The panel below will guide you through a series of five experiments. The instructions for each experiment are the same. The first experiment is easy. It is designed to help you understand the instructions.
In each experiment, there are two different types of leaves. On each trial, you will see one example of each leaf type. The computer has randomly selected one type of leaf. By clicking with the mouse on a leaf, you have to use trial and error learning to find out which leaf type the computer has chosen.
If you are RIGHT, you will see a tick - click again on this leaf to go to the next trial with two new leaves.
If you are WRONG, you will see a cross - click on the OTHER leaf (the right one) to go on to the next trial.
If you are not connected to the net or something goes wrong, the experiment will stop.
