IB Psychology SL Topic 3 — Group Behaviour Paper 1 & 2 Sociocultural approach ~9 min read

Cultural Dimensions and How Groups Behave

Asch ran his line task in America and found roughly a third of answers went along with the group. Run the same task in Fiji and the number climbs. Same cards, same lines, very different result — because culture changes what going along with people actually means.

📚 What you need to know

Individualism and collectivism

Neither one is better. They are different answers to the same question: when what you want and what the group wants pull in opposite directions, which one wins?

Individualistic culturesCollectivist cultures
The unit that matters is ‘I’ and ‘me’The unit that matters is ‘we’ and ‘us’
Value independence, competing, standing outValue interdependence, harmony, fitting in
Upside: freedom and personal choiceUpside: community and a sense of belonging
Risk: feeling isolated and unsupportedRisk: losing personal identity and autonomy
Behaviour tends to revolve around the individualBehaviour tends to revolve around the group
Why this predicts conformity. If your culture teaches that harmony matters more than being individually right, going along with the group is not weakness — it is good behaviour. In a culture that prizes standing out, the same act looks like caving in. The behaviour is identical; the meaning is not.
Careful with the words. A culture is not ‘collectivist’ the way a person is tall. It is a tendency across a population, with huge variation inside it. Writing ‘more collectivist’ rather than ‘collectivist’ shows the examiner you understand that.

Key study: Smith & Bond (1993)

Rather than running a new experiment, Smith and Bond gathered up the ones that already existed. Asch’s line task had been replicated all over the world, and that gave them a rare chance: one procedure, many cultures.

Part of the studyWhat happened
AimTo find out whether conformity is affected by culture.
SampleA meta-analysis of 133 studies from 17 countries, covering both more collectivist and more individualistic cultures. Countries included France, Fiji, Ghana, Hong Kong, Japan, the UK and the USA.
ProcedureStatistical analysis of cross-cultural replications of Asch’s original line task. The findings were converted into an effect size for each country, reflecting the overall rate of conformity there.
ResultsThe highest effect sizes came from more collectivist countries: Fiji 2.48, Hong Kong 1.93, Japan 1.42. The lowest came from more individualistic countries: France 0.56, the Netherlands 0.74, the USA 0.90.
ConclusionConformity appears to be affected by culture, with more collectivist cultures showing higher rates than more individualistic ones.
Smith & Bond (1993): conformity by country Taller bar means more conformity in Asch-style tasks effect size 1.0 2.0 2.48 1.93 1.42 0.90 0.74 0.56 Fiji Hong Kong Japan USA Netherlands France more collectivist more individualist The three highest scores all came from more collectivist countries Effect size here stands for the overall rate of conformity found in that country
The pattern is clear, but the sample behind it is not even. Only two studies came from France and two from Fiji, against 79 from the USA.

EXAM PRACTICE

Discuss the use of one cultural dimension in explaining group behaviour. [22]

Step 1: name and define the dimension Individualism vs collectivism, from Hofstede’s IBM survey of over 60,000 people in more than 50 countries. Step 2: explain the link to behaviour Collectivist values put harmony above individual opinion, so conformity should be higher where those values are strong. Step 3: evidence Smith & Bond (1993): 133 studies, 17 countries. Fiji 2.48, Hong Kong 1.93 against France 0.56, USA 0.90. Step 4: evaluate the evidence Standardised procedure gives reliability, but 79 US studies against two French ones makes the comparison shaky, and a meta-analysis cannot explain the cause. Step 5: evaluate the dimension itself A country is not a culture, and globalisation is steadily merging values. Dimension + mechanism + evidence + two layers of evaluation Evaluate the study and the theory. Answers that only do one cap out around half marks.
