Chapter 7 - Piaget I. Piaget’s Theory 4 stages • Cognitive development • Same order in all kids Principles - development proceeds via: Adaptation • respond to environment • Assimilation - incorporating new info into current understanding • Accommodation - changing existing understanding based on new information Structures - organization • Behavioral scheme - organized pattern of behavior • Symbolic scheme - representing events mentally • Operational scheme - mental problem-solving • Stages = different types of logic & cognition • Impetus to advance = inability of old logic to handle new information II. Stages A. Sensorimotor Period (Birth - 2) - using reflexes for beginning problem solving Substage 1 (Birth - 1 month) - refine reflexes • Substage 2 (2-4 months) - primary circular reaction - chance event occurs re stimulating own body - infant finds event pleasing - infant repeats => beginning of intentional behavior • Substage 3 (4-8 months) - secondary circular reaction - learn by chance to make things happen to external objects • Substage 4 (8-12 months) - coordination of secondary schemes - combining 2+ secondary reactions to achieve goal - 1st truly intentional behavior • Substage 5 (12-18 months) - tertiary circular reactions - systematically experiment with objects - try new methods to solve problems - emergence of curiosity • Substage 6 (18-24 months) Symbolic problem-solving - carry out experiments mentally - insight and planning - deferred imitation Object permanence - know objects still exist even when hidden • Summary of Sensorimotor - from reflexive, immobile infants to planful thinkers - form simple concepts/solve problems • Deficiency: no symbolic thought B. Preoperational Period (2-7 years) - beginning use of mental symbols “Preoperational” - not yet thinking logically - magical thinking - focus on deficiencies Ability: Symbolic function • Beginning ability to make one thing represent another • Language • Pretend play 5 Deficiencies - perceive things only 1 way at a time • Egocentrism - no perspective taking • Animism - attribute lifelike qualities to inanimate objects • Phenomenism - think appearance = reality • Centration - consider only one aspect when need to consider 2+ • No conservation - cannot understand that basic properties of object do not change when appearance changes C. Concrete Operational Period (7-11) • Ability = Mental Operations - think logically - about real objects & experiences Additional mental operations: • Reversibility - ability to mentally reverse an action • Seriation - ability to mentally arrange objects along a dimension • Deficiency - cannot think abstractly (concrete = bound to existing objects) Piaget & Education • • • • Construct own knowledge Best = challenging but within ability range Use real objects Active learning (not listening) vs. Doman’s Better Baby Institute D. Formal Operational Period (12+) • Ability = Abstract thought - mental actions performed on ideas & propositions - reason logically - not necessarily based on reality Hypothetical-Deductive Reasoning • all factors that could affect an outcome • generate hypotheses • test the hypotheses in orderly fashion Personal & social implications Positive • Apply problem-solving to life choices • Consider possibilities • Form stable identity • Take others’ perspectives Problematic • Anger at world’s illogicality • Frustration with those in charge -> all-or-none thinking • Greater self-consciousness: Egocentrism vs. Social perspective-taking We don’t all reach formal operations • Intellectual abilities • Formal schooling Maybe we have reached but don’t demonstrate ability III. Criticisms of Theory • Competence vs. performance 1. Tasks may be too difficult 2. Low motivation to perform 3. Poor memory • Following social conventions Socially appropriate responses vs. understanding • Training Piagetian Concepts Necessity of maturation vs. Research on teaching concepts (Gelman) • Lack of Consistency within Stages Children perform at different levels • Timing of Stages/Skills Piaget’s ages not always appropriate But sequence of abilities is supported IV. Neo-Piagetians 1.Qualitative changes in thinking - At 2, 7, 11 - Retain the 4 basic stages & their sequence - Still no good explanation of how/why children advance 2.Performance varies by task
