visual perception functions

Form constancy

Ability to identify objects/pictures despite their variation of size, color, shape, position, and texture.

Dysfunctions of this perceptual might cause difficulty recognizing different objects such as cars, clothes, fruits, letters, numbers presented in different colors, sizes, positions, and rewords presented in different contexts such as in the school context and a shop.
