SPSS201 Social Psychology Exam Notes: Nelson Mandela University (NMU) Study Guide

Social psychology examines how thoughts, feelings, and behaviour are shaped by the actual, imagined, or implied presence of others. For SPSS201 Social Psychology at Nelson Mandela University (NMU), the key theories usually tested are not just definitions to memorize, but frameworks for explaining everyday social life: attitudes, prejudice, helping, conformity, aggression, interpersonal attraction, and group behaviour. Strong exam performance depends on understanding each theory’s core assumptions, supporting research, limitations, and how theories compare with one another in real-world contexts.

1. What Social Psychology Is and Why Theory Matters in SPSS201

Social psychology sits at the intersection of the individual and the social world. It asks questions that seem simple but become complex very quickly: Why do people obey authority? Why do they conform even when they know a group is wrong? Why do stereotypes persist even when people claim to value fairness? Why do some people help strangers while others walk past? Theories in social psychology are the tools used to answer these questions in a structured way. In an exam, marks are often awarded not only for knowing the theory, but for showing how it explains social behaviour better than an alternative explanation.

At NMU level, the strongest answers usually show three things:

1. A clear definition of the theory
2. An explanation of the processes involved
3. Evidence, application, and evaluation

A theory is more than a summary of what happens. It is a model of why it happens. For example, saying “people conform because they want to fit in” is a basic statement. Saying “people conform because normative social influence motivates acceptance and avoidance of rejection, while informational social influence motivates reliance on others as a source of reality when situations are ambiguous” is a theoretical explanation. The second answer is stronger because it identifies the underlying psychological mechanisms.

Core Assumptions of Social Psychology

Several assumptions appear repeatedly across social psychology theories:

• Behaviour is shaped by context. People may act differently in different groups, cultures, or situations.
• Social influence is powerful. Others influence us directly and indirectly through norms, expectations, and comparison.
• Cognition mediates behaviour. People do not simply respond to situations; they interpret them.
• Perception is selective. We do not process all social information equally.
• Individuals and groups interact dynamically. Group behaviour can be understood only by considering both the person and the social setting.

These assumptions matter because many theories differ in emphasis. Some stress social learning, others stress cognitive interpretation, and others stress group identity or motivational needs. In exams, distinguishing among these emphases is often the key to a high score.

Why Theories Are Examinable

Examiners often assess whether students can:

• compare competing theories,
• identify where a theory applies,
• explain why a theory might fail,
• and use a theory to interpret a real social event.

For example, if asked why prejudice exists, a weak answer may simply say “people are taught stereotypes.” A stronger answer might compare social learning theory and realistic conflict theory, explaining that prejudice can come from reinforcement and modelling, but also from competition over resources and intergroup threat. That type of comparative reasoning shows real understanding.

The Role of Evidence

Social psychology theories are supported by classic studies. Research design is important because many theories were developed through laboratory experiments, field studies, or naturalistic observation. A student should know that classic studies are not just historical facts; they demonstrate how the theory works.

For example:

• Asch’s conformity research shows that group pressure can override private judgment.
• Milgram’s obedience studies show the power of authority.
• Festinger’s cognitive dissonance theory explains why people change attitudes when behaviour and beliefs conflict.
• Tajfel’s social identity theory explains why group membership can produce bias even without competition.

Understanding the studies gives the theory empirical support and helps in evaluation. Yet exam answers should also mention that classic studies often involved narrow samples, artificial tasks, and ethical concerns. These limitations are not peripheral—they are central to evaluating the theory’s generalisability.

A Useful Way to Study Theories

A practical study method is to learn each theory under the same headings:

• Definition
• Main assumptions
• Key concepts
• Classic study
• Strengths
• Limitations
• Application to everyday life
• Comparison with another theory

This structure helps produce complete exam answers. It also prevents the common problem of describing studies without connecting them back to the broader theory.

The Broad Landscape of SPSS201 Theories

The key theories in social psychology typically fall into the following families:

• Learning-based theories: social learning theory, reinforcement, modelling
• Cognitive theories: attribution theory, cognitive dissonance, schema theory
• Intergroup theories: social identity theory, realistic conflict theory
• Influence theories: conformity, obedience, compliance
• Attitude theories: persuasion models, balance theory, consistency theory
• Prosocial and antisocial behaviour theories: bystander intervention, aggression theories

Although these areas seem separate, they overlap constantly. For example, prejudice can involve learning, cognition, identity, and social norms at the same time. A strong student does not treat theories as isolated islands. Instead, the student sees how they interlock and where they offer competing explanations.

2. Social Influence Theories: Conformity, Compliance, and Obedience

Social influence theories explain how people adjust their behaviour in response to others. These theories are among the most important in social psychology because they demonstrate that individuals are not always independent decision-makers. Sometimes they follow group norms, comply with requests, or obey authority even when doing so conflicts with personal judgment.

Conformity

Conformity is a change in behaviour or belief as a result of real or imagined group pressure. It does not always mean weakness or irrationality. In many cases, conformity is adaptive because social life requires coordination. People conform to classroom rules, workplace dress codes, traffic laws, and community norms in order to function smoothly.

Two main types of social influence explain conformity:

Normative Social Influence

This occurs when people conform to be liked, accepted, or not rejected. The behaviour may not reflect private belief. A student may laugh at a joke in a group even if they do not find it funny, simply to avoid standing out.

Informational Social Influence

This occurs when people conform because they believe others have more accurate information. In ambiguous situations, people use the group as a source of evidence. For example, if people in a lecture room suddenly move toward a different door, a newcomer may follow because they assume there is a reason.

A useful exam distinction is this: normative influence is about social approval, while informational influence is about social reality.

Asch’s Conformity Research

Solomon Asch’s line-judgment experiments are classic because they demonstrate how strong group pressure can be. Participants were asked to identify which comparison line matched a standard line. Confederates intentionally gave wrong answers. Many participants conformed at least some of the time, even though the correct answer was obvious.

The significance of Asch’s findings is not that people always conform, but that even in clear situations, group pressure can distort public responses. This shows the power of unanimity, group size, and the fear of being deviant. In exam terms, Asch is essential evidence for normative social influence.

Factors Affecting Conformity

Several variables influence conformity rates:

• Group unanimity: conformity increases when the group agrees
• Task difficulty: ambiguity raises informational influence
• Group size: conformity tends to rise with more confederates, though only up to a point
• Public response: people conform more when answers are visible to others
• Cultural context: collectivist settings may encourage more group harmony than highly individualistic settings

A stronger answer will not just mention these variables but explain why they matter. For instance, unanimity matters because a single dissenter can restore confidence in independent judgment.

Compliance

Compliance refers to changing behaviour in response to a direct request, without necessarily changing private belief. It is less forceful than obedience and often occurs in everyday settings such as sales, fundraising, or peer requests.

Useful compliance techniques include:

• Foot-in-the-door: a small request is followed by a larger one
• Door-in-the-face: a large request is followed by a smaller one
• Lowballing: an attractive offer is made, then hidden costs are added
• That’s-not-all: an offer is improved before a decision is made

These techniques work because they manipulate consistency, reciprocity, obligation, and perceived commitment. For example, once a person agrees to a small request, they may feel pressure to remain consistent with that earlier decision.

Obedience

Obedience is compliance with direct orders from an authority figure. It is especially important because it can lead to harmful actions carried out by ordinary people in structured systems. Obedience shows how power, hierarchy, and legitimacy shape behaviour.

Milgram’s obedience studies are central here. Participants believed they were delivering increasingly severe electric shocks to a learner whenever incorrect answers were given. Many continued obeying the experimenter even when they were distressed. The key insight is not that participants were cruel by nature, but that the situation created pressure through authority legitimacy, gradual escalation, and diffusion of responsibility.

Why People Obey

People obey because of several interacting factors:

• Legitimacy of authority: authorities are seen as entitled to give orders
• Gradual commitment: small initial steps make later ones easier
• Agentic shift: individuals feel like agents executing another’s wishes rather than independent moral actors
• Responsibility displacement: blame is psychologically shifted to the authority
• Socialisation into obedience: many societies reward respect for hierarchy

These mechanisms help explain why obedience can occur in institutions such as schools, armies, hospitals, and workplaces.

Evaluation of Social Influence Theories

These theories are powerful because they explain ordinary behaviour in structured settings. Yet they also have limitations.

Strengths

• Supported by well-known experiments
• Useful in explaining real-world group dynamics
• Applicable to education, law, work, and public health

Limitations

• Classic studies may have low ecological validity
• Participants may respond differently across cultures and historical periods
• Some findings can be overgeneralised into “people are weak,” which is not the real conclusion
• Ethical concerns, especially in obedience research, are significant

A sophisticated exam answer should note that social influence theories do not claim people are mindless. Rather, they show that people often navigate competing pressures: wanting social approval, trying to be accurate, and respecting legitimate systems. The best answers acknowledge this complexity instead of reducing conformity or obedience to simple weakness.

3. Cognitive Theories: Attribution, Cognitive Dissonance, and Schemas

Cognitive theories explain social behaviour by focusing on how people interpret information, make judgments, and maintain internal consistency. Rather than asking only what others do to us, cognitive theories ask how we process the social world. This is crucial because people do not react directly to events; they react to the meanings they assign to those events.

Attribution Theory

Attribution theory examines how people explain the causes of behaviour. When someone behaves in a particular way, observers usually ask: Is this due to personality, or is it due to the situation? These explanations are called attributions.

Internal and External Attribution

• Internal attribution: behaviour is caused by personal traits, motives, or intentions
• External attribution: behaviour is caused by environmental pressures or situational factors

For example, if a student arrives late to class, one observer might say the student is lazy (internal attribution), while another might say transport was delayed (external attribution).

Correspondence Bias and the Fundamental Attribution Error

A major finding in attribution research is that people often overestimate internal causes and underestimate situational ones. This tendency is known as the fundamental attribution error or correspondence bias in many introductory texts.

This matters because social judgement is often unfair. When someone cuts into traffic, we may assume they are rude or careless rather than considering time pressure, emergency, or uncertainty. The theory explains why social perception often becomes moralised too quickly.

Heider, Kelley, and Consensus Information

A useful way to understand attribution is through Kelley’s covariation principle, which suggests that people consider three kinds of information:

• Consistency: does the person behave this way across time?
• Distinctiveness: does the person behave this way in only this situation?
• Consensus: do other people behave similarly in the same situation?

If a student is always late, late for all classes, and others are also late because of transport strikes, external attribution becomes more plausible. If a student is only late in one class and others are punctual, internal attribution becomes more likely.

This framework is useful in exam answers because it shows attribution as structured reasoning rather than random guesswork.

Attribution Biases and Social Consequences

Attribution biases influence stereotypes, conflict, and prejudice. For example, in intergroup conflict people often explain their own group’s failures through external causes while explaining the other group’s failures through internal defects. This protects self-esteem and group identity but distorts reality.

Examples include:

• blaming unemployed people for laziness while ignoring economic conditions,
• treating low academic performance as lack of ability rather than poor schooling,
• interpreting another culture’s behaviour through one’s own values.

These patterns show that attribution is not neutral. It is deeply tied to power, identity, and social values.

Cognitive Dissonance Theory

Leon Festinger’s cognitive dissonance theory explains the discomfort people feel when their attitudes and behaviours conflict. Humans prefer internal consistency, so when inconsistency arises, they are motivated to reduce it.

A classic example is a person who believes smoking is dangerous but continues smoking. The mismatch creates dissonance. The person may reduce discomfort by:

• changing behaviour and quitting,
• changing beliefs and downplaying the danger,
• adding justifications such as “everyone dies of something,”
• avoiding information that increases discomfort.

The key point is that dissonance is a motivational state. People do not simply hold contradictory ideas passively; they are driven to restore coherence.

Why Dissonance Matters

Dissonance theory explains many real-world phenomena:

• justifying effort after joining a difficult club,
• rationalising costly purchases,
• defending public commitments,
• shifting attitudes after difficult decisions.

For example, after choosing one of two similar job offers, a person may rate the chosen job more positively and the rejected one more negatively. This is known as post-decisional dissonance reduction. The theory explains why people often become more convinced of a choice after making it.

Schemas and Social Perception

Schemas are mental structures that organise knowledge about people, groups, roles, and events. They help us process information quickly, but they can also distort perception.

Important schema-related concepts include:

• Person schemas: knowledge about individuals or personality types
• Role schemas: expectations about people in social roles
• Event schemas: expectations about sequences of events, such as a restaurant script
• Self-schemas: beliefs about one’s own traits and identity

Schemas are efficient, but they can create bias. If someone has a schema that “professors are strict,” they may interpret neutral behaviour as coldness. Schemas also affect memory because people tend to remember information consistent with existing expectations.

Evaluation of Cognitive Theories

Strengths

• Explain why people interpret the same event differently
• Useful for understanding prejudice, decision-making, and attitude change
• Supported by extensive experimental research

Limitations

• Can underplay emotion and social power
• Sometimes treats people as overly rational information processors
• Does not always explain why certain beliefs are more resistant than others
• Cultural factors may shape attribution patterns and self-consistency motives

A strong exam answer should state that cognitive theories do not deny social influence. Instead, they show that social influence works partly because people interpret events through mental frameworks. This makes cognition a bridge between the social situation and behaviour.

4. Intergroup Theories: Social Identity, Self-Categorisation, and Intergroup Conflict

Intergroup theories explain how group membership shapes identity, perception, and bias. These theories are especially important in South African contexts because issues of race, class, language, gender, and historical inequality remain central to social life. In many social psychology courses, students are expected to connect theory to societal division, not just abstract laboratory findings.

Social Identity Theory

Henri Tajfel’s social identity theory argues that part of a person’s self-concept comes from membership in social groups. People do not only think “I am an individual”; they also think “I am a member of this group.” That group membership becomes emotionally meaningful.

The theory proposes three processes:

1. Social categorisation: people classify themselves and others into groups
2. Social identification: people adopt the identity of their in-group
3. Social comparison: people compare their group with out-groups to preserve positive distinctiveness

The desire for positive self-esteem motivates people to see their own group favorably. This can produce in-group favouritism even without direct conflict.

Tajfel’s Minimal Group Paradigm

The minimal group paradigm showed that even arbitrary group divisions can produce bias. Participants were assigned to groups on trivial grounds, such as preference for paintings or random allocation, and still distributed rewards in ways that favored their own group. This finding was powerful because it showed that discrimination does not require long-standing hostility or material competition. Group categorisation itself can be enough.

That insight is important in exams: intergroup bias can emerge very quickly, even when groups are artificial.

Self-Categorisation Theory

Self-categorisation theory develops social identity theory further by focusing on how people move between personal identity and social identity depending on context. In some situations, people think of themselves as unique individuals; in others, they see themselves as interchangeable group members.

This helps explain:

• why people behave more normatively in groups,
• why identity salience changes behaviour,
• why group norms become powerful when a category becomes important.

For example, a student may act as a unique individual in a one-to-one conversation, but as a member of “our class” during a group discussion with another class. The context changes which identity becomes salient.

In-Group Bias and Out-Group Discrimination

In-group bias means favouring one’s own group. Out-group discrimination means treating other groups less favorably. These do not always stem from hatred. Sometimes they arise from simple identity maintenance, norm reinforcement, or perceived competition.

Important points:

• Bias can be subtle and automatic
• People may genuinely believe they are fair while still showing in-group preference
• Bias can be intensified by threat, inequality, or competition
• Positive contact can reduce prejudice, but only under favourable conditions

Realistic Conflict Theory

Realistic conflict theory argues that intergroup hostility develops when groups compete over limited resources such as jobs, housing, land, or political power. Unlike social identity theory, which emphasizes categorisation and identity, realistic conflict theory focuses on material competition.

For example, when communities feel that access to employment or housing is scarce, frustration may be redirected toward out-groups. The result is blame, stereotyping, and hostility. This theory is useful because it explains prejudice in terms of structural conditions rather than only psychological bias.

Contact Hypothesis

The contact hypothesis suggests that under certain conditions, interaction between groups can reduce prejudice. However, contact is not automatically beneficial. It works best when:

• groups have equal status in the situation,
• they cooperate toward shared goals,
• the contact is supported by authorities,
• and there is opportunity for meaningful interaction.

This is an important evaluation point. Mere proximity does not guarantee understanding. Poor-quality contact can even increase hostility if it occurs under unequal or competitive conditions.

Evaluating Intergroup Theories

Strengths

• Explain why bias can occur even without overt competition
• Connect identity with emotion and behaviour
• Useful in diverse and divided societies
• Provide a basis for prejudice reduction strategies

Limitations

• Social identity theory can understate economic and political inequality
• Realistic conflict theory does not fully explain bias where no direct competition exists
• Laboratory minimal-group studies may oversimplify real social conflict
• Not all people respond to group membership in the same way

A strong answer compares these theories rather than treating them as rivals without connection. For example, social identity theory explains how bias becomes psychologically meaningful, while realistic conflict theory explains why it intensifies under material pressure. Together they provide a fuller picture than either one alone.

5. Attitudes, Persuasion, Prosocial Behaviour, and Aggression: Applying Theories in Exams

Many SPSS201 questions ask students to apply theory to attitudes and behaviour. These topics are often where theories come alive, because they affect advertising, politics, violence, helping, and everyday decision-making. A student who understands theory in this area can produce much stronger application answers than one who only memorizes definitions.

Attitudes and Attitude Change

An attitude is a relatively stable evaluation of an object, person, issue, or behaviour. Attitudes usually include three components:

• Cognitive: beliefs or thoughts
• Affective: feelings
• Behavioural: intentions or actions

For example, someone may believe smoking causes disease, feel disgust toward smoking, and avoid smokers. These three components often align, but not always. A person may oppose smoking in principle yet continue the habit, which is where dissonance becomes useful.

Persuasion Theories

Persuasion is the process of changing attitudes through communication. Key theories include:

• Elaboration Likelihood Model (ELM): persuasion occurs through a central route or peripheral route
• Cognitive response approaches: people respond to persuasive messages with their own thoughts
• Source-Message-Channel-Receiver models: persuasion depends on communicator, message quality, medium, and audience

The ELM is especially important. The central route involves careful consideration of arguments and leads to more durable change. The peripheral route relies on cues such as attractiveness, expertise, or emotional tone and often produces more temporary change.

For example:

• A student carefully reading evidence about vaccination uses the central route.
• A student buying a product because a celebrity endorsed it uses the peripheral route.

This theory is useful because it predicts when attitudes will be strong and lasting.

The Role of Fear Appeals and Emotion

Persuasion does not depend only on logic. Fear appeals, emotional framing, and social norms often shape attitudes. However, fear is effective only when people believe they can act to reduce the threat. If a message creates fear without offering efficacy, people may deny or avoid the message.

This explains why health campaigns often combine:

• threat information,
• clear behavioural advice,
• and a sense of achievable control.

Prosocial Behaviour and Helping

Prosocial behaviour includes actions intended to benefit others, such as helping, sharing, cooperating, and comforting. Social psychologists study why people help and why they sometimes fail to help.

The bystander effect is central here. Research following the Kitty Genovese case led to the conclusion that people are less likely to help in emergencies when others are present. The explanation is not simply apathy. It involves:

• diffusion of responsibility,
• pluralistic ignorance,
• fear of embarrassment,
• and ambiguity about the situation.

For example, if several people see someone collapse in public, each may assume someone else will act or may interpret the event as less serious than it is.

Latané and Darley’s Decision Model

A useful framework for helping behaviour is the stepwise decision model:

1. Notice the event
2. Interpret it as an emergency
3. Assume responsibility
4. Know how to help
5. Decide to implement help

Failure at any step can stop intervention. This model is excellent for exams because it breaks helping into concrete cognitive stages.

Aggression Theories

Aggression is behaviour intended to harm another person. Social psychology offers several explanations:

Frustration–Aggression Hypothesis

Frustration may increase the likelihood of aggression, especially when goals are blocked. However, frustration does not always produce aggression; it depends on interpretation, norms, and context.

Social Learning Theory

Aggression is learned through observation, imitation, and reinforcement. Children may learn aggressive scripts by watching family members, peers, media, or role models. This theory is especially useful because it explains why aggression can be culturally transmitted.

Cognitive Neoassociation and Arousal

Aggression can also be linked to physiological arousal and situational cues. Heat, provocation, and hostile interpretation can increase the likelihood of aggressive responses.

Comparing Prosocial and Aggressive Behaviour Theories

A useful exam strategy is to compare why people help and why they harm. Both are influenced by:

• interpretation of the situation,
• social norms,
• perceived responsibility,
• and learned models.

For instance, in a crowded street, a person may either help a fallen stranger or ignore them depending on whether they notice the event, interpret it as serious, and feel responsible. Similarly, aggression may depend on whether a person interprets a remark as insulting or neutral. In both cases, cognition and social context matter.

Final Evaluation of Key Theories

The most important thing to remember about SPSS201 social psychology theories is that none of them explains everything. Conformity theory explains group pressure well, but not all decision-making. Cognitive dissonance explains consistency motives, but not all attitude change. Social identity theory explains group bias, but not every form of inequality. Realistic conflict theory explains competition, but not identity-based discrimination where no material conflict is obvious.

The strongest exam answers therefore do not try to force every example into one theory. Instead, they:

• identify the best-fit theory,
• acknowledge an alternative,
• explain why one explanation is more convincing in that case,
• and discuss the limits of each theory.

High-Value Exam Comparisons

Topic	Theory	Main Idea	Common Limitation
Conformity	Normative and informational influence	People follow groups for approval or information	Does not explain all independence or resistance
Obedience	Authority and agentic shift	People obey legitimate authority	Ethical concerns and historical context
Attribution	Internal vs external causes	People explain behaviour by person or situation	Bias toward dispositional explanations
Dissonance	Need for consistency	Inconsistency causes discomfort and attitude change	Not all people experience dissonance equally
Prejudice	Social identity theory	Group membership shapes bias	Underplays structural inequality
Intergroup conflict	Realistic conflict theory	Competition over resources causes hostility	Does not explain bias without competition
Helping	Bystander intervention model	Help depends on cognitive steps	Situational models may understate personality
Aggression	Social learning theory	Aggression is learned by observation	Does not fully explain spontaneous aggression

How to Write a Strong NMU Exam Answer

A top-quality response usually follows this pattern:

1. State the theory accurately
2. Explain the mechanism
3. Use a classic study
4. Apply it to a real-life example
5. Evaluate strengths and weaknesses
6. Compare it with another theory if relevant

For example, if asked about prejudice, one could explain social identity theory, then use the minimal group paradigm, then apply it to student group rivalry, and finally compare it with realistic conflict theory. This structure shows depth and command of the material.

Closing Synthesis

Social psychology is powerful because it reveals that ordinary people are profoundly shaped by the social world. Yet it also shows that people interpret, justify, resist, and negotiate social pressure in complex ways. SPSS201 exam success depends on seeing these theories not as isolated names, but as different lenses on the same human reality. Conformity, cognition, identity, persuasion, helping, and aggression are all connected by one central insight: behaviour is never only personal; it is always social.

If one theory must be remembered as the backbone of the subject, it is this: social behaviour is produced by the interaction of person and situation. Everything else in the module elaborates that point in different ways.
