Document Summary
Sensation: processing of basic info from the external world by the sensory receptors in the sense organs and the brain. Perception: organizing and interpreting sensory info about the object, events, and spatial layout of the world around us. Vision: 40-50% of our mature cerebral cortex is involved in visual processing, used to believe that newborn"s vision was terrible, but it improves rapidly during the first months, research methods since infants can"t respond to instructions: Preferential looking technique (robert fantz): showing infants two patterns or two objects at a time to see of the infants have a preference for one over the other. If an infant has a preference, it means it can discriminate between the two. Ex: pattern vs plain surface it likes the pattern more. Habituation: involves repeatedly presenting an infant with a given stimulus until the response declines.
