[5] The stages of feature integration theory. Treisman distinguishes between two kinds of visual search tasks, "feature search" and "conjunction search".

This type of visual attention problem is one of three major components (the others being optic ataxia and optic apraxia) of Bálint's syndrome, an uncommon and incompletely understood variety of severe neuropsychological ...
Peek-a-boo is a prime example of an object permanence test. [6] In Piaget's formulation, there are six stages of object permanence. [7] These are: 0–1 months: Reflex schema stage – Babies learn how the body can move and work. Vision is blurred and attention spans remain short through infancy.
