Decide which way the stripes were tilted.
Look at the dot in the middle. Then a striped pattern appears very briefly. Choose tilted left or tilted right. If you are unsure, choose a direction anyway. Answer as soon as the two answer buttons appear.
Use F for tilted left and J for tilted right, or tap or click the two buttons under the grey field.
First you practise 8 times with feedback. In a classroom session, the explanation and results appear after the instructor releases them.
