RESEARCH STUDY 3.4: Dr. Kang, a cognitive psychologist, conducts an experiment examining the effect of emotion on memory. He provides lists of 15 words to two groups of participants at his university. He puts the names of all the participants in a hat. The first 20 names he assigns to Group A and the last 20 he assigns to Group B. Group A is given a list of words that are very emotional in content (e.g., passion, murder). Group B is given a list of words that are neutral in content (e.g., houseplant, desk). He then measures how many words each group is able to remember after being distracted for 5 minutes by watching a video about the history of the university. He finds that Group A remembers 15% more words than Group B. Based on this study, Dr. Kang can make which of the following claims?
NOT distraction is associated with worse memory
RESEARCH STUDY 3.3: Anton and his friends are discussing a study he read about in his developmental psychology class. In the study, the researcher made the claim that most middle school students who are bullied have low self-esteem. Clarissa questions the study, saying, "I am not sure that I am convinced. I am not sure you can really measure being bullied." Quinn also questions the study, saying, "Which middle school students did they study? I am curious if they included both private and public school students." Manish also is curious about the study, asking, "I wonder how strong the relationship is between bullying and self-esteem. Could you predict one from the other?" Anton is concerned that the researcher made a Type I error. What does that mean?
The researcher concluded there was a relationship, but there isn't really one

RESEARCH STUDY 3.1: Anderson is reading his morning paper and sees the following headline: "Men Should Avoid Rock Music When Playing Board Games." (This headline is based on a study conducted by Fancourt, Burton, & Williamon, 2016.) In the study, men and women played the game "Operation" when listening to different types of music.

RESEARCH STUDY 3.2: Dr. Ramon makes the following claim: "Watching television leads people to spend less time communicating with their spouses, study says."

Their results showed that White women can be threatened by racism, and men of color threatened by sexism, and that these perceptions made participants expect unfair treatment. In this study, ________ is a conceptual definition of one of their primary variables.

Their results showed that White women can be threatened by racism, and men of color threatened by sexism, and that these perceptions made participants expect unfair treatment. Because of the design of this study, Sanchez and colleagues are likely more interested in ____________ than _____________.
construct validity; generalizing to all minority groups

The reviewer is questioning which of the following?
the construct validity of the study
