Syllabus: How Can We Compare Psychological Processes Across Cultures?
Compare proposed mediators, observed practices and experimental manipulations as different forms of evidence.
Why you’re reading it. Finish by designing a comparison that can discriminate among explanations.
A question to consider. How would you test whether responsibility scores reflect family obligations, opportunities to act or response conventions, and what causal uncertainty would remain after your proposed study?
Why this reading
Matsumoto and Yoo ask what evidence links a group difference to the cultural process proposed to explain it. Their methodological agenda connects measured practices, competing models and experimental designs.
Before you read
An unpackaging study measures a proposed explanatory process alongside a group comparison. A mediator is a variable placed on a proposed pathway; a statistical mediation result requires further assumptions for causal interpretation.
Read for
- Follow the difference between naming a cultural dimension and testing a process.
- Compare what observational and experimental designs can establish about that process.
Consider afterwards
- How could you test whether a difference in cooperation reflects sanctions, relationship expectations or participant recruitment?
- What would connect a brief experimental manipulation to everyday experience?
Editorial context
This agenda and its illustrations reflect the 2006 literature. Treat its proposed biological and cultural models as claims requiring evidence. Statistical mediation alone does not identify a causal pathway, and manipulating a cue does not recreate a cultural history. The paper is useful for designing discriminating comparisons; it does not supply a final explanation of national differences.
