Factors that Influence Reaction Time
Reaction time is a measure of time that elapses from the moment the brain receives electrical impulses from our sense organs, to the time it elicits a response to the situation. The efficiency of this neurological process can be enhanced or compromised; alcohol, drugs, stress, lack of sleep, and aging extend response time, while repeated practice at a task reduces reaction time. There are two types of reaction times: "Simple" and "choice" reaction time. Simple reaction time measures the time between when a stimulus is received by the brain and a response is made tresulting in movement, such as pulling your finger away from a hot stove. Choice reaction time measures the time between when the brain receives a stimulus and a decision of how to respond is made. Choice reaction time can be increased through repeated practice.
