Here is a brief quiz to test your ability to correctly identify the emotion behind facial expressions. To take the quiz, click a numbered button below to view images of individuals. These images will change briefly to display an expression. After the expression has flashed click on the word that describes the expression you have identitied. If you were wrong, click on another word button until you are told you are right. After the expression has flashed, you can press the corresponding numeric key on your keyboard to hold the expression on the screen.
