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.

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? a. The statistical validity of the study b. The internal validity of the study c. The construct validity of the study d. The external validity of the study e. He is questioning all of the validities
c. The construct validity of the study
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.Which of the following is the independent variable in Dr. Kang's study? a. The length of the distractor task b. The number of words remembered c. The emotional or neutral word list d. The number of words on the list e. All of the above are independent variables
c. The emotional or neutral word list
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's decision to assign participants randomly to Group A and Group B increases which of the following? a. The covariance of the study b. The temporal precedence of the study c. The internal validity of the study d. The external validity of the study e. The construct validity of the study
c. The internal validity of the study

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 can make a causal claim that "emotion enhances memory" because: a. There is a numeric difference between Groups A and B b. Reading the words occurred before recalling the words c. Dr. Kang treated Groups A and B identically except for the emotional word content d. All of the above allow him to make a causal claim e. He cannot make a causal claim based on his study
d. All of the above allow him to make a causal claim
Dr. Sheffield is a clinical psychologist who specializes in treating pathological gambling. Pathological gambling is defined as being unable to resist impulses to gamble. Bothered by not having a good measure that he can give to clients to determine whether they are suffering from this condition, he creates a new measure of pathological gambling. The measure has 15 questions and it takes 20 minutes to complete To test his measure, Dr. Sheffield gives his measure to a group of his clients and at the same time measures how many times they have been gambling in the past month. He predicts that clients who score higher on his measure will also report gambling more times in the past month. This procedure is meant to provide evidence for which of the following? a. Face validity b. Content validity c. Predictive validity d. Concurrent validity e. Discriminant validity
d. Concurrent validity
Stefan wants to make a causal claim in his dissertation. Which of the following is necessary? a. He must make a frequency claim first. b. He must manipulate his two variables. c. He must measure his two variables. d. He must conduct an experiment. e. None of the above are necessary.
d. He must conduct an experiment.
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 a majority of 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." Refer to Research Study 3.3 above to answer the following question. Clarissa's concern is addressing which of the following? a. The study's operational validity b. The study's statistical validity c. The study's internal validity d. The study's external validity e. The study's construct validity
e. The study's construct validity
