This is the conclusion of a paper published online November 12 in Developmental Science. Here, the researchers ofund that it seems that the brain circuits used to simplify the visual perception by using as much context as possible (and they are responsible for most of the optical illusions) are not set before at least the age of 10. Before that most children have difficulties perceiving what we adults describe as optical illusions.
For once, there is a game for grown-ups only, and it does not involve dirty tricks. Just tricks.
