Soares, J. S., & Storm, B. C. (2019). Putting a negative spin on it: Using a fidget spinner can impair memory for a video lecture. Applied Cognitive Psychology, 34(1), 277-284. DOI:10.1002/acp.3610

1. What is the main research question that the studies are trying to answer? What type of claim (causal, associational, or frequency) are the studies investigating?

2. Is there a hypothesis or hypotheses stated? If so quote the text that gives the hypothesis or hypotheses.

3. Beginning with study 1, what type of design did this study have?

4. What were the variables in study 1, and how were these variables operationally defined? (Note, there was one independent variable and two dependent variables. Be sure to consider them all. Thinking about how variables were operationally defined will help you critique construct validity later).

5. What were the results of the study for each of the dependent variables?

6. Are there plausible explanations for the results of study 1 besides the authors' preferred explanation? (Note, considering these alternative explanations will help you think about internal validity).

7. Think about each of the four major validities (internal, external, construct, and statistical). What are the notable strengths and weaknesses of study 1 in terms of those validities? Explain your reasoning using concepts from the lectures and book. Pay special attention to the types of validity that may be especially important for this type of design.

8. What type of design did study 2 have?

9. What were the variables in study 2, and how were these variables operationally defined? (Note, there was one independent variable and three dependent variables. Be sure to explain them all. Thinking about how variables were operationally defined will help you critique construct validity later).

10. What were the results of the study for each of the dependent variables?

11. Are there plausible explanations for the results of study 2 besides the authors' preferred explanation? (Note, considering these alternative explanations will help you think about internal validity).
