Synesthesia and Perception

By
Synesthesia is an uncommon perceptual anomaly in humans where one stimulus creates more than one perceptions. There are many different types of synesthesia that range from Grapheme (color/ character), to Lexical gustatory(word/ taste). This 'disorder' of sorts is very interesting for perceptual philosophy for many reasons. It has many aspects of both cognitive science and philosophical inquiry. This cognitive phenomenon is not fully understood in terms of how it works by science. There are a few theories and the most commonly accepted one explains why it can be both inherited and it can also happen while on certain psychotropic drugs. This theory is about how the brain starts off with all the senses in one spot and they migrate to different spots. The wires sometimes get crossed and Psychotropic drugs along with genetics can mix wires in the brain up at times causing synesthesia.
This video from Michal Levy is an interesting depiction of an artistic remake of what it is like to have one type of synesthesia where music gives people a color sensation.

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
