Tetra1

imagine seeing things all the time that other people can’t? Tetrachromacy is what 12% of the female population live with every day. Women with this condition are able to see much more diverse color spectrum that is 100x greater than that of a normal person. Not every person with tetrachromacy can actually see more colors though. Some people have the condition but are unable to actually make any use of it. The reason they are able to see more colors is because of a fourth cone in their eyes. This is most likely caused by a genetic mutation in one of our light absorbing opsin molecules. Most people have three normal cones that make up what we see. These pictures above are by artist Concetta Antico, a woman with this condition. As you can see they look very colorful and almost fictional. It is hard for people who don’t have tetrachromacy to see what they artist actually envisioned while creating this, but you can kind of imagine what she sees.

Negative Afterimage

By Anonymous
Reber Shukri Professor Vaughn Negative afterimage is a stimulus which elicits a positive image. In order to experience this, one can look at a bright source of light and then look away to a dark area. The way negative afterimage works is when the eye's photo-receptors which are the rods and cones adapt to over stimulation and lose sensitivity. The photo-receptors which are constantly exposed to the same stimulus will fatigue their supply of photo pigment, resulting a decrease in signal to the brain. The way negative afterimage connects to perception is because of bottom up processing where the stimulus influences what we perceive. https://www.youtube.com/watch?v=szy8iNCljlQ <Link to the video

Illusions that Confuse Multiple Senses

By
In this video, several illusions are shown that deceive your senses. Illusions such as the Zöllner Illusion and the Poggendorff illusion confuse our bottom up processing by tricking our vision. However, our vision isn't the only sense that these illusions can confuse, blind individuals presented with raised versions of the same illusions are also confused by them. These illusions effect the visual and touch systems by confusing our bottom up processing by tricking out sight and touch. https://www.youtube.com/watch?v=Je1mkzRU5rc&t=64s

          Evolution of Camouflage & First World War Dazzle Paint Jobs           The origins of modern camouflage owes itself to 19th century naturalist painters.  The most notable of these in the development of knowledge of camouflage was Abbot H, Thayer.  While he harbored some strange views of the scientific development of animal camouflage (all animals were "camouflaged")  He noticed the effect of disruptive patterning and countershading.  He noted that animal markings tended to obstruct their shape in nature.  Their coloring added with this made them often completely invisible. By going from darker shades on top to lighter on the bottom animals canceled out the way we see objects by light illuminated them top down.  Black also aided in disruptive schemes. An example of Countershading. Abbot's demonstration of disruptive patterns. In this image we can see how disruptive patterns observe...
