I dunno about that, I took a chemistry course in school and one of the exam questions was to calculate the FPS human eyes can see at. Then do the same for wolves. Humans do make a distintion at 24FPS. We can see above 24FPS, but the difference is marginal.
Below 24 FPS, the screen flickers. (For wolves & dogs it's 60FPS, that's why they rarely watch tv, it's always flickering)

Flickering is an other and even worst problem. You would so much notice it at 24 FPS that any TV refresh at least 50 or 60 times a second and it's still visible. That's what is 50Hz or 60hz on a television. On LCD it became better, but on CRT for your eye not being tired by flickering required 80 to 120hz. I think video projectors are at only 48hz with no visible flickering, but the room is dark. It really depends on technology, conditions, anyway there is no "24 fps" absolute value.
I think what you got as a course was just an over simplification or even a mistake. http://en.wikipedia.org/wiki/Flicker_%28screen%29

I'm telling you, as someone who's taken university level chemisty/bio, there is a 24 FPS value. Something to do with how our brain perceives data. I think what happens is below 24 FPS our eyes can percieve each individual frame, so below 24 FPS you see the switch in frames, and thus a flicker. Above 24 FPS you're no longer able to distinguish individual frames.
http://en.wikipedia.org/wiki/Frame_rate
Wikipedia is claiming a 10-12 unique FPS rate for human eyes, but I recall calculating it at 24.
So a great example would be flashing blue & yellow light in alternate frames. 24FPS and lower, that's going to give you a seizure. 24FPS and higher, it's going to start to look green. We can see the extra frame, but our brain can't process it fast enough, so it mushes the two images together and makes green.

What wikipedia is stating is the number of frame you can individually process. Like you can tell if you saw your uncle in a serie of 12 pictures displayed in 1 second. You calculated something a long time ago, but please understand that you are not really clear yourself if it was flickering, percieved motion smoothness, or how many picture human being can distinguish... or even something else.
Wikipedia page doesn't say that the threshold is 24 or 12 fps for a human to consider a movie or game smooth, and consequently it doesn't tell you an higher rate would not be smoother. It doesn't tell also you will not feel lag if you have to wait 40 millisecond (24 fps) or 83 ms (12 fps) for your command to be drawn on screen. And that was your point, 24 fps is just good and enough. But that's just not the case, the higher the better, and 60 fps is not a mandatory but makes perfectly sense to get a lot better responsiveness and a smoother motion. It is noticeable, you do feel a lag if something takes 40 ms to display.
