In this experimental paradigm, you will view a rotating array of crosses.
In addition, in the middle, a small cross with a sinusoidal changing color appears.
Moreover, in a somewhat lateral-oblique position, a yellow dot will appear.
If you focus your sight on the central coloured-changing cross, the lateral-oblique yellow dot will sometime disappear from your awareness and sometimes re-appear.
You will be asked to report when the yellow dot disappears and when it re-appears by pressing one out of two buttons (one for the disappearance and one for re-appearance).
Finally, the block will be terminated, and a new block with the same stimulus will appear.
