Five experiments examined the integration and competition between body and context objects in locating an object. Participants briefly viewed a target object in a virtual environment and detected whether the target object was moved or not after a 10 s interval. Experiments 1 and 2 showed that performance when both the observer body and the context…

Three experiments investigated whether navigation is less efficient across boundaries than within boundaries. In an immersive virtual environment, participants learned objects' locations in a large room or a small room. Participants then pointed to the objects' original locations after physically walking a circuitous path without vision.…

Four experiments examined the roles of extended surfaces and the number of points in the boundary superiority effect in goal localization. Participants learned the locations of 4 objects in the presence of a boundary, landmarks, or both in an immersive virtual environment by reproducing the locations with feedback. Participants then localized the…
