Building Blocks of Thought
LEARNING OBJECTIVE: Describe the three basic building blocks of thought and give an example of each. Explain how phonemes, morphemes, and grammar (syntax and semantics) work together to form a language.
The three most
important building
blocks of thought:
Building Blocks of Thought
4
Building Blocks of Thought“When you think of a close friend, you may have in mind complex statements
about her, such as “I’d like to talk to her soon”…You may also have an image
of her – probably her face, but perhaps the sound of her voice as well. Or you
may think of your friend by using various concepts or categories such as
woman, kind, strong…When we think, we make use of all of these things –
language, images, and concepts – often simultaneously.”
– Page 217 (Morris & Maisto)
Flexible system of
communication that uses
sounds, rules, gestures,
or symbols to convey
information
a n g u a g e
LANGUAGE
Language
Basic sounds that make up any language
Smallest meaningful
units of speech
Rules that determine how sounds and words can be
combined and used to communicate
Rules for combining words to form meaningful phrases, sentences
Surface and underlying meanings of words and phrases
5
Direction of Movement in Speech Production and Comprehension
Images
• Mental representations of sensory experiences
– Allow us to think
about things in
nonverbal ways
Concepts
• Mental categories for
classifying objects,
people, or experiences
– Prototype (or model):
mental model containing
the most typical features
of a concept
6
Language, Thought, and Culture
Language, Thought, and CultureLEARNING OBJECTIVE: Summarize the evidence for the idea that people in different cultures
perceive and think about the world in different ways. Explain what is meant by “linguistic
determinism” and summarize the evidence for and against it.
• Linguistic relativity
hypothesis: Whorf’s idea
that patterns of thinking are
determined by the language
one speaks
• Linguistic determinism:
More general belief that
thought and experience are
determined by language
• Softened Whorf hypothesis
• Language, thought, culture
are intertwined
• Experience shapes
language, language affects
subsequent experience
Benjamin Whorf Critics
Is Language Male Dominated?
Research supports the
idea that words such as
he or she influence our
perception of males and
females.
The words he and man are
often used to refer to all
people.
7
Nonhuman Language and Thought
• All animals communicate
in some way.
• Only humans can communicate
verbally and in complex ways.
• Research: Some animals
have humanlike
cognitive capacities.
Nonhuman Thought and Language
LEARNING OBJECTIVE: Summarize research evidence that supports the statement that
“nonhuman animals have some humanlike cognitive capacities.” Explain the following
statement: “All animals communicate, but only humans use language to communicate.”
Problem Solving
8
Three Aspects of the Problem-Solving Process
Interpreting Problems
Problem representation:
First step in problem-solving;
involves interpreting or
defining the problem
LEARNING OBJECTIVE: Explain why problem representation is an important first step
in solving problems. In your explanation include divergent and convergent thinking,
verbal, mathematical and visual representation, and problem categorization.
DIVERGENT
Thinking that meets the
criteria of originality,
inventiveness, and
flexibility
CONVERGENT
Thinking directed
toward one
correct
solution to
a problem
Divergent & Convergent Thinking
9
Problem-Solving Strategies
Works best when choices
are limited; wastes
time when there
are many options
to test
LEARNING OBJECTIVE: Distinguish between trial and error, information retrieval, algorithms, and
heuristics as ways of solving problems. Give an example of hill-climbing, subgoals, means-end
analysis, and working backward. Explain how “mental sets” can help or hinder problem solving.

Problem-Solving Strategies
Rules of thumb that help in simplifying and solving problems, but do not guarantee a correct solution
• Hill climbing: Moves you closer to the final
goal with each step
• Subgoals: Use intermediate, more
manageable goals to make it easier to reach
the final goal
• Means-end analysis: Aims to reduce the
discrepancy between the current situation
and the desired goal at a number of
intermediate points
• Working backward: Works backward from the
desired goal to the given conditions
Implementing Strategies and Evaluating Progress
Heuristics
Informationretrieval
Algorithm
Trial and Error
Obstacles to Solving Problems
• Level of motivation, or
emotional arousal
• Mental set: The tendency
to perceive and to
approach problems in
certain ways
– Functional fixedness:
Perceive only a limited
number of uses for an object
– Brainstorming:
Helps to minimize mental
sets
Applying Psychology
1. Eliminate poor choices.
2. Visualize a solution.
3. Develop expertise.
4. Think flexibly.
11
Decision Making
Decision Making
LEARNING OBJECTIVE: Explain how decision making differs from problem solving.
Describe the process of compensatory decision making and the use of decision-making
heuristics. Explain how framing can affect decisions, and how hindsight bias and
counterfactual thinking affect that way we view our decisions after the fact.
Decision making:
Type of problem solving in
which we already know all
of the possible solutions or
choices
Compensatory Decision Making
Compensatory model:
Rational decision-making model in which choices are
systematically evaluated on various criteria
12
Representativeness:
A new situation is
judged on the basis
of its resemblance
to a stereotypical
model
Decision-Making Heuristics
Availability:
A judgment or
decision is based
on information that
is most easily
retrieved from
memory
Confirmation bias:
The tendency to
look for evidence in
support of a belief
and to ignore
evidence that would
disprove it
Framing
• Perspective from which we
interpret information before
making a decision
• Way information is
presented can influence a
final decision
Explaining Our Decisions
Hindsight bias:
The tendency to see
outcomes as inevitable
and predictable after we
know the outcome
Counterfactual thinking:
Thinking about alternative
realities and things that
never happened
13
Multitasking
Multitasking
• With digital technology
(i.e., iPods, Internet)
multitasking is a way of
life.
• According to research,
multitasking isn’t always
efficient.
• Multitasking may actually
interfere with the
successful completion of
task.
Intelligence and Mental Abilities
14
General term
referring to the
ability or
abilities
involved in
learning and
adaptive
behavior
n t e l l i g en ce
• Intelligence is
comprised of seven
distinct, independent
mental abilities.
• Individuals can excel
in certain areas but
not in others.
• Intelligence is a
singular, general
quality about a person.
• People who are bright
in one area are usually
bright in other areas as
well.
Charles Spearman L.L. Thurstone
LEARNING OBJECTIVE: Compare and contrast the theories of intelligence put forth by
Spearman, Thurstone, Sternberg, Gardner, and Goleman.
Theories of Intelligence
Sternberg’s Triarchic Theory
ANALYTICAL: Involves mental
processes emphasized by
most theories of intelligence
CREATIVE: Involves
adapting to new tasks
and situations, to gain
insight
PRACTICAL: Involves
finding solutions to
practical and
personal problems
15
Gardner’s Multiple Intelligences
1. Linguistic
2. Musical
3. Logical
mathematical
4. Spatial
5. Bodily-kinesthetic
6. Interpersonal
7. Intrapersonal
8. Naturalistic
Emotional Intelligence
Five traits that contribute to
emotional intelligence:
1. Knowing one’s own
emotions.
2. Managing one’s
emotions.
3. Using emotions to
motivate oneself.
4. Recognizing the
emotions of other
people.
5. Managing relationships.

LEARNING OBJECTIVE: Describe the similarities and differences between the Stanford-Binet
Intelligence Scale and the Wechsler Intelligence Scales, and explain how they differ from group
tests, performance tests, and culture-fair tests of intelligence. Explain what is meant by test
“reliability” and “validity” and how psychologists determine whether an intelligence test is reliable
or valid.

Validity: Ability of a test to
measure what is has been
designed to measure
• Content validity: Having an adequate
sample of questions measuring the
skills or knowledge the test is
supposed to measure
• Criterion-related validity: Validity
measured by a comparison of the test
score and independent measures of
what the test is designed to measure
What Makes A Good Test?
Reliability: ability of a test
to produce consistent and
stable scores
What Makes A Good Test?
Split-half reliability:
Determines test reliability by
dividing the test into two parts
and checking the agreement
of scores on both parts
Correlation coefficients:
Statistical measures of the
degree of association between
two variables, used to measure
reliability

Criticisms of IQ Tests
IQ tests are controversial because psychologists
disagree on the definition of intelligence.
Critics argue that the tests assess a very limited set of
mental skills and that some tests may be unfairly biased
against minority groups.
Poor performance in school may be the result of, rather
than caused by, low test scores.
Psychologists tend to agree on the validity of IQ tests to
predict academic grades and obtaining high-status
occupations such as M.D.s and lawyers.
LEARNING OBJECTIVE: Summarize the criticisms of intelligence tests and the
relationship between IQ test scores and job success.
Heredity, Environment, and Intelligence
Heredity, Environment, and Intelligence
Is intelligence inherited,
or is it the product of environment?
LEARNING OBJECTIVE: Summarize the evidence that both heredity and environment
(including intervention programs) affect intelligence.
EnvironmentHeredity
Approximately 50% of the differences in
intelligence are due to genetics, and
50% are due to differences in environment.
Intelli gence
20
Heredity
• Help scientists understand
the influence of heredity
• Identical twins raised
together – most similar IQs
• Identical twins raised by
different families – still have
very similar IQ scores

Twin Studies
Environment
Many environmental influences on intelligence:
• Socioeconomic status
• Prenatal nutrition
• Level of environmental stimulation
Intervention programs:
• Milwaukee Project, Head Start
• Seem to have a significant impact on cognition between the ages of 3 and 5.
Influences
The IQ Debate: A Useful Model
• IQ scores have increased in the
population as a whole.
• Possible explanations:
– The population is better at test-taking.
– There have been improvements in
nutrition and health care.
– The modern world is increasingly
complex.
LEARNING OBJECTIVE: What is the “Flynn Effect”? What are some of the explanations
that have been offered for it?
Flynn Effect
21
RELATIONSHIP BETWEEN HEREDITY AND ENVIRONMENT
“Suppose that you grow one group of randomly assigned plants in enriched soil,
and another group in poor soil. The enriched group will grow to be taller and
stronger…the difference between the two groups in this case is due entirely to
differences in their environment. Within each group of plants, however,
differences among individual plants are likely to be primarily due to genetics,
because all plants in the same group share essentially the same environment.
Thus, the height and strength of any single plant reflects both heredity and
environment.”
– Page 245 (Morris & Maisto)
Mental Abilities and Human Diversity: Gender and Culture
LEARNING OBJECTIVE: Summarize the
evidence regarding gender differences and
cultural differences in mental abilities.
• Research: Males and females
don’t differ significantly in most
cognitive abilities.
• When observed, differences are:
– Relatively small
– Concentrated in very
specific skills
Gender
• Achievement gap between
American and Asian students
• American students lagging
behind
• Differences reflect cultural
attitudes toward importance of
ability and effort
Mental Abilities and Human Diversity: Gender and Culture
Culture
22
Mental Retardation
• Low IQ and the inability to
function independently
must both be present
• Causes often unknown,
although approx. 25% of
cases can be traced to
biological causes
• Variety of intervention
programs
LEARNING OBJECTIVE: Explain what is required for a diagnosis of mental
retardation and summarize what is known about its causes. Describe what is
meant by “inclusion” and whether it has been shown to be beneficial.
Extremes of Intelligence
Extremes of Intelligence
LEARNING OBJECTIVE: Explain what
is meant by saying a person is “gifted.”
Explain the pros and cons of special
programs for gifted children.
Giftedness
• Special abilities usually
exhibited in only a few areas
• Causes often unknown
• Pros and cons to enrichment
programs:
– Intellectually fulfilling
– Accompanied by social
concerns
Creativity
23
rea t iv i ty
The
ability to
produce novel
and socially
valued ideas
or objects
• Early research found no
correlation between creativity
and intelligence, but these early
studies focused only on bright
individuals.
• Threshold theory: Creativity
and intelligence are linked up
to a certain level of IQ, but then
the relationship disappears.
– Support for this theory
has been mixed.
Intelligence and Creativity
LEARNING OBJECTIVE: Describe the relationship between creativity
and intelligence,and the ways in which creativity has been measured.

Lecture Activities
Tower of Hanoi
Time to solve another problem. The object of the game is to move
ALL of the disks onto a different pole. The rules are these:
1) You can only move one disk at a time.
2) A bigger disk can't go on a smaller disk.
See how quickly you can solve the tower in seven moves.
Click the next slide to see the solution.
25
• Did you use an algorithm or a heuristic
to solve that problem?
• What types of day-to-day problems might require
algorithmic solutions?
• What types of daily problems could be handled more
heuristically?
• What do your conclusions suggest about the nature
of problem solving?
A Mental Set
Try this one. On your paper,
draw nine dots just like you
see up here. Then, see if you
can draw four straight lines
so that they pass through
ALL nine dots without lifting
your pencil from the page
AND without touching any
dot more than once?
(Click button to reveal solution)
26
Did you solve the problem? Did you experience any
“insight”? If not, what was it that kept you from doing
so? Was it thinking about the group of circles as a
square with solid boundaries? How can you break free
from mental sets to “step outside of the box” when you
need to?
Breaking Through
Functional Fixedness
On the next slide you will
see various items on a desk
and be presented with a
problem to be solved. Let’s
see who is able to break
through their functional
fixedness.
Using only the items on top of the desk, how could you attach the candle to the wall ABOVE the desk, so that when the candle burns, it does NOT drip wax onto the desk?
27
Perhaps the most elegant
solution to this problem is to:
1. Empty the matches out
of the box.
2. Tack the empty box to the wall.
3. Place the candle in the box.
This solution requires one
to avoid fixating on the
normal function of the box
as that of holding matches.
Avoiding this trap allows
one to see more than one
use for the box (i.e., as a
candle holder).
See Gardner’s list of intelligences. Are there
any other types of intelligence Gardner’s list
might still be missing?
Intelligence Test Activity
The speed with which an
individual can verbally identify
simple concepts is a critical
measure of intelligence. In this
activity, you will be presented
with colored stimuli. Your task
will be to identify correct colors
as quickly as possible. We will
go through this as a group.
28
n
• Was this test a VALID
measure of
intelligence?
Why? Why not?
• Was this test a
RELIABLE measure of
intelligence? Why?
Why not?
29
Intelligence Testing
Could you create a test
that is free of cultural
bias? What sorts of
test items might you
incorporate? Math?
Picture completion?
Explain your
reasoning.
Creativity
Time to harness some of that
doodling creativity. On a sheet
of notebook paper, see how
many different pictures you
can draw, using this image
comprising two circles. Don’t
worry about drawing perfect
pictures. Just make sure
that the circle image is in each
of your pictures. Work quickly.
You will have 60 seconds.
Time is up! After such a task, a psychologist
studying creativity might be interested in
answers to the following types of questions:
1. How many pictures did you draw?
2. Were the pictures from different semantic
categories (e.g., fruits, sports, cars, etc.)?
3. Were your pictures unique? In other words, did
you draw pictures that others probably did not?
