The Processes of Visual Perception and Visual Sensation...

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†¦show more content†¦Figure-ground involves the target stimulus being called the figure, while everything that surrounds this figure is called the ground, or background. The differentiation between these is called figure-ground perception. In perception we give most of our attention on the figure. Studies of the way people view pictures have shown that most attention is given to the figure and little is reserved for the ground. This difference was recorded when the recording of eye movement patterns of individuals while they looked at pictures took place. Some important factors that influence the way people determine the figure from the ground included size: the smaller the area were more likely to be seen as a figure than larger areas. Familiarity is also important, meaning that familiar shapes and forms are more often perceived as figures. Also objects that are symmetrical are more often seen as figures. Advertisers use this deliberately to make customers think of their product and remember it. The figure-ground tendency is exploited in reversible figure-ground figures. It is a coarse rendition of the vase/two faces figure. The drawing can either be seen as a central white vase, or two black faces looking at each other. Generally when you see one of the perceptions, the oth er regions forms a background and is not seen. So to see both perceptions requires switching to one from the other. Another principle involved in visual perception is called closure.Show MoreRelatedVisual Perception1268 Words   |  6 PagesVisual perception and visual sensation are both interactive processes, although there is a significant difference between the two processes.

This ability to perceive and interpret stimulus allows the human being to make meaningful sense of the world and environment around them. However, even as the human being is able to perceive and interpret stimuli informationRead MoreDifferent Visual Illustrations in Perception Essay1471 Words   |  6 PagesDifferent Visual Illustrations in Perception How can visual illusions illustrate top down processes in perception?

Topic 2: Cognitive Processes This study may have shown that a student is able to affectively use textisms without impairing their literacy skills but there is still the question of how this is possible. In order to understand how the use of textisms impacts on literacy skills, one must have a firm grasp on the mechanics of cognitive processes. According to Gerrig et al.

The first level of integration occurs when the five major sensory systems are stimulated adequately and their impulses travel from the receptors to the brain. Integration primarily occurs within the vestibular, proprioceptive and tactile systems at this level because the organisation of a child’s CNS depends upon these more basic sensations, rather than visual and auditory sensations (Ayres, 2005:54). Kianah’s vestibularRead MorePsychology : Sensation And Perception Essay841 Words   |  4 Pages1. Define sensation and perception. How do sensation and perception differ from cognition? How might sensation and perception be related to cognition? a. Although sensation and perception are closely related, it is very important to understand the difference between the two. Sensation is the process of sensing our environment using our different sensory systems. There are four different systems: visual, auditory, cutaneous, and chemical. The information we acquire through sensation is then sent toRead More Visual Form Agnosia Essay1569 Words   |  7 PagesVisual form agnosia is defined as the inability to recognize objects (Goldstein, 2010). To understand the basic concept of visual form agnosia, it is important to first understand that perception and recognition are separate processes. Perception is defined as the ability to become aware of something through our senses, and recognition is the ability to put an object in a group that gives the item meaning. When a person suffers from visual form agnosia, they are generally able to identify the itemRead MorePerception Plays A Huge Role In Someone’S Life. â€Å"When A1297 Words   |  6 PagesPerception plays a huge role in someone’s life. â€Å"When a distinction is made between sensation and perception, sensation is frequently identified as involving simple â€Å"elementary† processes that occur right at the beginning of a sensory system, as when light stimulates receptors in the eye.
