In this experimental paradigm, you will view a flickering picture of a natural scene.
In the flickering picture, there is one item that disappears and re-appears.
You will have to identify this item in the picture and click on it with your mouse cursor.
You will have to identify this item as fast as possible.
Finally, a new flickering picture will be presented, and you will have again to identify a new flickering item.
Note that sometimes it might be easy to identify the flickering item and sometimes very hard.
The picture will be replaced if you do not identify the flickering item after one minute.
