Does Noise Affect Hand Eye Coordination

Does Noise affect Hand-Eye Coordination?
By: Sachin Sayal
Research Question and Challenge
Does noise affect hand- eye coordination?
This project is about if noise affects your coordination. I will be testing the answer to this question in both adolescents and adults. This experiment will test if people can concentrate or can maintain attention in a noisy environment. I chose this topic because concentration is something that is very important, and I hope that with this project I can prove that people can still do anything properly with noise in the background.
I think noise will negatively affect coordination for both activities and age groups. The reason I say this is because noise has the ability to make one unfocused and that lack of focus can affect completion of the task. However, I think that the effect will be less prominent in adolescents than it will be in adults. The reason I say this, is because adolescents are usually less bothered by noise and distraction, so I am hypothesizing that they will take the least time to do the tests.
– The presence of loud music
- The time it takes to thread the needle and the distance of the putt
- the length of the putter, the environment around the test subjects, and the needle and thread
1) Put together two hand-eye coordination tests to give to your test subjects in each environment.
2) Recruit approximately 10 adolescents and 10 adults test subjects. Test the test subjects in the quiet room first and then test them in the loud room after.
3) In the quiet environment, ask 10 adult test subjects to thread a needle 10 times.
4) Record the average time it takes for each test subject to thread the needle.
5) In the quiet environment, ask 10 adolescents subjects to putt a golf ball, so it could hit a bottle. Start at 3 feet away, and move back 1 foot until the participant misses the bottle.
6) Record the distance at which each participant misses the bottle.
7) Repeat step 3 with the 10 adult test subjects, this time with loud music playing.
8) Repeat step 5., with the 10 adolescence test subjects, this time with loud music playing.
9) Analyze results. Compare test subjects’ performances in the quiet and loud environments.
Approximately 20 test subjects
1 small room
Notebook for analyzing results
The purpose of this project is to help individuals understand when coordination is at its best, and what can inhibit it. It is also relevant to general life because it can help you do better in sports, music, art, and homework. For example, if music helps you concentrate while you are doing your homework, it might be better to do homework while listening to music so you could complete it faster and more efficiently.

For this project I had sources of error, for both activities.
One source of error for this activity was the amount of practice the test subject had. For example I tested my mom and dad for this activity. My dad hasn't done anything like this before, but my mom sometimes sews, so she had some practice of threading a needle. Another source of error was that they might have been used to doing the task when doing it the second time (in a loud environment), which could be a source of bias for my test results. Even though I took a brake of 15 minutes per test, there is still a possibility that they might have gotten used to doing the activity.
I had two sources of error for the adolescent results. One of them was the size of the putter (Medium height). I tested some tall and short test subjects, while some of the short test subjects had a hard time holding the putter because it was too long. Another source of error was if the test subject played golf before. A couple of test subjects played golf, so they had knowledge of how to use the putter and angle to hit so it could hit the bottle.
In conclusion my hypothesis was wrong because I thought for both activities that noise in the background will make it longer for the test subjects to complete their task, but it actually took them less time. The reason I thought this, is because noise usually distracts people and makes it longer for someone to complete a task. Overall the noise positively affected the results.
As you can see from my results, noise can help you finish an activity faster than without noise. This can relate to the world by helping you complete a task faster and more efficiently. Therefore, my hypothesis was incorrect, as I thought that noise will make you more distracted, causing you to complete a task slower. However, it was actually the other way around. My project proved that you could do your homework while listening to music, you could be talking to someone and doing an activity, without slowing you down. This project proved the theory, 'that noise distracts you' wrong.
The auditory cortex is the part of your brain that reacts to sound. The neurons close to auditory cortex respond to low frequencies and on the other end it responds to higher frequencies. I played songs that have low frequencies causing the neurons to react in the auditory cortex. There may also be neural connections in the brain between the auditory cortex and the frontal cortex that is responsible for concentration, explaining my study results.
