I think the "only see 24 fps" is a pretty common urban-legend-esque piece of knowledge. As I recall it stems from a fairly simple experiment where you spin something (such as a fan, car wheel, whatever), and at some hertz it appears as though it's not actually spinning at all (accounting for the radial symmetry of the object in question, of course). Generally this is something like 24 hertz.
However, there are actually many factors involved in the eye's temporal sampling rate, including luminance, cromaticity, the region of the eye doing the sampling and a few others perhaps (temperature, maybe?). For example, I think peripheral vision has a significantly higher temporal sampling rate, meaning if you look at your monitor from out of the corner of your eye you may notice flickering, while looking at it straight on you may not.
Anyway, I'm not an expert on the subject, so I may be wrong about a few details. Anyone who knows more please correct me.
