Caffeine and Reaction Time Essay

1) Identify the Problem or QuestionHow does the inhalation of caffeine affect the reception time of the nervous system?2) Introduction end of the try To identify the whether or not caffeine increases or decreases the reception time of the nervous system.In our taste, we have decided to use all the cases which forget rill how fast a signal from our brain will be sent to our muscles in order to click the mouse when we see an object or directions on the screen. We know that the commonly used drug, caffeine, increases the heart rate, thus the increase in blood flow. The question in our experiment is, does the increase of blood flow, caused by caffeine, positively or negatively affects the reaction time that it takes to click the mouse the moment we see an approaching object.An early(a) underlying grammatical constituent we kindle psychoanalyze in our experiment is gender and age. Since we are using test subordinates whose ages and gender vary from 16 to 50 and from male to fem ale, we can roughly conclude whether or not age and gender affect reaction time. The reason we say roughly, is that the two factors, age and gender, are being tested in conjunction with the pulmonary tuberculosis of caffeine. We do not know if the consumption of caffeine and its effects vary for how old the person is and his or her gender.3) Research and Current IdeasIn past experiments, muckle have concluded that there is an inconsistency in results depending on the amount of caffeine consumed. Apparently, a half-cup of coffee had faster reaction time than the reaction times that were pull when the test subject matter drank a full cup of coffee. The person had concluded that too much caffeine could actually impair reaction time, except the right dosage could potentially increase reaction time.4) Predict a solution to the problem or an answer to the questionScientific Hypothesis The consumption of 12oz of ground coffee will speed up our reaction time. Using past experiments co nducted by other people, and the chemical compounds of caffeine and its affects on our body, we have drawn this venture.Dependent Variable Reaction timeIndependent Variable Condition of the test subject (Caffeine)The reaction time is the dependent variable, because the results depend on the check off of our subject. The condition of the test subject is the independent variable because we are changing the state of our test subject by increasing their caffeine levels.5) Design the experiment to be used to test your hypothesisMaterials* 4 tablespoons/24 of Maxwell house coffee blend* Computer/Internet* 4 test subject (2 16 year olds/ 2 middle aged adults, one of each gender) * Serendip softwareProcedure1) Complete a control experiment by conducting the serendip experiment while you are in your natural state for each test subject. 2) The site for the serendip activity is serendip.brynmawr.edu/bb/reaction/reaction.html 3) Make sure that each Case is through 10 times to ensure accuracy. 4) Click Results Summary and record the information given. 5) Have each test subject consume 12 oz (2 tablespoons) of the Maxwell theatre Coffee blend. 6) Wait five minutes before the test subject goes through the serendip reaction time activity again. 7) Repeat steps 1-3 for each test subject, except after he or she has consumed the coffee and waiting for a duration of 5 minutes before completing the serendip activity. 8) Record the results in a data table.6) Carry out the experiment seek Type Control sample Experiment w/ Caffeine ferment 219 +- 15 milliseconds 194+- 11 millisecondsThink, Act 270 +- 32 milliseconds 243 +- 28 milliseconds Read, Think, Act 394+- 74 milliseconds 364 +- 68 milliseconds Read, Think-Negate, Act 383+- 102 milliseconds 352 +- 64 milliseconds Jazmine Ortiz, 16, FemaleJazmine Ortiz, 16, FemaleDaniel Kim, 16, phallicDaniel Kim, 16, Male screen Type Control Experiment Experiment w/ CaffeineAct 210 +- 10 milliseconds 191+- 8 millisecondsThink, Act 267 +- 31 milliseconds 236 +- 25 milliseconds Read, Think, Act 381+- 74 milliseconds 344 +- 60 milliseconds Read, Think-Negate, Act 375+- 102 milliseconds 342 +- 58 milliseconds Test Type Control Experiment Experiment w/ CaffeineAct 384 +- 72 milliseconds 298+- 38 millisecondsThink, Act 340 +- 62 milliseconds 323 +- 50 milliseconds Read, Think, Act 422+- 124 milliseconds 414 +- 119 milliseconds Read,Think-Negate, Act 398+- 102 milliseconds 375 +- 102 milliseconds Test Type Control Experiment Experiment w/ CaffeineAct 372 +- 70 milliseconds 361+- 67 millisecondsThink, Act 321 +- 49 milliseconds 310 +- 46 milliseconds Read, Think, Act 398+- 76 milliseconds 391 +- 74 milliseconds Read, Think-Negate, Act 394+- 106 milliseconds 370 +- 68 milliseconds *The data shown are the averages of 10 trials that was calculated by the serendip program *The data shown are the averages of 10 trials that was calculated by the serendip program Keon Shim, 39, MaleKeon Shim, 39, MaleMi Ok Kim, 44, FemaleMi O k Kim, 44, Female7) Analyze the data and observations7) Cont.Analysis The results we received from the experiment were what we had suspected. For every test subject, the reaction times for every Case that were influenced by the coffees caffeine were quicker than the controlled reaction times. For example, Daniel Kim had a controlled Read, Think-Negate, Act average reaction time of 375+-102 milliseconds. When he consumed the 12 oz of coffee, his average reaction time decreased to 344+-60 milliseconds.It is quite apparent from the graphs that the average reaction time for every case for each test subject decreased when absorbing caffeine into their system. Test subjects also consumed the right amount of caffine, 160mg, which allowed the subject to shorten their reaction time, while the wrong dosage could impair it. We can also draw from the graphs the relation that the younger the test subjects are, the quicker their reaction time will be. Also, we can also conclude from the results t hat males tend to have a quicker reaction time than females (Daniels reaction times were faster than Jazmines, and Keons were faster than Mis).8) State the conclusionThe hypothesis was correct. The effects of caffeine shortened the reaction time in all of our test subjects.9) Summary ParagraphThe reason why we were able to correctly devise a hypothesis for the experiment was because of the prior knowledge we had of the drug, caffeine. Caffeine increases the heart rate, which allows for faster muscle contractions. Caffeine does not really affect the actual reaction of the nervous system, simply rather the actual contractions of the muscles themselves. This known fact of caffeine is reflected in the experiment. It shortened the reaction time of our test subjects in every case. We found other factors in our experiment that may have affected the reaction time of our test subjects. A few scientists have theorized that gender can affect reaction time.They say that males tend to have a fa ster reaction time because males are usually involved in more physical activities, such as sports, which helps improve reaction time. That theory is also reflected in our results. All the male subjects had faster reaction times than their age equivalent female subjects. Finally, the last factor would be the age of the test subject. Our younger test subjects both had faster reaction times than both the older test subjects. There are some theories being circulated that once someone enters their mid-twenties, their reaction time slowly increases.
