Reaction Time and Coordination Laboratory Purpose: To study the brain's ability to handle different types of activities. Background: The primary motor area controls individual muscles. Most neurons in this primary motor area control areas of the body with the finest motor control, including the hands. The cerebellum at the neck coordinates muscular movements, in this case hand-eye coordination. The cerebellum provides the precise timing of skeletal muscle activity and controls our balance. The cerebellum can be likened to an autopilot constantly comparing the brain's intentions to the body's actual performance by monitoring body position and tension in various parts of the body. In this laboratory, the most important factor we use is the sense of sight, for which the occipital lobe is responsible. The occipital lobe is in charge of your vision and object recognition. Hypothesis: If tasks 1-4 are completed, then Alexis will be the person with the least amount of time because she is a cheerleader, so we expect her to have a good hand. - eye coordination. If task 5 is being performed, then Madison will be the person with the least amount of time because she seems to be better at coordination than the rest of the group members. Task 1 vs. Task 2: If task 1 and task 2 are running, then task 1 will take longer than task 2 because we can recognize the color and move faster accordingly. Task 1 vs. Task 3: If task 1 and task 3 are running, then task 1 will have a shorter time than task 3 because sorting cards randomly into two piles is easier than sorting cards randomly in four piles. Task 4: If task 1 and task 4 are running, then task 1 will be... middle of paper ...... time 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 different parts of the brain. We used the occipital lobe, the primary motor area of ​​the frontal lobe and the 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 colors, shapes, and hand-eye coordination. Sources of error: • I forgot to mix or it was done in a hurry. • The timer was stopped for a moment. a few seconds after the person finishes mixing.
