Difficulty: Introductory to Intermediate | Prerequisites: Part 1 notes (Intro, Research Methods, Personality).
This cluster covers how people construct and maintain a sense of who they are (the self), what drives their behaviour (motivations), and how they make sense of other people and the world (social beliefs and judgments). These topics connect directly: your self-concept shapes your motivations, and your motivations influence how you process social information. If you understand the self-serving bias from this section, you will immediately see why attribution errors (also covered here) are so persistent. You should be comfortable with the ABC model and basic research methods before tackling this material.
Your self-concept is built from self-schemas, shaped by culture (individualism vs. collectivism), and maintained through strategies like self-handicapping and self-presentation. Three master motives drive social behaviour: mastery, belonging and self-regard. When making judgments about others, people rely on two processing systems (fast/automatic and slow/deliberate), take mental shortcuts (heuristics) and commit predictable errors (like the fundamental attribution error).
Self-concept
The overall set of beliefs you hold about who you are. Think of it as your mental picture of yourself.
Self-schemas
Beliefs about yourself that organise and guide how you process self-relevant information. They work as mental shortcuts for interpreting your own behaviour.
Self-verification Theory
People prefer feedback that confirms their existing self-concept, even when that self-concept is negative.
Self-complexity
Having many distinct self-aspects (roles, identities). Higher self-complexity buffers against stress because a setback in one area does not collapse your entire identity.
Self-esteem
Your overall evaluation of your own worth. State self-esteem fluctuates with daily events; global self-esteem is more stable across time.
Self-efficacy
The belief that you can successfully perform a specific task. In simple terms, "I can do this."
Self-handicapping
Deliberately creating obstacles for yourself so that if you fail, you have a ready excuse, and if you succeed, it looks even more impressive.
Self-monitoring
The degree to which you adjust your behaviour to fit the social situation. High self-monitors are social chameleons.
Self-presentation
Actively managing the impression you make on others. Also called impression management.
Self-serving bias
The tendency to credit yourself for successes (internal attribution) and blame external factors for failures.
False consensus effect
Overestimating how many other people share your opinions or engage in the same behaviours you do.
False uniqueness effect
Underestimating how common your abilities or desirable behaviours are. The flip side of false consensus.
Impact bias
Overestimating how long and how intensely emotional events will affect you.
Self-fulfilling prophecy
When your expectation about someone leads you to act in ways that cause them to confirm that expectation. Also called behavioural confirmation.
Individualism
Cultural orientation prioritising personal goals, autonomy and individual identity.
Collectivism
Cultural orientation prioritising group goals and defining identity through group membership.
Independent self
Self-concept built around being a unique, autonomous individual with personal traits and goals.
Interdependent self
Self-concept built around social roles, relationships and group memberships.
Defensive pessimism
Setting low expectations as a way to manage anxiety. The low bar motivates you to prepare harder.
Your self-concept is the sum of everything you believe about yourself. It is not one thing but a collection of self-schemas, each acting as a lens for processing information.
Self-schemas filter what you notice and remember. A person with a strong "athletic" self-schema will pay more attention to sports-related information and recall it more easily.
Self-verification theory explains why people seek feedback that confirms their existing self-view, even when it is unflattering.
State self-esteem rises and falls with daily events (a good exam, a rejection).
Global self-esteem is your broader, more stable sense of self-worth.
Self-efficacy is task-specific: you can have high self-efficacy for cooking and low self-efficacy for public speaking.
Self-expansion is the idea that close relationships help us grow by incorporating aspects of the other person into our own identity.
Self-comparison vs. self-compassion: comparing yourself to others often lowers wellbeing. Self-compassion, treating yourself with the kindness you would show a friend, is the healthier alternative.
Self-handicapping – creating excuses in advance ("I did not study") to protect self-esteem if you fail.
Self-monitoring – adjusting your behaviour to fit social expectations. High self-monitors are skilled at reading rooms and adapting.
Self-presentation – the broad category of impression management. Everything from choosing what to wear to how you phrase an answer in class.
The self-serving bias is the tendency to take credit for good outcomes and blame the situation for bad ones.
It produces the false consensus effect ("everyone thinks like me") and the false uniqueness effect ("nobody is as talented as me").
The impact bias is related: we overestimate how long future emotional events will affect us.
When you expect someone to behave a certain way, you treat them accordingly, and they end up confirming your expectation.
This is also called behavioural confirmation. Classic example: a teacher who expects a student to be bright gives that student more attention, and the student performs better.
Individualist cultures (e.g. US, UK, Australia) emphasise personal achievement, autonomy and uniqueness. People tend to have an independent self-concept.
Collectivist cultures (e.g. Japan, China, many Latin American countries) emphasise group harmony, duty and social roles. People tend to have an interdependent self-concept.
These cultural orientations shape everything from self-esteem to conformity to conflict resolution.
Bucket Model
A framework for organising specific social psychological needs into broader categories ("buckets").
Three Master Motives
The three overarching drives in social psychology: mastery (competence and control), connectedness/belonging (relationships and group membership), and self-regard (maintaining positive self-esteem).
Terror Management Theory
The idea that awareness of our own mortality creates anxiety, and we manage that anxiety by investing in cultural worldviews and self-esteem that give life meaning.
Cognitive Dissonance Theory
The discomfort you feel when you hold two contradictory beliefs, or when your behaviour conflicts with your beliefs. You are motivated to reduce that discomfort.
Induced Compliance (Insufficient Justification)
When you are persuaded to act against your beliefs for little reward, you experience dissonance and change your attitude to match your behaviour. The classic example: participants paid $1 (not $20) to say a boring task was fun ended up rating it as more enjoyable.
Effort Justification
The more effort you invest in something, the more you value it, because admitting it was not worth the effort would create dissonance.
Mastery – the need to understand and control your environment. You want to feel competent.
Connectedness/Belonging – the need for social bonds. Humans are fundamentally social, and isolation is psychologically damaging.
Self-Regard – the need to maintain positive self-esteem. Much of social behaviour (self-serving bias, self-presentation) serves this motive.
Awareness of death creates existential anxiety. People cope by clinging to cultural worldviews that provide meaning and by bolstering self-esteem. When mortality is made salient (e.g. in experiments), people become more defensive of their worldview and more hostile toward those who threaten it.
When behaviour and beliefs conflict, the resulting discomfort motivates change, usually in the belief rather than the behaviour.
Induced compliance – the $1 vs. $20 experiment (Festinger and Carlsmith). Participants paid only $1 to lie about a boring task changed their attitude ("it was quite fun") because the small payment gave them insufficient justification for lying.
Effort justification – the harder you worked to get into a group, the more you value that group, even if it turns out to be mediocre.
System 1 (Automatic Processing)
The fast, intuitive, unconscious way of thinking. It runs on heuristics and gut feelings.
System 2 (Controlled Processing)
The slow, deliberate, conscious way of thinking. It requires effort and attention.
Overconfidence Phenomenon
The tendency to be more confident in the accuracy of your beliefs than you should be.
Belief Perseverance
Clinging to an initial belief even after the evidence supporting it has been discredited.
Representativeness Heuristic
Judging the likelihood of something by how well it matches a prototype or stereotype. In simple terms, "if it looks like a duck, it must be a duck."
Availability Heuristic
Estimating frequency or probability based on how easily examples come to mind.
Counterfactual Thinking
Imagining alternative outcomes to events that have already occurred. The "what if" mental exercise.
Illusory Correlation
Perceiving a relationship between two things when none exists, or perceiving a stronger link than the data support.
Dispositional Attribution
Explaining someone's behaviour by pointing to their personality, character or internal traits.
Situational Attribution
Explaining someone's behaviour by pointing to external circumstances or context.
Spontaneous Trait Inference
Automatically and effortlessly inferring a personality trait from observing someone's behaviour, without intending to.
Fundamental Attribution Error (FAE)
The tendency to overweight dispositional factors and underweight situational factors when explaining other people's behaviour. In simple terms, blaming the person rather than the situation.
Ultimate Attribution Error
Applying attribution biases at the group level: attributing negative behaviour by outgroup members to their disposition and positive behaviour to luck or circumstance.
Covariation Model (Kelley)
A framework for attribution based on three types of information: distinctiveness (does the person act this way only in this situation?), consensus (do others act this way in the same situation?) and consistency (does the person always act this way in this situation?).
System 1 (automatic) – fast, effortless, relies on heuristics. Handles most everyday judgments.
System 2 (controlled) – slow, effortful, logical. Engages when a problem is novel or important.
Most social judgments default to System 1 unless something flags the need for deeper processing.
People consistently overestimate how accurate their judgments are.
Confirmation bias feeds overconfidence: you seek evidence that supports what you already believe.
Belief perseverance keeps initial beliefs alive even after the evidence behind them is debunked. This is why first impressions are so powerful.
Representativeness – "this person looks like a librarian, so they probably are one." Ignores base rates.
Availability – events that are vivid, recent or emotionally charged feel more common than they are.
Counterfactual thinking – imagining how things could have turned out differently. Feeds regret ("if only I had...").
Illusory correlation – seeing patterns where there are none, or seeing stronger patterns than the data support. This underpins many stereotypes.
Dispositional attribution – explaining behaviour through internal traits ("she is rude").
Situational attribution – explaining behaviour through context ("she was having a terrible day").
Spontaneous trait inference – we automatically infer traits from behaviour, even without meaning to.
This is the big one. When judging other people, we overweight personality and underweight the situation. When judging ourselves, we do the reverse (actor-observer asymmetry). The FAE is stronger in individualist cultures.
To figure out why someone behaved a certain way, we look at three dimensions:
Distinctiveness – does this person behave this way only in this situation (high) or in many situations (low)?
Consensus – do other people behave the same way in this situation (high) or not (low)?
Consistency – does this person behave this way every time in this situation (high) or only sometimes (low)?
High distinctiveness + high consensus + high consistency = situational attribution. Low distinctiveness + low consensus + high consistency = dispositional attribution. High distinctiveness + high/low consensus + low consistency = chance/circumstance attribution.
Students often think the fundamental attribution error means we never consider the situation. We do, but we systematically underweight it relative to personality when judging others.
Students sometimes confuse the self-serving bias with the fundamental attribution error. The self-serving bias is about how you explain your own outcomes. The FAE is about how you explain other people's behaviour.
Students frequently assume cognitive dissonance always leads to attitude change. It does not. People can also reduce dissonance by adding consonant cognitions, trivialising the inconsistency, or changing the behaviour itself.
Students sometimes treat System 1 as "bad" and System 2 as "good." System 1 is efficient and usually accurate enough. System 2 is not always better; it is just slower and more deliberate.
⚠️ The fundamental attribution error is one of the most heavily tested concepts in the course. Be able to define it, give an example and explain why it is more common in individualist cultures.
⚠️ Know the $1 vs. $20 experiment (Festinger and Carlsmith) inside and out. Exams frequently describe a scenario and ask you to apply cognitive dissonance theory.
⚠️ Be prepared to apply Kelley's covariation model. You may be given a scenario with distinctiveness, consensus and consistency information and asked what attribution follows.
⚠️ Understand the difference between self-serving bias, false consensus and false uniqueness. These are commonly confused in multiple-choice questions.
⚠️ Know System 1 vs. System 2 and be able to identify which is at work in a given scenario.
True or False: Self-efficacy and self-esteem are the same thing. (False. Self-efficacy is task-specific confidence; self-esteem is overall self-worth.)
Fill in the blank: The three master motives are mastery, ___, and self-regard. (Connectedness/Belonging.)
True or False: In the Festinger and Carlsmith experiment, participants paid $20 showed more attitude change than those paid $1. (False. The $1 group changed more.)
Name the three components of Kelley's covariation model. (Distinctiveness, consensus, consistency.)
True or False: The fundamental attribution error applies to how we explain our own behaviour. (False. It applies to how we explain other people's behaviour.)
Q: A student does not study for an exam and tells friends beforehand, "I am going to fail." What self-concept strategy is this?
A: Self-handicapping. By creating a ready-made excuse, the student protects self-esteem if the result is poor and looks even better if the result is good.
Q: Explain the difference between the false consensus effect and the false uniqueness effect.
A: The false consensus effect is overestimating how many people share your opinions and undesirable behaviours. The false uniqueness effect is underestimating how common your abilities and desirable behaviours are. Both stem from the self-serving bias.
Q: In Kelley's covariation model, a person laughs at a specific comedian (high distinctiveness), everyone else also laughs at that comedian (high consensus), and this person laughs every time they see that comedian (high consistency). What attribution follows?
A: Situational attribution. The pattern points to something about the comedian (the situation), not the person.
Q: What is cognitive dissonance, and how did the Festinger and Carlsmith study demonstrate it?
A: Cognitive dissonance is the discomfort from holding contradictory cognitions. In the study, participants who were paid only $1 to say a boring task was interesting experienced more dissonance (insufficient justification for lying) and changed their attitude to reduce it, rating the task as more enjoyable than those paid $20.
Q: Why is the fundamental attribution error more common in individualist cultures?
A: Individualist cultures emphasise personal agency and traits, making people more inclined to explain behaviour through disposition. Collectivist cultures are more attuned to situational and relational factors.
The self-serving bias connects to the Attitudes unit: self-presentation and cognitive dissonance both appear there as mechanisms through which behaviour shapes attitudes. Attribution theory links directly to Perception (covered in Part 4), where perceiver effects and thin-slice judgments build on the same tendency to make rapid, often biased inferences. The three master motives (mastery, belonging, self-regard) will reappear in Conformity and Persuasion, where belonging needs drive conformity and self-regard needs make people susceptible to flattering persuaders.
