Reaction Time & Coordination Lab Purpose: to study the ability of the brain to handle different kinds of activities. Background: The primary motor area is controls individual muscles. Most of the neurons in this primary motor area control body areas having the finest motor control including the hands. The cerebellum at the back of the neck coordinates muscle motion, in this case- hand- eye coordination. The cerebellum provides the precise timing for skeletal muscle activity and controls our balance and equilibrium. The cerebellum can be compared to an automatic pilot continuously comparing the brains intentions while actual body performance by monitoring body position and amount of tension in various body parts. In this lab, the most important factor we use is the sense of sight, which the occipital lobe is responsible for. The occipital lobe is in charge of your vision and object recognition. Hypothesis: If the tasks 1-4 are being completed, then Alexis will be the person with the smallest amount of time because she is a cheerleader so we expect her to have good hand- eye coordination. If task 5 is being completed, then Madison will be the person with the shortest amount of time because she seems to be better at coordination than the rest of the members of the group. Task 1 Vs. Task 2: If task 1 and task 2 are being completed, then task 1 will have a longer time than task 2 because we can recognize color and move faster accordingly. Task 1 Vs. Task 3: If task 1 and task 3 are being completed, then task 1 will have a shorter time than task 3 because sorting the cards randomly into two piles is easier than sorting the cards randomly into four piles. Task 1 Vs. Task 4:If task 1 and task 4 are being completed, then task 1 will ... ... middle of paper ... ...ge for task 3 was about 2.7 seconds less than our group average for task 1. By doing this lab, we were able to better understand the functions of the different parts of the brain. We used the occipital lobe, primary motor area in the frontal lobe, and cerebellum of the brain to complete the tasks required of us. These parts of the brain allowed us to sort cards based on our vision, being able to recognize color, shapes, and hand- eye coordination. Sources of error: • Forgot to shuffling or it was done in a hurry • The timer was stopped a few seconds after person was done shuffling. Works Cited Holland, Steven. "Talents in the Right Brain."
