THE BRAIN FROM TOP TO BOTTOM

THE BRAIN FROM TOP TO BOTTOM | The brain and illusions | Scoop.it

The human visual system analyzes the interactions between visible electromagnetic waves and the objects in our environment, extracts information about the world from them, and makes visual perception possible. Visual perception is considered a dynamic process that goes far beyond simply replicating the visual information provided by the retina.

Gerald Carey's insight:

Good explanations of a wide range of visual illusions.

The Secrets Behind Harry Houdini’s Ten Greatest Illusions

The Secrets Behind Harry Houdini’s Ten Greatest Illusions | The brain and illusions | Scoop.it

AltThere is an unwritten rule among magicians never to reveal how a trick is done. So when a 2004 exhibition explained Harry Houdini's illusions, magicians around the world were apoplectic. David Copperfield called it a breach of magic protocol, and performers declared that they would boycott the exhibition. Many claimed to still use Houdini's tricks themselves.

Gerald Carey's insight:

Although this article reveals a lot of the secrets of Houdini and somehow it doesn't feel right, nevertheless it is wonderful collection of his tricks and includes plenty of background text and even some videos of the events.

You can watch this video if you like but it is really a set of photos with an explanation of each type of illusion.

The author gives no references for their explanations so I would watch the video with a pinch of salt handy.

They illusions include: Green Flash (effect of the sun), Online Disinhibition Effect (changing online behaviour), Cocktail Party Effect (brain able to concentrate on loud places), The Gruen Transfer, The Moon Illusion (moon appears bigger), Tetris Effect (of mind), Illusory Superiority, The Colour of Water (colourless, but blue in oceans and rivers), Contagious Shooting, Forced Perspective (optical illusion to make an object appear farther away, closer, larger or smaller than it actually is).
