Boundary extension (BE) refers to the phenomenon whereby a close-up photograph of a scene is remembered as if it extended beyond the boundaries of the photograph. The present study investigated the relationship between how close-up a stimulus image appeared (perceived closeness) and the magnitude of BE for the image. In Experiment 1, we showed that the perceived closeness of the image depended systematically on both the physical and perceived sizes of the object in the image. In Experiment 2, we investigated whether the systematic relation between object sizes and perceived closeness was reflected in the magnitude of BE. The results showed that images needed to be close-up at the presentation phase, but that the degree of perceived closeness was not critical for producing greater BE. Additionally, neither physical nor perceived object sizes significantly contributed to the magnitude of BE. In view of the perceptual schema hypothesis that assumes that spatial extrapolation results from the activation of a perceptual scene schema, these findings suggest that the extent of extrapolation beyond the given view does not correlate with the degree of perceived closeness.
