determining the magnitude of the extension effect.These results are discussed with regard to the scene context hypothesis of boundary extension and recent results in scene perception.
