Experiential Task #1
How does your body React to Stimulus?
Everything in your body is connected which means that when your muscles react to something they have to be prompted by another part of your body to react in the first place. The nerve endings in all over your body are what connects sensations to your muscles. A lot of times if your body couldn't feel something it wouldn't react the right way. For example if our nerves didn't register the cold outside then our body wouldn't shiver and it wouldn't warm itself up so our body would begin suffering. Stimulus is the actual thing that activates our nerves to make them fire neurons to move our body. So the neurons connect the nerves of our body to our muscles creating movement as a result of a stimulus.
Why does our body React to Stimulus?
Its our body's natural reaction to jump or move or in this case grab something when prompted to. We have nerves for a reason, to simply feel things and make the body react to them. This means that our body naturally begins a reactive response once something activates any of our nerves.
Why is this Important?
This is important because reaction to stimuli in a real life situation could mean the difference between life or death. When your body simply acts on a gut reaction then the person has a higher chance of surviving the situation. This means that usually our instincts are controlling our reactions based off of what they feel at any given time. A persons instincts are usually based on how often they have to react momentarily in a given situation.
In this test I will be testing the reaction time of my teammate Rachel Bean based on her visual, auditory, and sensational instincts to determine her ability to react to those sensations. Each test will be administered as seen below.

Visual Test
1. Subject one dangles dominant hand off the edge of a table.
2. Subject two holds a 30 centimeter (12-inch) ruler between two fingers at the 30 cm mark, having the 0 mark touching subject one’s index finger.
3. Subject two tells subject one to grab the ruler as fast as possible, when they SEE it being released.
4. Record the centimeter measurement.
5. Repeat this three times, for a total of four measurements
Auditory Test
1. Subject one is blindfolded before dangling dominant hand off the edge of a table.
2. Subject two holds a 30 centimeter (12-inch) ruler between two fingers at the 30 cm mark, having the 0 mark touching subject one’s index finger.
3. Subject two tells subject one to grab the ruler as fast as possible, when they HEAR the word “release” being said.
4. Subject two simultaneously says “release” and lets go of the ruler. Record the centimeter measurement.
5. Repeat this three times, for a total of four measurements
Tactile Test
1. Subject one is blindfolded before dangling dominant hand off the edge of a table.
2. Subject two holds a 30 centimeter (12-inch) ruler between two fingers at the 30 cm mark, having the 0 mark touching subject one’s index finger.
3. Subject two tells subject one to grab the ruler as fast as possible, when they FEEL their non-dominant shoulder being touched.
4. Subject two simultaneously touches the shoulder and lets go of the ruler. Record the centimeter measurement.
5. Repeat this three times, for a total of four measurements
Calculate the average centimeter number for each sensory measurement.
Use this chart to determine reaction time.

My and Relation:
This is something that I can relate to based on the fact that I've been an athlete my whole life. Reflexes and reaction are part of my daily routine when at practice and participating in PT, earlier in the school year I experienced a major injury to my left leg and now I have to constantly do physical therapy to get my reflexes back to how they should be. Its a difficult thing to do, you never realize how important your instincts and reflexes are until you lose that ability for a substantial amount of time. Getting that ability back takes countless time and effort and I'm still not 100% back to how I should be to be able to compete in an actual soccer game.
My Reaction:
Watching Rachel do the tests I think her reflexes were accurately tested based on these three tests. I think that her point about me being a reason for possibly not having accurate results was totally true because I could have touched her shoulder late or told her I released the ruler late. I think she did an awesome job during the experiment in being compliant and easy to work with.
