Question 1A recent study of informed consent forms showed that:

 

                most research participants don’t receive them.

                Facebook users don’t always know they are being studied.

 

                research projects have not been approved by universities where they are conducted.

 

                it is unethical to observe public behavior.

Question 7A researcher is studying cheating with online students.  She randomly places her students into 3 groups and administers an abnormal psychology test.  One group takes their test using paper and pencil in a supervised setting.  Another group takes their test on computers in the Harper College lab with security cameras in place.  The third group takes their tests on their home computer with no security measures in place. She then compares the number of minutes each group used to complete the test.  What is the dependent variable in the study?

 

                the time it took to take the test.

 

                the setting used to take the test.

Question 8If weight and fast food are positively correlated, we know that:

 

                fast food causes people to gain weight.

 

                weight gain occurs because of fast food intake

 

                the less fast food one eats, the less they weigh.

 

                the more fast food one eats, the more stress they feel.

 

Question 9If the correlation between severity of depression and age is  +.75, it means that:

 

                older people have more severe depression.

 

                older people have less severe depression.

 

                the older you are, the more depression you feel.

 

                there is no consistent relationship between age and severity of depression.

                Triple-blind effect.

 

                Buffalo Creek effect.

 

                Quasi-experimental design.

 

Question 12A researcher was studying the effects of Ipad use upon sleep.  She randomly assigned her subjects to one of two groups: Group A and Group B.  Group A was told to watch a video on a traditional television set.  Group B was told to watch the same video using their Ipad .  Then the researcher conducted a sleep EEG for 8 hours.  What is the independent variable in the study?

 

                the results of the sleep study

 

                the television

 

                the Ipad

 

                the video

 

Question 13The total number of cases of a disorder in a population over a specific period of time is called the:

 

                risk.

 

                incidence.

 

                prevalence.

 

                rate of occurrence.

 

Question 14Which of the following is an example of a case study?

 

                A study involving the use of a control group.

 

                An in-depth study of a clinical client’s life and psychological problems.

 

                A study of all of the cases of a disorder in a community.

 

                The creation of a disorder in a group of lab rats.

 

Question 15In a study designed to determine the effects of physical activity on memory consolidation, college students were randomly divided into 2 groups and then asked to take a memory test. After the memory test, the experimental group was asked to run on a treadmill for 30 minutes.   The control group was asked to watch a 30 minute video about risk-taking behavior.  At the completion of the 30 minutes, both groups were again given the memory test.  Which of the following was the independent variable in this study?

 

                the physical activity

 

                the 30 minute video

 

                the risk-taking behavior

 

                the memory test

 

Question 16All of the following are merits of the correlational method except:

 

                it can be replicated.

 

                it can be analyzed statistically.

 

                the results can be generalized.

 

                the study provides individual information.

 

 

 

 

 

Question 17To accomplish random assignment, one could assign participants to groups by:

 

                placing all the participants who share an important characteristic in the same group.

 

                making sure there is only one participant in each group.

 

                flipping a coin.

 

                asking participants to choose the group they prefer.
