Reaction Time Lab Report

Measurement of Reaction Time According to the Merriam-Webster Dictionary, reaction time is the time elapsing between the beginning of the application of a stimulus and the beginning of an organism's reaction to it. In the lab that was conducted, the reaction time of the muscular and nervous system was tested. In the muscular system, specific thenar muscles such as the adductor pollicis brevis, abductor pollicis, opponens pollicis, and the interosseous were involved and tested to cause opposition of the thumb. This was done in compliance with a Reaction Time Ruler, which is credible and accurate when used properly. The ruler is precise because in method, gravity is a constant. In other words, gravity as a variable never changes, because it moves at a constant rate of 9.8 meters per second squared. The rate of gravity also accounts for the acceleration of the ruler. The function of the hand and the aspects of the Reaction Time Ruler were the main elements in the tested …show more content…
This process was done by holding ice in the hand being tested for thirty seconds each try. Constricting the blood vessels needed to completed before each trial, then the mentioned steps would follow. This method is similar to the method of muscle fatigue, except this procedure involved ice and blood vessels. The third variable experimented was blood restriction. This method was conducted by restricting, or inhibiting, blood flow in the arm whose hand was being tested. The procedure was done by tying a band around the brachial region of the arm. The specified steps mentioned previously would be completed when Student B would feel numbness or a distinct feeling in his or her hand. Furthermore, the chosen variable tested was distraction. This was done by completing the procedure aforementioned. However, what is unique about this method is the implementation of listening to music. To do this, the student would listen to music using both
