How many did you get?

How many passes did you count?

The correct answer is 16 passes….

Did you see the gorilla?



If not, go back and watch the video again but this time don’t count the passes, simply watch it like you are watching TV.

To go back: Click on the progress link on the top left hand side of the screen to open the course chapters, and go back to the ‘Brain Test – concentration’ section.  

The same video also appears again in the next chapter of the course, if you’d prefer to click forward rather than go back.
