# Human Biology [Easy] Want to know your reaction time?

Discussion in 'Human Biology' started by JcMinJapan, Aug 31, 2004.

Have your friend hold a yard stick from the top so that it is up and down with the bottom several feet above the floor. Your friend may have to stand on a chair to do this.

You hold your fingers opposite the 18-inch mark, but don't touch the stick! Without warning your friend should let go of the yard stick, and you should try to catch it with your fingers.

Notice what inch mark your fingers are on when you catch the stick. Subtract this number from 18 or subtract 18 from the number to see how many inches the stick fell before you caught it. Try it several times to see if you get the same answer. Let your friend try to catch it while you drop it. Who has the quickest reaction time?

distance dropped reaction time
2 inches = 0.10 seconds
4 inches = 0.14 seconds
6 inches = 0.18 seconds
8 inches = 0.20 seconds
10 inches = 0.23 seconds
12 inches = 0.25 seconds
14 inches = 0.27 seconds
16 inches = 0.29 seconds
18 inches = 0.31 seconds

I did this one. The first time was .25, the next one was .14 and the last one was about .19 I guess. Quite fun and challenging. I must practice grasshopper! My goal is ti get it down to .10 or LESS!!!!! How did everyone else do?

Now here is the real question: Is reaction time something you can improve on, or is it just how fast your brain is hardwired?

good question. Should try this every day 5 times a day at the same times every day for one month. Record the results here. Then see if there is any improvement. Anyone up for the challenge? :D

I used to be able to catch flies in mid-air w/o killing them . Once I caught one between my index and second finger w/o injuring it.
