Instructions
    - In the Experiment you will see 2 avatars with different hat colors.
 
    - Whenever the sunglasses of either avatar change color, you need to perform a certain expression (more info on the next page).
 
    - Only the avatar whose sunglasses changed color, will also perform an expression. This expression is irrelevant for your task.
 
    - Perform the correct expression as fast as possible as soon as you see the glasses change color.
 
    - Hold your expression for a short time (~1 second) and then go back to a neutral expression until the next color change. You don't have to wait for the avatar to finish its expression.
 
    - The experiment is very fast-paced, so mistakes can happen. Should you perform an incorrect expression, just proceed as usual.
 
    - Please make sure you are performing each expression clearly. On the next pages you will get more information on how to do that.
