What could the researchers who conducted the study in experiment brief 5 have done to improve their design?
A) could have used a different treatment method on another group of people
with high blood pressure, comparing the blood pressures of the two groups
B) could have taken away partial compensation entitled to participants every time
their blood pressure started to rise
C) could have given no treatment to a group of people without high blood
pressure
D) could have given the treatment group no biofeedback
Question 2
Aside from a variety of ethical concerns which may be present in experiment brief number 7, what should researchers have done differently, in terms of their design, to see if threat of punishment actually has some effect on motor performance?
A) should have compared the two fear conditions to a control group who
should not receive threats of punishment prior to performance on the task
B) should have compared the a third fear condition, in which the threat would
have been 75 volts, a value in the middle of the other two fear conditions
C) should have actually shocked the 100 volt group for poor performance, while
allowing the 50 volt group to receive no consequences for poor performance
D) should have actually shocked the 50 volt group for poor performance, while
allowing the 100 volt group to receive no consequences for poor performance
