In a laboratory, smokers are asked to "drive" using a computerized driving simulator equipped with a stick shift and a gas pedal
The objective is to maximize the distance covered by driving as fast as possible on a winding road while avoiding rear-end collisions. Some of the participants smoke a real cigarette immediately before climbing into the driver's seat. Others smoke a fake cigarette without nicotine. You are interested in comparing how many collisions the two groups have. In this study, those who receive the cigarette without nicotine comprise the ___________ group.
a) control
b) extraneous
c) experimental
d) correlational
ANS: A, A control group gets either no treatment or treatment with no effect; in this case, experimenters are controlling for the possibility that the cigarette itself (not the nicotine) might cause people to get into collisions.
