What is thought? There are basically two types of thought… 1.Concepts (schemas)…usually based on prototypes. 2.Images Our concept of men may include all of the following guys…. But they are based on our prototype (ideal) male…..
Algorithms A rule that guarantees the right solution to a problem. Usually by using a formula. They work but are sometimes impractical.
Heuristics (hew – RIS- tik) A rule of thumb that generally, but not always, can be used to make a judgment to solve a problem. It is fast, but is… Prone to errors Two major types of heuristics….
Representativeness Heuristic Judging a situation based on how similar the aspects are to the prototypes the person holds in their mind. Ex. someone with glasses is nerdy, or a blonde is not smart. If I tell you that Sonia Dara is a Sports Illustrated swimsuit model, you would make certain quick judgments (heuristics) about her…like about her interests or intelligence. She is an economics major at Harvard University. Who went to Harvard? My friend Dan is a smart dude, but did not go to Harvard (but he looks like he did). Extreme Makeover: Criminal Court Edition Extreme Makeover: Criminal Court Edition
Availability Heuristic Judging a situation based on examples of similar situations that initially come to mind. Vivid examples in the news often cause an availability heuristic. Which place would you be more scared of getting mugged or even murdered? The Bronx, NY Gary, Indiana The crime rate of Gary, Indiana is MUCH higher than the Bronx. But when you think of crime, which town comes to mind? I realize the Bronx picture is misleading.
Representative any stereotypes – blondes are dumb, irish are leprechauns, germans are not funny, muslims are terrorists, Availability shortcut based on your available information - the best pizza and wings are from my hometown of Clinton Township - "have you tried any others?" of course not, the best is in Buffalo!
Heuristics can lead to Overconfidence… Our confidence is not a good indicator of how right we are. Belief Perseverance- maintaining a belief even after it has been proven wrong. Belief Bias- People will tend to accept any and all conclusions that fit in with their systems of belief, without challenge or any deep consideration of what they are actually agreeing with. God is love. Love is blind Ray Charles is blind. Ray Charles is God.
Hurdles to problem solving
Mental set a.k.a. rigidity The tendency to fall into established thought patterns. Some examples are…. Using no more than four lines, can you connect all nine dots without lifting your pencil from the paper?
To overcome mental sets you must think outside the boxliterally!
Mental Set Example Assume that youre the engineer of a passenger train. At the first station, 20 passengers get on. At the next station, 5 passengers get off and 15 get on. At the next station, 10 passengers get off and 12 get on. At the next station, 7 get off and 5 get on. At the next station, 8 passengers get off and 3 get on. 1. How old is the engineer of the train? 2. How many stations were there? 3. How many passengers are left on the train? 4. Altogether, how many passengers have gotten off the train since the first station?
Functional Fixedness The inability to see a new use for an object. Think of as many uses as you can for a ……
Confirmation Bias We look for evidence to confirm our beliefs and ignore evidence that contradicts them. For example, if one believes that all Italians are in shape and go tanning, then they turn on MTV. Look…I knew it was true!!! But is it really?
Framing 90% of the population will be saved with this medication…..or 10% of the population will die despite this medication. You should not drink more than two drinks per day….or You should not drink more than 730 drinks a year. Look at the following question and think about how the question is worded may effect the way it is answered. How can businesses become more socially responsible? The way a problem is presented can drastically effect the way we view it.
Framing Examples A surgeon bragging about a 98% survival rate OR A surgeon bragging about a 2% death rate Ground beef being 20% fat OR 80% lean. Condoms have a 95% success rate in stopping HIV infections. (90% college students rate condoms as effective) Condoms have a 5% failure rate (4% rate condoms as effective)
CREATIVITY Almost impossible to define. Little correlation between creativity and intelligence. Convergent Thinking versus Divergent Thinking
Convergent – What is the area of a triangle that is 3 feet wide at the base and 2 feet tall? – Erica is shorter than Zoey but taller than Carlo, and Carlo is taller than Jared. Who is the second tallest? Divergent – What objects can you think of that begin with the letter BR? – How could discarded aluminum cans be put to use?
Language can be…..
All languages contain…. Phonemes The smallest units of sound in a language. English has about 44 phonemes. Morphemes The smallest unit of meaningful sound. Can be words like a or but. Can also be parts of words like prefixes or suffixes…ed at the end of a word means past tense. How many phonemes does platypus have?
23 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.
Grammar The rules of a language. Syntax: the order of words in a language. Is this the White House or the House White?
Language Acquisition Stages that we learn language… 1.Babbling Stage 2.Holophrastic Stage (one word stage) 3.Telegraphic Speech Stage (2-word ) After the telegraphic stage we get overgeneralization.
26 When do we learn language?
How do we learn language?
Social Learning Theory B.F. Skinner from the Behaviorist School Baby may imitate a parent. If they are reinforced they keep saying the word. If they are punished, they stop saying the word.
Chomskys Theory (nativist theory) We learn language too quickly for it to be through reinforcement and punishment. Inborn universal language acquisition device
Whorfs Linguistic Relativity The idea that language determines the way we think. The Hopi tribe has no past tense in their language, so Whorf says they rarely think of the past.

Searching for analogies: A teacher had 23 pupils in his class. All but 7 of them went on a museum trip and thus were away for the day. How many students remained in class that day? Susan gets in her car in Boston and drives toward New York City, averaging 50 miles per hour. Twenty minutes later, Ellen gets in her car in New York City and starts driving toward Boston, averaging 60 mph. Both women take the same route, which extends a total of 220 miles between the two cities. Which car is nearer to Boston when they meet? 7 Susan & Ellen are exactly the same distance from Boston when they meet
The maker doesnt want it, the buyer doesnt use it, the user doesnt see it. How can you physically stand behind your father while he is standing behind you? A coffin Stand back to back
A man left home one morning. He turned right and ran straight ahead. Then he turned left. After a while, he turned left again, running faster than ever. Then he turned left once more and decided to go home. In the distance he could see two masked men waiting for him. Who were they? What occurs once in every minute, twice in every moment, yet never in a thousand years? The umpire & the other teams catcher The letter M You have two coins worth 30 cents. One of them is not a quarter. What are the two coins? A nickel & quarter
