During this study, the total number of the participants will be evenly divided into two different groups, and both groups will be asked to solve two simple subtraction worksheets. The independent variable of this study is the participants, and the dependent variable is how fast and accurate the participants can solve each of these worksheets. In order to manipulate the independent variable, one group will be given chewing gum while they are solving the worksheets. By providing chewing gum to one group only, this study can help find out whether chewing gum can increase the problem solving speed and accuracy or not. After the participants have completed each of the two worksheets, the time that it took for the participants to complete the worksheet will be recorded on a sheet of paper. Finally, the worksheet will be graded for how many problems that have been correctly solved. The results will be analyzed in order to find out the effects that chewing gum has on the participants’ problem solving speed and accuracy. Apart from conducting this study within the classroom environment, it is also important to conduct it under different environments as well. By doing this, it is to ensure that whether the test environments and circumstances have effects upon the participants’ results or …show more content…
This is to produce the conclusion from this study, which indicates whether the chewing gum has any effects upon the participants’ problem solving speed. As for the result, the group which has been given the chewing gum during the testing outperformed the other group in terms of problem solving speed and accuracy. In order for briefly explain this, it is suggested that chewing gum does also cause an arousal - it helps wake the participants up (Onyper, 2011). This result exactly matched with the initial hypothesis of the research, and it proved to be highly accurate and valid. The average result from the group with chewing gum was 90 percent compared to the other group’s average result of 80 percent. The ten percent in the difference between the two groups’ average results clearly proved that there are advantages of chewing gum during the testing. In order to reinforce this finding, there has been a hypothesis extracted from an interview with Dr. Andrew Johnson, a psychology professor at Bournemouth University in Dorset, England, which states that when chewing gum, both the heart rate and blood flow are increased as more oxygen and glucose being delivered to the brain (Pooley,
