Sensory Showdown: Reaction Time Lab
Names: Period:
Background Information:
Reflexes are designed to protect you. Things like blinking your eye, the size of your pupil changing when you step into a bright room, or pulling your hand back from a hot surface are all reflex actions. Reflexes don’t require higher brain activity. If you touch a hot surface, you will actually pull your hand back before your brain   recognizes the heat.
Reactions require higher brain function. Putting your foot on the brake of the car when the car in front of you slows or comes to a stop is an example of a reaction. You must first see the leading car’s brake lights; that information must be processed by your brain and a signal must be sent to the muscles of your back and legs. The signal not only tells you to step on the brake, but how hard to step on the brake.
Scientific Question:   Who has a faster reaction males or females?
1. Hypothesis: If the brain responds to visual stimuli by sending messages to the hand to grasp the ruler
