The document discusses thinking and language. It provides details about concepts, categories, problem solving using algorithms and heuristics, and language development in children. Language involves structures like phonemes, morphemes, and grammar. While animals can communicate, there is no conclusive evidence they have a true language comparable to human language.
6. 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/ Getty Images J. Messerschmidt/ The Picture Cube
7. 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

10. 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
20. 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. ?
21. 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. ?

36. Structuring Language Phrase Sentence Meaningful units (290,500) … meat, pumpkin. Words Smallest meaningful units (100,000) … un, for . Morphemes Basic sounds (about 40) … ea, sh . Phonemes Composed of two or more words (326,000) … meat eater. Composed of many words (infinite) … She opened the jewelry box.

42. When do we learn language? One-Word Stage: Beginning at or around his first birthday, a child starts to speak one word at a time and is able to make family members understand him. The word doggy may mean look at the dog out there .

44. When do we learn language? Longer phrases: After telegraphic speech, children begin uttering longer phrases ( Mommy get ball ) with syntactical sense, and by early elementary school they are employing humor. You never starve in the desert because of all the sand-which-is there.
OBJECTIVE 2 | Describe the roles of categories, hierarchies, definitions, and prototypes in concept formation.
OBJECTIVE 3 | Compare algorithms and heuristics as problem-solving strategies, and explain how insight differs from both of them.
OBJECTIVE 4 | Contrast confirmation bias and fixation, and explain how they can interfere with effective problem solving.
OBJECTIVE 5 | Contrast the representative and availability heuristics, and explain how they can cause us to underestimate or ignore important information.
OBJECTIVE 6 | Describe the drawbacks and advantages of overconfidence in decision making.
OBJECTIVE 7 | Describe how others can use framing to elicit from us the answers they want.
OBJECTIVE 8 | Explain how our preexisting beliefs can distort our logic.
