Abstract
Recent studies suggest that visual information can be integrated over a relatively long delay (> 1500 ms) to form a more complete representation (image-percept integration). The current studies investigated whether this process can occur between stimuli that differ in their spatial properties. Participants viewed two dot arrays that filled all but one space in a square or rectangular grid when combined, and reported the missing space. The arrays differed either in size or orientation. Performance reached a comparable level as when spatial properties were matched. However, such performance depends on at least two processes. We suggest an early encoding process and a later image formation/spatial attention reallocation process are required. The flexibility of the image-percept integration process suggests a strong mechanism to form more complete or detailed representations over time, even when the retinal size and orientation of the scene may change between successive views.
