This is the opening chapter of social psychology, covering what the field is, where it came from, and the major lenses researchers use to study social behaviour. It lays the groundwork for every topic that follows in the course. You do not need prior psychology knowledge, but familiarity with basic scientific reasoning helps. If you have taken an introductory psychology course, you will recognise some of the historical perspectives (behaviourism, psychoanalysis) but will see them reframed through a social lens.
Social psychology is the scientific study of how people's thoughts, feelings, and actions are shaped by other people and by the situations they find themselves in. The field grew out of three older traditions (instinct theory, psychoanalysis, behaviourism) and is now organised around five integrative perspectives: cognitive, evolutionary, cultural, existential, and neuroscience. Four core assumptions run through the discipline: behaviour is a joint product of person and situation, reality is socially constructed, social cognition powerfully shapes what we do, and the scientific method is the best tool for understanding all of it.
Social psychology
The scientific study of the causes and consequences of people's thoughts, feelings, and actions regarding themselves and other people. In simple terms, it is the science of how we think about, feel about, and behave towards one another.
Dispositions
Consistent preferences, ways of thinking, and behavioural tendencies that show up across different situations and over time. Think of these as the stable personality traits a person carries from one setting to the next.
Situation (the power of the situation)
The external context that shapes behaviour, often more strongly than people expect. A classic example: nearly everyone in a library tends to be quiet, regardless of personality.
Social cognition
The set of mental processes by which people perceive, remember, and interpret events and individuals in their social world, including themselves. In simple terms, it is the mental machinery you use to make sense of other people and your own place among them.
Cultural knowledge
A store of information accumulated in a culture about how the world works. Think of it as the shared "common sense" of a society, things people believe without having tested them personally (e.g. germ theory of illness).
Confirmation bias
The tendency to process information in a manner that conforms to what we already desire and expect. It affects what we pay attention to, how we interpret ambiguous evidence, and what we remember afterwards.
Cognitive misers
The idea that people tend to avoid strenuous mental effort, latching on to quick and easy answers rather than thinking things through carefully. In simple terms, our brains prefer shortcuts.
Causal attribution
An explanation a person constructs for why an event happened or why someone behaved in a particular way. Morgan thinks her mum is ignoring her because of a curfew argument: that is a causal attribution.
Social comparison
The process of evaluating ourselves by looking at other people. A child judging her own height by glancing around at classmates is using social comparison.
Stereotype threat
The phenomenon in which members of a negatively stereotyped group perform worse on a task when the stereotype is made salient, because they worry about confirming it. In simple terms, being reminded of a negative group stereotype can undermine your performance.
Cultural animals
The description of humans as beings who create their own symbolic conception of reality. This is what distinguishes us from animals who merely react to stimuli; we build shared systems of meaning.
A priori causal theory
A pre-existing explanation, often drawn from cultural knowledge, that people use to account for their own or others' behaviour, whether or not it is correct. The silk-stockings study (Nisbett and Wilson) showed that shoppers explained their choices with plausible but wrong reasons, ignoring the real cause (positioning on the table).
Cognitive conservatives
A near-synonym for cognitive misers, describing the human tendency to conserve mental energy and stick with familiar interpretations.
The very first social psychology textbook drew on Herbert Spencer's extensions of Darwin's ideas about evolution.
McDougall proposed that all social behaviour is the product of evolutionarily acquired, specific instincts.
This was the earliest formal approach to explaining social behaviour, predating both psychoanalysis and behaviourism in the field.
Emphasised that human behaviour is primarily driven by unconscious desires, particularly around sex and aggression.
The notion that much of social behaviour is driven by forces outside conscious awareness is critical to this perspective.
While social psychology moved away from Freud's specific claims, the broader idea that people lack full insight into their own motives remains influential.
Rejected instinct and the unconscious as unmeasurable. Focused exclusively on observable behaviours and how they are shaped by reinforcement and punishment.
Behaviourists were primarily interested in measuring observable behaviours, not mental states or unconscious drives.
The belief that social behaviour is shaped by experiences is reflective of behaviourism.
WWII had a major influence on the history of social psychology, prompting urgent questions about obedience, prejudice, propaganda, and group conflict.
The field shifted in the second half of the 20th century from broad views of human social behaviour toward specific, topic-based theories grounded in empirical research.
In the first half of the 20th century, social psychology tended to stress broad views of human social behaviour.
From the second half of the 20th century to the present, the field stresses specific, topic-based theories.
In recent decades, five integrative perspectives have emerged to pull these threads back together (covered in the next section).
Focuses on how people perceive, remember, and interpret events and individuals in their social world.
The primary metaphor for understanding humans here is the information processor.
People are viewed as intuitive scientists who use reasoning and observation to understand the social world (attribution theory).
Key insight: people are also cognitive misers who conserve mental effort, often relying on shortcuts and confirmation bias.
Seeks to identify how and why social behaviour develops as a consequence of evolved adaptations.
The concept of adaptation is most central to this perspective.
Rooted in Darwin's ideas, but distinct from McDougall's earlier instinct-based approach in that it uses modern evolutionary theory and empirical testing.
Focuses on the influence of culture and broader societal norms on thought, feeling, and behaviour.
Humans are described as "cultural animals" because they create their own symbolic conception of reality.
Cultural knowledge, the shared store of information about how the world works, is a central concept here.
Attempts to identify core human motivations to understand oneself and find meaning, especially in the face of concerns about mortality.
Ezekiel working hard because he feels his life is meaningful is an example best understood through this lens.
Concerned with questions such as: what makes life worth living, and how do people cope with awareness of death?
Studies the neural processes that occur during social judgement and behaviour.
Tools include brain imaging and measuring brain waves (EEG), as well as assessing cardiovascular functioning.
Assessing people's behaviours is NOT considered a neuroscience measurement tool (that belongs to general observation and behaviourism).
These five perspectives are not competing alternatives. They fit together: brains (neuroscience) evolved (evolutionary) to process social information (cognitive), within local cultural conditions (cultural), and with a uniquely human awareness of existence and mortality (existential).
Behaviour is a joint product of the person and the situation. Situations exert a strong influence on behaviour, but people's individual differences (dispositions) also shape what they do. Simon being extraverted yet quiet at school illustrates the interaction of situation and personality.
Behaviour depends on a socially constructed view of reality. People compare themselves to others and constantly think about the beliefs, attitudes, and actions of those around them. Social comparison is the mechanism here.
Social cognition has a strong influence on social behaviour. The mental processes by which we make sense of our social world, including causal attributions and confirmation bias, powerfully shape our actions.
The scientific method is essential for understanding the roots of social behaviour. People's own explanations for their behaviour are often inaccurate (Nisbett and Wilson's research), so rigorous empirical testing is needed.
Note what is NOT a core assumption: "Behaviour is determined exclusively by situations" is false. The first assumption is explicitly interactionist, acknowledging both person and situation.
"Social psychology is just common sense." Cultural knowledge often feels like common sense, but research frequently contradicts it. The scientific method exists precisely because intuition is unreliable.
"People know why they do what they do." Nisbett and Wilson's silk-stockings study showed that people generate plausible-sounding but incorrect explanations for their own choices. We have access to the products of our thought processes, but little access to the processes themselves.
"Behaviour is determined by personality alone." Students often underestimate the power of the situation. The field's first core assumption is interactionist: behaviour is always a joint product of person and situation.
"The cognitive perspective and the evolutionary perspective are the same thing." They ask different questions. The cognitive perspective asks how people process social information right now; the evolutionary perspective asks why those processing tendencies evolved in the first place.
Know the definition of social psychology and what distinguishes it from philosophy or cultural knowledge (answer: the emphasis on the scientific method).
Be able to match each of the three historical perspectives (instinct, psychoanalytic, behaviourist) to its key claim and its leading figure.
Be able to match each of the five modern perspectives to its core concept (e.g. adaptation belongs to evolutionary, not cultural).
Know all four core assumptions and, critically, know that "behaviour is determined exclusively by situations" is NOT one of them.
Understand stereotype threat well enough to apply it to novel scenarios (Jacob the blue-collar worker, Black students reminded of their race before a test).
Confirmation bias appears repeatedly. Expect questions that give you a scenario and ask you to identify the concept (Carol only noticing potholes, students reading capital-punishment studies, Emiliano researching dogs vs cats).
The distinction between cognitive misers and confirmation bias: cognitive misers describes the tendency to conserve effort; confirmation bias describes the tendency to process information in line with existing beliefs. They overlap but are not identical.
True or False: Behaviourists were primarily interested in measuring unconscious drives. Answer: False. They focused on observable behaviours.
Fill in the blank: The tendency to process information in a way that confirms what we already believe is called _____. Answer: confirmation bias.
True or False: "Behaviour is determined exclusively by situations" is one of the four core assumptions of social psychology. Answer: False. The correct assumption is that behaviour is a joint product of person AND situation.
Fill in the blank: The concept of adaptation is most central to the _____ perspective. Answer: evolutionary.
True or False: Assessing people's behaviours is a tool of the neuroscience perspective. Answer: False. Neuroscience tools include brain imaging, brain waves, and cardiovascular measurement, not general behavioural observation.

Confirmation bias reappears throughout the course, particularly in chapters on attitudes, persuasion, and prejudice. Stereotype threat connects directly to later material on prejudice, discrimination, and group identity. The person-vs-situation debate underpins nearly every topic in social psychology, from conformity to aggression to helping behaviour. Understanding these foundational concepts here will make every subsequent chapter easier to parse.
