Document Summary
Both theories argue that there is an objective reality out there to which we respond. Enrichment theory claims that sensory stimulation is often fragmented or confusing. To interpret such ambiguous input, we use our available cognitive schemes to add or enrich it. Our knowledge helps us construct meaning from sensory stimulation we receive. Gibson"s differentiation theory argues that sensory stimulation provides all we need to interpret our experiences. Our task as fledging perceivers is to detect the differentiating information, or distinctive features that enable us to discriminate one form of experience from another. Research methods used to study the infant"s sensory and perceptual. The preference method is a procedure where two objects are simultaneously introduced into the infant"s visual field and the researchers observe which object the infant pays attention to. If the infant looked more at one target than at the other, it was assumed the infant preferred that pattern.
