Fundamental Processes of Development
1) Maturation- genetic program for growth, nature
2) Imitation
-observe others
-contribute greatly to learning
3) Practice
-circular reaction
-perform activity repeatedly if it produces pleasant feeling
4) Habituation
-boredom
-is interested in novel and exciting object
-when infant is exposed repeatedly to the same object, he becomes less interested
-does not spend time on object that is not interesting
Sensory and Perception Development
-newborn is sensitive to taste and pain
-can discriminate between phoneme
Vision
-least developed sense because its mechanism is the most complex
Visual Cliff
-a test to see if infant can see depth
-an apparatus with a glass platform between two checkerboard platform to see if infant will crawl
across the glass platform
-infants do not pass the visual cliff, which shows they develop sense of depth
Habituation
-a useful test to see if infant show response
-indicate kids can notice difference between new and old objects
-kids have preference over familiar voice, like parents instead of stranger
-sensitive to high pitch sound
-gradually develop far sight vision
-gaze longer at pictures of old pattern
-prefer face over other images
Taste
-suck greatly when infant is exposed to sweet taste
Vision
-use vision to explore environment

Document Summary

Fundamental processes of development: maturation- genetic program for growth, nature, imitation. Perform activity repeatedly if it produces pleasant feeling: habituation. When infant is exposed repeatedly to the same object, he becomes less interested. Does not spend time on object that is not interesting. Least developed sense because its mechanism is the most complex. A test to see if infant can see depth. An apparatus with a glass platform between two checkerboard platform to see if infant will crawl across the glass platform. Infants do not pass the visual cliff, which shows they develop sense of depth. A useful test to see if infant show response. Indicate kids can notice difference between new and old objects. Kids have preference over familiar voice, like parents instead of stranger. Suck greatly when infant is exposed to sweet taste. At age of 1-3, if both eyes are not stimulated, sensory impairment takes place.
