In this paper, I researched Gingko Biloba, originating from the topic,” The Ginkgo Biloba Experiment: Testing for Effectiveness.” Many studies reveal that ginkgo biloba can improve memory and thinking in people affected by Alzheimer's or vascular dementia. The experiment involved participants that were assigned to an experimental group, or a group of participants in a clinical study who receive the actual drug or treatment being studied, which in this case was Ginkgo Biloba. Other participants were assigned to a placebo control group and received a placebo, which is a fake substance, treatment, or procedure that has no known direct effects. It looks like the actual drug, which is also known as the independent variable. Both groups take their medication for six weeks. At the end of the six-week study, the test scores for both groups rose. Why did both test scores improve when one was a fake substance? Does Gingko Biloba really work? Based from what I know and have read about Ginkgo Biloba, there is no difference between the independent variable and the placebo. They work the same; both improve memory and other cognitive abilities. The results of this experiment showed that both test scores improved and researchers say that outcome is because each participant took a test twice to make sure it is accurate. The practice effect made the outcome of both the Ginkgo and placebos’ test scores improve. The practice effect is when the participants experience with the test, the practice they got by simply taking the mental ability test twice—is most likely the reason why both groups had improved test scores. It is good to take a test twice for good accuracy, but it also passes as practicing so each person knows what is on the test and can also improve their test taking skills even though it’s a mental ability test. Since they already know what is on the test, certain weak
