Yeah, anything less than 100ms is referred to by that site as "preemptive," or "lucky." And for the most part, I agree, but I do not rule out the possibility of those instances being largely pre-conscious reactions.

I can tell you that those super low scores, like "50" or so were me "trusting," in the reaction and just letting it happen. It was not me spamming the button and getting lucky.

To elaborate, when you look at the color green there is a series of pre-conscious routines triggered. Your brain grabs all the relevant data pertaining the the environmental signal, examines the array of values, and then informs your consciousness which allows for the cognition of green, or; you being aware of green.

To put it in simpler terms; your brain perceives and processes green before you are aware that you are seeing green. You can absolutely react prior to conscious awareness. You do it every day, all day.

I'm using the perception of green as an example because it is directly relative to the reaction speed test, however, you can really use anything you are familiar with; tree, car, sign, word, name, whatever ...

I've done the test four or five times, typically averaging 140 - 165 ish. I'd say the number of "preemptive" scores is roughly 50/50 with the "don't click until you see green again" response.

If you're regularly getting a "don't click until you see green again" then you're guessing to some extent, whether consciously or not. There have been a bazillion studies on human reaction times, and what you're describing is regularly seen. Without any guessing, it's not possible for humans to respond much more quickly than 200ms.

Many researchers have confirmed that reaction to sound is faster than reaction to light, with mean auditory reaction times being 140-160 msec and visual reaction times being 180-200 msec (Galton, 1899; Woodworth and Schlosberg, 1954; Fieandt et al., 1956; Welford, 1980; Brebner and Welford, 1980). Perhaps this is because an auditory stimulus only takes 8-10 msec to reach the brain (Kemp et al., 1973), but a visual stimulus takes 20-40 msec (Marshall et al., 1943). Reaction time to touch is intermediate, at 155 msec (Robinson, 1934). Differences in reaction time between these types of stimuli persist whether the subject is asked to make a simple response or a complex response (Sanders, 1998, p. 114).

For about 120 years, the accepted figures for mean simple reaction times for college-age individuals have been about 190 ms (0.19 sec) for light stimuli and about 160 ms for sound stimuli (Galton, 1899; Fieandt et al., 1956; Welford, 1980; Brebner and Welford, 1980). However, Eckner et al. (2010) reported that the reaction times of NCAA football players averaged 0.203 sec when determined with a simple falling meter stick but 0.268 sec when measured with a computer. Reaction times measured at Clemson are usually closer to 0.268 sec for a simple visual stimulus.

175ms average. I was getting 158-162ms on the ones I was really foced on, but then I blink or something and get 210ms.

Average stuff - Make sure to put your eyes to the scree nas close as possible to reduce travel time of light into your eyes.
