I chose the article titled, “To Brake or Accelerate When the Light Turns Yellow?”, which begins to examine how the effects of stress differ between two age groups of younger and older participants. Specifically, how stress alters the decision making while operating a motor vehicle which is something most people do almost every day. These participants were asked to play a driving game in two conditions of either a controlled group setting or the experimental group setting that had to play after a stressful event. Both the young and older adults participated in 15 driving game trials, the experimental group had to stick their non-dominant hands in ice water and the control group had to put their hands inside warm water. To test the response of…
Basically deviation produces a negative response to counteract or nullify the deviation. it is a 'feeding back' of the disturbance to the status quo. due to the liver being part of the digestive system, as we know when blood glucose levels fall, the liver glycogen is converted into glucose in order to top up those crucial energy levels in cells. this is an example of a negative feedback…
The purpose of creating this scientific investigation was to see which type of shoe would kick a soccer ball the furthest. The hypothesis for this project was, “If the type of shoe affects the ball’s distance traveled when kicked, then the cleat will kick the ball the furthest.” The independent variable was the type of shoe. The dependent variable was the distance the ball traveled. The way the responding or dependent variable was measured was the distance the ball has traveled.…
Scientific Analysis Paper 02 – Designing Experiments Some might read the CNN article “Are music and happiness linked” and think that going to concerts regularly makes you a happier person, but it would be wrong to assume that without further scientific evidence. Instead of causation (one causing the other) it could be just a correlation (just happens to go together). Just as Dr. Weinberg mentioned in the article, maybe people that are happier tends to express their emotion through music and dancing. To find out if going to concerts regularly can really make you happier I would conduct an experiment, where I would monitor the happiness level of about three hundred people for over six weeks.…
My STEAM Expo experiment was testing which hamster food gives hamsters the most energy to hamsters. I tested three store brand foods: Carefresh Complete, Sunseed, and Nibble Rings. I also tested one that I made based off of the research that I did prior to the experiment. I thought that this project was perfect for my three hamsters, because they are all very tired and lazy. I also think that other people can use my type of food so that their hamsters can be energetic, too.…
How does playing video games affect your heart rate? If someone were to play a video game, then their heart rate would be higher than before they played the game. The independent variable was playing the video game, and the dependent variable was their heart rate after playing. Some control variables were the location, temperature, and game. The control group was the heart rate before playing the game, while the experimental group was the game.…
The results highlighted a correlation, but we are not quite sure if the results yielded a causation. The arithmetic mean for the control group is 29.048. This signifies that in 2 minutes, the average subject tested scored 29 out of a total 36 or an 80.68% percent accuracy. On the other hand, the average for the our experiment group, the subjects give gatorade, is 30.524 or an 84.78 percent accuracy. The results slightly improved for the experiment, but it is highly unlikely that this is due to the actual gatorade consumption.…
The person’s gender, weight, and amount they were given to eat could cause fluctuation in results. The study that was done did not show significant change in the blood pressure of the individuals that partook in it. The study was mainly conducted to see if there would be a decline in blood pressure of people who had high or slightly elevated blood pressure. It was conducted to prove whether or not dark chocolate could actually be a treatment for hypertension instead of having to take pills.…
Cognitive scientist from University of Rochester had the same idea. But instead They took 50 people for two groups and made oe group play sims 2 while another played Call of Duty 2. After making they made them play the games they were assigned for 50 hours. Their conclusion was that people who play first person shooter as in this experiment Call of Duty 2 increased their reaction speed by 25 percent unlike the people who played Sims 2 a puzzle game.…
1. The best question that I was asked about my presentation was "Why were people satisfied with life even though they had a high BMI?" In other research, they have concluded that people are not aware that they are obese and they think automatically that they are healthy. Other research have shown that most people are not educated about BMI and the different levels such as: underweight, healthy, risk at overweight, and overweight. 2.…
The control group was required to eat a piece of liquorice and measure their blood pressure. The experimental group was required to smoke a cigarette and then have their blood pressure measured. Once they completed these activities the results and data were collected and put into a Microsoft excel spread sheet for statistical comparison. Each group got analyzed in search for statistical significance as well as looking for R squared and the P…
The study of stress is very important to our fast-paced society where de-stressing and seeking calm has become a profession for some, and a task that feels impossible for others. There have been many studies done in the field of stress and the various potential causes in everyday life. One study done by Chen, Fang, & Fang shows the efficacy of aromatherapy in nurses that were experiencing high stress levels due to their demanding occupations (2013). In this study, nurses wore a small bottle of lavender essential oil on their chest and were asked to determine their stress levels both at the beginning and end of their shifts for the duration of the experiment. It was found that this type of olfactory stimulation reduced the normal stress symptoms…
Purpose: Does the heart rate of a student rise more when the student is resting or exercising? It would be obvious that yes, a student’s heart rate would probably rise if they are exercising rather than resting. The data that has been taken down and tested have proven that statement to be true. Background Research: The background research that I have found that besides the difference between exercising and resting, age also has to do with the heart’s rate.…
The data does not support my hypothesis for the sad movie. The average change in heart rate for each movie genre was an increase. As predicted, the horror movie had a very high average change in heart rate while the change in heart rate was lower for the comedy and the drama. The romantic movie had a much higher change in heart rate than expected, but the hypothesis was still supported. The prediction for the sad movie was that the subjects’ heart rates would decrease and create a negative mean change in heart rate.…
Why The Extensive Use Of Video Games Is Bad For Your Health There has been a lot of controversy about the effects video games can have on a person 's health. Many argue that they stimulate the brain and increase intelligence. But others point out the negative side effects that the majority of gamers choose to ignore. Though everyone may not visibly suffer from any problems, that doesn’t necessarily mean that they won’t eventually. A lot of these issues are permanent; few are temporary.…
