PSY 211 Lecture Notes - Lecture 22: Functional Fixedness
Document Summary
Problem - consists of some initial state in which a person begins and a goal state that is to be attained, plus a non-obvious way of getting from the first to the second. Well-defined - completely specified starting cognitions, goal state, and methods for achieving the goal. Ill-defined - some aspects are not completely specified, lots of factors. How to get from initial state to the goal state. Think about how you"re going to go through with solving the problem. Form a representation > construct a plan > execute plan > checking/evaluation > reformulate. Re-doing and re-formulating it depends on the situation. Problem space - whole range of possible states and operators, only some of which will lead to the goal state. Retrieve a representation of a problem from memory that is similar to the problem you currently face. Solve the new problem using the solution to the old problem.
