How Your Expectations Mess With The View of The Present

In this video the waiters and waitresses give the customers a water menu with fancy different names. They then taste the differently packaged water. Since they were convinced that they were actually different types of water, they were comparing them and actually tasted a difference. The reasoning behind this is, since they were told that they were different, they believed what they were told. They perceived what they expected it to be. This is is an example of how your expectations mess with your view of the present. Therefore, they tasted the water to be different but in reality it was tap water the whole time in different bottles.

Negative Afterimage

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

Typoglycemia and Predictive Coding

https://www.mrc-cbu.cam.ac.uk/people/matt.davis/cmabridge/ This article was the basis of my presentation in class, but due to the 5 minute time limit I was only able to mention a fraction of the information. The page focuses on the original "copypasta" text: Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae.

He breaks this down sentence by sentence, first doing a quick search to see if there's actually research being done at Cambridge University on the topic (there's not). He lists a multitude of studies that are relevant to the orders of the letters, the impact these jumbles have on reading speed, and more. The article makes a strong case that we read wo...

Illusions that Confuse Multiple Senses

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
