Stages of Intellectual Development
1. Sensorimotor stage (birth - 2 years old)--The child, through physical interaction with his or her environment, builds a set of concepts about reality and how it works. This is the stage where a child does not know that physical objects remain in existence even when out of sight (object permanence).Stages of Development
3. Concrete operations (ages 7-11)--As physical experience accumulates, the child starts to conceptualize, creating logical structures that explain his or her physical experiences. Abstract problem solving is also possible at this stage. For example, arithmetic equations can be solved with numbers, not just with objects.Stages of Development
Make a choice: There is a disease that is likely to kill 600 people. Would you prefer a program that will definitely save 200 people or one that has a 1/3 probability of saving all 600 and a 2/3 chance of saving none?
Make a choice: You have available a program in which 400 people will definitely die and a program in which there is a 1/3 probability of nobody dying and a 2/3’s probability that all 600 will die. Which to you choose?
