The Processes of Visual Perception and Visual Sensation
Visual perception and visual sensation are both interactive processes, although there is a significant difference between the two processes. Sensation is defined as the stimulation of sense organs Visual sensation is a physiological process which means that it is the same for everyone. We absorb energy such as electro magnetic energy (light) or sound waves by sensory organs such as eyes. This energy is then transduced into electro chemical energy by the cones and rods (receptor cells) in the retina. There are four main stages of sensation. Sensation involves detection of stimuli incoming from the surrounding world, registering of the stimulus by the receptor cells, transduction or changing of the stimulus energy to an electric nerve impulse, and then finally the transmission of that electrical impulse into the brain. Our brain then perceives what the information is. Hence perception is defined as the selection, organisation and interpretation of that sensory input.
Perception is defined as the process of organizing, interpreting, and selectively extracting sensory information . Visual perception is left to the individual person to make up their own mind. Perceptual organisation occurs when one groups the basic elements of the sensory world into the coherant objects that one perceives. Perception is therefore a process through which the brain makes sense of incoming stimuli.
The process of perception is an interactive yet separate process from sensation, however, it is sometimes difficult to separate the two processes. The main difference is that sensation is where our sense organs first encounter raw stimuli. Perception is the process by which the stimuli are interpreted, analysed, and integrated with other sensory information.
An experience from everyday life that helps to work out perception and sensation is a football game. A ball could be kicked towards the goals. Two people will see the same ball going in the same direction at the same time yet one could say that the ball was a goal and the other could say that the ball went in through the goals for a point.
There are many different Visual Perception principles in perception. The main principles are Gestalt. Gestalt is a German word meaning 'form' or 'shape'. Gestalt psychologists formulated a series of principles that describe how t...

...the other end there are only two. Such a figure is an impossible figure. It is possible, because, the depth cues and shape cues of one part of the figure do not have to be consistent with the depth and shape cues of another part of the same figure.
There are six diagonal lines. At one end there are circles on them giving the impression of three circular prongs. At the other end the same size lines have cross connecting lines consistent with two square prongs. These perceptions can violate our expectations for what is possible often to a delightful effect.
Our psychology class did an Empirical Research Assessment on perceptual set. The ERA consisted of showing people pictures of faces and then showing a picture of a face/rat. The same was then done to a different group of people using pictures of different animals and then the face/rat picture. The picture of the man/rat could neither be decided if it was a rat or a man. This experiment showed the deception of showing a person previous pictures influenced the decision on which the subject would make.
Visual perception plays a big part on how we perceive life. If we didn't have perception I don't know where we would be now.

...o identify any geometric shapes someone would recognize. We see trees, people, and clouds. As a matter of fact, not even the staff the man in the focal point is holding is geometrical in shape, but crooked, as if it had been used for years. It is amazing how both geometric and organic shapes can create something that looks almost as authentic as a picture.
What is sense perception? Everything we perceive in our senses can be misleading and an illusion. In the article “Perception and Reality” by Keith Wilson (see Article 1), the author goes over some of the aspects of how our perception deceives us to believe in things that aren’t there to begin with. For example are colors real? Well that is relevantly dependent on what is considered real, because real again is a perception of a single individual collecting information and making “sense” out of it. A color being real or not is dependent on how we see it through our eyes, we can 't say that my blue is the same as your blue. We can 't know for sure if what we are seeing for ourselves, is the same as what the person that views that same thing sees
ABSTRACT: The aim of this paper is to defend a broad concept of visual perception, according to which it is a sufficient condition for visual perception that subjects receive visual information in a way which enables them to give reliably correct answers about the objects presented to them. According to this view, blindsight, non-epistemic seeing, and conscious visual experience count as proper types of visual perception. This leads to two consequences concerning the role of the phenomenal qualities of visual experiences. First, phenomenal qualities are not necessary in order to see something, because in the case of blindsight, subjects can see objects without experiences phenomenal qualities. Second, they cannot be intentional properties, since they are not essential properties of visual experiences, and because the content of visual experiences cannot be constituted by contingent properties.
For example, he argues, that the experience of temperature can be understood with the analogy of the experience of pain, and just as the pain is not 'in the needle', so the warmth I feel is not in the fire. (2) He then argues in a similar vein that visual experience is reducible to collections of colour sensations because light passes into the eye ball and strikes the retina, in much the same way that a sharp object striking the skin produces a sensation of pain, such as a sensation of blue or red. (3) The sensation being the effect of the physical and chemical properties of the world on the sense organs and is as distinct from the world as photographic images are from the objects which cause them.
Our five senses –sight, hearing, smell, taste and touch help the ways in which we perceive the world around us. And while they seem to work independently at time they can effect each other and the way we comprehend something. Seeing something pretty, touching something soft, eating something cold and smelling something rotten are the sense we use to connect with the world around us and will all effect how we move forward in that situation. When you look at the top picture say the color of the word not the word itself. It is harder than it seems and takes a little practice to do it efficiently. It is because we see the spelling we were taught not the color it was written in. It is hard to process it the other way, but not impossible. Take the bottom picture for another example is this a
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.

Visual Discrimination is “using the sense of sight to notice and compare the features of different items to distinguish one item from another” (NCLD Editorial Team, 2014) http://www.ncld.o...
Each one of us lives in our own unique world of perception. As individuals, we may experience life in an entirely different way through our senses and life experiences. Therefore, perception can be tricky since it is very personal to each one of us. According to the Merriam-Webster online dictionary, perception has three meanings; (1) “the way you think about or understand someone or something,” (2) “the ability to understand or notice something easily,” and, (3) “the way that you notice or understand something using one of your senses” (2014, para. 1). C.S. Lewis said, “What you see and what you hear depends a great deal on where you are standing. It also depends on what sort of person you are” (n.d., para. 11). In other words,
As humans, we interact with the world around us in five main discernible ways: seeing, hearing, tasting, touching, and smelling. Appropriately, they are known together as the five senses, five clearly distinguishable ways we could familiarize ourselves with an environment or recognize a new situation which we have not encountered before. As discussed in class, they help the brain perceive the world around us in a way where we can understand and react to everything which is happening around us. It is not just humans who have these abilities either, as almost all animals rely on at least one sharpened sense to help them avoid danger on a day to day basis and survive in whatever environment they live in. While none of our sensory abilities may be the strongest ones individually compared to certain ones in certain other animals, what makes humans unique as a species is that we possess an ability to input the information all of
With each of our senses (sight, smell, touch, taste, and hear), information is transmitted to the brain. Psychologists find it problematic to explain the processes in which the physical energy that is received by the sense organs can form the foundation of perceptual experience. Perception is not a direct mirroring of stimulus, but a compound messy pattern dependent on the simultaneous activity of neurons. Sensory inputs are somehow converted into perceptions of laptops, music, flowers, food, and cars; into sights, sounds, smells, taste ...
Perception, at most times, is a credible way to assess the world around us. Without perception, we would not know what to do with all the incoming information from our environment. Perception is constructed of our senses and the unconscious interpretations of those sensations. Our senses bring in information from our environment, and our brain interprets what those sensations mean. The five most commonly accepted senses -- taste, smell, hearing, sight, and touch -- all help create the world around us as we know it.
Perception is a mysterious thing; it faces a lot of misconception, for it can merely be described as a lens, as it decides how someone views the events happening around them. Perception is the definition of how someone decides to use their senses to observe and make conceptions about events or conditions they see or that are around them. Perception also represents how people choose to observe regardless if it’s in a negative or positive way. In other words, perception can be described as people's cognitive function of how they interpret abstract situations or conjunctures around them. All in all, perception can do three things for someone: perception can change the way someone thinks in terms of their emotions and motivations, perception acts
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system.
