I would say neither, I WOULD say he has a better memory and a higher level of observation and capacity.
The monkey is not using intuition IMO ... if you saw the whole experiment you would think the monkey was using magic or intuition or something unexplainable as he can do it WITHOUT THE NUMBERS APPEARING ON THE SCREEN!
How? For a few of them I thought the machine was broken ... the numbers never came up .... but the monkey got it right ... how?
Then they slowed it down, the numbers come up faster than the human eye can detect (but not a monkey's) and he can see, scan, and remember quicker than we can physically see the numbers .... played at normal speed .... no numbers .... slow the film right down .... and there they are.
But to us ... that would look like intuition . Same with me ... (although I am not a monkey, people have variant reception and calculation levels -most of us know how amazing a human memory can be compared to the average - ) some people insist some stuff I do is intuition or magic .... but it isn't (well, SOME of it is ... but not all of it).
