The Sociocultural Approach
Psychology does not happen in a vacuum. Every thought, decision, and behaviour occurs within a social world, shaped by the groups we belong to, the cultures we are raised in, and the people we observe. The sociocultural approach takes this seriously, asking how social context, cultural norms, and group membership can explain why people think and act the way they do.
The understandings in this section move from individual-level processes (cognitive dissonance, compliance, conformity) through cultural frameworks (dimensions, emic and etic approaches, enculturation) to broader identity and learning theories (acculturation, social identity, social learning). Each one gives you a different lens on the same question: how does the social world get inside the individual?
In IB Psychology, a claim without a named study is a weak claim. As you work through each concept, pay attention to the researcher, the method, and the finding. Those three elements are what an examiner wants to see.
Cognitive Dissonance
A state of psychological tension that arises when a person holds two conflicting beliefs, attitudes, or behaviours at the same time. This discomfort motivates the individual to reduce the inconsistency by changing their attitude, belief, or behaviour.
The key idea is that people are motivated to maintain internal consistency. When a behaviour conflicts with a belief, something has to give. It is usually easier to change the belief than the behaviour.
A person who values their health but continues smoking experiences dissonance.
Rather than quitting, they may reduce the discomfort by telling themselves the risks are exaggerated, or that they will quit eventually. The behaviour stays the same; the belief adjusts around it.
Festinger and Carlsmith (1959) provided the classic experimental demonstration. Participants performed a genuinely dull task: turning pegs on a board. They were then asked to tell the next participant it had been enjoyable. Half were paid 20. Afterwards, participants rated how much they had actually enjoyed the task.
The 20 group. The explanation: $20 provides sufficient external justification for the lie, so no dissonance is needed. One dollar does not, so those participants experienced real tension between their behaviour (lying) and their belief (the task was boring). To resolve it, they shifted their attitude. The task must have been somewhat enjoyable after all. This is attitude change through insufficient justification, and it is the core of cognitive dissonance theory.
The sociocultural dimension matters here. Dissonance is not purely internal. In collectivist cultures, deviating from group norms can intensify the tension, because social expectations carry more weight. People who migrate to cultures with different norms may also experience dissonance as their existing beliefs clash with new expectations.
Cognitive dissonance is not the same as hypocrisy. Hypocrisy is an observable mismatch between words and actions.
Cognitive dissonance is the internal psychological tension that may or may not follow from that mismatch, and it is the tension (not the mismatch itself) that drives behaviour change.
One alternative explanation is worth knowing. Bem (1967) proposed self-perception theory: people infer their own attitudes from their behaviour, just as they infer others' attitudes. On this view, no uncomfortable tension is required. The $1 participants simply observed themselves lie for a small sum and concluded they must have liked the task. This account is simpler, but it cannot easily explain situations where genuine physiological arousal accompanies the conflict.
