"Boundary extension" is a memory illusion in which observers remember seeing more of a scene than was shown. Two experiments tested the possibility that this spatial distortion occurs soon after picture perception. In Experiment 1, undergraduates viewed close-up or wide-angle photographs for 250 ms or 4 s. Recall and recognition tests followed. Brief presentations yielded as much boundary extension as long presentations. In Experiment 2, picture triads were presented at a rate of 333 ms per picture with no inter-stimulus interval. After 1 s, one picture repeated and remained in view while subjects indicated whether it was the same or showed more or less of the scene. Even when conditions mimicked a series of rapid eye fixations, boundary extension occurred. The presentation of a picture appears to activate a perceptual schema that allows observers to understand it in a larger context and this process distorts memory for its actual boundaries. @ 1996 Academic Press.
