Are we measuring the right things? Identify the main variables in the causal claim of the Pucker article and draw a simple concept map (i.e., a picture) to illustrate it (See Dyer, Chapter 2 for a refresher on concept maps). Then, conduct a more detailed causal analysis of the article based on the material presented in Dyer, Chapter 5. Consider, the following: What are the primary variables of interest? What outcome/effect is Pucker especially interested in? Can you identify potential rival causes or explanations for the phenomena being examined? Are any of the following relevant to this causal relationship: differences between groups, reverse causation, a third factor, or order of occurrence (post hoc ergo propter hoc)
