PSYC1023 Lecture Notes - Lecture 5: Egocentrism, Irreversible Process, Problem Solving
Document Summary
4 stages: sensorimotor stage (birth 2years) Children fail object performance tests (unseen objects still exist) but they fail to understand the ball is still in the box". A theory of mind is developing: preoperational stage (2-7years) Egocentrism (a limited ability to share another view) Animism (a belief all things are living) Children fail conservation task (irreversibility) ex: two different beaker shapes but the liquid is still the same amount. Concentration means a fixation on one property of a concentration task: concrete operation stage (7-11years) Children can apply to do concrete operations ex a>b>c (difficulty: formal operational stage (11years +) They can do the equation a>b>c and get it right. The adolescent can adopt several what if" perspectives. Clearly more complex kind of thinking, the what if" questions mean there is a dramatic change from a child not understanding whether the object still exits. Kohlberg"s stage theory: outlines moral and ethical development.
