Review
Harry Harlow Experiment
The young monkeys for
the most part ignored
the wire mother, even if
she
had food.
They became strongly
attached to the cloth
mother, whether she
gave food or not.
The touching mattered,
not the feeding. Harlow
called this contact
comfort or tactile touch.
Attachment goes
beyond nourishment
Social desirability bias
A term
used in scientific research to
describe the tendency of respondents to
reply in a manner that will be viewed
favorably by others. This will generally
take the form of over reporting good
behavior or underreporting bad behavior.
Amygdala [ah-MIG-dah-la]
two almond-shaped neural clusters that are
components of the limbic system and are
linked to emotion
Damage may cause an inability to detect the
emotional significance of facial expressions,
especially expression of fear.
The Lobes of the Brain
The
cerebrum is two hemispheres
connected by a band of fibers called the
corpus callosum
Divided into lobes
Occipital- vision
Parietal- senses from all over the body
Temporal- hearing, memory, speaking
Frontal- creative thinking, planning
Homeostasis- Our body’s tendency to maintain a
balanced state to survive
Belief perseverance-- clinging to one’s initial
conceptions after the basis on which they were
formed has been discredited
Stereotype threat--fear that one's behavior will
confirm an existing stereotype of a group with
which one identifies
Permissive parenting– children are
allowed to do what they wish; no clear
rules are enforced
Dissociation--conscious awareness
becomes separated (dissociated) from
previous memories, thoughts, and feelings
• Dissociative disorder--a disorder in which a
person experiences alterations in memory,
identity, or consciousness
• Dissociative amnesia--the inability to recall
important personal events or information;
usually associated with stressful events
• Dissociative fugue--a dissociative disorder
in which a person suddenly and
unexpectedly travels away from home or
work and is unable to recall the past
• Dissociative identity disorder--a person
exhibits two or more personality states,
each with its own patterns of thinking and
behaving
Schachter’s Two-Factor
Theory of Emotion

“I’m afraid”
To experience
emotion one
Fear

Classical Conditioning
Unconditioned Stimulus (UCS)
stimulus that unconditionally--automatically and
naturally--triggers a response
Unconditioned Response (UCR)
unlearned, naturally occurring response to the
unconditioned stimulus
salivation when food is in the mouth
Conditioned Stimulus (CS)
originally irrelevant stimulus that, after association with
an unconditioned stimulus, comes to trigger a
conditioned response
Conditioned Response (CR)
learned response to a previously neutral conditioned
stimulus
Anxiety Disorders-Obsessive Compulsive Disorder-uncontrollable pattern of thoughts is
called obsession; repeatedly performing
irrational actions, which is called a
compulsion.
Post-traumatic stress disorder-- victims of
traumatic events experience the original
event in the form of dreams or flashbacks
Phobias– intense, irrational fear of
objects, places, or even people
Predictive validity: Predicts a known
association between the construct you’re
measuring and something else.
Construct Validity —The extent to which an
assessment corresponds to other variables, as predicted
by some rationale or theory
hypochondriasis, in which a person who is in
good health becomes preoccupied with
imaginary ailments.
Experimental Variables
• Operational definition-- defines the exact manner in which
a variable is measured-- a statement of procedures
(operations) used to define research variables
• To test a hypothesis, an experimenter defines the variables of the
hypothesis:
– Cause: Independent variable (IV) the one experimenters
change or alter so they can observe its effects
• Marijuana: Plain cigarette versus cigarette containing 5 mg of
THC (the active ingredient in marijuana)
– Effect: Dependent variable (DV) one that changes in relation to
the independent variable.
• Appetite: Grams of ice cream consumed in 1 hour
• The experimenter manipulates the IV and measures the DV to test
the hypothesis
diathesis-stress model
Theory that explains behavior as both a result of biological and genetic
factors ("nature"), and life experiences ("nurture").Diathesis is the
heriditary predispostion to a disorder (from the Greek
diathesis=arrangement, from dia=asunder+tithenai=to place).Stress is
the environmental load put on the organism.
This theory is often used to describe the pronunciation of mental
disorders, like schizophrenia, that are produced by the interaction of a
vulnerable hereditary predisposition, with precipitating events in the
environment. This theory was originally introduced as a means to explain
some of the underlying causes of schizophrenia (Zubin & Spring, 1977).
In the diathesis-stress model, a genetic vulnerability or predisposition
(diathesis) interacts with the environment and life events (stressors) to
trigger behaviours or psychological disorders. The greater the underlying
vulnerability, the less stress is needed to trigger the behaviour/disorder.
Conversely, where there is a smaller genetic contribution greater life stress
is required to produce the particular result. Even so, someone with a
diathesis towards a disorder does not necessarily mean they will ever
develop the disorder. Both the diathesis and the stress are required for
this to happen.
Negative Reinforcement-- Occurs when an
aversive stimulus is prevented or
eliminated following a behavior. Makes
behavior more likely to recur.
Debriefing- researcher explains the study
to participants after they are finished. It
can reduce problems associated with the
use of deception in research.
Cognitive Approach
This perspective studies the way humans store
and process information; eg: might assess locus
of control
Study the way a person thinks – is it negative,
irrational, faulty, distorted, self-defeating,
unrealistic
Treatment– rational-emotive therapy, Beck’s
cognitive therapy, changing ways of thinking
Behaviorism
People–
Skinner, Pavlov, Watson
Operant conditioning, classical
conditioning, observational learning
Reinforcement, CR, CS, shaping,
modeling
Treatments– systematic desensitization,
extinction, modeling, counter conditioning,
aversion therapy, biofeedback training,
stress inoculation
Psychoanalytical
Freud,
Jung, Adler,
Repression, suppression, unconscious
motives,
Freud: Stages (oral, anal, phallic, latency,
& genital): personality structure-- id, ego,
superego– dreams= wish fulfillment
Treatments– free association, dream
analysis, hypnosis, insight therapy,
interpretation of resistance/transference
Biological
Chemical
& endocrine imbalances, genetic
& hereditary, brain damage,
Drug treatments, exercise, nutrition
The Humanistic Approach
Key features (2):
•
People strive for ‘actualization’
• Rogers: the self-concept consists of a perceived self and an
ideal self. Psychological health is achieved when the two match
•
Maslow: people have a hierarchy of needs. The goal of
psychological growth is to meet the need to achieve selfactualisation
Fundamental Attribution Error
tendency for observers, when analyzing
another’s behavior, to underestimate the
impact of the situation and to
overestimate the impact of personal
disposition
Piaget’s Stages of Cognitive
Development
Typical Age
Range
Description
of Stage
Developmental
Phenomena
Birth to nearly 2 years
Sensorimotor
•Object permanence
•Stranger anxiety
Experiencing the world through
senses and actions (looking,
touching, mouthing)
About 2 to 6 years
Preoperational
Representing things
with words and images
but lacking logical reasoning
About 7 to 11 years
Concrete operational
Thinking logically about concrete
events; grasping concrete analogies
and performing arithmetical operations
About 12 through
adulthood
Formal operational
Abstract reasoning
•Pretend play
•Egocentrism
•Language development
•Conservation
•Mathematical
transformations
•Abstract logic
•Potential for
moral reasoning
Drive-Reduction Theory
the idea that a physiological need creates an aroused
tension state (a drive) that motivates an organism to
satisfy the need
Social Facilitation
improved performance of tasks in the presence of
others
occurs with simple or well-learned tasks but not with
tasks that are difficult or not yet mastered
Overjustification Effect
the effect of promising a reward for
doing what one already likes to do
the person may now see the reward,
rather than intrinsic interest, as the
motivation for performing the task
Personality disorders
• Dependent Personality disorder– lack self
confidence, cannot express difference of opinion
with others, lets others make decisions for them.
They have no true identity
• Narcissistic personality disorder– inflated
sense of their own importance and a deep need
for admiration. They believe that they’re
superior to others and have little regard for
other’s feelings. But behind this mask of ultraconfidence lies a fragile self-esteem, vulnerable
to the slightest criticism.
Brain Scans
CT (computed tomography) Scan
a series of x-ray photographs taken from different angles and combined
by computer into a composite representation of a slice through the
body; also called CAT scan
PET (positron emission tomography) Scan
a visual display of brain activity that detects where a radioactive form
of glucose goes while the brain performs a given task
MRI (magnetic resonance imaging)
a technique that uses magnetic fields and radio waves to produce
computer-generated images that distinguish among different types of
soft tissue; allows us to see structures within the brain
Electroencephalogram (EEG) -- an amplified recording of the waves of
electrical activity that sweep across the brain’s surface
these waves are measured by electrodes placed on the scalp
Measures of Variance
Provide an index of how spread out
scores of a distribution are.
Range= subtract the lowest score from
the highest score.
Standard Deviation is a measure of
distance. The larger the standard
deviation, the more spread out the
scores are.

Paul Ekman
• Facial expressions of emotion are not culturally
determined, but universal across human cultures
and thus biological in origin
• He developed the Facial Action Coding System
(FACS) to taxonomize every human facial
expression
• Display rules-- Socialization establishes when it
is appropriate to display a given facial expression
in a given society and when it is not, thus causing
individuals to actively modulate the display of
emotions and other states. Ekman and Friesen
coined the term display rules to describe such
socially engendered forces that alter facial
expression.
Hypothetical thinking-- involves the
imagination of possibilities and the
exploration of their consequences by a
process of mental simulation. In
development, it is acquired last.
Personality Inventory
a questionnaire (often with true-false or
agree-disagree items) on which people
respond to items designed to gauge a wide
range of feelings and behaviors
used to assess selected personality traits
Hallucinations
sensory experiences without sensory
stimulation
EX 2: Case Studies or Case Histories
• In depth studies of one or a few people
• Often used to investigate rare or unusual conditions
• EX: Studying multiple births (triplets or
quadruplets, only so many)
• Data is gathered using observation methods,
interviews, and psychological testing
• This is the primary type of research that Freud used
• Disadvantage = results may not generalize beyond
the people being studied or to other cultures
2. Correlational research
Determines the relationship or correlation between two characteristics, events, or behaviors
Important: Does not prove that one thing causes another, just proves there is a relationship
Almost any two things or behaviors can be tested and proven related in some way
Correlational Study may determine 3 things:
• 1. There is no relationship (very rare)
• 2. Positive relationship
• As one behavior increases, the other increases
*None of these things causes the other, but they are related
• 3. Negative relationship
• As one behavior increases, the other decreases
*Again just because you are in sports doesn’t mean you don’t do drugs, but there is a
relationship
Correlation Coefficient
• Measures relationships, ranges from –1 to 1
•
-1 is a strong negative correlation
•
+1 indicates a strong positive correlation
•
EX: -.86 (strong negative relationship)
•
EX: .01 (very little relationship)
•
EX: .94 (very strong positive relationship)
3. Experimental research methods
Goals is to find facts and causes of things,
Variables (properties or characteristics of some event, object or person that can take on different
values or amounts
• Experiments manipulate variables
–

•
•
•
Qualitative or Quantitative?
1. Qualitative variables (quality can be measured, but not with numbers)
2. Quantitative variables (can measure quantity with numbers or stats)
A. Discrete or Continuous?
Discrete variables (have possible scores of discrete points on a scale)
B.Continuous variables (have a continuous scale)
C. Independent Variable
Variable that is manipulated by an experimenter
Produces change in the experiment
Variable that you use to make predictions
D. Dependent Variable
Variable that you are trying to predict
Factor observed and measured for a change,
DV depends on changes in the independent variable
Usually a test or measurement taken at the end of the experiment
In most experiments, there are 2 Groups:
1. Experimental group (exposed to the IV, group that played the violent game)
2. Control group (not exposed to the IV, group that played the non violent game, used as a
comparison)
• Cross sectional research– studying groups
of people at various age levels; advantage–
takes less time.
• Longitudinal research– studying a group of
people intermittently at varying times
(every 5 years).
Pain
Gate-Control Theory
theory that the spinal cord contains a
neurological “gate” that blocks pain signals
or allows them to pass on to the brain
“gate” opened by the activity of pain signals
traveling up small nerve fibers
“gate” closed by activity in larger fibers or
by information coming from the brain
Social Relations
Mirror image perceptions– how we see
“them” they see “us”
Self-serving bias– a readiness to perceive
oneself favorably. Accept credit for good
deeds and shuck blame for bad deeds.
General Intelligence (g)
factor that Spearman and others believed underlies
specific mental abilities
measured by every task on an intelligence test
Factor Analysis
statistical procedure that identifies clusters of related
items (called factors) on a test
used to identify different dimensions of performance
that underlie one’s total score

through discussion within the group
Can increase prejudice, internet new medium
Good for self-help group situations
Groupthink
mode of thinking that occurs when the desire for
harmony in a decision-making group overrides

Fed by overconfidence, conformity, self-justification,
& group polarization.
• Intrinsic Motivation: Motivation coming
from within, not from external rewards;
based on personal enjoyment of a task
• Extrinsic Motivation: Based on obvious
external rewards, obligations, or similar
factors
Industrial and Organizational Psychologists – Industrial
psychologists focus on people and work. Organizational
psychologists study the behavior of people in
organizations, such as business firms. Industrial
psychology and organizational psychology are closely
related. Psychologists in these fields are often trained in
both areas.
• Industrial and organizational psychologists are employed
by business firms to improve working conditions and
increase worker output. They may assist in hiring,
training, and promoting employees. They may also devise
psychological tests for job applicants and conduct research
into the factors that contribute to job satisfaction. In
addition, some industrial and organizational psychologists
have counseling skills and help employees who have
problems on the job.
• Split Brain --a condition in which the
two hemispheres of the brain are isolated by
cutting the connecting fibers (mainly those
of the corpus callosum) between them
– Image projected to the left visual field of a
split-brained patient will be processed in the
right visual cortex.
Operant Conditioning
type of learning in which behavior is strengthened if followed by
reinforcement or diminished if followed by punishment
Shaping
operant conditioning procedure in which reinforcers
guide behavior toward closer approximations of a
desired goal
Law of Effect
Thorndike’s principle that behaviors followed by favorable
consequences become more likely, and behaviors followed by
unfavorable consequences become less likely
Memorizing lists
Primacy effect- Remembering the first four or
five items in a list because you have more time
to rehearse them
Recency effect- Recalling the last four or five
items because they were still in short-term
memory
When memorizing a list of words you are most
likely to forget the words in the middle of the
list.

What Are Phonemes?
PHONEME - shortest segment of speech,
which, if changed, would change the
meaning of a spoken word.
/bit/
/bait/
/beet/
Only 60 phonemes necessary to account for
all worlds’ languages!
English requires 48 phonemes.
Hawaiian requires only 11!
What Are Morphemes?
Morpheme - the shortest unit of spoken or written
language that carries meaning
Some morphemes are phonemes
(e.g., “I” and “a”)
Most are combos of 2 or more phonemes
Some morphemes are words
(e.g., “bat”)
Attention:
Process that transfers information from
sensory memory to short-term memory
Selective Attention
focus of conscious awareness on
particular stimulus (ex: cocktail party
effect– ability to hear only one voice
among many)
Kohlberg’s Moral Ladder
Postconventional
level
Morality of abstract
principles: to affirm
agreed-upon rights and
personal ethical principles
Conventional
level
Morality of law and
social rules: to gain
approval or avoid
disapproval
Preconventional
level
Morality of self-interest:
to avoid punishment
or gain concrete rewards
As moral
development
progresses, the
focus of concern
moves from the
self to the wider
social world.
Carol Gilligan’s Critique of
Kohlberg
Gilligan argues that Kohlberg’s rule-oriented conception of morality
has an orientation toward justice, which she implies is due to
stereotypical male thinking, whereas girls and women are more
likely to approach moral dilemmas with a “care” orientation
(Matthews, 1994).
Gilligan argues that moral reasoning of males is primarily
based on rational abstract principles, whereas the moral
reasoning of females is based on relationships and the
social context.
She bases her criticism on two things. First, that Kohlberg only
studied privileged white boys and men causing, in her opinion, a
biased opinion against women. Second, in his stage theory of moral
development, the male view of individual rights and rules was
considered a higher stage than women’s point of view of
development in terms of its caring effect on human relationships.
Memory
Short-Term Memory
activated memory that holds a few
items briefly
limited in capacity
look up a phone number, then quickly
dial before the information is forgotten
Long-Term Memory
the relatively permanent and limitless
storehouse of the memory system
Milgram Experiment
Milgram wanted to see if participants would
administer painful shocks to others merely
because an authority figure had instructed
them to do so. 60+% administered the
highest level of shock
Researchers at Swarthmore College
hypothesized that Milgram’s subjects could
inflict pain because they served in military
or were working class. They used young,
liberal, highly educated subjects: 88%
administered the highest level of shock.
Phenylketonuria (PKU)
A rare condition in which a baby is born without the ability to properly
break down an amino acid (protein) called phenylalanine.
Phenylketonuria (PKU) is inherited, which means it is passed down
through families. Both parents must pass on the defective gene in order
for a baby to have the condition. This is called an autosomal recessive
trait.
Phenylalanine plays a role in the body's production of melanin, the
pigment responsible for skin and hair color. Therefore, infants with the
condition often have lighter skin, hair, and eyes than brothers or sisters
without the disease.
Other symptoms may include:
Delayed mental and social skills
Head size significantly below normal
Hyperactivity
Jerking movements of the arms or legs
Mental retardation
Seizures
Skin rashes
Tremors
Unusual positioning of hands
Defense Mechanisms
Repression
the basic defense mechanism that banishes anxietyarousing thoughts, feelings, and memories from
consciousness– cannot retrieve the memories
Projection
defense mechanism by which people disguise their
own threatening impulses by attributing them to
others
Rationalization
defense mechanism that offers self-justifying
explanations in place of the real, more threatening,
unconscious reasons for one’s actions
Psychoactive Drugs
Opiates
opium and its derivatives
(morphine and heroin)
opiates depress neural
activity, temporarily lessening
pain and anxiety
Physiology of hunger
p. 428-430
Body chemistry affects hunger:
Glucose- when low we feel hungry
insulin- hormone that diminishes glucose by
storing it as fat
Brain monitors blood chemistry
(hypothalamus)
Lateral hypothalamus– initiates hunger
Ventromedial hypothalamus– depresses
hunger
Latent Learning
learning that occurs, but is not apparent until
there is an incentive to demonstrate it
Rats explored maze for 10 days. Then they
were reinforced with food at the end of the
maze. They quickly demonstrated their prior
learning and did as well as rats who had
always been reinforced.
Transduction
conversion of one form of energy to
another
in sensation, transforming of stimulus
energies into neural impulses
In vision, transduction happens in the
retina.
Semantic vs. Episodic Memory
Episodic
Chronological recollections of personal
experiences
Like an autobiography
Semantic
General knowledge, not tied to time when
learned
Like an encyclopedia
Renee Baillargeon
Found 4 month old infants will look longer
at a ball if it appears to roll through a
solid barrier, demonstrating that babies
seem to grasp basic physical laws
intuitively.
This challenged Piaget’s theory of object
permanence in Sensorimotor Stage
(cognitive development)
Social Psychology
• Bystander effect– the tendency of a
person to be less likely to give aid if other
people are present.
• Social loafing– tendency for people to
work less hard when sharing the workload
with others than when they are working
alone.
Classical
Conditioning
Biological processes
• Certain species are biologically
predisposed to learn a particular
association if it enhances their
survival.
Generalization
tendency for stimuli similar to CS to
elicit similar responses
EX: dog trained to salivate to bell can
be trained to salivate to light instead
Rational Emotive Therapy
(cont)
The main purpose of REBT is to help clients to identify and replace
absolutist philosophies, full of ‘musts’ and ‘shoulds’, with more flexible
ones; part of this includes learning to accept that all human beings
(including themselves) are fallible and learning to increase their
tolerance for frustration while aiming to achieve their goals.
Three primary insights:
While external events are of undoubted influence, psychological disturbance
is largely a matter of personal choice in the sense that individuals consciously
or unconsciously select both rational beliefs and irrational beliefs at (B) when
negative events occur at (A)
Past history and present life conditions strongly affect the person, but they do
not, in and of themselves, disturb the person; rather, it is the individual’s
responses which disturb them, and it is again a matter of individual choice
whether to maintain the philosophies at (B) which cause disturbance.
Modifying the philosophies at (B) requires persistence and hard work, but it
can be done.
Schizophrenia
• Defined as a class of disorders marked by
delusions, hallucinations, disorganized
speech, and deterioration of adaptive
behavior
• It primarily involves disturbances in
perception and thought, with corresponding
loss of the ability to function.
• Cognitive processes are severely
disrupted.
• Positive symptoms: Hallucinations,
disorganized and delusional talk,
inappropriate laughter, tears, or rage.
• Negative symptoms: toneless voices,
expressionless faces, mute

Social Thinking
Cognitive Dissonance Theory
we act to reduce the discomfort
(dissonance) we feel when two of our
thoughts (cognitions) are inconsistent
example- when we become aware that
our attitudes and our actions clash, we
can reduce the resulting dissonance by
changing our attitudes
Heuristics
Representativeness Heuristic
judging the likelihood of things in terms of how
well they seem to represent, or match, particular
prototypes
may lead one to ignore other relevant information
Availability Heuristic
estimating the likelihood of events based on their
availability in memory
if instances come readily to mind (perhaps
because of their vividness), we presume such
events are common
Example: airplane crash
Different dimensions or axes
Each axis reflects a different aspect of a patient’s
case:
Axis I- used to classify current symptoms
Axis II- used to describe developmental and longstanding personality disorders or maladaptive traits;
specific developmental disorders for children such as
mental retardation, autism, etc.
Axis III- used to describe physical disorders or general
medical conditions that are relevant to treatment
Axis IV- current stress level (based on the past year)
Axis V- adaptive functioning: 3 major areas– social
relations, occupational functioning, & use of leisure
time
EmotionLie Detectors
Polygraph
machine commonly used in attempts to
detect lies
Not widely used in courtrooms because the
type of arousal measured is much the same
for several emotions including lying– so it is
not always reliable.

also more error-prone--use of heuristics
The Cerebral Cortex
Aphasia
impairment of language, usually caused by left
hemisphere damage either to Broca’s area
(impairing speaking) or to Wernicke’s area
(impairing understanding)
Broca’s Area
an area of the left frontal lobe that directs the
muscle movements involved in speech
Wernicke’s Area
an area of the left temporal lobe involved in
language comprehension and expression
