A researcher wants to test the effect of alcohol on driving performance. Participants first drive through an obstacle course bef
ore drinking any alcohol. The participants then drink 8 ounces of alcohol and drive the course again. After each trial, the number of traffic cones hit is recorded. The researcher finds that the number of traffic cones hit is greater before rather than after the participants drank the alcohol. What may best account for the change in performance?
