in my 40s, so you'd expect me to be slower than average. My display (Dell2410)'s input lag is 20-40ms
, so optimistically I could say I matched your 150ms number, once...
I'd expect faster numbers if you went from black to white. human's are less sensitive to color change than luminance - color flicker disappears above ~20hz, but for luminance it takes at least 60hz or for some folks even higher.
keep in mind that the scientific results are averages and don't necessarily represent the most motivated subjects. BUT they probably used ideal hardware, as in LEDs and microswitches. So their numbers are probably quite accurate - for the population and task.
People can move their eyes to a newly appeared target in ~70ms under the right circumstances. But hands are much slower than eyes.
