    Thinking & Intelligence

    (Modules 24, 25, 26)

    Cognition - MentalActivities IncludingThose Such as Thinking,Reasoning, and ProblemSolving.

    2

    Cognitive Psychology or

    Science - A Subdiscipline

    Within Psychology ThatStudy These Related Issues.

    (Rapidly Growing Area

    within Psychology)

    3

    Concepts- Mental

    Categories for Objects

    or Events that areSimilar to One Another

    in Certain Respects.

    e.g., Furniture or

    Birdness

    4

    Concepts are Often

    Described as Being

    Artificial Concepts or

    Natural Concepts.

    5

    Artificial Concepts -

    Concepts that Can be

    Clearly Defined by a Set of

    Rules or Properties.

    e.g., Triangles, Robins,

    Oxygen.

    6

    Natural Concepts -

    Concepts that Do Not have

    Clear-Cut Boundaries

    (often defined by

    Prototypes).

    e.g., Clothing, Furniture,

    Art

    7

    Prototype- The Best or

    Clearest Example of Various

    Objects or Stimuli in thePhysical World.

    e.g., What do You Think of

    When I Ask, Name a Type

    of Bird? or A Type of

    Vehicle?8

    Schemas - Cognitive

    Frameworks That

    Represent Our KnowledgeAbout Aspects of the World.

    e.g.., Going to Class or

    Going to a Movie

    9

    Positive vs. Negative

    Instances: A Stimulus that

    is an Example of a Concept

    under Study is a Positive

    Instance, if it is Not, then It

    is a Negative Instance.

    e.g., A Raccoon is a Mam-

    mal but a Robin is Not.

    10

    Generally, It is Easier to

    Detect A Positive Instance

    vs. a Negative One.

    11

    Paragraph Test - What is

    So Unusual About The

    Following Paragraph?

    If you know the Solution,

    Do not Give it Away

    Immediately.12

    How fast can you spot

    what is unusual about this

    paragraph? It looks soordinary that you might not

    think anything was wrong

    with it at all and, in fact,

    nothing is. But it is atypical.

    Why?

    13

    Study its various parts,

    think about its curious

    wording, and you may hit

    upon a solution. But you

    must do it without aid; my

    plan is not to allow any

    scandalous misconduct in

    this psychological study.14

    No doubt, if you work hard

    on this possibly frustrating

    task, its abnormality will

    dawn upon you. You cannot

    know until you try. But it is

    commonly a hard nut to

    crack. So, good luck!

    15

    I trust a solution is

    conspicuous now. Was it

    dramatic and fair, although

    odd? Authors hint: I cannot

    add my autograph to this

    communication and

    maintain its basic harmony.

    Authors Name is Steuben.

    16

    Problem Solving - Efforts to

    Develop or Choose Among

    Various Responses in Orderto Attain a Desired Goal.

    e.g., Matchstick Problem

    17

    Task: How Would You Arrange 6

    Matches to Form 4 Equilateral

    Triangles? (Solution -->)18

  • 8/13/2019 Gen Psy Exam 3 Slides All

    3/14

    19

    Task: How Can you Intersect all 9 Dots with A

    Series of 4 Straight Lines (or Less) Without

    Lifting up Your Pen? 20

    Can It Be

    Done with

    3 Lines ??

    21

    Here you Must Imagine that the Lines continue

    for Some distance until they Intersect, as all

    such non-parallel lines must.

    22

    Candle Problem: Task Determine Way to

    Use Candle(s) as a Stable Light Source

    w/ Objects Available.

    23

    Two-String Problem: Task Connect the

    Strings Together w/ Objects Available.

    24

    Algorithms- Procedures

    or Rules That Guarantees a

    Solution to a Given

    Problem.

    e.g., A Computer Program

    or Following a Recipe.

    25

    Heuristics - Mental Rules

    of Thumb That Usually

    Enable Us to Make aDecision or Solve a Problem.

    However, They Can be

    Inexact.

    26

    While Heuristics Often Lead

    Us to Make a CorrectDecision, They Dont

    Always ...

    27

    Which of the Following Pairs ofConditions Causes More Deaths

    in the U.S. Yearly? (A or B?)

    1. All Accidents or Strokes?2. All Cancers or Heart Disease?

    3. Botulism or Small Pox Vaccinations?

    4. Electrocution or Asthma?

    5. Homicide or Diabetes?

    6. Motor Veh Accidents or Cancer of Dig. System?

    7. Tornado or Excessive Exposure to Cold?

    8. Lightning or Appendicitis?

    9. Motor Vehicle/Train Collision or Tuberculosis?

    10. Drownings or Leukemia?

    4/14

    28

    Would You Believe B In AllCases? Why May This Be?

    1. All Accidents or Strokes?

    2. All Cancers or Heart Disease?3. Botulism or Small Pox Vaccinations?

    4. Electrocution or Asthma?

    5. Homicide or Diabetes?

    6. Motor Veh Accidents or Cancer of Dig. System?

    7. Tornado or Excessive Exposure to Cold?

    8. Lightning or Appendicitis?

    9. Motor Vehicle/Train Collision or Tuberculosis?

    10. Drowinings or Leukemia?29

    Availability Heuristic -

    Rule of Thumb Where the

    Probability of an Event isJudged on the Basis of How

    Readily It Comes to Mind.

    30

    Another Heuristic Can Be

    Demonstrated from the

    Following Example (NoNeed to Copy Example).

    31

    Linda is 31, Single,

    Outspoken, and Very

    Bright. She Majored in

    Philosophy in College, Was

    Concerned with Social

    Issues, and Participated in

    Antinuclear Demon-

    strations.32

    Which Statement is More

    Likely?

    A. Linda is a Bank Teller

    or

    B. Linda is a Bank Teller

    and Active in the Feminist

    Movement.33

    While Many Choose B,

    A is More Likely to Be

    Correct.

    Why?

    34

    Because of the Fact that Any

    Two Uncertain Events

    Occurring Together is

    Always Less Likely than the

    Odds of Either Happening

    Alone.

    35

    Therefore, If You Chose

    B, You Likely Used the

    RepresentativenessHeuristic - Where the

    Probability of an Event is

    Judged on the Basis of How

    Well They Seem to Match a

    Particular Prototype.36

    While Heuristics Often

    Lead Us to Make AGood or Correct

    Decision, In Certain

    Cases They Can Lead us

    Astray.

    37

    Other Tendencies May Also

    Hamper Our Ability to

    Solve A Problem.

    e.g., Functional Fixedness-

    The Tendency to Think of

    Using Objects Only as They

    Have Been Used in the Past.38

    Given: Box of Matches, 12

    Tacks, and a Candle.

    Task: Attach the Candle to a

    Wall to be Used as a Light

    Source.

    39

    Solution: Using A Box of

    Matches as a Holder For the

    Candle.

    Some Companies Now

    Stress Creativity - New or

    Novel Ways of Viewing or

    Solving Problems.

    41

    Marvels of the Human

    Mind -

    (1) It Has Been Estimated

    that the Circuitry in the

    Human Brain Has 60 Times

    the Informational Capacity

    of the Entire U.S. Telephone

    System.42

    (2) Each of Us KnowsNearly 50,000 Facts AboutEvery Topic On Which WeAre Reasonably Knowledge-able. e.g., Our PersonalIdiosyncrasies, Our OwnBody, or Words andGrammar of Native

    Language.

    43

    (3) In the Course of A

    Lifetime, The Average

    Person Can Accumulate 500

    Times More Information as

    is Contained in the

    Encyclopedia Britannica.

    44

    It is Easy To Take For

    Granted The EnormouslyComplex Mental Acts We

    Routinely Perform Every

    Day.

    45

    e.g., Whats a 7-letter Word,

    that Ends in y that Meansa group of Interacting

    Individuals Living

    In the same region with the

    Same Culture?

    46

    A: Society.

    Pretty Easy? Or Was It? ButHow Did You Manage to

    Find the Word So Quickly

    Among the

    50,000 - 75,000 Words in

    Your Working Vocabulary? 47

    Q: What is George

    Washingtons Phone

    Number?

    You Quickly Recognize the

    Question as Absurd, But

    Why? What Would a

    Computer Do? 48

    Q: In the Place You Lived

    Two Residences Ago, Did

    Your Front Door Open atthe Left Side or the Right

    Side?

    How and Why Do You

    Recall This Information So

    Easily and Efficiently?

    49

    Intelligence - No UniversallyAccepted Definition. OneUsed by Wechsler is: TheAggregate or GlobalCapacity of the IndividualTo Act Purposefully, toThink Rationally, and toDeal Effectively

    With the Environment.50

    The History of the Use of

    Intelligence Tests is Long and

    Controversial.

    Nearly 4000 Years Ago in

    China Persons Were Given

    Written Exams for Civil

    Service Positions.51

    The First Modern

    Intelligence Tests Were

    Designed by Alfred

    Binet and Theodore Simon

    in France. Their Task Was

    to Identify Children Who

    Would Not Benefit from

    Formal Schooling.

    52

    David Weschsler Devised A

    Series of Tests to Measure

    Intelligence.eg., For Adults - Weschler

    Adult Intelligence Scale

    (WAIS). For Children -

    Weschler Intelligence Scale

    for Children (WISC-R).53

    Controversy With

    Intelligence Tests.

    One Common Complaint isthe Issue of Whether

    Intelligence Tests

    Are Culture - Fair or

    Unbiased Against Different

    Races or Groups.54

    The Use of Virtually Any

    Language Poses a Problem...

    One Attempt to Devise a

    Culture-Fair Test is to Not

    Use Words. How?

    55

    The Raven Standard

    Progressive Matrices Test

    (1948) is One Attempt.

    Not All Agree Even this Test

    is Culture Fair.

    56 57

    58

    I.Q. - Intelligence Quotient

    IQ =Mental Age (MA)

    Chronological Age (CA)

    100 is Average, So those above

    are Considered Bright while

    Below are Deficient.

    X 100

    59

    Today, Many Believe

    Intelligence is Best Viewed as

    Being of Different Types.

    eg., Daniel Goleman - Wrote

    Emotional Intelligence

    (1995) Belief that Adapting

    Well to Emotions Is Critical.60

    For Fun: Savant

    Syndrome - A Condition in

    Which People with Serious

    Mental Handicaps, Either

    from Retardation or Mental

    Illness, Have Spectacular

    Islands of Ability or

    Brilliance. [Movie:Rainman]

    61

    Darold Terfferts

    Extr aordinary People:

    Understanding Idiot

    Savants (1989) is an

    Excellent Source of

    Examples...

    62

    George and His Identical

    Twin Brother Charles can

    Give you the Day of the

    Week for any Date over a

    span of 80,000 Years. Also,

    They can Describe the

    Weather on Any Day of

    Their Adult Life... 63

    However, They Cannot Add

    or Count to 30, and they

    Cannot Determine Change

    from a $10 bill for a $6

    Purchase.

    Upon hearing Tchaikovskys

    Piano Concerto No 1 for the

    First Time in his Teen Years,Leslie Played it Back

    Flawlessly and without

    Hesitation. He Can Do the

    Same with any other Piece of

    Music, No Matter How Long 65

    Or Complex. Unfortunately,

    Leslie is Severley Mentally

    Handicapped, Blind, and hehas Cerebral Palsy.

    66

    Motivation & Emotion

    (Modules 28, 29, 30)

    Motivation - An InferredInternal Process thatActivates, Guides, andMaintains Behavior OverTime. Many Theories HaveBeen Proposed to Explain It.

    67

    InstinctTheory - Theory ofMotivation that SuggestsBehavior Stems from InnateUrges or Tendencies.

    Instinct - Patterns ofBehavior Assumed to beUniversal in a Species.

    e.g., Bill Pecking By Gulls.68 69

    Drive Theory - Theory of

    Motivation that Suggests

    Behavior is Pushed by

    Biological Needs.

    e.g.., Thirst or Hunger.

    70

    Homeostasis- A State ofPhysiological Balance within

    the Body.

    Evidence Suggests that Weare More Motivated WhenHomeostasis is Shifted (e.g.,Water or Food Depletion -->Seek These Items). 71

    Arousal Theory - Theory of

    Motivation that Suggests We

    Seek an Optimal Level ofArousal or Activation.

    Many Studies Show Our

    Performance is Best Under

    ModerateLevels of Arousal.72

    Expectancy Theory -Theory of Motivation thatSuggests Behavior isElicited by Expectations ofDesirable Outcomes(Cognitive Theory).e.g., Why are You TakingThis Class?

    74

    Self-Actualization

    Physiological Needs

    Safety Needs

    75

    Specific Behaviors: Eating

    and Drinking.

    Much Research Has BeenDone to Study The Process

    of Food and Water Intake.

    Evidence Suggests They

    Are Complex Processes.

    76

    (1998) - SurveyAmericansdon't drink enough Water -While 2 out of 3 Americansresponding to a surveyknow they should drinkeight 8 oz. servings of waterdaily, 1 in 2 admits notgetting enough ...

    77

    The survey also showedpeople may be "drinkingthemselves to dehydration"by consuming too manyalternative water-robbingbeverages.

    78

    As We Age, Our ThirstMechanims Dont SignalUs to Drink as Readily asYoung Therefore, OlderPersons Need to GuardAgainst Dehydration.

    79

    Brain Regions Shown to Be

    Significant in Eating and

    Drinking.

    Two Areas of the

    Hypothalamus Have Been

    Found Critical for Food

    Intake in Rats.80

    (1) Lateral Hypothalamus

    (LH)- May be Called a

    Start-Eating Center,

    Since Stimulation Leads to

    Eating and Destruction of

    Area Leads Animals Not to

    Eat.81

    Ventromedial Hypothalamus(VMH) - May be Called a

    Stop-Eating Center, SinceStimulation Leads to theStopping of Ongoing Eatingand Destruction Leads toOvereating and ObeseAnimals.

    Eating Disorders:

    Anorexia Nervosa - An

    Eating Disorder in WhichIndividuals Starve

    Themselves and Often Lose a

    Dangerous Amount of

    Weight. e.g., Karen

    CarpenterSinger from 70s

    85 86

    Anorexia - Persons often

    have an Intense Fear of

    Becoming Obese.

    No Single Cause of Anorexia

    is Agreed Upon, Some

    Include:

    87

    1. Problem with

    Hypothalamus.

    2. Fears of Sexuality.

    3. Struggle for Control w/

    Parents.

    88

    4. Cultural Preoccupation

    with Being Thin; Many

    Believe They Are Too Fat.

    What is Our Societys

    Message?

    Research F indings:

    Leora Pinhas from the U. ofToronto Presented 118Female University Studentswith Two Series of Images(1 containing FemaleFashion Models, the OtherNo Human Figures)...

  • 8/13/2019 Gen Psy Exam 3 Slides All

    11/14

    91

    Both Before and After StudyWomen Were Given

    Questionnaires to DetermineTheir Mood State,Satisfaction with TheirBodies, and Risk ofDeveloping an EatingDisorder. (Any Predictions?)

    92

    Results: They Were MoreDepressed and Angry

    Following Exposure to theFashion Models. Also, Thosewith the Highest Propensitytoward Eating DisordersResponded with GreaterAnger to the Female Slides.

    93

    Findings Suggest thatThese Images have a

    Detrimental Effect onWomen and May Play aRole in Episodes of BingeEating in Response toNegative Mood States.

    94

    Less Idealized Media

    Portrayals of Women May

    Become an Important

    Public Health and

    Preventive Health Issue.

    Do You Think It Will?

    95

    Research Suggests That

    Relatives of People with

    Eating Disorders Have

    Higher Risks for

    Developing Similar

    Disorders (1998).

    96

    Treatment for Anorexia is

    Often Difficult; in Part

    Due to Belief Nothing is

    Wrong.

    97

    Bulimia- An Eating

    Disorder in which Periods

    of Binge Eating Alternate

    with Periods of Self-

    Induced Purging (via

    Vomiting or use of

    Laxatives).98

    Characteristics of Bulimics

    1. Most Females in Late

    Teens or 20s.

    2. Often of Higher

    Socioeconomic Class.

    99

    Characteristics of

    Bulimics

    3. Body Weight Often

    Fluctuates Within or

    Above Normal Weight

    (often Hides Condition).

    Problems of Bulimics -

    1. Erosion of Tooth

    Enamel.

    2. Dehydration or

    Electrolyte Imbalance.

    102

    Problems of Bulimics -

    1. Erosion of Tooth

    Enamel.2. Dehydration or

    Electrolyte Imbalance.

    3. Depression and/or

    Mood Swings.

    103

    Problems of Bulimics -

    1. Erosion of Tooth Enamel.

    2. Dehydration or

    Electrolyte Imbalance.

    3. Depression and/or Mood

    Swings.

    4. Time is Limited for Other

    Activities.104

    Cognitive Approaches to

    Motivation:

    Intrinsic Motivation - The

    Desire to Perform

    Activities Because They

    are Self-Rewarding.

    e.g., Hobbies (No

    Payment).105

    Extrinsic Motivation -

    Pursuit of Activities Because

    of External Rewards or

    Punishment.

    e.g., Payment, Praise,

    Threats.

    106

    Q: Are Intrinsic and

    Extrinsic Motivation

    Related? How?

    107

    Some Research Suggests

    that Behaviors Once

    Engaged in For Intrinsic

    Reward Can Be Reduced or

    Undermined by the Addition

    of ExtrinsicRewards.

    108

    e.g., Harry Harlow - Story

    of Rhesus Monkeys and

    Wooden Puzzles.

  • 8/13/2019 Gen Psy Exam 3 Slides All

    13/14

    109

    Other Studies Suggest theSame Outcome Occurs withHumans.

    e.g., Deci - Found College-Students Reduced TheirLevel of Puzzle-SolvingFollowing Rewards. But...

    110

    However, a Reduction in

    Behavior is Not Always the

    Case. Recent EvidenceSuggests that if the External

    Rewards are Viewed as

    Recognition, not Bribes,

    Intrinsic Motivation May be

    Enhanced.111

    Achievement Motivation -

    The Desire to Accomplish

    Difficult Tasks and MeetStandards of Excellence.

    Clearly, People Differ In

    This Behavior. How Can it

    Be Measured?

    112

    Projective Tests - VariousTests that Aim to HavePersons Project or RevealTheir Beliefs or Desires(Motives).

    113

    e.g., the ThematicApperception Test (TAT) -Test Consisting of a Series ofAmbiguous Pictures WhichPersons are Asked About.

    114

    115

    Rorschach Inkblot Test -Another Projective Test,

    That Consists of a Series ofAmbiguous PatternsFormed from Blotted InkDeposits.First Formulated by a SwissPsychiatrist (Rorschach).

    Answers, Those with a High

    Need to Achieve Frequently

    Including Success, Getting

    Ahead, and Competition.

    118

    Today, the Validity (or

    Accuracy) of the

    Rorschach test is inQuestion, Yet some

    Clinicians Believe in its

    Use.

    119

    Emotions - Reactions That

    Typically are Composed of 3

    Major Components:(1) Physiological Changes

    (2) Subjective Cognitive

    States

    (3) Expressive

    Behaviors.120

    e.g., the Polygraph (LieDetector) MachineSimultaneously Records A

    Number of PhysiologicalSystems Such as Heart Rate,Blood Pressure,Respiration Rate,and Skin Conduc-tance Levels (GSR).

    121

    Polygraphs are Used in

    Certain Cases for Trials and

    For Some Job Screening,

    But Interpretation of Tests

    Must Be Done

    Cautiously.

    Why?

    122

    All of These Measures areCommon Body Processes;There is No Measure of OurActual Thought Processes.Changes SuggestDisturbancesin Thought, But They Could BeDue to Other ThanGuilt or Lies. WhatAbout Fear?
