How well do you know yourself? For instance, are you the type of person who's easily distracted? Or, are you so good at concentrating that you can tune out all the distractions around you?
Take this test to find out. Look at the two blocks of five rows and six columns of Q's. Can you find the O in each block? Take the test now.
So, did you find the O's? Or, were you distracted by the cartoon character on the right?
Your answer will put you, and everyone else, on the spectrum for being distractible, according to a professor at the University College London. She says that includes attention deficit hyperactivity disorder (ADHD) on the far end of that spectrum.
