Are you pretty sharp? Do you pride yourself on your Holmes-like powers of observation? Try watching the 'Bet You Can't Do This' video

Make sure you've got the sound on your computer turned on when you watch this video.

The explanation

You might be wondering how we hid a mouse in the video. The ruse was powered by something called inattentional blindness.

Inattentional blindness (also called perceptual blindness) is really just the academic term for something magicians rely on everyday – misdirection. But it’s of real interest to psychologists – in fact our clip is based on an original experiment carried out by Daniel Simons of the University of Illinois and another by Christopher Chabris of Harvard University. The question they were interested in trying to explore is just how much of what we see (or don’t see) is a result of our attention.

Small things can make a difference… so you might see that everyone is wearing clothes that are similar in colour to the mouse. Also we added a few red items to the scene to ensure the mouse’s belt didn’t stick out too much.

There are really important consequences to this sort of research. For example, psychologists play a key role in the design of things like road signs – just how do you ensure that drivers concentrating (hopefully) on the road will see things?

What could you do next?
