Piaget's Theory: Stage 4 - Formal Operations = 11-adulthood
- move from being able to consider only the concrete concepts to being able to consider abstract concepts
- deductive logic/reasoning - goes from ALL (general) to ONE (specific)
- e.g. "sharks are fish" and "all fish have fins" = "sharks have fins"
- can consider hypothetical situations
- can consider hypothetical even if doesn't make any sense
- Pendulum Problem:
- have been given different lengths of a cord and weight, task is to work out which factor is most important in determining speed
- problem = systematic variation vs trail and error
