Quizplus · Accepted Answer

The experiment provides the best way of assessing whether cigarette smoking boosts mental alertness because it allows for manipulation of variables and control over extraneous variables, which helps to establish cause-and-effect relationships. A randomized controlled experiment can be designed to compare the cognitive performance of two groups, one of which smokes cigarettes and one that does not. The cognitive performance can be assessed using standardized measures before and after smoking or not smoking. This allows for the determination of whether cigarette smoking causes a change in cognitive performance.
