A researcher wants to test the effect of alcohol on driving performance.Participants first drive through an obstacle course before 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.Surprisingly,the researcher finds that the number of traffic cones hit is greater before rather than after the participant drank the alcohol.What may best account for the change in performance?

The improvement in performance after the initial trial could be attributed to the testing effect, where participants become more skilled or familiar with the task (driving through the obstacle course) simply because they have already attempted it once, leading to better performance on subsequent trials, regardless of the alcohol consumption.
