Social Psychology

It is the study of how we think, influence, and relate

Social Thinking

Attribution Theory - Casual explanation for behavior

  • Behavior to situation or person's disposition

Fundamental Attribution Theory - Habit to underestimate the impact of a situation and overestimate the impact of personal disposition.

Teacher - commonly attributed to personality

Attitude - Belief or feeling that predisposes one to respond in a particular way to something

Action Guidance
  1. Minimal external pressure
  2. Attitude awareness
  3. Relevant attitude to behavior

Foot-in-the-door - Tendency for people who have first agreed to a small request to comply with a larger request


Door-in-face - Person says no to big request -> Agrees to small request


Cognitive-Dissonance Theory - We do not like when we have either conflicting attitudes or when our attitudes do not match our actions.

Clash -> Adapt attitude for balance

Social Influence


Conformity - Adjusting behavior or thinking to coincide with a group standard

Conditions:
  • One made to feel incompetent
  • Group has at least 3 people
  • Unanimous group
  • One admire's the group's status
  • No prior commitment
  • Person is observed
Reasons:
  • Normative - Approval or avoid disappointment
  • Informational - Willingness to accept others' opinions about reality

Social Facilitation - Better performance around others, especially with simple or well learned tasks. (Not with difficult or learning tasks)

Yerkes-Dodson Law - Optimal level of arousal for the best performance
Easy = High / Difficult = Low / Others = Moderate


Social Loafing -  Habit for people in a group to exert less effort in polling efforts toward a common goal then if they were individually accountable.


Deindividuation - Loss of self-awareness and self-restraint occurring in group situations that foster arousal and anonymity.


Group Polarization - Group's attitude is one of extremes; rarely normal.

EX: Black Panthers, KKK

Groupthink - Thinking that occurs when desire for harmony in decision-making overrides common sense.


Self-Fulfilling Prophecies - Person's belief about others leads one to act in ways that induce the others to appear to confirm that belief


Social Relations

Prejudice - An unjustifiable attitude towards a group of people

Stereotype - Generalized assumption about a group of people

Social Inequalities

  • Ingroup - "us", common identity
  • Outgroup - "them", the outcasts
  • Ingroup bias - tendency to believe own group is the best.

Scapegoat Theory - Prejudice provides an outlet for anger by providing someone to blame


Aggresion - Any physical or verbal behavior intended to hurt or destroy.

Biology - Genetics, Neutral Influences, Biochemical

Frustration-Aggressive Principle - Blocking of an attempt to achieve some goal creates anger, which leads to aggression.


Conflict - Perceived incompatibility of actions, goals, or ideas.

Social Trap - Situation where people must choose between act highly beneficial to self or moderately to all.

Attraction

Factors to gaining attraction:
  1. Proximity - Mere-exposure effect - More exposure = more attraction
  2. Reciprocal Liking - More likely to like someone who likes you
  3. Similarity - Opposites do not attract; Same pack flock together; Similarity breeds content.
  4. Liking through associations
  5. Physical Attractiveness

Love

  • Passionate - Aroused state of intense positive absorption of another
  • Compassionate - Deep affectionate attachment we feel in intertwined lives (Contains equity and self-disclosure

Altruism - Unselfish regard for the welfare of others.

Bystander Effect - Less willing to help if in vicinity of others

Social Exchange Theory - Our social behavior is an exchange process, which we maximize benefits and minimize costs.


Peacemaking - Give people superordinate(shared) goals that can only be achieved through cooperation. 

GRIT- (Graduated Reciprocated Initiatives in Tension Reduction)

Motivation and Emotion

Motivation -  Psychological Process that directs and maintains your behavior toward a goal.

Motive - Need, want, interest and desire that propel or drive people in certain directions

Instinct Theory - Motivated by our inborn automated behaviors.

Biological - Hunger, Thirst, Sex, Sleep
Social - Achievement, Order, Play, Autonomy, Affiliation

Drive Theory - Biological internal motivation (homeostasis)


Incentive Theory - Environmental motivation (not as much homeostasis, outside forces)


Drive-reduction Theory - Need or drive -> motivated to reduce need or drive; source of motivation lies within the person.

Hunger

  • Not from stomach - from hypothalamus
  • Why? Glucose - provides major source of energy for body tissues.
  • Insulin converts glucose to fat.

Hypothalamus
  • Lateral - Stimulation makes hunger; destroyed -> never be hungry
  • Ventromedial - Stimulation makes you feel full; destroyed -> no limit in hunger

Set Point Theory - Hypothalamus acts like a thermostat - maintain stable weight.

  • Lateral -> diet
  • Ventromedial -> gain weight

Eating Disorders

  • Bulimia Nervosa -  Binging ( eating large portions) and purging (ridding food) 
  • Anorexia - Be 85% below normal body weight, still see self as fat; mostly affects women
  • Obesity - Severely overweight to cause problems; mostly eating habits, some predisposed

Achievement Motivation

  • Intrinsic - Internal rewards (enjoyment, satisfaction)
  • Extrinsic - Outside rewards (grades, money); Great in short run
  • Over Justification - Reward for doing something you like to do results in you seeking reward as motivation for doing task. (Diminishes intrinsic motivation.

Management Theory

  • Theory X - Employees work for benefits or if threatened; Extrinsically motivated; Maslow's lower needs
  • Theory Y - Employees internally motivated to do good work; Maslow's higher needs; Policies should encourage this internal motive

Social Conflict Situations
  • Approach- Approach - 2 posi outcomes (only 1 chosen)
  • Avoidance-Avoidance - 2 nega outcomes (only 1 chosen)
  • Approach-Avoidance - Both options have posi and nega outcomes
  • Multi Approach -  Multi choices and outcomes

Emotion 

Response of the whole organism (physiological arousal, expressive behaviors, conscious experiences)

James-Lange Theory - Experience of emotion is awareness of physiological responses to emotion-arousing stimuli.


Cannon-Bard Theory - Stimuli stimulate both physiological response and subjective experience of emotion.


Two-Factor Theory - Experiencing emotion needs physical arousal and cognitive label.


Polygraph - Machine used to decipher lies by measuring perspiration, cardiovascular rates, and breathing changes (Physiological responses following emotion)


Amygdola - Neural key to fear learning

Catharsis - Emotional release

  • "Releasing" aggressive energy relieves aggressive urges.

Feel-good, do-good phenomenon - Tendency to be helpful when already in a good mood.


Adaption-Level Phenomenon - Tendency to form judgments relative to a "neutral" level (brightness, volume, level of income); defined by prior experience.


Relative Deprivation - Perception that one is worse off relative to those with whom one compares oneself.

Experimental methods in psychology tutorial





This video explains the experimental method in detail

Research Methods

Hypothesis - Expresses relationship between two variables

Variables

  • Independent - Whatever is being manipulated
  • Dependent - Measured
  • Confounding - Anything that manipulates, but is not the independent variable.
  • Operational - Explain what your hypothesis means

Definitions - Measured in 'real life' terms

Sampling -  Identify population subject; must be representative of population you study

Experimental Method - Prove casual relationships; Cause = Effect

  • Hawthorne Effect - Control group can change

Correlational Method - Expresses relationship between two variables; does not show causation

Survey Method - Most common study; measures correlation; cheap and fast

  • Needs a good random sample; low response rate

Naturalistic Observation - Watch subjects in their natural environment

Correlation Coefficient - A number that measures strength of a relationship; from -1 to +1; Weaker closer to zero.

Case Study - Detailed picture of one or few subjects

  • Great story; no correlational data - just descriptive. 

Statistics - Recording results from studies

  • Need common language for understanding
  • Descriptive Statistics - describes sets of data
  • Range - Distance from highest to lowest scores

Standard Deviation - Variance of scores around the mean

  • Higher variance = More Distribution Spread
Z scores - Unit that measures the distance of one score from the mean
  • + = Above the mean
  • - = Below the mean

Ethical Guidelines for Research

Animal Research

  • Clear purpose
  • Treated in a humane way
  • Acquire animals legally
  • Least amount of suffering possible

Human Research

  • No coercion, must be voluntary
  • Informed consent
  • Anonymity
  • No significant risk
  • Must debrief

  1. Phobias - Episode of intense dread
  2. GAD - (Generalized Anxiety Disorder) Constantly anxious; nervous system arousal. Worried, inadequate, oversensitive; isomnia
  3. Panic Disorder- 1 min. episode of dread: terror with chest pain, frightening sensations.
  4. OCD - Obsessions causes complusions to do a certain action
  5. PTSD - Flashbacks following someone's involvement in an extremely sensitive event. Memories can cause anxiety.

Somatoform Disorders - Psychological problem through physiological problem.

  • Hypochondriasis - Frequent complaints which doctors cannot find cause.
