Exam 3: Three Claims, Four Validities: Interrogation Tools for Consumers of Research

Stefan wants to make a causal claim in his dissertation. Which of the following is necessary?

Which of the following is the difference between claims based on personal experience (anecdotal claims) and frequency claims?

Name the four validities used to interrogate claims. If you were to question a study's four validities, provide a question you might ask related to each validity.

From a Time.com article entitled "Why Men Shouldn't Listen to Rock Music While Playing Board Games," published on December 13, 2016. Researchers Fancourt, Burton, and Williamon wanted to find out whether different types of music would impact participants' performance on a mock-surgery game, "Operation." Many real-life surgeons listen to music while operating, so the authors were interested in whether this may actually help performance, and whether that differed by sex of the participant. The psychologists asked male and female participants to play the mock-surgery game, "Operation," in which they needed to remove three different organs from a "patient" using tweezers. The experimenters played either rock music, classical music, or operating-room sounds. They found that the type of music made a difference on the performance of male participants, who were slower to complete the task (in seconds) while listening to rock music compared with classical music. The performance of female participants did not differ based on the type of music they listened to. What type of claim is the author making in this study? Explain why you think this is the claim being made.

Jenny reads the following headline on an online article: "If You're Sexist, People Will Think You're Racist, and Vice Versa." (This headline is based on a study conducted by Sanchez and colleagues, 2017.) This study found that members of stigmatized groups are threatened by prejudice directed at other stigmatized groups. 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, the article's headline is because .

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. Dr) Kang sends his study to a journal to be published. One of the peer reviewers questions the way Dr. Kang manipulated emotion, arguing that being exposed to emotional words does not make one emotional. The reviewer is questioning which of the following?

To evaluate how well a study supports a frequency claim, you need to focus most on evaluating which of the following validities?

The results of this study can be generalized to which of the following groups?

You read a news article titled, "New Drug Reduces OCD Symptoms in Mice" about a recent scientific study. To evaluate whether the title's claim is supported, you should do which of the following?

Indicate which variables are manipulated and which variables are measured in this study.

Which of the following is a reasonable causal claim?

A common finding in the study of aggression is that exposure to television is associated with increased aggressive behavior in children. You know this relationship may not be causal because you are not sure which occurred first: watching television or being aggressive. You are questioning which of the following rules of causation?

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. Male participants performed worse when listening to AC/DC than when listening to Mozart, but female participants' performance did not differ based on music. Which of the following is a variable in this study?

A Type I error is known as which of the following?

Which of the following is NOT a research claim?

Which of the following is an association claim?

Who is responsible for deciding which validity is prioritized in a study?

Dr. Ramon makes the following claim: "Watching television leads people to spend less time communicating with their spouses, study says." Dr. LaSalle makes the claim: "Research shows that making more money correlates with spending less time talking with your spouse." Which type of claim is Dr. LaSalle making?
