For example, a robin is a prototype of a bird, but a penguin is not. Triangle (definition) Bird (mental image) Daniel J. Cox/ Getty Images J. Messerschmidt/ The Picture Cube
Categories Once we place an item in a category, our memory shifts toward the category prototype. A computer generated face that was 70 percent Caucasian led people to classify it as Caucasian. Courtesy of Oliver Corneille

Algorithms ,[object Object],S P L O Y O C H Y G If we were to unscramble these letters to form a word  using an algorithmic approach, we would face  907,208 possibilities.
Heuristics Heuristics are simple, thinking strategies that allow us to make judgments and solve problems efficiently. Heuristics are less time consuming, but more error-prone than  algorithms. B2M Productions/Digital Version/Getty Images
Heuristics ,[object Object],S P L O Y O C H Y G S P L O Y O C H G Y P S L O Y O C H G Y P S Y C H O L O G Y Put a Y at the end, and see if the word begins to make sense.

Mental Set ,[object Object]
Functional Fixedness A tendency to think only of the familiar functions of an object. Problem: Tie the two ropes together.  Use a screw driver, cotton balls and a matchbox. ?
Functional Fixedness Use the screwdriver as a weight, and tie it to the  end of one rope. Swing it toward the other rope to tie the knot. The inability to think of the screwdriver as a weight is functional fixedness. ?

Representativeness Heuristic ,[object Object],Probability that that person is a truck driver is far greater than an ivy league professor just because there are more truck drivers than such professors. If you meet a slim, short, man who wears glasses and likes poetry, what do you think his profession would be? An Ivy league professor or a truck driver?
