Study shows that monkeys learn from mistakes,someone?  

Monkeys are able to learn from their mistakes and will take risks to potentially win better rewards when playing games according to a new study.
"this is the first evidence that monkeys ,like people ,have 'would -have ,could -have ,should-have 'thoughts ." said Ben Hayden,a researcher at the Duke University Medical Center and lead author of the study published in the journal Science.
Hayden and his team trained the monkeys to associate a green square on a computer screen with a " high value" reward and other colors with "low value " treats.
the monkeys then played a game similar to the game show "Let us make la deal" where they had to choose between eight identical white squares.
But someone make mistakes ,they do not learn from their mistakes.they think that they are right.
