Neuron Behavior
Kaitlin Cough, Elizabeth Harnett
Our hypothesis was that reaction time would be slower if you were distracted, and it did not matter how far the stimulus was from the brain: it would still react at the same time. We did four different experiments testing neuron behavior. Kaitlin and Elizabeth were both tested. Constant: we always poked on the hand, with exception of the foot trial.
Experiment 1: Poking the hand without any distraction.

We discovered that our first hypothesis was correct: if you were distracted, then the reaction time was much longer. This could especially be seen while we were talking on the phone. However, our second hypothesis was slightly disproven. We found that distance from the brain did have an effect on reaction time, even though the reaction time was not as slow as when we were distracted.
Our story: Don't talk on your cell phone when your driving!
Distance from the brain has a slight effect on reaction time, though nothing as drastic as distractions (reading, talking, etc.) Maybe a next step could have been to test the effect of music on reaction time, because usually when you are driving you are listening to music.
