Optical Illusions

According to the article written by Carbon C. C. (2014), perceiving illusions may be fun, but it is even more stimulating to know how they work. They can also tell us where the location of the visual constraints is a. It is also possible to analyze the cognitive sub-process underlying our perception. The scientific context of our illusions points to the specific power of human perception. The context of the misconceptions is not to reveal failures of our perceptions or the disfunction of our apparatus. Human perceptions’ primary objective is to amplify and strengthen sensory inputs to perceive, orientate, and act quickly, efficiently, and precisely.

‘We can regularly find out that our perception is indeed mostly very reliable and also objective by analyzing the quality of our perceptual experiences by standard methodological criteria. (Gregory and Gombrich, 1973).”

Regina Wang and associates published an article named “Composition Methodology of Optical Illusion.” Researchers wanted to illustrate how the optical illusion is required to turn a concept design into a picture/composition. Researchers stated, “Optical illusions have interesting visual effects, which attract the viewer and hold their attention during the transfer of information. Thus, vastly used in advertising design, artistic drawing, fashion, and environmental spaces (Wang et al., 2012). Meaning optical illusions can happen when something grabs someone’s visual attention. When an object catches our eye, it grabs our attention, like watching an advertisement on tv or a deer in the field.

Bottom-Up and Top-Down

Perception refers to how sensory information is, organized, interpreted, and consciously experienced. Perception involves both bottom-up and top-down processing. One way to think of the concept is sensation is physical (bottom-up processing), and (top-down processing) is psychological. Bottom-up processing implies that perception is built from sensory input. We interpret these sensations by our available knowledge, experiences, and thoughts. Top-down processing refers to how we interpret feelings because of our general knowledge, experience, and ideas. (Goldstein,2015)

“Top-Down processing is the schemata or knowledge of learners to understand the information received, while Bottom-Up processing is the process of understanding the information through the analysis of sound, sense of the word, and grammar” (Ardini, 2020). Researchers conducted a study to look into students’ problems in learning to listen since the observation results showed the grades were low. The result showed that 90% of the students found that, Bottom-Up processing is more problematic than Top-Down processing (10%). Research has also shown that when the stimulus is, introduced short or fast, and the meaning is unclear, offering a vague incentive is a top-down strategy. However, bottom-up processing is a method where various specific components make up the whole (McMains & Kastner, 2011). For example, top-down processing happens when someone tries to decipher difficult handwriting. It is easier to read whole sentences than to read separated phrases because the meaning of the words around them provides a framework for understanding. While bottom-up processing happens when you see an image of a single letter on your screen, your eyes convey the information to your brain, and your brain puts all of this information together (McMains & Kastner, 2011).
