Abstract
Boundary Extension (BE) is a widely reported memory phenomenon in which people recall seeing a wider-angle view of a scene than was actually seen. This effect is thought to be due to fundamental perception processes inherent in scene viewing that cause these complex stimuli to be remembered differently than simple objects. Certain image manipulations used in previous work suggest that another memory effect called normalization may be affecting responses depending on the characteristics of the pictures contents and how they are presented to participants. This study examines the interaction of these two effects for abstract scenes, characterized by a lack of long-term memory associations with the image contents, and for scenes depicting the real world. Experiment 1 verifies the co-occurrence of BE and memory normalization for some images. Experiment 2 is the first known scene memory experiment using intact pictures of the real world that does not show BE.
