Unit 7B, Thinking, Problem-Solving, Creativity, and Language(Updated for 2011; goes with Chapter 10 in 2007 book)

I. Thinking, 298 Also called Cognition: mental activities associated with processing, understanding and communicating

1. Metacognition: knowledge of what strategies to apply, when and how so that new knowledge can be developed

2. syllogism: deductive reasoning in which a conclusion is derived from two premises

Ex. a. Every virtue is laudable b. kindness is a virtue

c. Therefore, kindness is laudable

A. ConceptWhat are the functions of concepts? In order to simplify the world we create these

Mental groupings of similar thingsFor Piaget (see Unit 9) the basic unit of mental organization was a schema, a model upon which to organize thinking.Ex: chair represents baby’s high chair, dentist’s chair, reclining chairTo simplify things we form hierarchies.Some are formed by definition.

1. Prototype includes all the features we associate with the best representation of an object

Ex: a robin more closely resembles our bird prototype

B. Solving Problems 3001. Algorithm a logical procedure used to solve a problem

a. slower, but less likely to lead to mistakesEx: unscramble the letters in SPLOYOCHYG to find the word

2. Heuristic using a rule of thumb strategy for problem solving and decision makingEx: would not solve SPLOYOCHYG example by trying YY combination3. Insight a flash of inspiration gives you the solution; occurs in the temporal lobe

(see also page 236, insight learning)4. Wolfgang Kohler demonstrated that chimps use insight (1925).

Divergent v. convergent thinking: searching for multiple answers v. searching for the one correct answer; divergent is more related to creativityBrainstorming: a group leader defers to all members for free, uncritical expression of ideas by members of a group to more effectively solve a problem

IDEAL problem solving: identify the problem, develop solutions, evaluate ideas, act (apply the solution), look back (evaluate)

Deduction v. Induction: Deducing: going from the general set of facts to specific conclusions. Induction: going from the specific to a general statement.

Creativity, 301What is creativity and what fosters it?Creativity: the ability to produce new ideas that are usefulDivergent thinking: thinking of more than one possible answerConvergent thinking: intelligence tests and most school work requiring one, correct answer.Five components of creativity identified by Robert Sternberg:

a. expertiseb. imaginative thinking skillsc. venturesome personality new and risky endeavors are appealingd. intrinsic motivation doing something because it is inherently interesting (see Unit

8A)e. creative environmentTeresa Amabile’s experiment showed that people are more creative when they are not graded on their work.To promote creativity managers should activate employees’ intrinsic motivation

Creative thinking is helped by the two-track mind and parallel processing, the mind working on more than one thing at a time, consciously and unconsciously.

C. Obstacles to problem solving 3021. Confirmation bias looking only for answers that confirm your expectationsEX: The U.S. government “had a tendency to accept information which supported (their presumptions)…more readily than information which contradicted” them in the run up to the 2003 invasion of Iraq.

2. Fixation inability to look at a problem from a different perspectiveEx: matchstick problem on p. 303

5. Mental set type of fixation; works on previous solutions that were successful4. Functional fixedness thinking of things for their usual functionsex.: inability to see paperclip as a hook

D. Making Decisions and Forming Judgments 303Based on research by Amos Tversky and Daniel Kahneman

1. Representative heuristics (stereotyping, see Unit 14)Judging something according to how it matches your prototype

Ex: you’re told someone is strong muscular and fastYou think of the person as (representing) some kind of athleteThey could just be a fit professor

2. Availability heuristicsSeeing the likelihood of events based on how vivid your memory is of them3. OverconfidenceOverestimating the accuracy of your judgments

The belief perseverance phenomenon, 307You keep your belief even though the original source is wrong or discreditedRobert Rosenthal found this in 1972: teachers’ expectations influenced whether students performed well in school. Teachers who didn’t think a student was capable wouldn’t change their minds even if the student presented evidence they were very capable. This is the Pygmalion effect.

Fear Factors: Do we fear the right things? 308a. what we can’t control “perceived control”b. if it is immediatec. the availability heuristic: what we can more easily remember affects usd. our ancestral history has prepared us to fear certain thingse. if the event or object is vivid

The effects of framing 311The way something is set up affects your thinkingEx: more positive response to Beef is 75% lean (rather than 25% fat)Those who understand how it works use it to “nudge” us in a direction of their choosing (Cass Sunstein’s argument and research)

Belief biasThe tendency for your beliefs to distort your logical reasoning ability

Intuition, 310a. guarantees a quick responseb. is often adaptive

Artificial intelligencea. Computerized systems that mimic human thinking

b. Computers are faster than humans on many tasks; but humans can parallel process; computers use serial processingEx: robots that “sense” their environment; ex: chess programs that beat humansNeural networksComputer circuitry that resembles the human brain neuron connections Can mimic the exhibitory and inhibitory messages of human brain functioning

II. Language 313Noam Chomsky: language is the human essence.

A. Language structureWhat are the structural components of a language? B. gestured, spoken and written words that communicate meaning

1. PhonemeThe smallest unit of soundEx: fish has three phonemes: f, i, sh2. MorphemeThe smallest meaningful unitEx: the pronoun I, the article “a” (most are comb. of two or more phonemes)3. GrammarRules of the language allowing us to understand ita. Semantics

Rules to derive meaning from morphemes, words and sentencesEx: adding –ed to laugh means it happened in the pastb. SyntaxHow to combine words into meaningful sentencesEx: adjectives usually occur before nouns: white house---not house white

B. Stages of language development 412We learn an average of 3500 words per year after age 1.

When do we learn language?What are the milestones in language development?1. Babbling: spontaneous uttering sounds

a. 3-4 months after birthb. not imitation of parents c. sounds unlike the parents’ language are uttered

Around 4 mos. baby begins to be language receptive--- can comprehend language; later will bemoving toward language productive to be able to produce language

2. One word stagea. Around age 1b. Have learned that sound carries meaningc. First word contains one syllable; ex: “ma”, “da” d. As child moves to multiple syllables, one word can mean a whole sentence

3. Two word stagea. Prior to age 2b. two word sentences resembling Telegraphic speechc. ex: I hungry, me play, want candyd. no three word stage; Children jump to longer phrases

C. Explaining language Development 316 How do we learn language?

1st view: B. F. Skinner, learned by operant conditioning (behaviorist)b. association: sights with soundsc. imitation: modelingd. reinforcement

2nd view: Noam Chomsky, inborn, universal grammar (linguist)a. ability to speak language is largely inbornb. we have a language acquisition capacity (language acquisition device)c. surface structure is all the rules of language (syntax, etc.)d. Deep structure is the meaning of language

e. Universal grammar: all languages have the same building blocks; no matter what he language we basically speak mostly in nouns, naturally like birds learning to fly.

f. Chomsky says Skinner’s view is that language is learned like filling a vessel with water; instead language learning is rather like helping a flower to grow

3. Research: biology prepares us to use words and grammar; experience during the first few years of life is critical to mastering a language; thus nature starts us out, nurture shapes our growth.

a. after age 7 child loses ability to master any other languageb. Critical period: childhood, for mastering certain aspects of languagec. Sensitive period: an ideal period for learning something, but if you don’t

learn it then you can learn it later, less easily.

Overgeneralization in language: Myers gives examples where kids overextend rules; or, they might call all four legged creatures “doggies” or all flying machines “airplanes”.

Linguistic competence: understanding or producing sentences you have never before heard.

III. Thinking and Language 319What is the relationship between language and thinking?

A. Whorf’s Linguistic determinism (Linguistic relativity theory):1. Language determines how we think

2. most evident in those speaking two languagesEx: someone who speaks Chinese & EnglishThey feel differently depending on the language they use*English emphasizes personal emotions*Chinese emphasizes interpersonal emotions

Bilingual advantage those learning two languages are better at ignoring irrelevant information. Identified by Wallace Lambert (p. 321)

Denotation: the dictionary definition of a wordConnotation: the emotional or contextual meaning of a word

B. Thinking in Images 321Thinking can occur without languageEx: artists using mental imageryEx: Einstein used visual imageryImagining an activity triggers some of the same areas of the brain involved in actually performing that activity.

Works in academics: outcome simulation, visually your grade, was less successful than process simulation, imagining studying to get the grade.

Appendix D-1 to D-6 Do animals think or use language?

Apes and monkeys can form concepts.Chimps are natural too users.Chimps have numerical ability.Alex the parrot also uses numbers.Researchers found 39 chimp customs and can transmit cultural patterns.

Animals also use insight.Apes, dolphins and elephants demonstrate self-awareness (similar to the Rouge Test used by babies)

Do Animals Exhibit Language? D-3A. Animals can communicate using sound or behavior

ex: bees dictating the location of nectar with an elaborate danceex: the Gardner’s taught a chimp, Washoe, to communicate using sign language (she knows 181 signs)

1. Koko, a gorilla trained by Penny Patterson, can sign far more signs than Washoe and has a pet cat.

2. “McGyver” gorillas appear to use tools3. Other gorillas demonstrate creativity by painting and

naming their art4. Rico, a border collie, can fetch 200 items by name.

B. Skeptics of animal language D-41. Their vocab is very limited2. only learned with great difficulty3. they often mix up the few symbols they can use4. they only do it to get a reward; Herbert Terrace found this

when training Nim Chimsky (1979)5. their syntax is below a 3 yr. Old6. they are just aping their trainers

Roger Fouts found that Washoe could train her adopted son to sign (1992). Human language appears to have evolved from gestured communication. We talk and think with our hands; this allows for sign language. Some people even gesture while communicating over the phone!Sue Savage-Rumbaugh found that chimps can comprehend syntax.Whether or not animals use language depends on how you define the term.
