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, Group B is given a list of words that are neutral in content. 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.

answer
Dr. Kline is planning on conducting a study next semester. He is curious as to whether sleep deprivation is associated with poorer cognitive performance. For example, if you sleep poorly the night before a big exam, will you do worse? Dr. Kline is especially curious about selective sleep deprivation, where people are kept from entering REM sleep. Using an electroencephalograph (EEG) to monitor brain waves, he plans to let participants sleep until they enter REM sleep then he will wake them. After the participants are awake for one minute, Dr. Kline plans to let them return to sleep. As they enter REM sleep again, he will wake them again and follow the same procedure. He plans to do this through the entire eight-hour sleep session. The following morning, participants will be asked to take a simple SAT test. Dr. Kline asks his participants to provide informed consent. Doing this is adhering to which principle of the Belmont Report? A) The principle of beneficence B) The principle of justice C) The principle of integrity D) The principle of respect for persons

He plans to do this through the entire eight-hour sleep session. The following morning, participants will be asked to take a simple SAT test. Dr. Kline is deciding whether he needs to give his participants a reason for waking them up several times during the night. He knows that he cannot tell them the real reason, but he is unsure whether he should deceive them or provide them with no cover story at all. Which of the following issues should be considered most heavily when deciding whether or not to use deception? A) Whether his IRB will approve the use of deception B) Whether he can create a convincing story that his participants will believe C) Whether he can conduct the study just as well without deception D) Whether his participants will be angry when they find out he used deception
question
D) Participants must be told the nature of the deception and the reasons for it
answer
Dr. Kline is planning on conducting a study next semester. He is curious as to whether sleep deprivation is associated with poorer cognitive performance. For example, if you sleep poorly the night before a big exam, will you do worse? Dr. Kline is especially curious about selective sleep deprivation, where people are kept from entering REM sleep. Using an electroencephalograph (EEG) to monitor brain waves, he plans to let participants sleep until they enter REM sleep then he will wake them. After the participants are awake for one minute, Dr. Kline plans to let them return to sleep. As they enter REM sleep again, he will wake them again and follow the same procedure. He plans to do this through the entire eight-hour sleep session. The following morning, participants will be asked to take a simple SAT test. Dr. Kline plants to use deception in his study and is thinking about a debriefing session. Which of the following is true of the debriefing? A) Dr. Kline only needs to invite participants who were troubled by the study of a debriefing session B) Because his study has potential medical applications, the use of a debriefing session is optional C) During the debriefing, Dr. Kline only needs to tell the participants that there was deception D) Participants must be told the nature of the deception and the reasons for it
question
A) Data fabrication

question
A) Validity
answer
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. If Dr. Sheffield's measure does not actually measure pathological gambling, his measure is said to lack which of the following? A) Validity B) Reliability C) Conceptualization D) Operationalization
question
C) Criterion validity
answer
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) Criterion validity D) Discriminant validity
question
B) Two months later, ask the same group of people to report how many times they have gambled recently

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. Dr. Sheffield decides to test the criterion validity of his measure. Dr. Sheffield gives his measures to a group of people that includes suspected problem gamblers and non gamblers. Which of the following options below does he also need to do to get evidence for criterion validity? A) Give the measure to a group of people attending Gamblers Anonymous meetings B) Two months later, ask the same group of people to report how many times they have gambled recently C) Ask the participants to give their opinion on whether the measure is valid D) Give a measure of alcohol addiction to the same group of clients
question
C) Convergent validity
answer
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. Dr. Sheffield has now decided that he wants to test his measure on some university students ( who some estimates say have 6% prevalence rate of compulsive gambling). He has a group of 100 university students complete his measure. He also has them complete two other measures (one that measures addictive behavior in general and one that measures general attitudes toward gambling) He finds that his new measure is positively associated with each of these other measures. This procedure has provided evidence for the _______________ of Dr. Sheffield's measure A) Content validity B) Predictive validity C) Convergent validity D) Discriminant validity
question
B) He finds that the measure of gambling is not correlated with a measure of life satisfaction in the same two groups of people
answer
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. Dr. Sheffield has decided to test the discriminant validity of his new measure. He has a group of first-time gamblers anonymous (GA) attendants complete his measure and finds that they score higher than a group of people who do not attend the group. Which of the following results would provide evidence for discriminant validity? A) He finds that the GA attendees score higher on his measure than the non-GA attendees B) He finds that the measure of gambling is not correlated with a measure of life satisfaction in the same two groups of people C) He finds that more recent GA joiners score higher than veteran GA attendees, who are more recovered D) He finds that the measure he used is also associated with people's past diagnoses of pathological gambling
