In this short article, we reviewed out studies about development of perception. At first, we explained the findings about material perception in infants. This study showed that the 3- to 4-month-old infants have a striking ability to discriminate slight image changes due to illumination that are not salient for adults. These young infants lose this ability after 5 months of age and then develop an ability to perceive distal surface properties (glossy or matte) at 7–8 months of age. Second, we discussed the relationship between visual illusion and perceptual development. We defined the concept of “pre-constancy” based on the statements of William James. Finally, we defined the characteristic of visual illusion.
