Defining Social Psychology: History and Principles
1.1 Defining Social Psychology: History and Principles
🧭 Overview
🧠 One-sentence thesis
Social psychology is the scientific study of how our feelings, thoughts, and behaviors are profoundly shaped by both our individual characteristics and—often more powerfully—by the social situations and people around us.
📌 Key points (3–5)
- What social psychology studies: how we feel, think, and behave toward others, and how others influence us in return.
- The person-situation interaction: behavior results from both individual characteristics and social context, with the situation often being the stronger influence.
- Two fundamental human motivations: self-concern (protecting ourselves and those close to us) and other-concern (connecting with and helping others).
- Common confusion: we often wrongly assume people act purely from personal traits, underestimating how much the social situation drives behavior.
- Social norms and culture: shared ways of thinking and behaving vary across cultures (e.g., individualism in the West vs. collectivism in East Asia) and powerfully guide our actions.
📜 Historical development of the field
📜 Early foundations (before 1900–1950s)
- The first social psychology experiments on group behavior appeared before 1900.
- The first textbooks were published in 1908.
- Kurt Lewin (known as "the father of social psychology") and Leon Festinger refined experimental methods in the 1940s–1950s, establishing social psychology as a rigorous science.
- Lewin emphasized dynamic interactions among people; Festinger stressed systematic measurement and laboratory experiments (sometimes requiring deception).
📜 Post-WWII expansion (1950s–1970s)
- Researchers sought to understand how Adolf Hitler produced extreme obedience and horrendous behaviors.
- Key studies:
- Conformity: Muzafir Sherif (1936) and Solomon Asch (1952) showed the power of group pressure.
- Obedience: Stanley Milgram (1974) demonstrated that authority figures could lead ordinary people to inflict severe harm.
- Prison study: Philip Zimbardo found that role-playing guards and prisoners became so violent the study had to end early.
- Other topics emerged: helping behavior (Darley & Latané), aggression (Berkowitz), group decision-making (Janis), and intergroup relations (Allport, Sherif).
- Social psychologists contributed expert testimony in landmark cases like Brown v. Board of Education (1954).
📜 Cognitive turn and modern expansion (1970s–present)
- The field became more cognitive in the 1970s–1980s, studying how people process social information, form attitudes, and make judgments.
- Leon Festinger's cognitive dissonance theory became a foundational model.
- Researchers (Eagly, Fiske, Higgins, Nisbett, Ross, Taylor, and others) explored social cognition: how knowledge about the social world develops and influences memory, attitudes, and judgment.
- Research revealed that human decision-making is often flawed due to cognitive and motivational biases.
- In the 21st century, the field expanded into health, evolutionary psychology, culture, and social neuroscience (how social behavior and brain activity influence each other).
🧩 The person-situation interaction
🧩 Lewin's fundamental equation
Behavior = f(person, social situation)
- This equation means: a person's behavior at any moment depends on both their individual characteristics and the influence of the social situation.
- Social psychologists emphasize that the social situation is often a stronger determinant of behavior than personality.
- Example: In analyzing events like the Holocaust, social psychologists focus more on situational factors (strong leaders, group pressure) than on the perpetrators' individual traits.
🧩 Why we underestimate the situation
- We often wrongly assume that people act entirely on their own accord, without external influences.
- It is tempting to think that people who commit extreme acts (terrorists, cult members) are inherently unusual or extreme.
- Research shows these behaviors are caused more by the social situation than by individual characteristics.
- Don't confuse: attributing behavior to personality alone vs. recognizing the powerful role of context.
🧩 What "person" means
- Person refers to individual characteristics: personality traits, desires, motivations, emotions.
- These characteristics exist because of evolutionary adaptation: genetic traits that helped our ancestors survive and reproduce.
- Humans are born with social skills (recognizing faces, learning language, forming friendships) that were selected through evolution.
- Our large brains provide us with exceptional social intelligence.
🎯 Two fundamental human motivations
🎯 Self-concern: protecting the self and kin
Self-concern: the motivation to protect and enhance our own life and the lives of people psychologically close to us.
- The most basic tendency of all living organisms is to survive: find food, water, shelter, and avoid danger.
- We also protect and enhance our relatives (those genetically related to us).
- Kin selection: strategies that favor the reproductive success of relatives, even at a cost to the individual, because they increase the survival of the group as a whole.
- We extend this care to our ingroup: people we view as similar and important, even if not genetically related (e.g., close friends).
- Example: Helping friends move furniture, even when you'd prefer to study or relax, because you feel close to them.
🎯 Other-concern: connecting and cooperating
Other-concern: the motivation to affiliate with, accept, and be accepted by others.
- Humans desire to connect with and be accepted by people more generally, not just close kin or ingroup members.
- We live, work, worship, and play together in communities and groups.
- Affiliating with others (even strangers) helps us meet fundamental goals, like finding romantic partners and accessing opportunities we couldn't have alone.
- We engage in mutual cooperation: trading goods and services, which benefits everyone.
- Humans behave morally toward others: we understand it is wrong to harm people without strong reason, and we display compassion and altruism.
- Negative behaviors (bullying, cheating, stealing, aggression) are unusual and socially disapproved—hostility and violence are the exception, not the rule.
🎯 When motivations conflict
- Sometimes self-concern and other-concern align: falling in love benefits both ourselves (we feel good) and the other person.
- Other times they conflict: Example: seeing someone threatened with a knife—do you intervene (other-concern) or protect yourself from danger (self-concern)?
- We must decide which goal to prioritize.
🌍 Social influence and social norms
🌍 What social influence is
Social influence: the process through which other people change our thoughts, feelings, and behaviors, and through which we change theirs.
- Social influence can be passive: we adopt beliefs and behaviors of those around us without awareness (e.g., a child adopts parents' values; someone starts liking jazz because a roommate plays it).
- Social influence can be active: deliberate attempts to change beliefs or behaviors (e.g., jury members persuading a dissenter; celebrity endorsements; cult leaders directing followers).
🌍 Social norms
Social norms: the ways of thinking, feeling, or behaving that are shared by group members and perceived by them as appropriate.
- Norms include customs, traditions, standards, rules, and general values.
- We learn what people actually do ("Americans eat scrambled eggs in the morning") and what we should or shouldn't do ("do unto others as you would have them do unto you"; "do not make racist jokes").
- Norms guide almost every social behavior and have a big influence on our actions.
- Even when alone (e.g., stopping at a stop sign on a deserted road late at night), we are influenced by internalized norms—we carry our social experiences with us.
🌍 The power of the social situation
- Our relationships with others are among the things we value most.
- We depend on others to help us meet goals (class projects, volunteer work, jury duty).
- We are influenced not only by people physically present but also by those in our thoughts and memories.
- Key principle: Although individual characteristics matter, the social situation is often a stronger determinant of behavior than personality.
🌏 Cultural differences in social norms
🌏 What culture is
Culture: a group of people, normally living within a given geographical region, who share a common set of social norms, including religious and family values and moral beliefs.
- Culture affects our thoughts, feelings, and behavior through teaching, imitation, and other forms of social transmission.
- Our culture defines our lives as much as our evolutionary experience does.
🌏 Individualism vs. collectivism
| Dimension | Western cultures (individualism) | East Asian cultures (collectivism) |
|---|---|---|
| Primary focus | Self-enhancement and independence | Harmonious relationships and interdependence |
| What children learn | Develop and value personal self; feel special; seek personal achievement | Focus on group togetherness, connectedness, duty to family |
| Self-description | "Do my own thing"; live independently; base happiness on personal achievements | Concerned about interests of others, close friends, colleagues |
| Source of happiness | Personal accomplishments | Connections with other people |
- Western cultures (U.S., Canada, Western Europe, Australia, New Zealand): norms emphasize individualism—self-enhancement and independence.
- East Asian cultures (China, Japan, Taiwan, Korea, India, Southeast Asia): norms emphasize collectivism (interdependence)—being fundamentally connected with others.
- Example: East Asians are more likely to experience happiness from connections with others; Westerners from personal accomplishments.
🌏 Other cultural variations
- Time orientation: Some cultures are strict about schedules; others are more flexible.
- Pace of life: Fastest in Western countries (and Japan); slowest in economically undeveloped countries (measured by walking speed and postal clerk speed).
- Social norms vs. individuality: Cultures differ in how much people are bound by social norms vs. free to express individuality.
- Personal space and communication styles: Cultures vary in how close people stand when talking and how they communicate.
🌏 Why cultural awareness matters
- People from different cultural backgrounds increasingly interact due to travel, immigration, and the Internet.
- In Canada, for example, roughly 21% of the population is foreign-born (highest among G8 countries).
- By 2031, visible minorities are projected to make up 63% of Toronto's population and 59% of Vancouver's.
- These changes create potential for greater understanding and productive interaction, but also potential for social conflict.
- Being aware of cultural differences is an important part of understanding social psychology.
💪 The importance of social connections
💪 Social support and mental health
- People with adequate social support (a network of others they can rely on) report being happier and have fewer psychological problems (eating disorders, mental illness).
- They are less depressed overall, recover faster from negative events, and are less likely to commit suicide.
- Married people report being happier than unmarried people; a happy marriage is an excellent form of social support.
- Effective psychotherapy helps people generate better social support networks because such relationships have positive effects on mental health.
💪 Social support and physical health
- People with adequate social support are more physically healthy.
- They have fewer diseases (tuberculosis, heart attacks, cancer), live longer, have lower blood pressure, and have fewer deaths at all ages.
- Athletes with higher social support are less likely to be injured and recover more quickly from injuries.
- These differences appear to be due to positive effects of social support on physiological functioning, including the immune system.
💪 The pain of exclusion and ostracism
- The opposite of social support is feeling excluded or ostracized.
- The pain of rejection may linger even longer than physical pain.
- People rate memories of social pain (e.g., betrayal) as more intense than memories of intense physical pain.
- When threatened with exclusion, people express greater interest in making new friends, increase their desire to cooperate, form more positive first impressions, and become better at distinguishing real from fake smiles.
- Ostracism as a tool: Withholding social communication (e.g., the "silent treatment") is a powerful weapon for punishing individuals and forcing behavior change.
- Ostracism is used in various contexts: Amish religion (Meidung), parent-child relationships, Internet games and chat rooms.
- Ostracized individuals report feeling alone, frustrated, sad, unworthy, and having lower self-esteem.
- Ostracism is particularly painful for adolescents.
💪 Practical takeaway
- One of the most important things you can do for yourself is develop a stable support network.
- Reaching out to others benefits both them (you are in their network) and you (substantial benefits for mental and physical health).
