Nice test and good luck getting a response time of 0.1 seconds - unless if you cheat :P
ReplyDeleteIs that really possible both to cheat or to arrive at 0.1 seconds...
ReplyDeleteYes, it is! Now, first we need to recognize that the background change is a random variable. The trick is to click a little bit before when you think the background will change - don't wait until you see the background changing because the impulse traveling in your nevrous system is not that fast - about 8 m/s or so (correct me if I got this number wrong). So it takes time from your seeing until clicking. You can click a little bit before when you think the background will change and it works if it happens to change at that instant. It won't always work as the time of background changing is a random variable, but certainly it works sometimes and this way only some of your response time is recorded since you already started approaching the instant before background changes. :)
ReplyDeleteWhat do you think ?
Okay yes of course, but that's not organised cheating! It's like poker, you bet on it and try. Oh and by the way, the slowest nerve impulse is at 0.7 meters/second, the fastest being 120 meters/second when traveling through myelinated neurons. In this case, the neuron in the arm (not plural since in this case there must be around 3 neurons involved in this action [this requires an entire post...]) going through the spinal cord and then to the superior colliculus is in fact myelinated. Thus, the speed should be closer to 100 meters/second.
ReplyDeleteIt still makes a difference whether you bet smartly or just bet for the sake of betting. :P About the speeds, I thought the slowest are around 6-8 m/s while the fastest about 80 m/s but thanks for updating my numbers.
ReplyDeleteOh come on, bet smartly. That's pure chance and intuition. Although if I tell you that the maximum time of waiting is 20 seconds, then it might help betting "smartly". Also, maybe the numbers you have are the average slowest and the average fastest. I took my numbers from one source only so other studies or books might be inconsistent on that matter.
