Question

Read the short scenario below and then name and explain which type of validity each doctors is addressing in their questions (Hint: each doctor is addressing a different type of validity). Dr. Lopez and his colleagues (Dr. Jefferson and Dr. Shaw) are discussing the following headline “Playing Video Games Leads to an Increase in a Growth-Mind Set in College Students”. Dr. Lopez, Dr. Jefferson, and Dr. Shaw have many concerns. Dr. Lopez utters, “Did the researcher randomly sample from all college students or did he just study his own college students in his classes? Maybe this finding just holds true for his students for some reason.” Dr. Shaw added to the discussing by asking, “It so strange that playing video games would cause an increase in growth-mind set.” “Did the researchers conduct an experiment or just a correlational study?”” If it is a correlational study, a third variable could be increasing video game playing as well as a growth mind-set.” Dr. Jefferson asks, “An increase in a growth-mind set can mean so many things.” “How did they operationalize an increase in growth-mind set?”
