The beginning of Chapter 11 in our Yalom text revisits the concept of interpersonal learning which was initially discussed in Chapter 2. This is a key therapeutic factor in group work. 1) Describe your understanding of interpersonal learning. 2) What role does real-time feedback play in this process?
You find a nationally representative survey with information on media consumption and voting behavior. There is also information on controls. You intend to run a regression where the dependent variable is voting behavior and the independent variable is media consumption and control for any confounders that are in the dataset. You will interpret the coefficient on media consumption as a causal effect. a. How or why does controlling for confounders help you answer your research question? b. What are the main confounders you will control for? Please explain why the variable is a confounder. What types of survey measures might you use? c. Gallup runs a survey on ideology immediately before the voting outcomes are measured. Is this variable a mechanism or a confounder? Would you control for it in your regression? d. Are there any issues of reverse causality? e. Are there issues of validity and reliability for your variables of interest as measured through a survey?
