90. A psychologist wanted to see if people are more prone to seek the company of others when anxious than when calm. He randomly assigned half of his subjects to an anxiety group and then told them that, as part of the study, they would receive electric shocks. He did not frighten the other group of subjects. Finally, he recorded how many subjects in each group chose to be "tested" in a group setting and how many chose to be "tested" alone. What was the independent variable in this study?
a. tendency to desire the company of others
b. level of shock
c. level of anxiety
d. the anxious group
Answer c % correct 54 a= 15 b= 22 c= 54 d= 9 r = .30
91. In an experiment, four groups of college students used different memorizing strategies to learn the material in one chapter of a textbook. Then each group was given the same multiple-choice test on the material. What was the dependent variable in this study?
a. the students' performance on the test
b. the four different groups
c. the four different memorizing strategies
d. manipulation of memorizing strategies
Answer a % correct 79 a= 79 b= 7 c= 9 d= 5 r = .58
92. A psychologist wanted to see if people are more prone to seek the company of others when anxious than when calm. He randomly assigned half of his subjects to an anxiety group and then told them that, as part of the study, they would receive electric shocks. He did not frighten the other group of subjects. Finally, he recorded how many subjects in each group chose to be "tested" in a group setting and how many chose to be "tested" alone. What was the dependent variable in this study?
a. the two groups
b. the level of anxiety
c. preference for being alone or in a group
d. manipulation of anxiety
Answer c % correct 77 a= 4 b= 10 c= 77 d= 10 r = .64
93. A psychologist wanted to see if people are more prone to seek the company of others when anxious than when calm. He randomly assigned half of his subjects to an anxiety group and then told them that, as part of the study, they would receive electric shocks. He did not frighten the other group of subjects. Finally, he recorded how many subjects in each group chose to be "tested" in a group setting and how many chose to be "tested" alone. In this study, the group that was NOT frightened would be called the ________ group.
a. experimental
b. control
c. placebo
d. test
Answer b % correct 90 a= 8 b= 90 c= 2 d= 0 r = .27
94. In an experiment, the group of subjects to which the experimental group is compared is called the:
a. comparison group.
b. standard group.
c. confederate group.
d. control group.
Answer d % correct 97 a= 2 b= 1 c= 0 d= 97 r = .21
95. In an experiment concerning the effect of auditory feedback on accuracy in writing computer programs, one group hears a computer-simulated voice say each character or symbol that they type in as they are writing their programs. The second group does not receive the auditory feedback as they type their program lines. This second group is the ________ group.
a. experimental
b. control
c. placebo
d. confederate
Answer b % correct 79 a= 16 b= 79 c= 3 d= 3 r = .25
96. Why is it essential that the experimental and control groups be treated identically in every respect but one?
a. so that the dependent variable can be accurately measured
b. so that the results will apply outside the laboratory setting.
c. so that if the behavior of the two groups differs, the difference can be credited to the one thing that distinguished the groups from one another.
d. so that if the behavior of the two groups differs, that difference can be used to establish a functional relationship between the independent and dependent variables.
