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
To experience emotion one must: be physically
aroused cognitively
label the arousal
Cognitivelabel
“I’m afraid”
Fear(emotion)
Sight of oncoming
car(perception of
stimulus)
Poundingheart
(arousal)
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

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 self-actualisation
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
Typical Age Range
Description of Stage
Developmental Phenomena
Birth to nearly 2 years SensorimotorExperiencing the world through senses and actions (looking, touching, mouthing)
•Object permanence•Stranger anxiety
About 2 to 6 years
About 7 to 11 years
About 12 through adulthood
PreoperationalRepresenting things with words and images but lacking logical reasoning
•Pretend play•Egocentrism•Language development
Concrete operationalThinking logically about concrete events; grasping concrete analogies and performing arithmetical operations
•Conservation •Mathematical transformations
Formal operationalAbstract reasoning
•Abstract logic•Potential for moral reasoning
Piaget’s Stages of Cognitive Development
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 ultra-confidence 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
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 behaviorsImportant: Does not prove that one thing causes another, just proves there is a relationshipAlmost any two things or behaviors can be tested and proven related in some wayCorrelational 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 VariableVariable that you are trying to predictFactor observed and measured for a change, DV depends on changes in the independent variableUsually a test or measurement taken at the end of the experimentIn 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
Freud’s Elements of the Personality
ID• Unconscious energy• Basic drives• Sexual and aggressive instincts• Immediate gratification• Pleasure Principle• Instinctual/biological• Libidinal Energy

Rorschach Inkblot Test the most widely used projective test a set of 10 inkblots designed by
Hermann Rorschach seeks to identify people’s inner
feelings by analyzing their interpretations of the blots
Social Influence
Group Polarization enhancement of a group’s prevailing attitudes
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 realistic appraisal of alternatives
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.
Cones near center of retina fine detail and color vision daylight or well-lit conditions
Opponent-Process Theory- opposing retinal processes enable color vision

Gestalt--an organized whole tendency to integrate pieces of
information into meaningful wholes Grouping Principles
proximity--group nearby figures together similarity--group figures that are similar continuity--perceive continuous patterns closure--fill in gaps connectedness--spots, lines, and areas are
seen as unit when connected
Social Relations
Ingroup Bias tendency to favor one’s own group
Scapegoat Theory theory that prejudice provides an outlet for
anger by providing someone to blame Just-World Phenomenon/ Hypothesis
tendency of people to believe the world is just
people get what they deserve and deserve what they get
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 Only 60 phonemes necessary to account for all worlds’ languages!for all worlds’ languages!English requires 48 phonemes.
Hawaiian requires only 11!
What Are Morphemes?
MorphemeMorpheme - the shortest unit of spoken or writtenlanguage 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 memorySelective Attention
focus of conscious awareness on particular stimulus (ex: cocktail party effect– ability to hear only one voice among many)
Kohlberg’s Moral Ladder
As moral development progresses, the focus of concern moves from the self to the wider social world.
Morality of abstractprinciples: to affirm
agreed-upon rights andpersonal ethical principles
Morality of law andsocial rules: to gainapproval or avoid
disapproval
Morality of self-interest:to avoid punishment
or gain concrete rewards
Postconventionallevel
Conventional level
Preconventional level
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 anxiety-arousing 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 fatBrain 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

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 long-
standing 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
Emotion-Lie 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.
measures several of the physiological responses accompanying emotion perspiration cardiovascular breathing changes
Thinking
Algorithm methodical, logical rule or
procedure that guarantees solving a particular problem
contrasts with the usually speedier–but 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

Self-serving bias– a readiness to perceive oneself favorably. Accept credit for good deeds and shuck blame for bad deeds.
Personality Disorders• Psychologists consider people with personality disorders
“abnormal” because they seem unable to establish meaningful relationships with other people, to assume social responsibilities, or to adapt to their social environment.
