Reaction Time Definition: Reaction time is the speed at which the brain responds to a stimulus and formulates a response. This is vital in most sports. The most obvious example is responding to the gun at the start of a race, but another example is a goalkeeper saving a penalty. Importance: Sprinters need a fast reaction time so that they can react to the gun at the start of the race and begin moving as soon as they hear it. This gives them a better start and for such a short race every fraction of a second you lose is important. The start can alter the final outcome of the race, making reaction time a vital component of the sport. Speed Definition: Speed is moving any body part extremely fast. Speed isn't only the pace at which you move…
Fastest Reaction Time Problem or Question: Who has the fastest reaction time in our group? Hypothesis: If Maasilan, Tanveer and I are tested, I think I will have the fastest reaction time. This is because I have the biggest hands in the group, which makes it easier for me to grab the meter stick. I also have good reactions because I play lots of sports that involve catching or throwing. I also have good concentration and focus which helps so that when the person drops the stick, I know when to…
How does sight and hearing affect your reaction time? Introduction/Background: Many researchers have confirmed that the reaction time for sound is faster than reaction time for sight. Average reaction times for hearing being 140-160 milliseconds and a visual reaction time being 180-200 milliseconds. (Galton, 1899; Woodworth and Schlosberg, 1954). This is because an auditory stimulus only takes 8-10 milliseconds to reach the brain (Kemp et al., 1973) whilst a visual stimulus takes 20-40…
original question was “Will texting or talking affect reaction time more?”. The hypothesis is : If a meter stick is dropped and caught while texting or talking to test the subject’s reaction time, then texting will have more of a reaction time than talking. This test measures reaction time of texting and talking to know which of the two are more dangerous to multitask with. Texting uses three distractions of the brain, visual, cognitive, and manual while talking just uses manual and cognitive.…
performing a naming task which impacts reaction times. In the Stroop (1992) study found that color naming had a slower reaction time when the color words were printed in a different color, but even slower reaction time occurred when the color and word were completely separate from one another. The current experiment used Stroop task to determine the impacts of reaction times to test the hypothesis to see if there is a significant difference between the reaction times amongst the four levels of…
effects of caffeine on the reaction time of participants. Research surrounding caffeine is important to know the effects Caffeine affects the human body by increasing alertness and reduces fatigue as a result of stimulating the brain. In this experiment, the independent the amount of caffeine subjected to each individual in each group and the dependent variable was the reaction time tested and recorded for each person. There was 1 control group (group c) and 2 treatment group Treatment Group A…
of change in Reaction Time as age increases? As people increase in age, their reaction time can change as well, either increasing or decreasing. If kids in different age groups measure their reaction time using a test online, then the percentage of change in reaction time will increase with age. There are an abounding amount of things that can affect how fast or slow someones reaction test time is, along with what happens to your body when it is measured and the process of it all. Also, what…
Do you start your day with a fresh, steaming cup of coffee? Do you drink coffee to satisfy your addictive craze? Do you need caffeine to keep you awake? Caffeine is the most widely used drug in the world, consumed by some 80 percent of American adults every day. Caffeine generally improves alertness and reaction time, but evidence is inconclusive for its effect on higher memory and reasoning processes. Smith (2012) compared those who received caffeinated coffee had significantly faster simple…
Aim To investigate the effect of caffeine on the reaction time of humans. Key Words Caffeine, Reaction Time, Human body, cAMP, PDE, Summary This experiment involved measuring and recording the reaction time of test subjects before and after giving them a dose of caffeine in order to see the effect that caffeine has on the reaction times. Introduction Caffeine is a chemical compound with the formula C8H10N4O2. It is found in over 60 plants including the coffee, tea, cacao and kola plants. …
Results indicated that average reaction times for the auditory and visual stimuli tests were both significantly different from that of the control conditions (see table 1 and figures 1, 2 and 3). Differences in average reaction time differing from the control test (test 1) range from as little as 4 milliseconds (test 2, test subject 2) to that of 67 milliseconds (test 4, test subject 3) (see table 1 and figure 1, 2 and 1.3). According to the averages of the percent increase in reaction time, the…
