Document Summary
Perceptual development: overview, sensation information received by sensory organs, perception interpretation of information received by sensory organs, field of sensation/perception is a key battleground for nativism/empiricism debate. Nature: babies can recognize mother"s sight, sound, and small soon after birth. Nurture: this recognition isn"t actualized until skills are truly developed, and who"s to say that it wasn"t pre-natal: studying sensation and perception in infants, asking babies questions without words for answers without words, preference technique. Directly show baby two projected images that are slightly different. The one the baby looks at more is the one it prefers. Then we can see what types of things babies prefer: habituation/dishabituation technique. The baby may take interest in a novel stimulus. Then we can see how babies take interest in old/new: operant conditioning technique. Training baby to perform certain actions at specific stimulus for reward. When changing the stimulus even slightly, the babies won"t perform action.
