Economics: Unit 2-Chapter 7/8: CPI and Inflation Over Time

Consumer price Index (CPI): Measures the cost of the market basket of goods of a typical urban american family. 
  • CPI = ((Cost of market basket in a given year/Cost of market in a base year) * 100)
  • Real GDP is adjusted for inflation
Inflation: General rise of the price level

Deflation: Fall of the price level

Rate of Inflation = ((CPI(1) - CPI(2))/CPI(2)) * 100)

Types of Inflation
  1. Cost-Push Inflation: Higher production cost which increases prices
    • Usually the result of a supply shock
  2. Demand-Poll Inflation: Too many dealers chasing to few goods
    • Shortage driving up the prices
    • Overheated economy with excessive spending, but the same amount of goods.
  3. Political Panics: Occurs at recessions or depressions


How inflation hurts or helps


Hurt
  1. Lenders (loan at a fixed rate)
  2. People with fixed income (elderly, disabled)
  3. Savors
  4. People with a fixed wage
Help
  1. Debtors
  2. Business where the price of the product increases faster than the price of resources.
Unemployment: The percentage of people who do not have jobs but their in the labor force
  • Lobar Force = employed + unemployed
Not in the labor Force
  • Kids who are 16 or younger
  • Military Personnel
  • mentally Insane
  • Those licked up in prison
  • Stay at home moms and dads
  • Full-time students
  • Retired People
  • Discouraged


Employed vs. Unemployed 


Employed: People 16 and older who have a job

Unemployed: People 16 and older who have actively looked for a job for at leas 2 weeks

Unemployment Rate = (number of unemployed/labor force) * 100 


Types of Unemployment

  1. Seasonal 
    • Mall Santa during Christmas
    • Concession stands for Texans
    • School buses
    • Lifeguards
  2. Frictional: Between jobs
    • Leave McDonald's to work at a University
  3. Structural: Associated with a lack of skill or a declining industry
    • Technology has changed
  4. Cyclical: Bad for society and individuals
    • Associated with the business cycle
    • You have a recession
Full Employment: Occurs when their is no cyclical unemployment present in the economy

NRU (Natural Rate of Unemployment) = 4% to 5%

Okun's Law: For every 1% of unemployment above the NRU causes a 2% decline in the RGDP.


Economics: Unit 2: Chapter 7: GDP, Real GDP, and Nominal GDP

GDP (Gross Domestic Product): The total value of all final goods and services produced within a country's border within a given year.



GNP (Gross National Product): The total value of all final goods and services produced by Americans in a given year.

What is included in GDP?
  • Final goods and services
  • Income earned
  • Interest payments on corporate bonds
  • Current production of final goods and services
  • Unsold outputs (business inventories)
What is not included in GDP?
  • Intermediate goods
  • Transfer payments (public or private)
    • Scholarships, social security
  • Purchases of stocks and bonds
  • Used or second handed sales (avoid double count)
  • Non-market transactions
    • Babysitting
    • Illegal drugs
    • Prostitution
    • Doing your own house work or repairs
    • Growing your own products for personal consumption

How do you calculate GDP?
                                 

Expenditure Approach
Income Approach
GDP=C+Ig+G+Xn
GDP=W+R+I+P+Statistical Adjustments
Used when calculating goods and services
Used for calculating factors of production

                        
C=Personal Consumption (anything you buy)           
W=Wages (Compensation of employees , salary)
Ig= Gross Private Domestic Investment 
·        Factory Equipment
·        New construction of homes and businesses
·        Tools and machines

R= Rents (rental income)           
G=Government Spending
I=Interest (interest income)
Xn= Net exports (exports-imports)
P=Payments (proprietors income)

Budget Deficit: The total amount of government borrows within a year. 
  • Total government spending exceeds tax and fee revenue
  • Equation: (Transfer Payments + Government Purchases - Government Tax and Fee Collection)
  • If the answer is negative, it is a budget surplus
  • If the answer is positive, it is a budget deficit


Trade = (exports - imports)
  • If the answer is positive, it is a surplus
  • If the answer is negative, it is a deficit
National Income Equations:
  • (GDP - indirect business tax - depreciation - net foreign factor)
  • (Compensation of employees + proprietors income + rental income + interest income + corporate profit)
Disposable Personal Income = (National Income - Household Taxes + Government Transfer Payments)

Net Domestic Product = (GDP - Depreciation) (Depreciation can also be called consumption of fixed capital)

Net National Product = (GNP - Depreciation) (Depreciation can also be called consumption of fixed capital)

GNP = (GDP + Net Foreign factor Payment)

Normal GDP: The value of output produced at current prices
  • Nominal GDP = Price * Quantity
Real GDP: The real value of output produced at constant or based year prices.
  • Real GDP = Price * Quantity
  • Nominal GDP can increase year to year. If either output or prices increase, Real GDP can only increase if output increases.
Gross Private Domestic Investment = (Net private domestic investment + Depreciation) 

To measure economic growth, find RGDP.
To measure inflation, find NGDP.


Ex. In year 1, 10 computers are sold at $2000 each, and 15 televisions were sold at $500 each. In year 2, 17 computers were sold at $ 2200 each, and 20 televisions were sold at $550 each. 

Nominal GDP is (17*2200) + (20*550) = $48400

Real GDP is (17*2000)+(20*500) = $44000


GDP Deflator = ((Nominal GDP/Real GDP) *100)
  • In base year, GDP is always equal to 100
  • For year after the base year, GDP deflator is greater than 100
  • For years before the base year, GDP deflator is less than 100

Economics: Unit 2-Chapter 2/5/6: Circular Flow

Circular Flow Model: Represents the flow of money, goods, and services in the economy

Factor Market/Resource Market: Factors of production; we sell our resources to businesses.

Product Market/Goods Market: Where goods and services are bought and sold.

Households: Where a person or group shares an income.

Firms/Businesses: An organization that produces goods and services for sale.

The "Big Picture"


Factor Market: Firms buy. Households sale

Households: Sell Resources, Buy Products

Product Market: Firms Sell, Households buy

Firms/Business: Buy resources, Sell Products

The Government: Both Consumer and Producer in markets

Rest of the World


  • Households supply the Factor Market with factors of production (land, labor, capital, entrepreneurship)
  • The Factor Market are then demanded factors of production (land, labor, capital, entrepreneurship) from Firms/Businesses
  • Firms/Businesses supply the Product Market with Goods and Services.
  • The Product Market are demanded Goods and Services from Households.
  • Households give consumption expenditures to the Product Market
  • The Product Market give revenue to Firms/Businesses
  • Firms/Businesses give "cost" to the Factor Market
  • The Factor Market give money income (wages, rents, interest, payments) to Households
  • The Government gives Goods and Services to both Households and Firms/Businesses
  • The Government gives expenditures tot he Product and Factor Market
  • The Government receives Taxes from Firms/Business and Households
  • The Government receives Resources from the Factor Market
  • The Government receives Goods and Services from the Product Market
  • The Product Market gives U.S. Exports and U.S. Expenditures to the Rest of the World
  • The Rest of the World gives the Product Market Foreign Expenditures and U.S. Imports

Psychology: Unit 2-Research, Stats, Testing & Intelligence

Hindsight Bias: The tendency to believe, after learning the outcome, that you knew all along.

Overconfidence: We tend to think we know more than we do.

The Barnum Effect: It is the tendency for people to accept very general or vague characterizations of themselves, and take them to be accurate.

Applied vs. Basic Research


Applied Research has clear, practical applications. "You can use it!!!"

Basic Research explores question that you may be curious about, but not intended to be immediately used. 

Hypothesis: Expresses a relationship between 2 variables.
  • A variable is anything that can vary among participants in a  study. 


Independent Variable: Whatever is being manipulated in the experiment. (Usually a drug if it is involved) 

Dependent Variable: Whatever is being measured int the experiment. (Usually the effect of the drug if it is involved)

Operational Definition: Explains what you mean in your hypothesis.
  • How will the variables be measured in "real life" terms. 

Types of Research


There are 3 types of research: descriptive, correlational, and experimental

Descriptive Research
  • We describe what we see
  • Any research that observes and records
  • Types of Descriptive Research
    • Case Studies: A detailed picture of one or a few subjects
    • The Survey
      • Most common type of study in psychology
      • Measures correlation
      • Cheap and fast
      • use interview, mail, phone, internet, etc.
      • Low response rate
    • Naturalistic Observation

Random Sampling: Identify the population you want to study.
  • The sample must be representative of the population you want to study.


Why do we sample?
  • One reason is the False Consensus Effect, the tendency to overestimate the extent to which others share our beliefs and behaviors.

Survey Method: The Bad
  •  Low Response Rate
  • People Lie or just misinterpret themselves
  • Wording Effects

Naturalistic ObservationWatch subjects in their naturalistic Environment
  • Do not manipulate the environment


Hawthorne Effect: Just the fact that you know you are in an experiment can cause change
  • Even the control group may experience change

Correlational Research


Correlational Method: Correlation expresses a relationship between 2 variables
  • Does not show causation
  • Measured using a correlation coefficient
o   A number that measures the strength of a relationship
o   Range is from -1 to +1
o   The relationship gets weaker the closer you get to zero

Here are some examples to try out. Which is a stronger correlation?
  • -.13 or +.37
  • -.72 or +.59

Types of Correlation


Positive Correlation: The variables go in the same direction

Negative Correlation: The variables go in the opposite direction.

Experimental Research: Explores cause and effect relationship
  • Ex. Eating to many bananas causes constipation


Here is a small activity you can do to help you know the research methods better
  • Choose what you believe to be the preferred method of study for each hypothesis below. If a problem can be studies using more than one approach, choose the method with the greater precision. Choose from the following:

N (Naturalistic Observation)         S (Survey)             C (Case Study)           E (Experimental Study)

  1. Jogging increases lung capacity. ______
  2. Individuals having one or more significant hobbies report more jobs satisfaction than individuals having no hobbies. _____
  3. A person cannot learn language if they are not exposed to it in the first five years of life. _____
  4. Unmarried cab drivers talk more with their customers than do married cab drivers. _____
  5. The purchase of tranquilizers increases during monetary crisis. _____
  6. Apes are capable of understanding language _____
  7. More men than women report fantasies of making large sums of money. _____ 
  8. Work productivity increases when workers are allowed flexible hours. _____


After you have completed the activity, check your answers.
  1. E
  2. S
  3. C
  4. N
  5. N
  6. C
  7. S
  8. E

Independent Variable (IV): The experimental factor that is being manipulated; the variable whose effect is being studied

Dependent Variable (DV): The variable that may change in response to manipulations of the IV; the variable that is being measured.

Experimental vs. Control Groups


Experimental Group: The condition of an experiment that exposes participants to the treatment.
  • Receives the IV
Control Group: The condition of the experiment that serves as a comparison for evaluating the effect of the treatment


Types of Experimental Methods


Blind Study: Subjects are unaware if assigned to experimental or control groups

Double-Blind Study: Neither subjects nor experimenters know which group is control or experimental



Descriptive vs. Inferential Statistics


Descriptive Statistics: Describe the results of research
  • Ex. 400 likely voters surveyed by phone on October 20. Of these, 230 said they will vote for Obama.

Inferential Statistics: Are used to make an inference or draw a conclusion beyond the raw data
  • Ex. Obama will win the election

Measures of Central Tendency


Central Tendency: Where does the center of the data tend to be?

Mode: The most frequently occurring score in a distribution
  • Ex. 2,2,2,5,5,6,7,7,7,7,7,9,10.
Mean: the arithmetic average of scores of distribution
  • Add all the scores together, then divide the number of scores
Range: The difference between the highest and lowest scores in distribution.

Standard Deviation: A computed measure of how much scores vary around the mean.
  • High standard deviation means scores are spread out
  • Low standard deviation means scores are close together

Psychology: Unit 1-Psychological Disorders and Therapies

Psychological Disorder: A "harmful dysfunction" in which behavior is judges to be atypical, disturbing, maladaptive, and unjustifiable.

Current Perspective:
  • Medical Perspective: psychological disorders are sickness and can be diagnosed, treated and cured. 
  • Bio-Psycho-Social Perspective: Assumes biological, psychological and socio-cultural factors combine to interact causing psychological disorders,
    • Used to be called Diathesis-Stress Model: diathesis meaning disposition and stress meaning environment. 

Classifying Psychological Disorders

  • DSM-IV: Diagnostic Statistical Manual of Mental Disorders--the big book of disorders.
  • Neurotic disorders: Distressing but one can still function in society and act rationally. 
  • Psychotic Disorders: Person loses contact with reality, experiences distorted perceptions. 

Anxiety Disorders

Anxiety Disorders: A group of conditions where the primary symptoms are anxiety or defenses against anxiety.

Psychological Therapies

Psychological Therapy: Treatments based on psychological principles

Bio-medical Therapy: Treatment that focus on altering the brain with drugs, psycho-surgery, or electro-convulsive therapy.
  • It used to be that if someone exhibited abnormal behavior, they were institutionalized.
  • Because of new drugs and better therapy, the US went to a policy of de-institutionalization. 
Psychoanalysis: 
  • Freud's therapy
  • Freud used free association, hypnosis and dream interpretation to gain insight into the client's unconscious. 
Humanistic Therapy: Focuses on people's potential for self-fulfillment (self-educate)
  • Focus on the present and future
  • Focus on conscious thoughts
  • Take responsibility for your actions-instead of blaming childhood anxieties. 
Group Therapy

Self-Help Support Group: NA, sex offenders

Client (person) Centered Therapy: 
  • Developed by Carl Rogers
  • Therapists should use genuineness, acceptance, and empathy to show unconditional positive regard toward their clients. 
Behavior Therapy: Therapies that apples learning principles to the elimination of unwanted behaviors. The behaviors re the problems-so we must change the behaviors. 

Systematic Desensitization: A type of counter-conditioning that associate a pleasant related state with gradually increasing anxiety-triggering stimuli. 

Exposure Therapy: A form of desensitization where the client directly confronts the anxiety provoking stimulus. 

Aversive Therapy/Conditioning: A type of counter-conditioning that associates an unpleasant state with an unwanted behavior.

Token Economy: An operant conditioning procedure that rewards a desired behavior. 

Cognitive Therapy: A therapy that teaches people new, more adaptive ways of thinking and acting; based on the assumption that thoughts intervene between events and our emotional reactions. 


The Bio-medical Therapies

Psycho-pharmacology: The study of the effects of drugs on mind and behavior.

Anti-psychotic drugs: 
  • A class of medicine used to treat psychosis and other mental and emotional conditions. 
  • These drugs are beginning to help schizophrenia with both positive and negative symptoms. 
  • These drugs (Thorazine) often have powerful side effects.
Anti-anxiety drugs: 
  • Includes drugs like Valium and Librium
  • Like alcohol, they depress nervous system activity
  • Most widely abused drug.  
Anti-depressant drugs:
  • Lift you up out of depression
  • Most increase neurotransmitter nor-epinephrine
Prozac, Pax, Zolaft: Work by blocking serotonin re-uptake

Electroconvulosive Therapy: Bio-medical Therapy for severely depressed patients in which brief electric current is sent through the brain of an anesthetized patient. 

Psychology: Unit 1-Personality

Personality: An individual's characteristic pattern of thinking, feeling, and acting.

Psychoanalytical Perspective: In his clinical practice, Freud encountered patients suffering fr oil m nervous disorders. Their complaints could not be explained in terms of purely physical causes.
Freud's clinical experience led him to develop the first comprehensive theory of personality, which included unconscious mind, psycho-sexual stages, and defense mechanisms.

Exploring the Unconscious: A reservoir (unconscious mind) of mostly unacceptable thoughts, wishes, feelings, and memories. Freud asked patients to say whatever came to their minds (free association) in order to tap the unconscious.

Dream Analysis: Another method to analyze the unconscious mind is through interpreting manifest and latent contents of dreams.

Psychoanalysis: The process of free association (chain of thoughts) leads to painful, embarrassing unconscious memories. Once these memories are retrieved and released the patient feels better.

Model of Mind: The mind is like an iceberg. It is mostly hidden, and below the surface lies the unconscious mind. The preconscious stores temporary memories.

Personality Structure: Personality develops as a result  of our efforts to resolve conflicts between our biological impulses (id) and social restraints (superego).

Id, Ego, and Superego: The Id unconsciously strives to satisfy basic sexual and aggressive drives, operating on the pleasure principle, demanding immediate gratification.

Personality Development: Freud believed that personality formed during the first few years of life divided into psycho sexual stages. During these stages the id's pleasure-seeking energies focus on pleasure sensitive body areas called erogenous zone.


Psychosexual Stages Stage:
-Oral (0-18 months): Pleasure centers on the mouth-sucking, biting, chewing.
-Anal (18-36 months): Pleasure focuses on bow and bladder elimination; coping with demand for control.
-Phallic (3-6 years): Pleasure zone in genitals; coping witb incestuous sexual feelings.
-Latency (6-puberty): Dormant sexual feelings.
-Genital (puberty on): Maturation of sexual interests

Oedipus Complex: A boy's sexual desire for his mother and feelings of jealousy and hatred for the father. A girl's desire for her father is called the Electra Complex

Identification: Children cope with threatening feelings by identifying them and by identifying with the rival parent. Through this process of identification, their superego gains strength that incorporates their parent's values.

Defense Mechanisms: The ego's protective methods of reducing anxiety by unconsciously distorting reality.
  1. Repression banishes anxiety-arousing thoughts, feelings, and memories from consciousness.
  2. Regression leads an individual faced with anxiety to retreat to a more infantile psychosexual stage.
  3. Reaction Formation causes the go to unconsciously switch unacceptable impulses into their opposites. People may express feelings of purity when they may be suffering anxiety from unconscious feelings about sex.
  4. Projection leads people to disguise their own threatening impulses by attributing them to others.
  5. Rationalization offers self-justifying explanations in place of the real, more threatening, unconscious reasons for one's actions.
  6. Displacement shifts sexual or aggressive impulses toward a more acceptable or less threatening object or person, redirecting anger toward a safer outlet.  
The Neo-Freudians:
  • Like Freud, Adler believed in childhood tensions. However, these tensions were social in nature and not sexual. A child struggles with an inferiority complex during growth and strives for superiority and power.
  • Like Adler, Horney believes in the social aspects of childhood growth and development. She encountered Freud's assumption that women have weak superegos and suffer from "penis envy".
  • Jung believed in the collective unconscious, which contained a common reservoir of images derived from our species past. This is why many cultures share a certain myth and images such as the mother being a symbol of nurturance.
Assessing Unconscious Processes: Evaluating personality from an unconscious mind's perspective would require a psychological instrument (projective tests) that would reveal the hidden unconscious mind.  

Thematic Apperception Test (TAT): Developed by Henry Murray, the TAT is a projective test in which people express their inner feelings and interests through the stories they make up about ambiguous scenes.

Rorschach Inkblot Test: The most widely used projective test uses a set of 10 inkblots ans was designed by Hermann Rorschech. It seeks to identify people's inner feelings by analyzing conscious interpretations of the blots.

Projective Tests Criticism: Critics argue that projective tests lack both reliability (consistency of results) and validity (predicting what it is suppose to do).

Evaluating the Psychoanalytical Perspective: Personality develops throughout life and is not fixed in childhood.
  • Freud under emphasized peer influence on the individual which may be as powerful as parental influence.
  • Gender identity may develop before 5-6 years of age.
  • There may be other reasons for dreams besides wish fulfillment.
  • Verbal slips can be explained on the basis of cognitive processing of verbal choices.
  • Suppresses sexuality leads to psychological disorders. Sexual inhibition has decreased, but psychological disorders have not. Freud's psychoanalytical theory rests on the repression of painful experiences into the unconscious mind. 
The Modern Unconscious Mind: Modern Research shows the existence of non-conscious information processing. This involves:
  1. Schemas that automatically control perceptions and interpretations.
  2. The right-hemisphere activity that enables the split-brain patient's left hand to carry out an instruction the patient cannot verbalize.
  3. Parallel Processing during vision and thinking.
  4. Implicit memories
  5. Emotions that activate instantly without consciousness.
  6. Self-Concept and stereotypes that unconsciously influence us.
Evaluating the Psychoanalytical Perspective: The scientific merits of Freud's theory have been criticized. Psychoanalysis is meagerly testable. Most of its concepts arise out of clinical practice, which are the after-the-fact explanation.

Humanistic Perspective: By the 1960's, psychologists became discontent with Freud's negativity and the mechanistic psychology of the behaviorists.

Self-Actualizing Person: Maslow proposed that we as individuals are motivated by a hierarchy of needs. Beginning with physiological needs. we try to reach the state of self-actualization-fulfilling our potential.

Person-Centered Perspective: Carl Rogers also believed in an individual's elf-actualization tendencies. He said that unconditional positive regard is an attitude of acceptance of others despite their failings.

Assessing the Self: In an effort to assess personality, Rogers asked people to describe themselves as they would like to be (ideal) and as they actually are (real). If the two descriptions were close the individual had a positive self concept.

Evaluating the Humanistic Perspective: Humanistic psychology has a pervasive impact on counseling, education, child-rearing,and management with its emphasis on positive self-concept, empathy, and the thought that people are basically good and can improve. 
  1. Concepts in humanistic psychology are vague and subjective and lack scientific basis.
  2. The individualism encouraged can lead to self-indulgences, selfishness, and an erosion of moral restraints.
  3. Humanistic psychology fails to appreciate the reality of our human capacity for evil. It lacks adequate balance between realistic optimism and despair.
Examples of Traits: Honest, Dependable, Moody, Impulsive.

Exploring Traits: Each Personality is uniquely made up of multiple traits. Allport and Odbert (1936), identifies almost 18,000 words representing traits. One way to condense the immense list of personality traits is through factor analysis, a statistical approach used to describe ad relate personality traits.

Factor Analysis: Hans and Sybil Eysenck suggested that personality could be reduced down to two polar dimensions, extroversion-introversion and emotional stability-instability.

Biology and Personality: Personality dimensions are influenced by genes.
  1. Brain-imaging procedures show that extroverts seek stimulation because their normal brain arousal is relatively low.
  2. Genes also influence our temperament and behavioral style. Differences in children's shyness and inhibition may be attributed to autonomic nervous system reactivity.
Assessing Traits: Personality inventories are questionnaires (often with true-false or agree-disagree items) designed to gauge a wide range of feelings and behaviors assessing several traits at once.

MMPI: The Minnesota Multiphasic Personality Inventory is the most widely researched and clinically used of all personality tests. It was originally developed to identify emotional disorders.



The Big Five Factors: Today's traits researchers believe that earlier trait dimensions, such as Eysencks' personality dimensions, fail to tell the whole story. So, an expanded range (five factors) of trait does a better job of assessment.


Trait Dimensions
Endpoints of the Dimensions
Conscientiousness

Organized------------------------------Disorganized
Careful--------------------------------------  Careless
Disciplined---------------------------------Impulsive
Agreeableness
Soft-Hearted---------------------------------Ruthless
Trusting------------------------------------Suspicious

Questions about the Big Five:
  1. How stable are these traits?
    • Quite stable in adulthood, however, they change over development.
  2. How heritable are they?
    • Fifty percent so for each trait.
  3. How about other cultures?
    • These traits are common across cultures.
Evaluating Trait Perspective: The person-situation controversy Walter Mischel (1968, 1984, 2004) points out that traits may be enduring, but the resulting behavior in various situations is different. Therefore, traits are not good predictors of behavior. 

The Person-Situation Controversy: Trait theorists argue that behaviors from a situation may be different, but average behavior remains the same. Therefore, traits matter. Traits are socially significant and influence our health, thinking, and performance (Gosling et al.,2000).

Consistency of Expressive Style: Expressive styles in speaking and gestures demonstrate trait consistency. Observers are able to judge people's behavior and feelings in as little as 30 seconds and in one particular case as little as 2 seconds. 

Social-Cognitive Perspective: Bandura (1986, 2001, 2005) believes that personality is the result of an interaction that takes place between a person and their social context. 

Individuals and Environments: Specific ways in which individuals and environments interact.
  1. Different people choose different environments.
  2. Our personalities shape how we react to events.
  3. Our personalities shape situations. 
Behavior: Behavior emerges from an interplay of external and internal influences.

Personal Control
-Social-cognitive emphasize  our sense of persional control, whether we control the environment or the environment controls us.
-External locus of control refers to the perception that chance or outside forces beyond our personal control determine our fate.
-Internal locus of control refers to the perception that we can control our own fate

Learned Helplessness: When unable to avoid repeated adverse events an animal or human learns helplessness.

Optimism vs. Pessimism: An optimistic attributal style is your way of explaining positive or negative events. Positive psychology aims to discover and promote conditions that enable individuals and communities to thrive.

Positive Psychology and Humanistic Psychology: Positive psychology, such as humanistic psychology, attempts to foster human fulfillment. Positive psychology, in addition, seeks positive subjective well-being. positive character, and positive social groups. 

Assessing Behavior in Situations: Social-Cognitive psychologists observe people in realistic and simulated situations because they find that it is the best way to predict the behavior of others in similar situations.

Evaluating the Social-Cognitive Perspective: The social-cognitive perspective on personality sensitizes researchers to the effects of situations on and by individuals. It builds on learning and cognition research. Critics say that social-cognitive psychologists pay a lot of attention to the situation and pay less attention to the individual, his unconscious mind, his emotions, and his genetics.

Exploring the Self: Research on the self has a long history because the self organizes thinking, feelings, and actions and is a critical part of our personality. 
  1. Research focuses on the different selves we possess. Some we dream and others we desire.
  2. Research studies how we overestimate our concern that others evaluate our appearance, performance, and blunders (spotlight effect).
Benefits of Self-Esteem: Malow and Rogers argued that a successful life results from a healthy self-image (self-esteem). The following are two reasons why low self-esteem results in personal problems.
  1. When self-esteem is deflated, we view ourselves and others critically. 
  2. Low self-esteem reflects reality, our failure in meeting challenges, or surmounting difficulties.  
Culture and Self-Esteem: People maintain their self-esteem even with a low status by valuing things they achieve and comparing themselves to people with similar positions.
