30 ms doesn't seem possible. Check the Human Benchmark for statistics, the fastest ones are around 100 ms: http://www.humanbenchmark.com/tests/reactiontime/stat

Maybe light delay was not randomized and people were just predicting when it'd light up? I remember this kind of trickery being used in Jeopardy to beat Watson.
Another example is the Olympic sprint, where any reaction under 100 ms is considered a false start (if I read correctly): http://www.condellpark.com/kd/reactiontime.htm http://www.condellpark.com/kd/reactiontime.htm
- pygy_ 16y ago100 ms is for an adult... The kids have smaller arms, hence shorter axons. Assuming that their conduction speed are similar to that of young adults, a shorter reaction time isn't surprising for young children. [1] for adults, they decline with age, I don't know how they evolve during development
- a-priori 16y agoYes, presumably there is a difference, but it's not that much. The axons that conduct motor signals to the skeletal muscles have a conductance speed of 80-120m/s [1]. In 70ms (100ms - 30ms), at 80m/s, such a signal would travel 5.6m. [1] http://en.wikipedia.org/wiki/Axon#Motor http://en.wikipedia.org/wiki/Axon#Motor
