摘要
The development of visual binding in humans has been investigated with psychophysical tasks assessing the extent to which young infants achieve perceptual completion of partly occluded objects. These experiments lead to two conclusions. First, neonates are capable of figure-ground segregation, but do not perceive the unity of a centre-occluded object; the ability to perceive object unity emerges over the first several postnatal months. Second, by 4 months, infants rely on a range of Gestalt visual information in perceiving unity, including common motion, alignment, and good form. This developmental pattern is thought to be built on the ability to detect, and then utilize, appropriate visual information in support of the binding of features into surfaces and objects. Evidence from changes in infant attention, computational modelling, and developmental neurophysiology is cited that is consistent with this view.
