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-

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

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

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.

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?

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?

The Raven Standard
Progressive Matrices Test
(1948) is One Attempt.
Not All Agree Even this Test
is Culture Fair.

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

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.
[Some Psychologists have
Suggested it is GoodTo
Forget Many Things]

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.

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
Needs to Belong
Esteem Needs
MaslowsHierarchy of Needs (1970)
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.

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.
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).
116
Example Rorschach Pattern
What Do You See ?117
Through Scoring Such
Answers, Those with a High
Need to Achieve Frequently
Create Stories with Themes
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?
