3ThinkingThinking, or cognition, refers to a process that involves knowing, understanding, remembering, and communicating.OBJECTIVE 1| Define cognition.
4COGNITIONThe early settlers on the Isle of Begile were a rather conservative group who established the Island’s bylaws. One of the first laws passed was that all the men were to be clean-shaven, and furthermore, no man was allowed to shave himself. To make matters even more trying, the bylaws stipulated that all men must be shaved by a licensed barber.
5COGNITIONFor whatever reason, the Isle only issued one barber’s license, and that was to an elder who was nearing eighty years of age. Strangely enough, everything seemed to work until a landed immigrant lawyer arrived on the scene and asked the overlooked question, “If no man is allowed to shave himself, who then shaves the barber?” How did the Begilers avoid this paradox?
6COGNITIONCOMPLETE 9-18a and 9-18b. Pay attention to your thought processes as you solve the problems.
7Cognitive Psychologists Thinking involves a number of mental activities, which are listed below. Cognitive psychologists study these in great detail.ConceptsProblem solvingDecision makingJudgment formation
8ConceptThe 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.Concepts provide us with a lot of information without much cognitive effort.OBJECTIVE 2| Describe the roles of categories, hierarchies, definitions, and prototypes in concept formation.

13Development 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.J. Messerschmidt/ The Picture CubeDaniel J. Cox/ Getty ImagesTriangle (definition)Bird (mental image)
14CategoriesOnce we place an item in a category, our memory shifts toward the category prototype. This affects recognition time. We are slow to recognize information that doesn’t fit our prototype (leads to prejudice)Courtesy of Oliver CorneilleA computer generated face that was 70 percentCaucasian led people to classify it as Caucasian.
15PROBLEM SOLVING COMPONENTS Understanding the problem or diagnosisDevising a plan to solve itExecuting the planEvaluating the results
16STRATEGIES FOR PROBLEM SOLVING Decomposition: divide into smaller, more manageable partsWork backwardFind analogiesIncubation (forgetting incorrect ideas that may have been blocking path to correct solution)
17There are two ways to solve problems: Problem SolvingThere are two ways to solve problems:Algorithms: Methodical, logical rules or procedures that guarantee solving a particular problem.OBJECTIVE 3| Compare algorithms and heuristics as problem-solving strategies, and explain how insight differs from both of them.
18S P L O Y O C H Y G 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 GIf we were to unscramble these letters to form a wordusing an algorithmic approach, we would face907,208 possibilities.
19HeuristicsHeuristics 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

21HEURISTICS We use heuristics to reduce our options Then we use trial and error
22InsightInsight involves a sudden novel realization of a solution to a problem. Humans and animals have insight. Kohler’s experiment with Sultan to the right:Grande using boxes toobtain food
23InsightBrain imaging (fMRI) and EEG (electrical signature) studies suggest that when an insight strikes (the “Aha” experience), it activates the right temporal cortex (Jung-Beeman, 2004). The time between not knowing the solution and realizing it is 0.3 seconds. Provides a sense of satisfaction.From Mark Jung-Beekman, NorthwesternUniversity and John Kounios, Drexel University
24DECISION- GROUP AImagine that you serve on the jury of an only-child sole custody case following a relatively messy divorce. The facts of the case are complicated by ambiguous economic, social, and emotional considerations, and you decide to base your decision entirely on the following few observations. To which parent would you award sole custody of the child?
25DECISIONParent A, who has an average income, average health, average working hours, a reasonable rapport with the child, and a relatively stable social life, or Parent B, who has an above-average income, health problems, lots of work-related travel, a very close relationship with the child, an extremely active social life.
26DECISION – GROUP BImagine that you serve on the jury of an only-child sole custody case following a relatively messy divorce. The facts of the case are complicated by ambiguous economic, social, and emotional considerations, and you decide to base your decision entirely on the following few observations. To which parent would you deny custody?
27Obstacles in Solving Problems Confirmation Bias: A tendency to search for information that confirms a personal bias.2 – 4 – 6OBJECTIVE 4| Contrast confirmation bias and fixation, and explain how they can interfere with effective problem solving.Rule: Any ascending series of numbers. 1 – 2 – 3 would comply. Ss (?) had difficulty figuring out the rule due to a confirmation bias (Wason, 1960).
28CAUSES OF CONFIRMATION BIAS COGNITIVE CONCEITCOGNITIVE LAZINESSWe seek evidence verifying our ideas more eagerly than evidence refuting our ideasExamples: WMD/Iraq; Therapists
37Functional FixednessA 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.

39Functional FixednessUse 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 isfunctional fixedness. Another example?
41IGNORING NEGATIVE EVIDENCE Don’t forget: negative means removal or absence not badThe absence of symptoms can provide important evidence for or against a hypothesis, but symptoms or events that do not occur are less likely to be noticed and observedExample: ?
42MULTIPLE HYPOTHESESMay be due to limited capacity of short-term memory.If time: multi-attribute exercise
43Using and Misusing Heuristics Two kinds of heuristics, representative heuristics and availability heuristics, have been identified by cognitive psychologists. KNOW THEIR NAMES!OBJECTIVE 5| Contrast the representative and availability heuristics, and explain how they can cause us to underestimate or ignore important information.Courtesy of Greymeyer Award, Universityof Louisville and the Tversky familyCourtesy of Greymeyer Award, Universityof Louisville and Daniel KahnemanAmos TverskyDaniel Kahneman
44Representativeness Heuristic Judging the likelihood of things or objects in terms of how well they seem to represent, or match, a particular prototype.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?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.
45Availability Heuristic Why does our availability heuristic lead us astray?Whatever increases the ease of retrieving information increases its perceived availability.Example: mono (explain)How is retrieval facilitated?How recently we have heard about the event.How distinct it is.How correct it is.
46ANCHORING HEURISTIC (BASE RATE FALLACY) Definition: estimate the probability of an event, not by starting from scratch but by adjusting an earlier estimateEx: When you begin AP Psychology, you assume ……….
47GAMBLER’S FALLACYDefinition: Belief that events in a random process will correct themselvesExample:
48DECISION MAKING PITFALL ACTIVITY Write a dialogue to illustrate some flaws in thinking. Possible scenarios might include a criminal, a gambler, or a movie star discussing events from their lives with another individual (Reporter? Attorney? Etc). Include at least three of the following pitfalls. Do not identify them by name.Anchoring heuristicRepresentativeness heuristicGambler’s fallacyAvailability heuristic
49DECISION MAKING PITFALLS ACTIVITY Team up with another group.Read your dialogue to this group.The second group should analyze your dialogue and determine how it illustrates the decision making pitfalls, and label each.Reverse roles.
50Making Decision & Forming Judgments Each day we make hundreds of judgments and decisions based on our intuition, seldom using systematic reasoning.Affects our social judgments.A lot of important decisions involve judgments of risk.
51OverconfidenceIntuitive heuristics, confirmation of beliefs, and the inclination to explain failures increase our overconfidence. Overconfidence is a tendency to overestimate the accuracy of our beliefs and judgments.OBJECTIVE 6| Describe the drawbacks and advantages of overconfidence in decision making.At a stock market, both the seller and the buyer may be confident about their decisions on a stock.
52OVERCONFIDENCE Can have devastating consequences (political example?) However, overconfidence does have adaptive value:HappierEasier to make tough decisionsSeem more credible
53OVERCONDIFENCEResearchers have found that people with high self-confidence are more susceptible to flattery than those with low self-confidence.In a sentence or two, why do you think this is true?
54The 9/11 attacks led to a decline in air travel due to fear. Exaggerated FearThe opposite of having overconfidence is having an exaggerated fear about what may happen. Such fears may be unfounded.The 9/11 attacks led to a decline in air travel due to fear.AP/ Wide World Photos
55FEAR FACTOR FOUR INFLUENCES ON OUR INTUITIONS ABOUT RISK. WE FEAR: What our ancestral history has prepared us to fearWhat we cannot controlWhat is immediateWhat is most readily available in memory*
56FEAR FACTORVivid events distort our comprehension of risks and probably outcomesWe fear too much those things that have killed people dramatically, in bunches, and recentlyWe fear too little threats that claim lives undramatically, one by one, and in the distant past/future
57FEAR FACTORCotton swabs injure more people than razor blades or shavers!Chairs are more than 13 times as likely to cause injuries as chain saws.411,689 Americans in one year experienced injuries related to beds, mattresses, and pillows.
58DECISIONYou’ve decided to see a Broadway play and have bought a $100 ticket. As you enter the theater, you realize you’ve lost your ticket. You can’t remember the seat number so you can’t prove to the management that you bought a ticket. Would you spend $100 for a new ticket?
59DECISIONYou’ve reserved a seat for a Broadway play for which the ticket price is $100. As you enter the theater to buy your ticket, you discover you’ve lost $100 from your pocket. Would you still buy the ticket, assuming you have enough cash left to do so?
60DECISIONMost people will buy a ticket after losing cash but not after losing the ticket. Why?Tversky suggests people set up a mental account. In problem (a) that account has already been charged $100; to replace the ticket would double the account. In the second problem the $100 loss is charged to some other account, such as next month’s lunch money or next year’s vacation.
61Framing DecisionsDecisions and judgments may be significantly affected depending upon how an issue is framed.Example: What is the best way to market ground beef — as 25% fat or 75% lean?OBJECTIVE 7| Describe how others can use framing to elicit from us the answers they want.
62FRAMINGGive an example from the “Blink” article to illustrate framing and thin slicing (inferring the motivations and intentions of others with subtle, fleeting cues)Give an example from the “Blink” article to illustrate the importance of facial expressions.
63Blink Why is Gladwell’s book titled Blink? According to Gladwell, what caused the shooting of Armadou Diallo?What was the relationship between autism and the Diallo shooting?What are some recommendations for dealing with stressful situation according to the information presented in the article?Summarize in a few sentences the conclusions of Gladwell regarding decision making.
64Belief BiasThe tendency of one’s preexisting beliefs to distort logical reasoning by making invalid conclusions. We more easily see the illogic of conclusions that run counter to our beliefs than of those that agree with our beliefs.OBJECTIVE 8| Explain how our preexisting beliefs can distort our logic.
65Often fuels social conflict. Belief PerseveranceBelief perseverance is the tendency to cling to our beliefs in the face of contrary evidence.Often fuels social conflict.If you see that a country is hostile, you are likely to interpret their ambiguous actions as a sign of hostility (Jervis, 1985).OBJECTIVE 9| Describe the remedy for belief perseverance phenomenon.
66Perils & Powers of Intuition Intuition may be perilous if unchecked, but may also be extremely efficient and adaptive.OBJECTIVE 10| Describe the smart thinker’s reaction to using intuition.
78GENDER AND COMMUNICATION Read the handout: Gender and the Communication ProcessWhat are the differences between men and women in their communication patterns? Do you agree? Have things changed since this article was written?What evidence supports the statement that gender differences in social power affect cross-sex conversations?
79Language StructurePhonemes: The smallest distinct sound unit in a spoken language. For example:bat, has three phonemes b · a · tchat, has three phonemes ch · a · tOBJECTIVE 11| Describe the basic structural units of language.
80Unforgettable = un · for · get · table Language StructureMorpheme: The smallest unit that carries a meaning. It may be a word or part of a word. For example:Milk = milkPumpkin = pump . kinUnforgettable = un · for · get · table
81Structuring Language Phonemes Morphemes Words Phrase Sentence Basic sounds (about 40) … ea, sh.MorphemesSmallest meaningful units (100,000) … un, for.WordsMeaningful units (290,500) … meat, pumpkin.PhraseComposed of two or more words (326,000) … meat eater.SentenceComposed of many words (infinite) … She opened the jewelry box.
82GrammarGrammar is the system of rules in a language that enable us to communicate with and understand others.GrammarSemanticsSyntax
83SemanticsSemantics is the set of rules by which we derive meaning from morphemes, words, and sentences. For example:Semantic rule tells us that adding –ed to the word laugh means that it happened in the past.
84SyntaxSyntax consists of the rules for combining words into grammatically sensible sentences. For example:In English, syntactical rule says that adjectives come before nouns; white house. In Spanish, it is reversed; casa blanca.

86When do we learn language? Babbling Stage: Beginning at 4 months, the infant spontaneously utters various sounds, like ah-goo. Babbling is not imitation of adult speech.OBJECTIVE 12| Trace the course of language acquisition from the babbling stage through two-word stage.
87When 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.
88When do we learn language? Two-Word Stage: Before the 2nd year a child starts to speak in two-word sentences. This form of speech is called telegraphic speech because the child speaks like a telegram: “Go car,” means I would like to go for a ride in the car.
89When 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.
91Explaining Language Development Operant Learning: Skinner (1957, 1985) believed that language development may be explained on the basis of learning principles such as association, imitation, and reinforcement.OBJECTIVE 13| Discuss Skinner’s and Chomsky’s contributions to the nature-nurture debate over how children acquire language, and explain why statistical learning and critical periods are important concepts in children’s language learning.
92Explaining Language Development Inborn Universal Grammar: Chomsky (1959, 1987) opposed Skinner’s ideas and suggested that the rate of language acquisition is so fast that it cannot be explained through learning principles, and thus most of it is inborn.Overgeneralizing (-ed added, etc) is support for this theoryLAD (language acquisition device)Surface vs deep structure
93Explaining Language Development 3. Statistical Learning and Critical Periods: Well before our first birthday, our brains are discerning word breaks by statistically analyzing which syllables in hap-py-ba-by go together. These statistical analyses are learned during critical periods of child development.

100DoublespeakDefiniton: language designed to alter our perception of reality and to corrupt our thinkingSometimes humorous and relatively harmless, it can also be used to avoid responsibility, to make the bad seem good, the negative positive, the unpleasant attractive. Explanation?
101Language Influences Thinking Linguistic Determinism: Whorf (1956) suggested that language determines the way we think. For example, he noted that the Hopi people do not have the past tense for verbs. Therefore, the Hopi cannot think readily about the past.OBJECTIVE 14| Summarize Whorf’s linguistic determinism hypothesis, and comment on its standing in contemporary psychology.
102Language Influences Thinking When a language provides words for objects or events, we can think about these objects more clearly and remember them. It is easier to think about two colors with two different names (A) than colors with the same name (B) (Özgen, 2004).
103Word PowerIncreasing word power pays its dividends. It pays for speakers and deaf individuals who learn sign language. Helps explain the bilingual advantage: learning to inhibit one language while using their other language, are also better able to inhibit their attention to irrelevant information.
104Linguistic Determinism Questioned Although people from Papua New Guinea do not use our words for colors and shapes, they still perceive them as we do (Rosch, 1974).
105Thinking in ImagesTo a large extent thinking is language-based. When alone, we may talk to ourselves. However, we also think in images.We don’t think in words,OBJECTIVE 15| Discuss the value of thinking in images.1. When we open the hot water tap.2. When we are riding our bicycle.

119Can animals infer mental states in themselves and others? To some extent. Chimps and orangutans (and dolphins) used mirrors to inspect themselves when a researcher put paint spots on their faces or bodies.
120Do Animals Exhibit Language? There is no doubt that animals communicate.Vervet monkeys, whales and even honey bees communicate with members of their species and other species.OBJECTIVE 17| Outline the arguments for and against the idea that animals and humans share the capacity for language.Copyright Baus/ KreslowskiRico (collie) has a200-word vocabulary
121The Case of ApesChimps do not have a vocal apparatus for human-like speech (Hayes & Hayes,1951). Therefore, Gardner and Gardner (1969) used American Sign Language (ASL) to train Washoe, a chimp, who learned 182 signs by the age of 32.
122Gestured Communication Animals, like humans, exhibit communication through gestures. It is possible that vocal speech developed from gestures during the course of evolution.
123When asked, this chimpanzee uses Sign LanguageAmerican Sign Language (ASL) is instrumental in teaching chimpanzees a form of communication.Paul Fusco/ Magnum PhotosWhen asked, this chimpanzee usesa sign to say it is a baby.
124Computer Assisted Language Others have shown that bonobo pygmy chimpanzees can develop even greater vocabularies and perhaps semantic nuances in learning a language (Savage-Rumbaugh, 1991). Kanzi and Panbanish developed vocabulary for hundreds of words and phrases.Copyright of Great Ape Trust of Iowa
125CriticismApes acquire their limited vocabularies with a great deal of difficulty, unlike children who develop vocabularies at amazing rates.Chimpanzees can make signs to receive a reward, just as a pigeon who pecks at the key receives a reward. However, pigeons have not learned a language.Chimpanzees use signs meaningfully but lack syntax.Presented with ambiguous information, people tend to see what they want to see (Clever Hans Phenomenon).
127ConclusionsIf we say that animals can use meaningful sequences of signs to communicate a capability for language, our understanding would be naive… Steven Pinker (1995) concludes, “chimps do not develop language.”
