Finding the Blind Spot in Your Field of Vision

By
Each of your eyes has a blind spot on the retina. This blind spot is where the optic nerve connects to the retina. Watch this video to find your blind spot.


The reason you cover one of your eyes is to prevent that eye from compensating for the blind spot in the other eye. Without that compensation, your mind then fills in the blind spot with surrounding visual stimulus. In other words, if you used a white 3 x 5 card then you noticed that the dot disappeared into the white of the 3 x 5 card.

    In fact, if you are paritally blind as I am, your mind can create a visual where none exists.

Self Perception Theory

By Anonymous
https://study.com/academy/lesson/self-perception-theory-definition-and-examples.html This link relates to how perception can be pointed inward upon ourselves. Addressing this is the Self Perception theory, which plays the idea that people create their attitudes by observing their own behavior and then making an assumption on what attitudes must have caused it. I found this video to relate well to perception, but also to exemplify just how powerful our brains truly can be. An interesting concept, I thought. I hope you do too!

Human Perception and it's Fascinating Facts

By
The human mind is capable of so many. different things that are turly incredible but most of the these incredbile things we take for granted. This article shows us the simple visual aspects and how our braing forms them within our mind. Throughout the article there are examples for different kinds of laws. These laws include Law of Proximity or Nearness, Law of Similarity, Law of Good Figure or Symmetry, Law of Closure, and Law of Continuity. All of these laws sound complicated and you amy assume that they are complex, however they aren't anywhere near that level. They are rather explnations for the reasoning behind why we perceive what we perceive. https://www.online-therapy.com/blog/human-perception-fascinating-facts/

The Rotating Mask Illusion- Schizophrenia

By Anonymous
A schizophrenic process is more of a bottom up process  than  a top down which is what we do. We are unable to see a hollow face at first because we have never seen that before in our prior experience. This illusion occurs because the brain interprets information based on context and previous experience, or top down processing. In schizophrenic people there is a dysconnectivity between the parietal cortex, where top down occurs, and the lateral occipital cortex, where bottom up occurs, which is why they see the hollow face right away. In healthy people the connectivity in these areas are increased which is why they see a regular rotating face
