Why can’t you draw a square with one hand and a circle with the other at the same time?
Bob Dylan can sing and strum. Brett Favre can (usually) run and throw. So why is it so hard to rub your tummy and pat your head, or draw a circle and a square simultaneously? David Rosenbaum, a professor of psychology at Penn State, says this is “a fundamental question: Why is it difficult to \carry out two different movements at the same time? The joke says you can’t walk and chew gum. You can do that, but there are certain pairs of activities that we can’t do very well, like drawing a square and a circle.”
