Perception in the periphery//experiencing candy with all the senses

This is a short video that can help you to explore how much you actually see with your peripheral vision. As you may recall from my in-class demonstration, you can see movement first with your peripheral vision and as objects move to your central line of vision, you can slowly see shape, color and then finally read words. This is because the structure of the eyes (with ratio of cones and rods) differs within the fovea and sides of eye. However, this relates to perception because we fill in missing things with our mind and we perceive color and shapes out of the corner of our eyes. We also use active perception by moving our eyes and exploring the area around us with our sight.

I also brought candy to demonstrate that much of the information that we think we get from taste actually comes from smell. I think this is evidence that much of what we perceive is coming from different senses and being combined in a way to create what we experience.

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

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

Visual Perception- Spinning Dancer

This relates to what we’ve discussed in class because of the visual perception aspect and that the ability to perceive motion is very important to daily life. Shadows or visual cues can change your visual perception of an object and the motion. This relates to the bottom-up processing because its about processing information. Bottom-up processing deals with sensory information. We perceive the dancer turning one way because the cues we receive from our experiences affect what we perceive. What you perceive is based on the sensory information that is coming in.
