Quirky New Chalk Characters on the Streets of Ann Arbor by David Zinn

Quirky New Chalk Characters on the Streets of Ann Arbor by David Zinn | The brain and illusions | Scoop.it
Michigan illustrator David Zinn (previously) has brightened the streets of Ann Arbor with his off-the-wall (or technically on-the-wall) chalk drawings since 1987. The artist works with chalk or charcoal to create site-specific artworks that usually incorporate surrounding features like cracks, s

The freakish optical illusion that shows how your brain sees faces

The freakish optical illusion that shows how your brain sees faces | The brain and illusions | Scoop.it
A 35-year-old optical illusion is still astounding people. And it all revolves around a rotated picture of Margaret Thatcher.

But, as with many optical illusions, the strange effect shows a lot about the way that the brain processes images.
Gerald Carey's insight:

I didn't realise that this was first called the Margaret Thatcher illusion. How entirely appropriate!

Gerald Carey's insight:

Kokichi Sugihara has become a master of creating impossible 2D drawings into 3D images like Eicher's staircase above.

I like this quote from the article:


"The human brain routinely throws away many possible interpretations of the visual data it receives from the eyes. Given the brain’s limited resources and its need to interpret visual data quickly, it can’t afford to entertain every bizarre interpretation—it simply goes for the explanation that seems most likely, based on its past experiences and built-in visual processing machinery."


This could be one of the reasons why will settle on illusions (e.g. Jesus on toast) so quickly.  Of course, magicians use this phenomenon all the time.

How to evaluate an argument like a trained scientist

How to evaluate an argument like a trained scientist | The brain and illusions | Scoop.it

From the pontifications of the politician on the nightly news, to the latest tabloid health scare, we're constantly bombarded by other people's arguments – their attempts to make a particular claim based on some kind of evidence. How best to evaluate all these assertions and counter-assertions? Some insights come from a 

Gerald Carey's insight:

Putting this article within this group of scoops is a bit dodgy but I like the article and can justify it by describing how to avoid illusions in our thinking.  

The article explores the mechanisms used by experience scientists and students in deciding if text examples were plausible.

This Rabbit-Duck Optical Illusion Can Reveal How Quick Your Brain Is | The brain and illusions | Scoop.it
What do you see in this image: a duck or a rabbit? This optical illusion sketch was created about 100 years ago, but recently sparked huge reaction on internet after being shared on social media sites. The Duck-Rabbit image is believed to have first published in 1892 in a German magazine - Fliegende Blätter - with title "Which animals are most like each other?"

The conclusions on this page are entirely spurious but I did like the way they classified illusions into four types.

Illusions for survival and reproduction | OUPblog

Illusions for survival and reproduction | OUPblog | The brain and illusions | Scoop.it
Much of what we think we see is not real – it’s an illusion. A favourite pastime for many visual psychologists and artists is to baffle and confuse our perception by making things appear that are not really there, or manipulating the way that we might see patterns or colours. The origin of many illusions lies in the fact that the brain often receives incomplete or conflicting information.
Gerald Carey's insight:

Really good example of an animal using force perspective to create a 'bower' which makes the smaller objects near the front look as big as the larger objects in the rear. Who would have thunk it!
