Syllabus: How Do We Build and Test Psychological Theories?

Trace one proposed prediction through its concepts, measures and auxiliary assumptions.

Why you’re reading it. Establish why groundwork can be a scientific contribution in its own right.

A question to consider. For the claim that interruptions impair learning, what must be specified before an experiment could test the explanation?

Why this reading

Scheel and colleagues ask what makes a hypothesis test informative about a theory. Their argument gives conceptual clarification, descriptive observation and measurement development a substantive place in research.

Before you read

A derivation chain connects a theory to an observable prediction. It includes auxiliary assumptions: additional claims about measures, manipulations and circumstances that the main theory does not supply.

Read for

  1. Follow how an uncertain concept or measure can weaken an otherwise careful test.
  2. Compare the kinds of groundwork proposed for different weaknesses in the chain.

Consider afterwards

  1. A study finds no relationship between a questionnaire score and behavior. What would you need to know before treating that result as evidence against a theory?

Editorial context

This is a methodological argument, not evidence that hypothesis testing is generally unhelpful. The authors advocate informative tests supported by prior work and acknowledge that standards for adequate groundwork depend on the research problem. Nonconfirmatory work also requires transparency and scrutiny.
