Are the yellow dots disappearing?

Can you see the three yellow dots in the below picture? Well if you look a little more closely at the centre of the image they may just disappear:
If you focus for a few seconds on the green dot in the centre of the grid, the three yellow dots surrounding it will start to fade away and probably make you feel a little dizzy. If you focus away from the centre dot, the yellow dots will reappear.

Some research suggests it highlights a human visual processing failure which causes the peripheral objects to be temporarily eliminated from view; however others argue there is actually a useful reason for it.
