Social psychology — we are social species

Solitary species vs social species (humans only ability)

  • Our ability to cooperate is one of the major reasons we succeed as a species

  • But comes with strings attached

New cards

Social Psychology

The branch of psychology that studies how individuals think about, influence and relate to other people

3
New cards

Misinfos about social psychology

• Most view being influenced as weakness (they shouldn’t)

• Most believe highly resistant to social pressures (they’re wrong)

• In certain cases, both tendencies could be a “strength

• Achieve group cohesion + finish tasks

• We are continually participating in social networks

4
New cards

Social networks

  • Humans have history of working in small groups (e.g. tribes) (~150 members, according to Dunbar)

  • Quantity not all that matters — quality matters too

  • While overall network large, number of close relationships modest

  • Networks can change with time (technology, stress, age)

5
New cards

Socioemotional selectivity theory

Predicts older adults have fewer relationships — based on different motives (i.e. emotion regulation)

  • older —→ emotional regulation

  • young —→ many reasons

<p>Predicts older adults have fewer relationships — based on different motives (i.e. emotion regulation)</p><ul><li><p>older —→ emotional regulation</p></li><li><p>young —→ many reasons</p></li></ul><p></p>
6
New cards

Need to belong theory

Humans have a fundamental drive to form/maintain relationships

.

Absence of relationships might be harmful

  • Solitary confinement in prison + lockdowns (effects differ by age)

  • quality of relationships also matter

.

Few experimental studies of isolation (most are correlational)

  • one study only 1 of 5 subjects lasted > 3 days

  • subjects given belief they would end up alone showed unhealthy behaviours, procrastination, impaired cognition

7
New cards

Loneliness

Loneliness is related to, but distinct from, isolation

  • isolation = lack of social contact, not necessarily bad

  • loneliness = feeling lack of connection, inherently negative

  • both related to health outcomes (mental, physical)

.

Reports of loneliness increasing (“epidemic”)

  • Before COVID: 1/3, with 1/12 cases being severe

  • we spend more time alone now

.

Not easily treatable

  • forced interaction

  • support networks

  • social skills training

8
New cards

Being a part of a group can change your behavior

9
New cards

Groups: Social contagion

When a belief rapidly spreads throughout a group

  • though is often pejorative (not bad or good), impact depends on belief

.

Related term: mass hysteria

  • Large group, behaviors both irrational and harmful

  • Many potential examples

    • Urban legends, UFO reports

    • emotional contagions well-accepted; clinical contagions (e.g. dissociative identity disorder and depression) suggested but more controversial

10
New cards

Dissociative Identity Disorder

Affected person claims to have at least two identities

  • may alternatively display

  • memory impairment of prior states common

.

More common in women (reason unknown)

.

Controversial

  • cultural factors

  • improper interventions

  • misdiagnosed?

11
New cards

Groups: Social loafing

Tendency to put in less effort/do less work in groups

  • Possible variation of bystander effect (e.g. diffusion of responsibility)

  • Many examples:

    • cheerleaders less loud in groups

    • pull less hard on rope

    • generate fewer/less creative ideas

  • May be less evident in collectivist societies

12
New cards

Groups: Deindividuation

Engage in behavior atypical for us but consistent w/contextual norms

.

Key factors are a feeling of anonymity and lack of accountability

.

Example: behaviour when masked

  • child wearing masks more likely to take ‘forbidden candy’

  • presence of mirror may reduce

.

Major potential examples: online behavior, crowd behavior, stanford prison study

13
New cards

1 – Online behavior

Sometimes cute + funny (e.g. hijacking online polls and voting for ridiculous options)

.

Sometimes cruel + terrifying (e.g. cyber-bullying)

  • males more frequent perpertrators

  • associated with psychological + academic problems in victims

  • common: much wider age spectrum

14
New cards

Online behavior — cont.

Though it often involves deindividuation, it does not require it

.

In some cases: people used real identities and articulated real beliefs

  • Typical behavior, no anonymity but possibility of accountability

.

Motivating factor is likely a desire to enforce certain ideals: cultural, political and religious values

  • think youre speaking the truth

15
New cards

2 – Deindividuation in Crowds

  • People routinely gather in large groups

  • One of the most striking example of this is protests

    • Many throughout history, some of which include 10 000+ people in one place

  • Most crowds and protests are peaceful

16
New cards

3 – The Stanford Prison Study

Observational, not experimental

  • 24 participants randomly assigned to roles of prisoner/guard, head of study was superintendent

  • people reportedly became consumed in roles, losing identity and behaving atypically

  • very popular and controversial

17
New cards

The Stanford Prison Study — cont.

Though initially most participants believed that they were incapable of cruelty, cruel behaviors did emerge

  • Some guards (~33%) showed aggressive and concerning behaviors (humiliation, do push-ups, strip naked and clean toilets with bare hands)

  • supposed to be two weeks but was ended after six days

18
New cards

Criticisms of stanford prison study

  • Small sample size (n)

  • Selection bias (whoever responded to the ad)

  • Demand characteristics (some ideas of what the experimenter wants) + observer effect (know experimenter is watching)

  • Emphasis on qualitative, anecdotal reports: difficult to verify and analyze quantitatively

  • Experimenter (Zimbardo) was involved (superint.)

  • Numerous ethical issues (never fully repeated)

19
New cards

When discussing influence…Obedience and conformity

Obedience: Listening to a figure of authority (e.g. a persuasive politician or a strong sergeant)

  • generally explicit

.

Conformity: Adopting the predominant belief or behavior of a group due to pressure from that group

  • generally implicit

.

Not by themselves bad

  • issues from blindly following without asking questions

20
New cards

Obedience: Milgram’s story

  • Child of Jewish parents who grew up through World War 2

  • Preoccupied with atrocities of Holocaust and wondered how people could commit such horrific acts

  • Prevailing view at the time was such acts were due to “twisted minds” (bad people do bad things)

  • However, Milgram’s research suggested that situational factors could have also played a role (bad situations, rather than bad people)

21
New cards

Milgram Experiment

  • (E) is an experimenter overseeing everything

  • Participant acts as a teacher (T) who asks the learner (L) questions

  • (T) is told to give (L) a shock for wrong answers*

  • (L) is an actor who pretends to be shocked and protests to the shocks

(confederate: working with the study)

<ul><li><p><strong>(E)</strong> is an experimenter overseeing everything</p></li><li><p>Participant acts as a teacher <strong>(T)</strong> who asks the learner <strong>(L)</strong> questions</p></li><li><p><strong>(T)</strong> is told to give <strong>(L) </strong>a shock for wrong answers*</p></li><li><p><strong>(L) </strong>is an actor who pretends to be shocked and protests to the shocks</p></li></ul><p>(confederate: working with the study)</p>
22
New cards

Important Factors of Milgrim experiment — saying no

Proximity + contact with learner reduced willingness to give shocks

Some participants stopped complying as intensity increased (15 to 450V), but majority (66%) stayed

When a confederate scientist was present and disagreed with the experimenter, compliance was 0%

  • value of dissenting voices

  • when someone else disagrees, more comfortable disagreeing ourselves

23
New cards

Important Factors of Milgrim experiment — performance

  • No major cultural differences or gender differences

  • Compliance is not related to sadistic tendencies, but is related to other traits (obedience and authoritarianism)

  • Failure to comply is related to moral development, though this relationship is not especially strong

  • Despite many increasing criticism of late (e.g. ethics, internal validity), it does have value

24
New cards

Conformity: Asch’s study on conformity

Subjects participated in a study w/several confederates

.

Subject had to declare which of 3 lines was longer

.

Before the subject made their judgement, they heard several confederates make an incorrect judgment

  • subjects readily conformed to wrong opinion

  • rates of conformity increased w/group size to a point (ceiling effect)

25
New cards

On conformity

  • We all show some capacity; the question is how much and how often

  • Low self-esteem predicts high conformity

  • Cultural differences possible; conformity may be greater in collectivist cultures than in individualistic cultures

  • Gender differences in conformity are disputed

26
New cards

Individualism vs. Collectivism

Index reflects the degree to which people are integrated into groups

  • High index of individualism = individualistic society

  • Low index of individualism = collectivist society

<p>Index reflects the degree to which people are integrated into groups</p><ul><li><p>High index of individualism = individualistic society</p></li><li><p>Low index of individualism = collectivist society</p></li></ul><p></p>
27
New cards

Individualism vs. Collectivism — details

Western societies — tend toward individualism

Eastern societies — tend toward collectivism

.

May infulence many behaviors

  • family attitudes

  • facial expressions

  • prosocial behaviors

  • creativity

.

Must avoid stereotypes and focus on what is scientifically proven

  • findings often controversial

28
New cards

Cults

Groups with intense and unquestioning devotion to a single cause

  • NXIVM, heaven’s gate, etc

.

Difficult to study due to secretive nature

.

Several consistent features:

  • persuasive leader who inspires loyalty

  • members disconnected from outside world

  • questions/dissent discouraged

  • training practices that gradually indoctrinate members

29
New cards

Misconceptions of cults

  • Cults are easy to identify and define

  • Most cults are dangerous to others

    • most peaceful to others, even if harmful to members

  • Most people in cults are mentally ill (FAE)

    • 33% (higher than normal), most cult leaders are mentally ill

  • Brainwashing is required (controversial)

30
New cards

Prosocial behavior

Voluntary behavior for the benefit of others (e.g. friends, family, strangers or enemies)

Assume altruistic (unselfish concern) = prosocial

Prosocial behaviors are associated w/higher psychological + physical well-being in the helper

  • feels good to be good

31
New cards

What about punishment?

Just punishments can also be regarded as prosocial

  • discourage bad behavior, benefits group

  • educate transgressor

  • costly punishments (punisher pays a cost to deliver punishment) percieved as more legitimate

.

Controversial idea

  • punishment may not be based on universal principles; could simply be defensive response to your community being attacked

32
New cards

Predicting prosociality

  • Mood (esp. good moods)

  • Timing (when not rushed)

  • Potential for escape (likely to help if we can’t leave)

  • Background (e.g. doctor, nurse…)

  • Trait extroversion and empathy

  • Characteristics of the person in need (matching)

  • Egotistic reasons (relieving personal distress, joy of others we’ve helped, image of being a “better person”)

33
New cards

Bystander effect

Reduced likelihood to assist others when in groups

Many explanations

  • pluralistic ignorance (maybe its not really a problem)

  • diffusion of responsibility (someone else will do it)

  • cost of intervention, physical or psychological (feelings of judgement/vulnerability)

Among the strongest and most replicable effects

34
New cards

Aggression

Behavior intended to harm others, either verbally or physically

.

Most real-world studies are observational

.

Most laboratory studies use different measures (i.e. a test), do not resemble aggression in real world (e.g. assault)

  • unethical otherwise

.

Degree and severity affected by many factors

35
New cards

Aggression is more likely if…

  • Male, especially for direct aggression (w/confrontation)

  • Provocation by the individual (specific)

  • Overall frustration (non-specific)

  • Physiological arousal (w/provocation + frustration)

  • Reinforced by media (e.g. television, video games) and cues (e.g. guns)

  • Alcohol and temperature

36
New cards

Aggression and Temperature

Relationship holds in many countries and for many types of aggression, including severe (assaults) and mild acts (beanballs in baseball — throwing ball at batters face)

37
New cards

Heuristics

An approach to decision-making, problem-solving or discovery

We are faced with many problems, must make many important decisions quickly

Heuristics are useful

  • can be executed quickly, dont require lots of information

  • but, arent always accurate

38
New cards
<p>Heuristics examples</p>

Heuristics examples

Availability heuristic — what kind of info used to make a decision?

  • recent

  • frequent

  • extreme

  • vivid

  • negative

39
New cards

Representativeness Heuristic

Our tendency to organize information based on similarity of that information to already established categories

  • can be useful to extent (sorting objects)

  • applied to people can be problematic

40
New cards

Representativeness Heuristic — example

knowt flashcard image
41
New cards

Stereotyping

  • Can lead to prejudicial and discriminatory behavior

  • All have some risk for stereotyping

  • All benefit from experience, can affect thoughts, feelings and behaviors

  • If aware of a stereotype, can change behavior.

    • however, not always aware of the stereotypes

42
New cards

Implicit discrimination

Driven by associations of which individual is unaware (implicit associations)

Learned associations may influence unconscious processing and drive decision-making

One measure — implicit associations test (IAT)

  • many variations, critical is measurement of response time

43
New cards

implicit associations test — IAT

Subjects shown word or image — categorize it into one of two groups by hitting a key (“E” or “I”)

  • response time and keystroke logged

  • info comfortable with tends to be delivered quickly

  • differences in response time may reflect implicit associations (which could be biases)

44
New cards

Criticism of the IAT

Test-retest reliability concerns

Correlation to discriminatory behavior unclear

However, it has been argued that

  • weak effects become important on the societal level

  • IAT could be combined with other tests

Population scores change over time

45
New cards

Group biases

Biases emerge even if the groups involved are relatively new and based on arbitrary criteria

  • dot counting (Tajfel’s minimal group paradigm)

  • eye color (elliot’s original classroom study)

  • ingroup vs outgroup

.

Can be counteracted partially

  • Forced cooperation (e.g. Robber’s cave study)

  • Increased contact (e.g. Jigsaw Classrooms), provided proper context

46
New cards

Stereotype Threat

Stereotypes might not just affect judgment of others, but our own behavior

  • Stereotype threat fear of fulfilling a stereotype in a task negatively affects performance of that task

  • Meta-analysis suggest effect smaller than expected

47
New cards

Attributions

In theory, outcome of any event in a person’s life is due to the interaction of two factors: their traits and their environment

.

In dispositional attribution, outcome explained by trait

  • bad grades due to poor work ethic and low intelligence

.

In situational attribution, outcome explained by environment

  • bad grades because tragedy happened

48
New cards

Fundamental attribution error

When evaluating others, we consistently overestimate the role of dispositional factors

  • one of the most relevant and consistent findings in the field

49
New cards

Famous FAE experiment

  • Subjects randomly assigned to debate pro- and anti-Castro positions

  • Afterwards, each debater submitted a rating of other debater’s beliefs

  • Even though the participants knew speech assignment was random, they assumed the debaters agreed with the ideas that they presented

50
New cards

On FAE

  • Major reason for not including situational factors in evaluation of others is that we are unaware of them

  • Relavent to our view of world history: often fail to consider the unique situational factors that world leaders had at time of decision making

  • Bias may be lower in collectivist and greater in individualistic

51
New cards

Defensive Attributions

We particularly overemphasize dispositional factors when we succeed and overemphasize situational factors we fail (self-serving bias)

  • common in individualistic cultures (Western) where there is emphasis on achievements

  • self-serving biases might negatively affect performance (dont make right adjustments)

52
New cards

General criteria for a disorder

Statistical rarity

  • uncommon

.

Subjective distress

  • low quality of life, poor mental well-being

.

Impairment

  • cognition, emotional regulation, attention

.

Biological dysfunction

  • significant abnormalities in nervous system

.

Significant exceptions can exist, role of context

53
New cards

“Types” of Disorders

  • Cluster structure

  • Descriptive, not mechanistic

  • Not strongly supported

54
New cards

Major perspectives on Disorders – 1

A disorder (e.g. schizophrenia) is an invented classification, may not perfectly capture everything

.

We group things (human categories), but our groups may not reflect those naturally exist (natural kinds)

.

Disorders are likely heterogenous

  • many subtypes, with variability in causes, features, outsomes, treatment responses, etc

55
New cards

Major perspectives on Disorders – 2

Disease model

  • something biological “causes” disorder, causing symptoms

  • single symptom can be a suitable measurement

  • severity of symptoms ~ severity of disorder

.

Useful but not perfect

  • symptoms variable in number, frequency, and intensity

  • “cause” unclear

56
New cards

Major perspectives on Disorders – 3

Network model

  • disorder is an interaction between symptoms

  • multiple symptoms must be studied

  • related: dynamical systems approach

.

New, needs refinement

  • data collection + analysis more complex

  • validity less clear

57
New cards

Misconceptions on Models

  1. Diagnosis is categorizing people (pigeon-holing)

  • person does not lose individuality with diagnosis

.

  1. Diagnoses are unreliable (experts never agree)

  • clinicians agree on many disorders, some are hard to diagnose

.

  1. Diagnoses are invalid

  • diagnoses can predict outcomes

.

  1. Diagnoses negatively impact a person’s life

  • in right context (supportive environment), diagnosis helps

58
New cards

Diagnosing Disorders

Requires interview assessment from professional using standardized, evidence-based guidelines

  • diagnostic criteria from the DSM could guide diagnosis

.

Biological tests may be done to exclude other problems (e.g. thyroid)

.

Biological tests do not usually inform diagnosis

  • neuroimaging (brain structure/function) not typically used

  • view of disorders as “brain disorders” is impractical

  • genetic testing rarely used, but family history can be

59
New cards

DSM-5 Features

~300+ disorders

Biopsychosocial approach

  • biological, psychological (thinking patterns), societal factors (culture)

60
New cards

DSM-5 Criticisms

  • Not all disorders meet validity criteria

  • Vagueness may lead to “pathologization” of normal behavior

  • Categorical (binary; either/or) rather than dimensional

  • Comorbidities (share root cause)

  • Concerns about lack of transparency, pace of preparation, conflicts of interest

61
New cards

Anxiety disorders

  1. Generalized Anxiety Disorder (GAD)

  2. Panic Disorder

  3. Phobias

  • ~4% of people may suffer (mostly phobias)

  • related but now independent: obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD)

62
New cards

1 – GAD Generalized Anxiety Disorder

  • Exaggerated worry/tension in day-to-day situations

  • May later lead to emergence of other disorders (network model)

  • More common in females than males

63
New cards

2 – Panic Disorders

Characterized by recurrent episodes of intensive fear (w/sweating, dizziness, light headaches, breathing difficulty, heart irregularities)

  • while many report single panic attack, in disorder the attacks are repeated and unexpected

  • emerges eary in adulthood

64
New cards

3 – Phobias

Most common of all anxiety disorders

  • intense, irrational fear of specific thing

  • may be outgrowth of panic disorder

  • agoraphobia (fear of marketplaces or crowded environments)

65
New cards

4 – OCD

Obsessions are persistent thoughts that are unwanted and/or cause stress

  • centered topics: sex, contamination, aggression, religion

.

Compulsions are repetitive behaviours undertaken to reduce distress and relieve shame/guilt

  • washing hands

  • re-reading sentences

66
New cards

What causes anxiety? Learning/Behaviorist perspective

Classical conditioning mechanisms

  • CS/UCS —→ CS signals UCS —→ CS leads to CR

  • cars + accident, car signals accident, car causes fear

.

Operant conditioning mechanisms

  • If cars (S-) give anxiety, may avoid (R)

  • avoiding = less anxiety, motivated to continue avoiding (increase in R)

  • maintenance of fear through negative reinforcement

67
New cards

What causes anxiety? Other factors

  • Possible role of genetics — show some heritability

  • Rate of anxiety (& depression) rising — environment changes likely factor

  • Nature of envrionmental influence debated — digital tech, free play in childhood, occupation, relationships

68
New cards

What is depression?

  • Loss of interest or pleasure in activities normally enjoyed (e.g. anhedonia)

  • Decreased energy (e.g. fatigue)

  • Feelings of guilt or low self-worth

  • Disturbed sleep, appetite and activity

  • Inability to concentrate

  • Thoughts of suicide

Product of life

69
New cards

Global burden of depression

~5% of population 1, higher rates in young cohorts

  • Associated with lower quality of life, suicide, other poor outcomes, significant economic cost

  • Leading cause of disability worldwide

  • Good news: normally treatable (70 – 80% of cases)

70
New cards

Types of Depression

Unipolar depressive disorder

  • Major Depressive Disorder (MDD; chronic)

  • Major Depressive Episodes (MDE; acute but often recurrent)

Post-partum depression

Dysthymia

Seasonal affective disorder

.

Depressive episodes also occur in bipolar disorder, but is considered separately

71
New cards

Epidemiology of Depression

1. Gender

2. Community

3. Socioeconomic status

4. Occupation

5. Life history

72
New cards

Epid of Depression — 1 - gender

More common in women (~2x) though the severity does not differ

  • Reasons for disparity are complex

.

Multiple factors possible

  • Hormones (post partum)

  • Low in males due to stigma

  • High in females due to social pressures (family roles, unpaid labor, societal expectations)

73
New cards

Epid of Depression — 2 – Community

Burden of depression may be higher in Western, developed countries

.

Many potential reasons for this disparity (not exclusive):

  • more awareness, less stigma

  • better diagnostic criteria, health care access

  • beliefs about efficacy of emotional regulation

  • valuation of happiness in western cultures

  • description of disorder within the culture

74
New cards

Epid of Depression — 3 – SES

Low SES (i.e. low income) increases risk

In Eastern + Western communities, even with control for other variables

Main argument that low income leads to depression

  • relationship between income + well-being complex

Low income may be associated with increased risk for many reasons (e.g. lack of insurance, health care…)

.

Burden may be higher in developed countries with stronger economies, but risk is lower in people of higher SES

75
New cards

Epid of Depression — 4 – Occupation

If you don’t have a job, the risk is also higher (nearly x2)

76
New cards

Why does the risk vary by job?

Social interaction plays a role but it is complex

  • Difficult (service) and rare (trucking/transport) interactions both a issue

.

Stress level (high increases risk)

.

Physical activity (low increases risk)

.

Jobs offer varying degrees of validation (skills), feelings of meaning/status/acceptance, income and access to vital services

77
New cards

Epid of Depression — 5 – Life history

Risk for mental disorders increases with stress frequency

  • life events

78
New cards

Theoretical models

Behavioral models proposed by Lewinsohn

  • Low rate of reinforcement: try many things w/no success

  • Learned helplessness is a related concept (Seligman)

.

Interpersonal model proposed by Coyne

  • Look to others for assurance > others respond negatively (hostility + rejection) > increasing need for reassurance

.

Cognitive model popularized by Beck

  • Cognitive distortions affect ability to acknowledge reality or interpret it; best describes serious depression

79
New cards

Biological Features of Depression

Hippocampus, orbitofrontal cortex, anterior cingulate cortex smaller

Substance Use Disorder (formerly addiction) — What is addiction?

Complex brain disease, there is compulsive engagement in behavior despite knowledge of harmful consequences

.

The term “brain disease” suggests considering the brain is critical

  • Matters for treatment, other competing perspectives exist (e.g. choice)

.

”Behavior” can mean many things (e.g. substance use, gambling, sex or video games)

.

“harmful” is itself a poorly defined term

81
New cards

Risk factors for SUD

  • Stability of home environment

  • Early use + peer groups

  • Education

  • Employment

  • Genetics

  • Gender

    • Usage/dependence rates higher in men for many drugs, overdose rates higher in women for some drugs

  • Mental health status

    • Co-morbidities frequent

82
New cards

Comorbidities

83
New cards

Treating SUD

View of SUD as a “disease of the brain” or a “choice” has implications for treatment/quality of life

  • beliefs vary by country

.

Hybrid views favoured, extreme views not

  • radical version of choice: concern over aggressive policies, stigma

  • radical disease: concern treatments may be less effective

.

Prognosis good with treatment; majority recover

  • psychological and pharmacological treatments

84
New cards

Bipolar Disorder

Extreme swings in mood, including episodes of elevated mood (e.g. mania)

During periods of elevated mood, feels extremely energetic, happy and/or irritable

  • reduced need for sleep

  • reckless decision-making

85
New cards

Bipolar Disorder

  • ~1% of the global population

  • One of the most costly disorders worldwide (top 10)

  • Risk of absenteeism, suicide and self-harm is high

  • Related to several other traits (particularly creativity), over-represented in certain populations (creative professionals/artists)

86
New cards

Personality disorders

  • Inflexible patterns of behavior — lead to distress

  • Emerge in adolescence, around same time as personality traits

  • Difficult to reliably diagnose; less researched than other conditions

  • Category includes borderline personality disorder, narcissistic personality disorder and anti-social personality disorder

87
New cards

Autism Spectrum Disorder — Symptoms

Poor social interaction

  • Fails to respond to name, poor eye contact, resists cuddling, prefers being alone

  • May not recognize/respond to social cues

.

Repetitive behaviors/Difficulty switching behaviors

  • Arranging objects, making sounds, hand flapping, head rolling and body rocking

  • Special interests

.

Slow language development

  • Starts later than age of 2 (may remain non-verbal), repetition of words/phrases (echolalia), abnormal tone/rhythm

The Spectrum

Exceptional cognitive abilities are rare (~10%)

.

Strong genetic basis (twin studies: h2 = 0.6 to 0.7)

.
