Infants are neurologically wired to seek out patterns in their visual field.
How do they do that? Imagine trying explain to an infant to raise his finger when he thinks the room gets brighter.
Of course they don't do it that way. What they do is to wire the infant's pacifier to register a change in sucking behavior. This change occurs automatically when the child perceives a change in his environment, in this case brightness.
The third is that anyone would consider this information worth talking about. And yet it is important, because it sets the stage for the next perceptual process...Pattern Preference.
2. Pattern Preference: If an infant is gazing at an opaque surface, and some kind of pattern is introduced into his visual field, the child is "wired" neurologically to seek the pattern out and fixate on it. It can be demonstrated that, although the pattern may have no meaning, the child is processing the image.
