THINKING & LANGUAGE Unit 7B THINKING Thinking, or cognition, refers to a process that involves knowing, understanding, remembering, and communicating. Cognitive Psychologists Study Concepts Problem Solving Decision Making Judgment Formation CONCEPTS Concepts – the mental grouping of similar objects, events, ideas, or people. For example… There are a variety of chair types, but their common features define them as a chair. We form some concepts with definitions. A triangle has three sides. We also form Prototypes – A robin is a prototypical bird, while penguin is not. CATEGORY HIERARCHIES We organize concepts into category hierarchies. PROBLEM SOLVING Problem Solving Strategies Trial & Error Algorithms Heuristics Insight TRIAL & ERROR We’re all used to this approach. Try, try, try again. For example… Will your joke make Teacher laugh? ALGORITHMS Exhaust all possibilities before arriving at a solution. Computers use algorithms. Very time consuming. SPLOYOCHYG If we unscramble these letters to form a word using an algorithmic approach, we would face 907,200 possibilities. HEURISTICS Heuristics – thinking strategies that allow us to make judgments and solve problems efficiently. Less time consuming than algorithms. More error prone than algorithms. For example… Words with two Y’s probably end in a Y. SPLOYOCHYG SPLOYOCHGY REPRESENTATIVENESS HEURISTIC Judging the likelihood of things or objects in terms of how well they seem to represent, or match, a particular prototype. If you see a slim, short, man who wears glasses and a beard, and likes poetry, what do you think his profession might be. An ivy league professor or a truck driver? AVAILABILITY HEURISTIC Whatever increases the ease of retrieving information increases its perceived availability. How is retrieval facilitated? How recent have we heard about the event? How distinct is it? How correct is it? INSIGHT Insight involves a sudden novel realization of a solution to a problem. Humans and animals have insight. INSIGHT Brain imaging and EEG studies suggest that when insight strikes, it activates the right temporal cortex. Your “Aha” Moment OBSTACLES IN SOLVING PROBLEMS Confirmation Bias – a tendency to search for information that confirms personal bias. For Example… If you are good at soccer, and are watching another high school soccer game, you will probably search for information that suggests the other team/player is not as good as you. FIXATION Fixation – an inability to see a problem from a fresh perspective. This impedes problem solving. The Matchstick Problem How would you arrange six Matches to form four Equilateral triangles? THE MATCHSTICK PROBLEM - SOLUTION THE CANDLE MOUNTING PROBLEM Using these materials, how would you mount the candle on a bulletin board? CANDLE MOUNTING PROBLEM - SOLUTION MAKING DECISIONS & FORMING JUDGMENTS Each day we make hundreds of judgments and decisions based on our intuition, seldom using systematic reasoning. For example, what is the fastest way out of this classroom? OVERCONFIDENCE A tendency to overestimate the accuracy of our beliefs and judgments. For Example… In the stock market, both the seller and the buyer may be overconfident about their decisions on a stock. Have you ever got a “bad” deal when buying a car, or are you confident that you got a good deal? Faulty Decision Making Confirmation Bias – A tendency to seek out information that confirms our previously held beliefs Belief Perseverance – The tendency to hold onto our belief even in the face of evidence against our belief…our beliefs distort our logic Overconfidence – The tendency to count on our own estimates and beliefs too much Framing Decisions – The way we are presented the information needed for making the decision can impact what we decide Ex: coat for $100 or same coat for $150 at 33% off EXAGGERATED FEAR The opposite of having overconfidence is having an exaggerated fear about what might happen. For example… The 9/11 attacks led to a decline in air travel due to fear. THE EFFECTS OF FRAMING Decisions and judgments may be significantly affected depending upon how an issue is framed. Example… What is the best way to market ground beef? 25% Fat 75% Lean THE BELIEF PERSEVERANCE PHENOMENON Belief perseverance is the tendency to cling to our beliefs in the face of contrary evidence. If you see that a country is hostile, you are likely to interpret their ambiguous actions as a sign of hostility (Jervis, 1985). For example… Can you believe that Iraq is now starting form an independent government? LANGUAGE Language – our spoken, written, or gestured work, is the way we communicate meaning to ourselves and others. Language transmits culture. LANGUAGE DEVELOPMENT Children learn their native languages much before learning to add 2+2. We learn on average (after age 1) 3,500 words a year, amassing 60,000 words by the time we graduate form high school. WHEN DO WE LEARN LANGUAGE? Babbling Stage Beginning at 4 months. The infant spontaneously utters various sounds, like ah-goo. Not an imitation of adult speech. 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, means, look at the dog out there. Two-Word Stage – before the 2nd year, a child starts to speak in two-word sentences. Also called telegraphic speech because the child speaks like a telegram. Go car, means, I would like to go for a ride in a car. WHEN DO WE LEARN LANGUAGE? Longer Phrases – after telegraphic speech, children begin uttering longer phrases with syntactical sense, and by early elementary school they are employing humor. For example… Mommy get ball. EXPLAINING LANGUAGE DEVELOPMENT Operant Learning – Skinner believed that language development may be explained on the basis of learning principles such as association, imitation, and reinforcement. Inborn Universal Grammar – Chomsky 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. EXPLAINING LANGUAGE DEVELOPMENT Childhood is a critical period for fully developing certain aspects of language. Children never exposed to any langue (spoken or written) by about age 7, gradually lose their ability to master any language. GENES, BRAIN, & LANGUAGE Genes design the mechanisms for language, and experiences modifies the brain. CRITICAL PERIOD Learning new languages gets harder with age. THINKING & LANGUAGE Language and thinking intricately intertwine. Language and the Brain w As a child grows, his/her language develops. Usually, understanding language occurs before the production of language. Wernicke’s Area understand speech Broca’s Area produce speech Parts of Language Phonemes: Smallest unit of sound that can be understood as part of a language (40 in English) - Ex: The m of mat, the b of boy, or the ch in church Morphemes: Smallest unit of sound that conveys a meaning in a language. Can be individual or combinations of phonemes - Ex: Unit consisting of a word, such as man - Ex: A word element, such as -ed in walked - Ex: Phoneme such as I ** cannot be divided into smaller meaningful parts** Grammar: Set of rules that enables us to use our language • Semantics – Refers to aspects of meaning assigned to language (Ex: adding “ed” means it happened in the past) • Syntax – The system of rules we use to string words together into proper sentences (Ex: adjectives come before nouns) Pic: Units of Language Kinds of Intelligence Gardner - Theory of Multiple Intelligences • He believed that intelligence could be broken down into seven categories: LANGUAGE INFLUENCES THINKING Linguistic Determinism – Whorf (1956) suggested that language determines the way we think. For example… He noted the Hopi people do not have the past tense for verbs. Therefore, the Hopi cannot think readily about the past. THINKING IN IMAGES To a large extent thinking is language based. When alone, we may talk to ourselves. However, we also think in images. For example… Turning on the hot water. How to ride your bike. ANIMAL THINKING & LANGUAGE Do animals have a language? Honeybees communicate by dancing. The dance moves clearly indicate the direction of the nectar. Do animals think? Some animals have shown the ability to… Concept formation Insight Problem solving Culture
