Reaction PP

As many know, reaction time is a measure of how quickly an animal can react to a stimulus, this involves the time that your brain can process and take action. Three main stimulouses are visual, auditory, and tactile, tactile being a physical contact. The quickest reaction time of the three usually being tactile. A tactile stimulus this is the fastest is because we have many sensors all throughout our body which enable us to react faster when we receive a stimulus compared to auditory and visual which both require more processing done by the brain. An examply of this is when we place our hand on a hot stove and almost immediately rectract our hand before serious damage can be done. A tactile stimulant moves through the nerve at about 390 feet per second which is the reason why we are able to respond in such little time. Visual and auditory stimulous has a larger processing time than tactile because for each, you first need to recieve the stimulus and then the information has to be processed by the brain and differentiate between a danger stimulus or a regular stimulus. Reaction time is also influenced by many factors. Sleep could impact the reaction time of an individual. If an individual is not getting enough, their reaction time will decrease because their body is lacking awareness and energy needed for the reaction time. In contrast, stimulants such as caffeine or drugs that increase your alertness or heart rate will have the opposite of lack of sleep. These will increase your reaction time because it increases your alertness which makes you more susceptible to processing stimulus faster.
