  2. 2. Thinking <ul><li>Cognition </li></ul><ul><ul><li>mental activities associated with thinking, knowing, remembering, and communicating </li></ul></ul><ul><li>Cognitive Psychologists </li></ul><ul><ul><li>study these mental activities </li></ul></ul><ul><ul><ul><li>concept formation </li></ul></ul></ul><ul><ul><ul><li>problem solving </li></ul></ul></ul><ul><ul><ul><li>decision making </li></ul></ul></ul><ul><ul><ul><li>judgment formation </li></ul></ul></ul>
  3. 3. Thinking <ul><li>Concept </li></ul><ul><ul><li>mental grouping of similar objects, events, ideas, or people </li></ul></ul><ul><li>Prototype </li></ul><ul><ul><li>mental image or best example of a category </li></ul></ul><ul><ul><ul><li>matching new items to the prototype provides a quick and easy method for including items in a category (as when comparing feathered creatures to a prototypical bird, such as a robin) </li></ul></ul></ul>
  4. 4. Thinking <ul><li>Algorithm </li></ul><ul><ul><li>methodical, logical rule or procedure that guarantees solving a particular problem </li></ul></ul><ul><ul><li>contrasts with the usually speedier–but also more error-prone--use of heuristics </li></ul></ul>
  5. 5. Thinking <ul><li>Heuristic </li></ul><ul><ul><li>simple thinking strategy that often allows us to make judgments and solve problems efficiently </li></ul></ul><ul><ul><li>usually speedier than algorithms </li></ul></ul><ul><ul><li>more error-prone than algorithms </li></ul></ul>
  6. 6. Thinking <ul><li>Unscramble </li></ul><ul><li>S P L O Y O C H Y G </li></ul><ul><li>Algorithm </li></ul><ul><ul><li>all 907,208 combinations </li></ul></ul><ul><li>Heuristic </li></ul><ul><ul><li>throw out all YY combinations </li></ul></ul><ul><ul><li>other heuristics? </li></ul></ul>
  7. 7. Thinking <ul><li>Insight </li></ul><ul><ul><li>sudden and often novel realization of the solution to a problem </li></ul></ul><ul><ul><li>contrasts with strategy-based solutions </li></ul></ul><ul><li>Confirmation Bias </li></ul><ul><ul><li>tendency to search for information that confirms one’s preconceptions </li></ul></ul><ul><li>Fixation </li></ul><ul><ul><li>inability to see a problem from a new perspective </li></ul></ul><ul><ul><li>impediment to problem solving </li></ul></ul>

  11. 11. Thinking <ul><li>Mental Set </li></ul><ul><ul><li>tendency to approach a problem in a particular way </li></ul></ul><ul><ul><li>especially a way that has been successful in the past but may or may not be helpful in solving a new problem </li></ul></ul>
  12. 12. Thinking <ul><li>Functional Fixedness </li></ul><ul><ul><li>tendency to think of things only in terms of their usual functions </li></ul></ul><ul><ul><li>impediment to problem solving </li></ul></ul>
  13. 13. The Matchstick Problem <ul><li>Solution to the matchstick problem </li></ul>
  14. 14. The Three-Jugs Problem <ul><li>Solution: a) All seven problems can be solved by the equation shown in (a): B - A - 2C = desired volume. </li></ul><ul><li>b) But simpler solutions exist for problems 6 and 7, such as A - C for problem 6. </li></ul>
  15. 15. The Candle-Mounting Problem <ul><li>Solving this problem requires recognizing that a box need not always serve as a container </li></ul>
  16. 16. Heuristics <ul><li>Representativeness Heuristic </li></ul><ul><ul><li>judging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes </li></ul></ul><ul><ul><li>may lead one to ignore other relevant information </li></ul></ul>
  17. 17. Heuristics <ul><li>Availability Heuristic </li></ul><ul><ul><li>estimating the likelihood of events based on their availability in memory </li></ul></ul><ul><ul><li>if instances come readily to mind (perhaps because of their vividness), we presume such events are common </li></ul></ul><ul><ul><li>Example: airplane crash </li></ul></ul>
