- The following data show the pattern of results that was obtained in a study by Liguori and Robinson (2001) examining how different levels of alcohol and caffeine consumption influenced response time in a simulated driving test. The means show the average response time in milliseconds for different combinations of alcohol and caffeine. For these data:
- Is there a main effect for alcohol?
- Is there an interaction?
- Does caffeine improve response time (produce faster times) for people who have
- consumed alcohol?
- Does caffeine eliminate the effect of alcohol on response time?
