At the opening symposium of the Donders Institute (Netherlands) last November, Victor Lamme showed a video that fully grasped the attention of the packed audience. It was a filmed experiment in psychology where people were being fooled by simple, even obvious tricks.
It introduced his discussion on the nature of consciousness and awareness, with difficult questions such as: can we say of someone who is not aware of what s/he perceives that s/he is still conscious? Or as Victor Lamme says it elsewhere: ‘In my research I want to separate becoming conscious of the outside world from the reporting on it’.
The talk was good, with Lamme suggesting a definition of consciousness that included functional and structural criteria of neural activity. However, at the very end a question from the floor completely destroyed his argument, when someone pointed that, according to the criteria developed in Lamme’s definition, neural activity during sleep would in fact also qualify for his proposed definition of consciousness – quite a problem !!
Anyway, I have found a similar video demonstrating how easy it is to trick conscious and fully aware people. It is less academic than the one presented by Lamme but it has the benefit of working on you, the viewer. So, will you be tricked? (please answer the anonymous poll thereafter).

That was very convincing!
And there was none yet who voted yes at the poll!
