Syllabus: How Do We Build and Test Psychological Theories?
Ask which commitments become visible at each stage of the proposed pathway.
Why you’re reading it. Prepare to read a formal psychological model as an argument with explicit choices.
A question to consider. How could a model’s implementation reveal an ambiguity that its verbal description concealed?
Why this reading
Guest and Martin show how specifying and implementing a model can expose assumptions that remain hidden in an intuitive explanation. Their account separates a theory from the choices needed to turn it into predictions.
Before you read
A specification states rules precisely; an implementation realizes those rules in code. A model of a proposed psychological process differs from a statistical model used to summarize observations.
Read for
- Follow what changes as the simple worked example moves from an idea to a specification and implementation.
- Use the proposed research pathway to locate assumptions and points at which a disappointing result might require revision.
Consider afterwards
- If two programs produce different predictions from the same verbal theory, what would you inspect before declaring the theory inconsistent?
Editorial context
The article argues for a central role for computational modeling; it does not demonstrate that coding alone guarantees a sound explanation. The authors discuss questionable practices in modeling itself, including selective reporting of implementations. Their proposal invites scrutiny of both models and the research process.
