The Necker Cube and Human Perception

The Necker Cube is an ambiguous line drawing. It can be interpreted two different ways. When a person stares at the picture, it will often seem to flip back and forth between the two valid interpretations. The Necker Cube is an optical illusion first published in 1832 by Swiss crystallographer Louis Albert Necker.

Like the paradox of the “half-empty/half-full glass of water” the Necker Cube shows how human perception is multi-stable. It can change and be changed–it can flip/flop.

This also shows why the cvs2bvs brain software is so powerful in the human perception system because it can change, or flip, perception from one stable state to another stable state–on command!

  1. The question is why the human brain ‘holds’ perception as a collection of stable states rather than a fluid sequence of simultaneous possibilities. This seems to be a limitation akin to four dimensional thinking. Perhaps training can get us to the point where something can be seen to be many things at precisely the same moment, such that all of the possibilities co-exist multi-dimensionally.

  2. I think that is what perception means — you see what you want to see, you take the direction where you want to go. And, that is what makes cvs2bvs easy because the perception becomes clearer and change is easy .

  3. some time ago I heard an intervue on the bbc science programme where the speaker said if some one wore a pair of special glasses that turned everything up side down after several hours the person would become physically sick and be unable to co ordinate or walk but if the person could persivere for 2-3 days the brain would compensate and turn everything the right way up
    THE POWER OF THE BRAIN I will remember the intervue for ever
