Document Summary
Chapter 5: seeing, thinking, and doing in infancy. Preferential-looking technique: a method for studying visual attention in infants that involves showing infants two patterns or two object at a time to see if the infants have a preference for one over the other. If an infant looks longer at one of the two stimuli, the researcher can infer that the baby is able to discriminate between them and has a preference for one over the other. Habituation: procedure involves repeatedly presenting an infant with a given stimulus until the infant"s response to it habituates (declines). Visual acuity: the sharpness of visual discrimination. Infants prefer to look at patterns of high visual contrast: ex. Contrast sensitivity: the ability to detect differences in light and dark areas in a visual pattern. Immaturity of cones: the light-sensitive neurons that are highly concentrated in the fovea (the central region of the retina) and are involved in seeing fine detail and color.
