Developmental theory of cognitive development (in stages): how intelligence develops1. Sensorimotor stage (birth—2 years): cognitive development is parallel with motor development. Not uncommon for children with motor delays to also have cognitive delays Milestone: when child begins to be able to imitate behaviors, bc they're forming a mental representation of actions and repea ting it, showing dev. of internal representations of behavior Object permanence—forming a mental representation of the object2. Pre-operational stage (2—7 years): Thinking is rigid, typically lacking in logic and egocentric. (Higher level of cognitive ability to think abstractl y and think in someone else's perspective.) Development of language—nothing more than amplified/vocalized thought Common core criticism: reason/logic skills don't work for kids in preoperational stage3. Concrete operational stage (7—12 years): Thinking becomes more logical, flexible, organized. Somewhat less egocentric. Master the concept of conservation—able to understand that things have I changing, abstract propertiesAbstract thinking is still difficult4. Formal operations (12—adulthood): thinking is flexible, logical, abstract. Not everyone will reach this stageAccommodation and AssimilationLawrence Kohlberg used Piaget's theories to explain moral developmentKohlberg's dilemma: a druggist sells the cure for a woman's cancer at 10x the cost of the production, and a man couldn't affo rd it for his wife even after collecting money from friends. The druggist refused to sell it cheaper or accept installment payments, so the man stole the drug from his lab. Was this the right thing t o do? Why or why not?Morality develops in 3 stages:1. Pre-conventional morality (~2-5) Stage 1: punishment/obedience Stage 2: rewards2. Conventional morality(~5-10) Stage 3: good intentions/good behavior Stage 4: obedience to authority3. Post-conventional morality(~10-adult) Stage 5: diff. Btw moral and legal right. Recognition that rules should sometimes be broken Stage 6: indiv. Principles of conscience. Takes account of likely views of everyone affected by a moral decision.Jean Piaget: 4/9/14Wednesday, April 09, 20144:55 PM Psychology Page
