What is a "hybrid" model?

I know pretty much nothing about the area, but I would have thought that
one-trial learning and the "Aha!" effect were different.  I learnt not to
stick my fingers in a power socket when I was a kid - and it only needed one
trial! - but I wouldn't have though this was an "Aha!" situation. (It was a
"Yow!" situation.)  This applies to animals other than people, I'm sure.  And
you can have the "Aha!" effect after many trials, as with Koehler's apes. In
fact I would have thought this is when you usually get it - after lots of
frustrating failures.  So one-trial learning is neither necessary nor
sufficient for the "Aha!" effect.

Isn't the "sudden learning problem" that, after a number of unsuccessful
trials or trials, the answer suddenly comes to us?

Best wishes
