Thinking
       1. What is the Nature of Thought?

• -9/11- rational decision making?
• What does your mom look like?
  – Mental image
• In alphabet what letter comes after N?
  – L,M,N,O
• How much is 2+2
  – Did “4” -immediately pop into your mind?
• What is Julia Roberts’s phone number?
                  2.Thinking

• What is thinking?
  – Attending to information, using it or
  – Representing it mentally
  – Reasoning about it, and
  – Making judgments and decisions about it
  – E.g., Making sense of and change the world
          3. Mental Images & Concepts

• Mental images- a mental representation that has
  some of the physical characteristics of an object
• Concept- a symbolic representations of objects; a
  category, a class, that includes subtypes and/or
  individual items (musical Instrument, other?)
  – used to group objects, relations, events, abstractions
    or qualities that have common properties, & cannot be
    measured
• Hierarchies
  – Used to organize concepts
                  Concepts

• Prototypes
  – Good examples of a category of concept
     • Exemplars
  – Positive and Negative instances
     • Overextension
                          4. Concepts

• Prototypes
  – Good examples of a category of concept
•   Name the first member that comes to your mind:
•   A bird______
•   A hero______
•   A Color______
•   An animal______
•   A Motor Vehicle_______
• Exemplars
  – Positive and Negative instances
     • Overextension
    5. When a Person Has a Problem?

• When s/he does not have a direct means of
  attaining a particular goal

           What is Problem Solving?

• Using the thoughts and actions to move from
  the current state to the goal state, in other
  words achieving a desired goal that is not
  readily attainable, often by devising strategies
  to overcome obstacles
       6. Organization of Subgoals

• High school senior decides to become a doctor
• First, s/he needs to attain more immediate
  subgoal:
1). _______
2)._______
3).________
4).________
– Identifying important subgoals is not always
  easy
             7. Trial and Error

• An approach to problem solving in which one
solution after another is tried in no particular
order until the answer is found
• Used when we have little or no knowledge
relevant to the problem
– Students give examples…
                  8. Algorithms

• Specific procedure for solving a type of problem
   – Yield correct answers if the right formula is
     used. Any math formula is an example of Alg
• Systematic random search (similar to trial and
  error)
   – Each possible solution is tested according to a
     particular set of rules
                             9. Heuristic

• Shortcuts; mental rules of thumb used to solve a
  problem
• Working backwards: Water lilies double the area they cover every
  24hours. At the beginning of the summer there is one water lily on a pond. It
  takes 60days for the pond to become covered with lilies. On what day is the
  pond half covered?

• Means-end analysis (subgroups)
  – Evaluate and reduce difference between the
    current situation and goal
• Analogies
  – Refer to a previous problem to solve a new
    problem
Logical reasoning and observation can be used
  to solve the problem: Play Video Elevator
          The Elevator Riddle Solution




                    PLAY
                    VIDEO
    10. Factors that Affect Problem Solving

• Expertise
   – Experts use parallel processing; novices use
     serial processing:
   – how long it will take you to unscramble this
     word: DNSUO
• Mental Sets
   – Tendency to use an approach that was
     previously successful with similar problem
• Insight
   – Sudden perception permitting the solution
    11. Factors that Affect Problem Solving

• Incubation
   – Stand back from a problem for a while; solution
     may come in a flash of insight
• Functional Fixedness
   – Tendency to think of an object in terms of its
     familiar function
       12. Heuristics in Decision Making
      (not covered in class, but will be included in the Quiz)


• Representativeness heuristic
  – Make judgments about events according to the
    population of events that they appear to
    represent
• Availability heuristic
  – Estimate of probability is based on examples of
    relevant events
       13. Heuristics in Decision Making
      (not covered in class, but will be included in the Quiz)


• Anchoring and adjustment heuristic
  – First estimate serves as an anchor
  – With new information we make adjustments but
    remain in the proximity of the first estimate
    14. Factors that Affect Decision Making
      (not covered in class, but will be included in the Quiz)

• Framing effect
   – Context in which information is presented
     affects decision making
• Overconfidence
   – Unaware of flimsiness of assumptions
   – Work to bring about results that fit our
     judgments
   – Forget information counter to our judgment
   – Self-fulfilling prophecies
15. Class Discussion on The Paradox of Choice

• Do you believe the more options you have the
  better?
• Do you find that too much choice can be
  frustrating?
• Satisficers- “good enough”
• Maximizers- “the best possible choice”
• “Paradox of Choice” might be responsible for cultural shift in
  the average age when people are settling into jobs and marriage??
• Responsible for depression in modern
  countries?
Language,
Lecture 13
       1. Communication by Nonhumans

• What capability most reliably sets humans
  apart from all other species?
• African Grey Parrots (Discuss Video)
  – Did Alex speak English? What is the difference
    between Alex’s usage of language and human usage?
• Apes (Washoe, Sarah, Lana, Nim & Kanzi)
  – Genetically show some ability to use language
  – Use of symbols to communicate
                   2. Apes

• Allen & Beatrix Gardner (1969)- Washoe used
  sign language beginning 1y.o. -160 signs
• David Premack (1983) –Sarah mastered notion
  of similarity and difference, half and whole
• Yerkes Primate Research Center (80s)-Lana
  computer controlled language training “Give
  apple which is orange)
• Kanzi-1300 utterances, 200 geometric symbols
• However, Herbert Terrace (1981)-Nim responded
  according to CC not rules of the language
         3.Communication in Other Animals

•   Whales and dolphins- “in basket,” “under basket”
•   Dogs
•   Other
•   “My father was poor but honest” (quoted in Restak, 1988, p.202)
                   4. Language

• A means of Communicating of thoughts and
  feelings, using a system of socially shared but
  arbitrary symbols (sounds, signs, or written
  symbols) arranged according to rules of
  grammar.
                5. Structure of Language

• Psycholinguistics-how language is acquired, produced, and
  used…
• Phonemes-the smallest units of sound in a spoken language
• Morphemes- the smallest units of meaning
• Syntax- specifies the rules for arranging and combining words to
  form phrases and sentences
• Semantics- the meaning derived from morphemes, words, and
  sentences
• Pragmatics- characteristics of spoken language, such as
  intonation and gestures, that indicate social meaning of utterances.
           6. Properties of Language

• Infinite creativity
   – Capacity to create rather than imitate
     sentences
• Displacement
   – Capacity to communicate in another time or
     place
          7. Language and Cognition

• Language is not necessary for thinking
• Concepts can be understood without knowing the
  word for the concept (e.g. roundness)
           8. Language and Culture

• Linguistic-relativity hypothesis (Whorf (1956))
   – Language structures the way we perceive the
     world
• Criticism of linguistic-relativity hypothesis
   – Images and abstract logical propositions may
     be used as units of thought
   – Range of concepts represent priority of the
     language not cognitive limitation
                    9. Bilingualism

• In other countries the majority of citizens speak
  two or more language
• Advantages of being bilingual:
   – Metalinguistic skills, the capacity to think about lang.
   – Ability to learn about the other culture in depth
• Disadvantages:
   – Decreased efficiency memory tasks involving words
   – But develop compensatory strategies, though respond
     more slowly
• Lose accent – younger than 10 or 11 y. o.
                10. Language Development

• At the age 17- 80,000 words
• From 18 m to 5- 14,000 words, average 9wrds/day
•   2-3 m- cooing sounds when along
•   20 weeks- mixes various vowels & consonants w/cooing
•   6 m- Babbles; utters phonemes of all language
•   8 m- focuses on phonemes, rhythm, & intonation of native language
•   12m- say single words; mimics sounds; understand some words
•   18-20m – uses two word sentences; 50 wrds, overextension
•   24m- 270 wrds; acquires suffixes & function wrds in a fixed sequence
•   30m – uses telegraphic speech
•   36m – begins acquisition of grammar rules; overregulation
          11. Language Development

• Prelinguistic vocalizations
   – Crying, cooing, babbling
      • All children babble the same sounds (even
        deaf children)
   – By 9 – 10 months foreign sounds are dropped
• First word is spoken about 1 year
           12. Development of Grammar

• Holophrase (2nd year)
  – Single words that express complex meanings
  – “Cookie” means “this is cookie” “I want cookie” “where is cookie?”
• Telegraphic speech (30mos), understanding syntax
   – Two-word sentences
   – Grammatically correct
   – Sequence of emergence of various two-word
     sentences is universal
          13. Development of Grammar

• Overextension /underextension (18-20m)
  – Application of a word, on the basis of some feature, to
    a broader rage of objects than is appropriate (“Daddy”)
• Overregulation (36m)
  – Application of regular grammatical rules to
    irregular verbs and nouns
• Between 7- to 9-years
  – Children realize words can have more than one
    meaning
      14. Nature and Nurture in Language
                 Development

• Learning Theory
   – Imitation and reinforcement,
   – Social cognitive perspective
      • Parent serve as models
  – What is wrong w/these perspectives?
• Nativist Approach
  – Innate factors cause children to attend to and perceive language
    in certain ways
  – neurologically prewired
  – Do not need instructions or reinforcement, only presence of
    language
       15. Nativist Approach to Language
                   Development

• Language acquisition device (LAD)- Chomsky
   – Represents the inborn tendency
   – Prepares nervous system to learn grammar
      • Universal grammar
• Psycholinguistic theory
   – Language acquisition involves interaction of
     environmental influences and inborn tendency
     to acquire language
  Interactionist perspective similar to Psycholinguistic theory.
  Reading to a child is very important for the language development!!!
                  Banishing Bilingualism
•   Preparation: Ask a student in your class who is bilingual to
    demonstrate their ability.



•   For this demonstration, have a student (more if there are more
    bilingual students) demonstrate their ability in the languages
    learned. Ask them to talk about when they learned the languages
    and how it has benefited them. Then present an article found in
    most libraries titled “Banishing Bilingualism” written by Katz and
    Kohl (2002). This article discusses efforts to banish bilingualism
    from education and how some states have moved forward with this.
    This topic can lead to a lively debate over bilingualism or English
    only.
   Intelligence
   Lecture 14th
What is Intelligence?
                   1. Intelligence

• Example, Marilyn Mach and Dr. Jarvik
• Did poorly in school: Churchill, Einstein, etc.
• IQ? Academic Achievement?

Cognitive & Emotional Intelligence, Nature of
 Intelligence, and how it is measured. Where does
 intelligence come from? Gifted & Retarded
             2. What is Intelligence?

• American Association of Psychologists (APA)
  defined intelligence as an individual’s “ability to
  understand complex ideas,… to adapt effectively
  to environment, … to learn from experience, to
  engage in various forms of reasoning, and to
  overcome obstacles by taking thought”

• Provides the basis for academic achievements
               3. Theories of Intelligence

• Intelligence is made up of a number of mental
  abilities (factors)
• Spearman’s g factor
  – General intelligence
  – s factor represents specific abilities
• Thurstone’s specific factors
  – Primary mental abilities: verbal comprehension, numerical ability,
    visual and spatial abilities, perceptual speed, word fluency,
    memory & reasoning.

• Are those different ways of assessing g or distinct
  intelligences?
       4. Theory of Multiple Intelligences

• Howard Gardner (handout)
  – Number of different intelligences
• Critics
        5. Triarchic Theory of Intelligence

• Robert Sternberg
  – Analytical
     • Academic ability
  – Creative
     • Ability to cope with novel situations and
       generate multiple solutions to problems
  – Practical
     • “Street smarts”
  Some texts: componential, experiential, & naturalistic
        6. Triarchic Theory of Intelligence

• Robert Sternberg
  – Analytical
     • Academic ability
  – Creative
     • Ability to cope with novel situations and
       generate multiple solutions to problems
  – Practical
     • “Street smarts”
  Some texts: componential, experiential, & naturalistic
            7. Emotional Intelligence

• The ability to apply knowledge about emotions to
  everyday life, involves an awareness of and an
  ability to manage one’s own emotions, self-
  motivation, empathy, and the ability to handle
  relationships. (EQ)
• Intrapersonal and interpersonal skills (empathy)
• Self-insight and self-control (self-motivation)
• Allows for coping with stress, depression, and
  aggressive behavior
             8. Emotional Intelligence

• Managing emotions does not mean suppressing
  them; not does it mean giving free rein to
  everyday feeling.
• Goleman (1995)“A life without passion would be
  a dull wasteland of neutrality, cut off and isolated
  from the richness of life itself” (p.56)
• We manage our emotions by expressing them in
  an appropriate manner.
               9. Creativity and Intelligence

• Creativity-the ability to produce original, appropriate, & valuable
    ideas &/or solutions to problems
• Creative people
  – Do things that are novel and useful
  – Take risks
  – Defy limits
  – Appreciate art and music

•   Relationship between intelligence test scores and standard
    measures of creativity is only moderate.
    10. Divergent and Convergent Thinking

• Divergent thinking
  – Freely associate to elements of problem
  – Best used in measuring creativity
• Convergent thinking
  – Thought is limited to present facts
  – Best used in intelligence testing


• Interrelated
             11. Savant Syndrome
                  (Rein Man?)

• An unusual combination of genius and low
  performance in different areas
• Autistic individuals
• The puzzle of savant syndrome is slowly
  unraveled
        12. Measurement of Intelligence

• Franz Gall (1758-1828)- measuring skull
• Stanford-Binet Intelligence Scale (SBIS)
   – Binet-Simon - produced child’s mental age
   – SBIS adapted for intelligence quotient (IQ)
      • IQ reflects relationship between mental and
        actual age
      • (Mental Age / Chronological Age)x100=IQ
        13. Measurement of Intelligence

• Wechsler Scales (the latest WAIS-III)
• 16 and older (but has for kids as well)
• Deviation Score
   – Separate subscales
      • Verbal and performance tasks
   – Three IQ scores are obtained:
    1. Verbal IQ
    2. Performance IQ
    3. Full Scale IQ
14. Approximate Distribution of IQ Scores
   15. Differences in Intellectual Functioning

• Socioeconomic and Ethnic Differences
  – Consideration of social class
     • Lower-class U.S. children score 10 – 15 IQ
       points lower than middle- and upper-class
  – Consideration of ethnicity
     • Impact of social class
  – Asian Americans more likely to graduate high
    school and complete college
     16. Do Intelligence Tests Contain Cultural
                       Biases?

• Tests may measure familiarity with dominant
  middle-class culture:
•   Caesar is to salad as______ is to brandy.
       a. Churchill     b. Napoleon      c. Hitler   d. Lincoln

• Culture-free Intelligence Tests
  – Cattel’s Culture-Fair Intelligence Test
• European American children outperform African
  American children on “culture-free” test
17. Sample Items from Cattell’s Culture-Fair
              Intelligence Test
  18. Gender Differences in Intelligence Tests

• Intelligence tests do not show overall differences
  in cognitive ability
   – Girls superior to boys in verbal ability
   – Boys excel in visual-spatial ability
   – Boys tend to score higher on math tests
• Group scores represent greater variation within
  the group than between the groups
    Nature and Nurture in
        Intelligence


Do You Think of Intelligence as
   an Inherited or a learned
        Characteristic?
     19. Genetic Influences on Intelligence

• Francis Galton (1822-1911)- heredity
• Environmentalists- intelligence product of …..
• Kinship studies
   – IQ scores of identical twins (MZ) are more
     alike than for any other pairs
   – Moderate correlations between fraternal twins,
     siblings and parents and their children
   – Weak correlations between children and their
     foster parents and between cousins
     20. Genetic Influences on Intelligence

• Twin Studies
   – IQ scores of MZ twins reared together have
     higher correlation than MZ twins reared apart
      • Being reared together is related to IQ
        similarities
• Minnesota Center for Twin and Adoption
  Research (Bouchard (1997), - reported that
  various types of twin studies have consistently
  yielded heritability of .60 to .70 for intelligence
     21. Genetic Influences on Intelligence

• Adoption Studies
  – Stronger relationship between IQ scores of
    adopted children and their biological parents
    than between children and adoptive parents
          22. Heritability of Intelligence

• Heritability is between 40% and 60%
  – About half the difference between your IQ
    score and the IQ scores of other people can
    be explained by heredity

• Environment is also important
     • Being reared together is related to IQ
       similarities
23. Findings of Studies of the Relationship
      between IQ Scores and Heredity
24. The Complex Web of Factors That Affect
          Intellectual Functioning
