The Ponzo Illusion

Hello and welcome back to the...

AWESOME ILLUSIONS BLOG
where I talk about illusions

Today I talk about the..
Ponzo Illusion!

Look at this picture...

You will probably notice 2 lines which  the near line is smaller than the far line.

What if I told you these 2 lines were the same size? DUNN DUNN DUNNNNNN

This is called the Ponzo Illusion

How It Works
The Ponzo Illusion was first demonstrated by Mario Ponzo in 1913.

We view this scene using leaner perspective or one point perceptive as shown in class.

Our brain thinks that since the second line seems to be farther away than the first, it would need to be longer in order to match the size of the the first line. As a result our brain decides to "edit" the picture and make the line seem longer.

The Spinning Dancer Illusion

Hello and welcome back to the......
AWESOME ILLUSIONS BLOG

Today i'm going to talk about optical illusions (Illusions that mess with your eyes and your brain)!!

The Spinning Dancer Illusion
WATCH THIS

If you click on the text above it will take you to a picture of a lady spinning. The question is..... Which way is she spinning?!?!?!

Some people see it spinning left to right some people see it spinning right to left. This depends on your perception and which side of your brain is dominant.

But this is still an optical illusion.

In the picture there is no 3rd dimension so your brain attempts to fill in the gaps or edit the picture. as I said before..
As a result their is 2 different perceptions. for your brain to choose.

If you were to stare at the picture long enough, you might blink and see the dancer spin in the opposite direction

Here, let me help you
In the link above the creator has drawn different colours so you see different perceptions!

Post which way you see the spinner spinning in the comments!

Overall Illusions.

Hello and welcome the the..

AWESOME ILLUSIONS BLOG

I will be learning about the 3 types of illusions in the span of a month.
Today I learned about the overall types of illusions and how scientist group all these illusions.

What are illusions

Illusions are tricks and games that tend to play with your ears, eyes, skin, and the brain.
For example: optical illusions mess with your eye and your brain.

Types of Illusions

Scientist group illusions into three types...

Optical illusions

These are illusions that trick the brain and the eyes. Brains tend to "edit" the things you see based on perception and past memory. So if there is a gap such as a shadow, your brain attempts to fill in the gap

Auditory Illusions

These illusions trick the ears and brain similar to the way they do with the eyes.

Tactile Illusion

These illusions are illusions that trick the sense of touch
