Remember two or six coloured squares, then pick the colour of a marked position on a colour wheel
This is a solo practice run: your results stay in this browser tab and are never sent anywhere. To contribute to a class result, join a live session with a code instead.
This task is new to Classperiment and has not yet been fully tested. Issues may occur in the procedure or scoring. The expected effect may also fail to appear reliably.
Task time: about 4.5 min
Remember the colours and their positions. After a short pause, one position is highlighted. On the colour wheel, choose the colour that was there as precisely as you can, and confirm your choice. Accuracy matters more than speed. You have up to 8 seconds for this.
First you try out the colour wheel, then you practise 6 times. In a classroom session, the explanation and results appear after the instructor releases them.
