= Affecting Reactions With Music =

Broad Question
Does listening to music affect your reflexes?

Specific Question
Does listening to Classical, Rock, or no music through headphones affect your reaction time?

[]

Independent Variable:
Type or lack of music

Dependent Variable:
Reaction (cm)

Variables That Need To Be Controlled:
Volume (of the music) Height of meter stick (when dropped) Time listening to music before the meter stick is dropped Songs

Hypothesis
I hypothesize that people will have the best reflexes without music, then with classical music, then rock music

Experimental Design
For my experiment I will be testing people’s reflexes while they are listening to different types of music. I will be doing my test mostly in the library before school, because it will be a place where I can gather people to test and I will have time to fully conduct the experiment. I am hoping to have at least fifteen – twenty people participating. I want plenty of data to give me a good idea of what affected the reflexes. I will be conducting the experiment but I hope to have someone helping record data and time the trials. I will do two tests for each type of music and two tests per person, without music to act as controls. While I am testing, I will record my data onto a data table I printed out. I plan on taking pictures of all the materials I use, I will also have a few pictures taken of certain parts of the process, such as someone grabbing the meter stick. I will be testing in the library so I can simply upload the pictures right from my camera. If that doesn’t work I will send them to my teacher.

Conclusion
<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">The purpose of the experiment was to find out if music affects reflexes. I had each person listen to music and catch a meter stick I dropped. They listened to each type of music twice, then took the test twice without music. The results of the experiment were (when averaged out) that people had the best reactions while listening to classical music(25.075 cm), and the worst reactions when not listening to music(28.475).

Discussion
<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">My hypothesis was that people would have the best reactions with no music and the worst with rock music. My results did not support my hypothesis. There is a relationship between the independent variable (music type) and the dependent variable [reaction (cm)]. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">The tests went really smoothly, because people were interested and wanted to take the test. It was easy to test and results were clear. If I could improve my experiment I would try more than three types of music to get more results. I would also want to see whether other types of music affected reactions too. An interesting future study might be testing different types of reactions with different types of music.
