My son (3.5) seems to think that wrong answers are more interesting than right ones, especially if he gets a reaction. I notice it too when he's playing games on the iPad. He plays correctly for awhile, but then he wants to see what happens when he picks the wrong answer or does the wrong thing. He likes to explores all the possibilities, and doesn't care at all about being "right" or winning. I wonder sometimes if this will change once he starts school.
