Document Summary
Sensation: information received by sense organs and transmission of that information to the brain. Perception: interpretation of information received by sense organs. Field of sensation/perception is a key battleground for nativism/empiricism. Babies hear and see and taste very well at birth. All the skills that babies need they are born with. Through experience infants develop until they achieve adult like abilities. Have a system which we inherit but we have to develop them over time. Sensation and perceptual processes are the means by which people receive, select, modify and organize stimulation from the world. An investigator presents 2 stimuli to a baby, then the investigator records the baby"s responses such as heart rate, facial expression or head movement. If the baby consistently responds differently to the 2 stimuli, the baby must be distinguishing between them. Someone looks to see which image the chimps looks at more. This is what the chimp can see.
