Abstract
Comparisons between modally and amodally completed
regions show that perceptual filling-in is not merely the ignoring
of absences. Illusory filled-in colour arises for modal completion,
but not for amodal completion in comparable displays. We find that
attention spreads automatically to modally but not amodally
completed regions from their inducers, revealing a functional
effect of filled-in colour.
