In 1890, [[William James]] described the newborn infant's visual world as a blooming buzzing confusion. This view represents a strong [[empiricist]] [[perspective]] that perception develops through learning. It is now known that the newborn's view of the world is not this confusing and also that many important perceptual developments occur within the first year of life. Some principles of looking in infancy include opening the eyes when the [[light]] is not too bright, making broad eye movements until an edge (an area of high contrast) is found, and then continuing to look in the general vicinity of the edge (while making eye movements across the edge). These principles maximize the firing rate of [[neurons]] in the [[eye]] and [[brain]], which may facilitate further visual developments. Several functions of vision are presented in the following paragraphs, including kinds of eye movements, pattern detection, image features, and depth perception.
