Development Cognitive Development Piaget and Cognitive Development • Jean Piaget (1896-1980) Swiss Psychologist. • He was intrigued by the fact that children of different ages made different kinds of mistakes while solving problems. • They are not “little adults”. • He believed that children move through 4 cognitive stages. The Four Stages 1. SENSORIMOTOR Birth-2 years Experience world through actions (touch-sight) and on innate motor responses to stimuli. Very little thinking involved. Object Permanence- The realization that an object continues to exist even if you can’t see or touch it. Object Permanence Object Permanence 2. Preoperational 2-6 years 2. preoperational 2-6 years Representing things with words & images but no logical reasoning. Pretend Play Egocentrism- The tendency to view the world from one’s own perspective without recognizing that others may have different points of view. (3 mountains problem) They do not understand conservation - The understanding that physical properties of an object remain unchanged despite changes in appearance. The 3 Mountains Experiment 3. Concrete Operational 6-11 years Children can perform mental operations on tangible objects or events & begin logically reasoning, but still is incapable of abstract thought. 4. FORMAL OPERATIONAL 11-adulthood Abstract reasoning PSYCHOSOCIAL DEVELOPMENT Erik Erikson proposed that humans develop a personality in eight psychosocial, or psychological and social, stages. During each stage, we experience a particular psychosocial crisis that will be resolved either positively or negatively, and each outcome will have an effect on our ability to deal with the next one. PSYCHOSOCIAL DEVELOPMENT The most important “crisis” to solve is the “Identity Crisis” that occurs during adolescence. Erikson argued that in order to come to a sense of identity, teens must engage in exploration. They must try out new ways of thinking and behaving. This explains the many "phases" that teens go through as their attempts at exploration. morals Concerned with the principles of right and wrong behavior and the goodness or badness of human character. moral development Lawrence Kohlberg believed...and was able to demonstrate through studies...that people progressed in their moral reasoning (their bases for ethical behavior) There are 3 main Levels. Pre-conventional, Conventional & Post-conventional moral development the heinz dilemma A woman was near death from a special kind of cancer. There was one drug that the doctors thought might save her. It was a form of radium that a druggist in the same town had recently discovered. The drug was expensive to make, but the druggist was charging ten times what the drug cost him to produce. He paid $200 for the radium and charged $2000 for a small dose of the drug. The sick woman's husband, Heinz, went to everyone he knew to borrow the money, but he could only get together about $1,000 which is half of what it cost. He told the druggist that his wife was dying and asked him to sell it cheaper or let him pay later. But the druggist said: "No, I discovered the drug and I'm going to make money from it." So Heinz got desperate and broke into the man's store to steal the drug for his wife.
