Syllabus: How Do Attitudes Form and Change?
Follow how involvement changes the contrasts between stronger and weaker arguments and between attributed sources.
Why you’re reading it. Study persuasion as conditional on the reader and situation, rather than a property of a message alone.
A question to consider. What outcome pattern would support the claim that personal relevance changes sensitivity to argument quality?
Why this reading
Does persuasion depend on an argument's quality or its source? This experiment asks how personal relevance changes their relative influence.
Before you read
A factorial design varies several factors together. An interaction means one factor's effect depends on another. Here personal involvement, argument quality, and attributed expertise were varied in messages about a university examination requirement.
Read for
- Reconstruct the eight experimental conditions and the argument-quality pretest.
- Use Figure 1 to compare the two interactions, not just average agreement.
- Check what recall measures and the no-message comparison add to the inference about processing.
Consider afterwards
- How could the same expertise cue influence a judgment differently when a proposed requirement affects the reader next year rather than much later?
Editorial context
The main experiment involved 145 U.S. undergraduates and immediate ratings, not lasting behavior change. The 18-person no-message control was collected about two years later, as footnote 3 explains. The manipulated conditions support comparisons, but the proposed processing routes require inference; personal relevance is not a universal switch between two fixed kinds of thinker.
