Document Summary
Jean piaget"s theory of cognitive development: basic concepts. 4 stages describing qualitatively different ways of thinking. Stages occur in invariant order; no skipping because each stage builds on the previous one. No specialization for learning about specific things (e. g. , number, space) Assimilation: incorporate new info into old scheme. Accommodation: change scheme to accommodate new information. E. g. , scheme = job market is terrible, but then a friend gets a good job. Job market is terrible but friend is an exception (assimilation) What if, 10 friends get good jobs; job market is good, jobs available (accommodation) Major achievement: ability to form mental representations of objects and events. 6 qualitatively different substages - thinking visible (through sensory motor processes: reflexes (0-1 month); schemes = reflexes (e. g. , sucking) Act on different objects, modify through experience. Repeat if pleasurable (e. g. , hand waving, finger sucking, kicking: secondary circular reactions (4-9mths) Apply new motor schemes to external objects. Limitation: object does not exist separate from action.
