1 1 Thinking and Language Chapter 10 2 Concept The mental grouping of similar objects, events, ideas, or people. There are a variety of chairs but their common features define the concept of a chair . 3 Category Hierarchies We organize concepts into category hierarchies. Courtesy of Christine Brune 4 Development of Concepts We form some concepts with definitions. For example, a triangle has three sides. Mostly, we form concepts with mental images or typical examples ( prototypes ). For example, a robin is a prototype of a bird, but a penguin is not. Triangle (definition) Bird (mental image) Daniel J. Cox/ Gety Images J. Messerschmidt/ The Picture Cube 5 Problem Solving There are two ways to solve problems: Algorithms: Methodical, logical rules or procedures that guarantee solving a particular problem. 6 Algorithms Algorithms, which are very time consuming, exhaust all possibilities before arriving at a solution. Computers use algorithms. 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.

2 7 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/Gety Images 8 Heuristics Heuristics make it easier for us to use simple principles to arrive at solutions to problems. S P L O Y O C H Y G S P L O Y O C H G Y Put a Y at the end, and see if the word begins to make sense. 9 Insight Insight involves a sudden novel realization of a solution to a problem. Humans and animals have insight.

The time between not knowing the solution and realizing it is 0.3 seconds.
