Deci and Ryan (1985, 2001) have proposed that there are three fundamental needs that are required for human growth and fulfillment: relatedness, autonomy, and competence. Susan predicts that students who have these needs met in their psychology class feel happier and more satisfied with the class. She collects data and finds that students who feel more related and competent do feel happier but that feeling more autonomous does not seem to matter. Susan thinks that maybe autonomy is only necessary when people are in situations in which they are not being evaluated. Susan's prediction that students who have all three needs met will experience greater satisfaction with their psychology class is an example of which of the following?
A hypothesis
Which of the following is an example of translational research?
A neuroscientist utilizing the findings from animal research studying Parkinson's disease and determining if the findings are applicable to humans
Which of the following is an example of being a producer of research?
A researcher who generates their own hypotheses and conducts experiments to test them
Which of the following is an example of being a consumer of research?
A student who reads their psychology textbook

Dr. Kushner 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. Kushner is especially curious about selective sleep deprivation, where people are kept from entering REM (rapid eye movement) sleep. Using an electroencephalograph (EEG) to monitor brain waves, he plans to let participants sleep until they enter REM sleep and then wake them. After the participants are awake for one minute, Dr. Kushner 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 sample SAT test. Imagine that Dr. Kushner is a clinical psychologist who volunteers his time at a local prison counseling several inmates. Because of his connections there, he is considering using prisoners as his participants. Why is this choice potentially problematic?
According to the Belmont Report, prisoners are entitled to special protection.
Which of the following is an example of basic research?
An experimental psychologist who examines the function of a specific brain region
Which of the following has been used as a defense of animal research by animal researchers?
Animal research has resulted in many benefits to both animals and humans.
In looking at a scatterplot of interrater reliability, why would a researcher want to see all the dots close to the line of agreement?
Because it indicates that the researcher's two research assistants/raters are making similar measurements
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 makes Dr. Kang's study an experiment?
Dr. Kang manipulated one variable and measured another.
__________ is the approach of collecting data and using it to develop, support, and/or challenge a theory.
Empiricism
What does it mean that behavioral research is probabilistic?
Findings are expected to explain a certain proportion of cases. Not all cases all of the time.
Stefan wants to make a causal claim in his dissertation. Which of the following is necessary?

You and your friends go to see a speaker on campus. The speaker, Dr. Darian, is an "expert" on getting into graduate school. Which of the following should make you less skeptical about his advice?
His recommendations are based on a research review conducted by members of graduate admissions committees.
When is it acceptable for a researcher to study only participants from a specific group, such as a researcher studying depression in a sample of Native American women?
If the specific group being studied is especially prone to the problem being studied (e.g., if depression rates are higher in Native American women)
Which of the following is NOT an example of physiological measurement?
Number of panic attacks a patient reports
When conducting animal research, which guideline states that alternatives to animal research should be considered?
Replacement
In considering whether research is ethical, which of the following are balanced against each other?
Risk to participants versus value of the knowledge gained
Angela reads about a study in which cell phone use is associated with migraine headaches. She says, "Well, that study is not valid because I use a cell phone more than anyone I know and I never get migraines." Based on her comment, Angela may be forgetting which of the following?
Science is probabilistic.
For her research methods class, Serena plans to have several teachers complete a questionnaire about their attitude toward teaching children who have attention-deficit/hyperactivity disorder (ADHD). This is an example of what type of measurement?
Self-report measurement
Which of the following is true of variables?
Some variables can be either manipulated or measured.
Edward believes that there are a lot of differences between men and women on a variety of different dimensions. He believes this because when he thinks about books that have been written on men and women, he can quickly recall only books that say men and women are different (e.g., Men Are from Mars, Women Are from Venus) and cannot recall any that say men and women are the same. His reliance on what comes to mind is an example of which of the following?
The availability heuristic
Deci and Ryan (1985, 2001) have proposed that there are three fundamental needs that are required for human growth and fulfillment: relatedness, autonomy, and competence. Susan predicts that students who have these needs met in their psychology class feel happier and more satisfied with the class. She collects data and finds that students who feel more related and competent do feel happier but that feeling more autonomous does not seem to matter. Susan thinks that maybe autonomy is only necessary when people are in situations in which they are not being evaluated. Data collection and analysis was supervised by an experienced professor. Susan's hypothesis was not completely supported by her data. What does this mean?
The hypothesis and/or theory may need to be amended.
