I searched for the paper about the monkey experiment a few years ago.
I came to the conclusion that it was false, myth.
Anybody got a trustworthy reference?
The first time I heard this was actually just in person from a trainer at work. He told this over like 10 minutes or even more as an engaging story. The monkeys went "Uuuuh banana!" each time. Until they didn't ;) That's essentially how it stuck in my mind. Through the Uuuuh banana! exclamation.
