The Effect Of Reaction Time On The Brain

If the response time for this experiment by saying the word” now” falls between 100 and 200 milliseconds, I would conclude that

The participants used a standard deck of playing cards, which had 52 cards in four suits. Participants used cellular devices with 1 second

The reaction timer from Maths Is Fun (2014) is specific to three decimal places. The accuracy of the chosen source reduces the risk of statistical measures being slightly greater or less than they would be if only one or two decimal places were provided. Unlike other reaction timers that are available online, this particular source requires the subject to complete five trials before the mean is calculated. Undertaking multiple trials will be vital to this investigation because if the subject was to anticipate the event or have one delayed response, the trials that follow would reveal such errors, therefore increasing the reliability of the results.

To first understand the importance of the clinical reaction time test, the physiological pathways involved in reaction time must first be

Reflexes are the body's reaction something, reflexes are signals that are sent from your neurans to your brain and your brain processes the information then responds. To test if the difference between voluntary and involuntary effects the reaction time. In this lab the voluntary reaction time was the time between when the hammer hit the table and when the leg moved. The involuntary reaction time in this lab was the time between the time when the hammer hit the knee and the time where the leg moved.

After this activity, they were asked to do a “lexical decision task” (a standard approach for measuring unconscious responses) in which they were shown a series of words and nonwords in random order and had to press “C” if it was a real word or “N” if not. Half of the real words were related to autonomy (e.g., freedom, choice) and half were neutral (e.g., whisper, hammer). The key focus of the study was on how long it took people to press the button *(“response latency”) for each kind of real word, averaged over the many words of each type. The table below

This video is about The Behaving Brain; it explains how the brain and amnesia work. According to the video, neurons duties are to receive information from other cells, process this information, and transmitting it to the rest of the body. This is done by traveling through dendrites, to the soma, to the axon, to the terminal buttons. Constant nerve flow helps regulate our metabolism, temperature, and respiration. It also enables learning and the ability to comprehend. The brain is connected to the brain stem, which is connected to the cerebellum, which is connected to the limbic system. The limbic system is made up of the amygdala, hippocampus, hypothalamus, and thalamus. The cerebrum is the largest part of the brain, where things are

Ullsperger, Bylsma, and Botvinick (2005) investigated whether the findings of Mayr, Awh, and Laurey (2003) can be replicated and how much they can be shown across different task performances. Their specific study was motivated by a prior experiment where Gratton, Coles, and Donchin (1992) found that after an incompatible type trial reaction times were reduced and target processing occurred more frequently than flanker processing on the next trial. Botvinick, Braver, Barch, Carter, and Cohen (2001) believed that this follows the conflict monitoring hypothesis where incompatible trials involve a conflict with the response leading to greater top-down information processing (Botvinick, Nystrom, Fissell, Carter, & Cohen, 1999). However, Mayr et. al (2003) argued that the congruency sequence effect found by Gratton et al. (1992) was due to repetition priming because of stimulus repeats in a flanker task. This may have led to a faster reaction time with repeated trials. Mayr et al. (2003) used two experiments to present evidence for their argument. Both experiments failed to show the effect found by Gratton et al. (1992) when target and stimulus items did not repeat from trial to trial.

I have always had a passion and interest in working with the unknown. When I was in high school, I always made sure I was taking science classes that interested me, and would help me decide on what I wanted to major in college. I chose neuroscience as my major because it is a subject that continues to fascinate me. Neuroscience is the study of how the nervous system develops, its structure, and what it does. I want to focus on the brain and its impact on behavior and cognitive functions. I want to go into clinical neuroscience (looking at the disorders of the nervous system) or cognitive neuroscience, which studies the higher cognitive functions and underlying neural bases. With a neuroscience major, I would like to pursue a career in clinical research, do research for the National Institute of Health, work for the CDC and specialize in neurological disease, and/or run a clinical research project in another country. I want to pursue a career in one of these areas because I want to dedicate my knowledge, skills, and time to helping people and the world of science. I want my work to make a positive impact on society and be beneficial for the forthcoming generations. I want to help people and discover new things that will help those in need. I am motivated every day to continue working hard by realizing there are still more things to be discovered and that it could be done by me.

It was therefore hypothesised that the reaction times for global judgments would be faster than the reaction times of local judgments. It was also hypothesised that consistent stimuli would be faster than conflicting stimuli in the local tasks.

A replication of Task Switching Monsell 2003 experiment was done, which predicts a time cost when switching tasks. 18 participants had to complete 100 randomized trials, switching between task-repeat and task-switching trials. Reaction Times (RT) were recorded and reflected by experimenters, to determine that there is a time cost involved when switching tasks as opposed to repeating the same task.

The participants for this study were recruited from a Spring 2013 Experimental Psychology Undergraduate Course at Queens College, City University of New York. The research study was IRB approved and the participants for this study were not compensated. However, by remaining in the course, the students gave consent to participate in all studies. There were a total of 22 participants, 20 being females and two males. The participants consisted of 21 right-handed individuals and one left-handed. The mean age was 21.09 years, and the standard deviation for age was 1.02.

Reaction time is defined as: "…the amount of time between the occurrence of an event (such as a car pulling out into the road) and a person's response (hitting the brakes)."- http://epsych.msstate.edu/deliberate/SimpleRT/index.html?6yesLeft.html

In the essay it will include; how distractions can affect your reaction time. How the braking distance is affected by speed. What the design of a vehicle and road conditions, can have an impact on a pedestrian. How the speed affects the occupants, if the car were to collide with a rigid object. And what design features are being put in place to minimise fatalities in car accidents.

The reaction time (RT) of students was measured in the experiment to determine whether light or sound stimulus initiates a quicker response time. The question of whether or not RT was related to movement time (MT) was also challenged. Each student performed two test in random order; one testing the reaction time of a red light stimulus, or visual reaction time (VRT); and the other testing the reaction time of a “beeping” sound stimulus, or auditory reaction time (ART). The student completed the VRT trial by simply receiving the stimulus and pressing a button. The student placing and holding their hand on a button starts the ART trial. Once the student receives the stimulus (beep) they press the adjacent button as fast as they can. The ART trial does not only include the data of the RT, but also the data from the MT. Having previous knowledge that light travels faster than sound; one can predict that VRT is faster than ART. The prediction that MT is independent upon RT can be made with the thought that there are so many opposing variables that could affect the MT of an individual unrelated RT such as old age
