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."

QMHP asked all the children to make a line and listen for instructions. IIHC prompted Mrs. Luna to explain to all children what the plan was. Step 1 was for each child to wash their hands. Step 2 was for the children to get a snack. Step 3, was for the children to get 30 to 45 minutes to play. Step 4 was for the children
1. Decide which students will work together in groups of four. Students will remain in the same groups for the entire lesson.
After reading and easily understanding the tasks given to them, Mason and Jonas began right away. Jonas, my competitive child was racing against the clock, trying to beat the allotted time that I had given them in an attempt to prove me wrong. Mason, my oldest son, was in no hurry to complete the task in the specific amount of time given, simply stating his tasks would be completed and the time didn’t matter since I didn’t specifically state that the time allotment was part of receiving the reward of $5. Upon realizing he was correct, I understood how important every detail must be when conducting a schedule for a business.
The left and right hemispheres of the brain are each divided into sections. Within each sections are lobes, controlling such processes as our visualization, our movement, and our personalities. For instance, the occipital lobe in the back of our brain is responsible for processing vision, and the frontal lobe behind our forehead controls cognition and personality. The lobes of the brain are split between the right and left hemispheres of the brain. This well-designed arrangement is for the lobes to function correctly, so the two hemispheres of the brain can communicate with one

The brain has many different parts to it which help one function through daily life; parts such as the cerebrum which controls voluntary movement and regulates functions such as thinking, speaking and the ability to recall information. The cerebellum controls the balance and coordination and finally the brain stem, which consists of the medulla oblongata and the spinal cord which controls all involuntary functions such as breathing, heart rate and blood pressure. The brain stem is also able to carry out these actions even when someone is asleep. To fully understand how crucial the brain is to survival one must understand the functions of the brain stem.
The human brain is one of, if not the most, complex objects in the known universe. For centuries scientists and researchers have been attempting to unlock the secrets and understand its inner functions, so far humans have discovered only a fraction of its astounding power and ability. This begs the question if such an ambiguous and subjective test could truly determine the intelligence of an individual although not knowing the full potential capabilities of the human brain. Despit...

In the article titled “Is Multitasking More Efficient?” researchers measured the productivity of multitasking by asking groups of participants to switch between different tasks that varied in complexity. The study showed that there was the obvious loss of time when the participants had to mentally switch to the other task, and it was also revealed that there was a greater lose in time when participates had to “switch between more complex tasks… that were relatively unfamiliar” (1). Multitasking is meant to be time saving, yet the initial action of just switching between two tasks has been prove to be counterproductive in itself when the tasks being performed are moderately challenging. Some attempts of multitasking “may actually take more time in the end” than just simply completing each individual task separately (2). Multitasking difficult tasks not only negatively affects the time spent trying to simultaneously complete more than one task, but it also affects the productivity and learning aspect of completing a task as well. In the article “Taking on Multitasking”, author Jerome Rekart explains how “dividing attention by multitasking impedes learning and performance in the short-term and… long term memory and retention” (1). Multitasking when in regards to performing cognitive tasks, which requires more of an intellectual process to complete, thus isn’t recommended for specific tasks that aren’t
Why do we to multitask? A lot of things factor into why we choose to multitask. The combination of busy lives and lack of time cause us to do whatever we can to get things done as quickly and efficiently as possible, even if that means attempting to do more than one task at a time. Tugend states, “Although doing many things at the same time… can be a way of making tasks more fun and energizing” (725). We may feel like multitasking makes tasks easier to accomplish, but in reality it doesn’t
Previous studies that have researched the functions of the cerebellum have focused on investigating individuals that have damage to their cerebellum, such as was the case with the Phineas Gage’s frontal lobe study that proved that the frontal lobe served an important role in personality and behavior. Recent studies have had the advantage of new technologies that could significantly aid in identifying whether or not the cerebellum plays a role in specific functions, these include functional imaging techniques such as fMRI and PET imaging, and these recent technological advances have paved the way for new studies that focus on brain region activation. This new method in researching the cerebellum has created new hypotheses for the functions of this crucial brain region, which include but are not limited to cognitive and perceptual functions as well as the already examined motor functions.
