Cognitive Development - Lecture 2 Piaget's theories – Wednesday, May 8, 2012 Video: Human Development 2 1/2 years − children learn how to learn in the first two years of life − Example of habituation: A pattern or sound is shown to a baby. The baby may demonstrate physiological changes through sucking, motor response, heart rate, or alertness – all of which can be measured. Eventually the baby will show disinterest in the patterns or sounds because they are familiar with it (This is learning) − Dishabituation: When a new pattern or sound (stimuli) is demonstrated they show new physiological response The baby's demonstrates learning through: − detect change − discriminate between stimuli − remember a stimulus Gustatory: Prefers the smell of mother over another woman Olfactory: Likes for vanilla and banana, dislikes for shrimp. Reacts to sweet, salty, bitter, sour, and fatty Visual: Prefers certain colours over others. Prefer faces to other shapes. Prefers complex shapes over simple shapes. Prefer pattern vs. Solid colours. Somatosensory: Prefers gentle rubs over pinch Auditory: Prefers female voice over a males Babies will turn away or retract from an over stimulating environment because there is an overload in perceptual and conceptual capacities. Learning how to Learn: − random manipulation − gross exploration − minute examination − practice − experiences − put information to use Babies will manipulate objects using all senses to understand it (Learning). They will put objects in their mouth, shake it, throw it and do so in a repetitive manner -> Ex. The toys keys Piaget's 4 Stages Sensorimotor Stage Substage 1 (0-1 month) – sucking, looking, head turning (innate behaviours) modify and are modified by the environment Substage 2 (1-2 months) – repetitive behaviour to acquire information. Coordination movement of sucking to the mouthTemporal Substage 3 (4-8 month) - repetitive behaviour that creates pleasant sights and sounds, imitate behaviour of others Substage 4 (8-12 months) – object permanence, anticipate events such as parents leaving substage 5 (12-18 months) – discovering the world, varies actions rather than repetitive and observing the effect, trial and error through puzzles, understanding use of objects (cups) substage 6 (18 months) – symbolic thinking, forms mental pictures before choosing outcomes, deferred imitation of a action they have seen before at another time, pretending All stages are to adapt to environmen
