Direct RT has the capability to show pictures at a VERY fast rate (so fast that the person watching doesn't even know they saw the picture). I use this for subliminal priming. I think that the laptop refresh rate isn't fast enough or something, b/c even when I tell Direct RT to show pictures at 15 milliseconds (when we shouldn't be able to see the picture flash), it actually shows it for a second.
What is the refresh rate requirement for showing pictures at under 50 milliseconds
