scientists from thep AAAS meeting in Washington DC, showed that some monkeys trained to play a game with a computer to chose between 3 options, they feel the self-doubt and uncertainty as humans feel.

that game showed to the monkey( the old world monkey from europa) a box that appeared at the top of the screen and they have to choose with the cursor if it was dense (d) or sparse (s); if they chose the right answer they got an edible treat, if they dont, they didnt get a treat and the game stopped for a moment.

Later, there was another option: a question! they could choose a question mark, and it showed us that the dude is from de humans and monkys too, and they can "pass" a step like us.

this study was developed for "old world monkeys", the scientists wanted to make the same process to "new world monkys" but it wasn`t possible.
