Cognitive Processes Involved In Perception Essay

971 Words4 Pages

To which extent do the cognitive processes involved in sensation are the same as in perception?

Cognitive researchers have been studying the mental structures involved in imagining objects, people and what happens when we see them, for quite some time now.
On one hand, some people believe that there is no connection between the processes of imagining and seeing, which does not make much sense for the brain to have separate ways of processing this information. On the other hand, others believe the brain processes imagining and seeing in the same way, which, if this is the case then how could we separate reality from imagination? We could not. And we would probably go into hallucinatory delirium. (Tomlin, A. (2016) Introduction to cognitive psychology [PowerPoint Slides])
That is why, in my opinion the most correct way to analyse the …show more content…

When the rods and cones are stimulated, they cause chemical variations that spur neural signals, which triggers the cells behind them, called bipolar cells, whose job is to turn on the ganglion cells. The axon tails of the ganglions interweave together to form the optic nerve, that transmits the neural impulses from the eyeball to the visual area of the thalamus and afterwards to the brain visual cortex. The right cortex processes input from the left eye and vice-versa.
This cortex has dedicated cells called feature detectors that answer to specific figures, angles and movements. The incapacity to process and examine numerous aspects of a condition at once is called parallel processing, subsequently the brain simultaneously tries to add up of colour, motion, form and depth.

This is examined through how our senses use feedback from the body to the brain reinforcing our perception. “The brain relies on the fact that there are certain qualities to the world that are constant and unchanging, filtering the glut information and eliminating detail in favour of basing perception on memories of what it already knows to be

This proves perception is abstract, or different for everyone. To give real world evidence of differing perceptions, the field of psychology also notices the importance of perception. Many psychologists separate interpretation into two categories: sensation and perception. Sensation representing physical sensations of stimulus, and perception being the personal interpretation.

Perception is the organisation, identification and interpretation of sensory information in order to represent and understand the environment. Like perception, logic plays a role in critical thinking. Critical thinking is the process in which one mentally explores deeper than the superficial matters at hand into the deeper layers in order to find out what the real issues are. However, when it comes to weighing their beneficial impact on the critical thinking process, logic and perception are by no means equal. While logic is firmly rooted in reason, perceptions are just as firmly rooted in one’s senses and can easily be corrupted.

Sensation and perception are two very different things, that when used together help our brains string together a reality. Sensation is the use of our physical stimuli such as our nose, eyes, ears, and touch. This is where our perception comes in to use these tools to select, organize, and interrupt this information. In the Ted Talk video he states “your perception is not always reality”, which can be a hard concept to grasp and raises a lot of questions. I know people come from all walks of life and backgrounds and have seen different things, and know different things to be true, but how differently do others see the world from me?

Running Head: SYNESTHESIA Synesthesia Emma Grace Hardin West Texas A&M University Imagine seeing color when listening to music, tasting shapes, or even tasting words when hearing someone speak. These are just a few examples of a condition called synesthesia. Synesthesia is the input of one sense that results in the experience of another sense. For example, when a synesthete, someone with synesthesia, looks at numbers, he or she may see different colors for each number.

In film making, Visual Effects means creating a processed image with a brand new environment outside the context of a live shot, because VFX allow to create a unique world or places that may be impossible to capture, expensive to reach, impractical for acting or just dangerous. Furthermore, Visual Effects help to give a realistic look to the live action footage, as well as a brand new world totally integrated in it. According to the history, we can say that Visual Effects have been used in films almost from the beginning of film creation: it’s easy to remember George Méliès, a French magician and film director who used Visual Effects extensively around the 1900s and 1910s.

The concepts and ideas of how we see, perceive and form an understanding of the world have been frequently explored, even before the inventions of the camera and photography. It’s therefore crucial to the question posed that this fundamental knowledge is attained to better support the more specialised presuppositions that revolve around the camera. Focusing on the likes of Descartes and Kant, and the philosophical theories that they explore, will help in supporting my explanation of the question that focuses around sight and perception. Rene Descartes’ ‘A Discourse on Method’ and ‘First Meditations of Philosophy’ separate the mind and soul from the body. ‘A Discourse on Method’ considers approaches to epistemology - which is the theory of

Today in class we participated in an activity called, sitting volleyball, a form of volleyball that is played in the Paralympic Games. (Olympic style games for athletes with disabilities.) This activity helped me understand the fundamental skills that are needed for disabled players to participate in athletic activities. Some of the adaptations made for this game were lowering the net, decreasing the team sizes, changing the court sizes and changing the way players moved on the court.

99). There are three structures involved in the information processing model; sensory register, short-term store and long-term store (Tangen & Borders 2017, p. 99). The sensory model is a way of attaining information through any of the five senses; smell, sound, taste, sight and touch (Tangen & Borders 2017, p. 101). Most information attained through the senses only lasts for up to three seconds (Tangen & Borders 2017, p. 101). However, if attention is paid to the information, it can be processed to the short-term store/ short term memory (Tangen & Borders 2017, p. 101).

Communication and Perception In psychology, perception is understood as the process by which a person acquires information from his surroundings or environment and his ability to understand it (Stanford University, 2006). Perception makes use of the senses to experience things but it is the interpretation that really defines a person’s perception. In other words, perception is how people make sense of the things they see, feel and heard. For instance, the common adage that says, ‘beauty is in the eye of the beholder,’ holds true because people have different perceptions when it comes to what is beautiful and what is not.
