How the brain leads us to believe we have sharp vision

How the brain leads us to believe we have sharp vision | The brain and illusions | Scoop.it
We assume that we can see the world around us in sharp detail. In fact, our eyes can only process a fraction of our surroundings precisely. In a series of experiments, psychologists have been investigating how the brain fools us into believing that we see in sharp detail.
Gerald Carey's insight:

A review of an experiment trying to work out why the world appears so detailed even though we can only really see the detail of a small part of the world that is processed by our eyes.

Don't underestimate your mind's eye: Objects don't need to be seen to impact decision-making | The brain and illusions | Scoop.it
Objects in our visual environment needn't be seen in order to impact decision making, according to new research. Take a look around, and what do you see? Much more than you think you do, thanks to your finely tuned mind's eye, which processes images without your even knowing.
Gerald Carey's insight:

Not sure about this study but the picture above was interesting. When I first looked at, I couldn't see any pattern. When I read that it was two halves of a maple leaf, I instantly saw it!

Dark side of cognitive illusions explored in bias research

Dark side of cognitive illusions explored in bias research | The brain and illusions | Scoop.it

A cognitive bias, the “illusion of causality,” has been explored by a joint team of scientists who found that the bias isn’t limited to false beliefs about whatever was originally learned; later on, the bias can prevent new information from being learned — even when the original information is false and the newer information is true.

The Weird Connections Between Hearing and Taste

Headphones could make those Pringles seem crunchier.
Gerald Carey's insight:

Recount of a couple of experiments (including the well-known "Pringle" test) showing how sound influences our perception of flavour. I think the author is too quick to jump to conclusions about this BUT it is worth reading about how restaurants and supermarket chain use sound or music in their stores.

The above statement from the website is a paragraph that you should read out to your friends and ask them if it is a good description of their personality.
