Discuss Energy and attention span

research proposal on energy level and attention span. Coming up with a research that can be carried out and be tested. My topic is consumption of energy drinks/ caffeinated drink like coffee with give you a longer attention span than not drinking a caffeinated drink. Testing would be done with a baseline of participants not drinking a caffeinated drink and then taking the standard test and then consuming the caffeinated drink and taking the same test again. I hypothesis that if you consume a caffeinated beverage your attention span will be better than if you didn’t have a caffeinated beverage. Supporting evidence for my literature review
