Why Can We See Pictures As Moving Illusions?


 In this video, Inside Science explains how we see certain illusions as shifting pictures. Our brain takes a frozen image and begins to fixate on a certain area of the photo. We do this multiple times but when we fixate on one spot for a few milliseconds, we move onto the next area of the photo while our eyes are continuing to remember the last part of the photo that you saw, which is what gives the illusion of movement. Neuroscientists are still not exactly sure what causes our brains to function this way.

Self Perception Theory

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

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

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
