Are you curious about how we take in the visuals in an environment filled with strong sensory stimuli and how we interpret what we see? The phenomenon is called visual information processing or visual perception. Visual information processing is the visual reasoning skill that enables us to process and interpret meaning from visual information that we gain through our eyesight.
A review study concluded that using graphic organizers improves student performance in the following areas: The basis of this work takes place in the visual cortex of the brain.
The visual cortex is located in the occipital lobe of the brain and harbors many other structures that aid in visual recognition, categorization, and learning. One of the first things the brain must do when acquiring new visual information is recognize the incoming material.
Brain areas involved in recognition are the inferior temporal cortexthe superior parietal cortexand the cerebellum. During tasks of recognition, there is increased activation in the left inferior temporal cortex and decreased activation in the right superior parietal cortex.
The three main areas that are used when categorizing new visual information are the orbitofrontal cortex and two dorsolateral prefrontal regions which begin the process of sorting new information into groups and further assimilating that information into things that you might already know.
Multiple brain areas are involved in this process such as the frontal lobethe right extrastriate cortexthe neocortexand again, the neostriatum. One area in particular, the limbic -diencephalic region, is essential for transforming perceptions into memories. One can remember visual images much better when they can apply it to an already known schema.
Schemas actually provide enhancement of visual memory and learning. Gray matter is the darker tissue of the brain and spinal cord, consisting mainly of nerve cell bodies and branching dendrites.
The four pathways[ edit ] Within the primary visual cortex, there are four pathways: Each pathway is crucial to the development of visual attention in the first few months of life.
The SC pathway is responsible for the generation of eye movements toward simple stimuli. It receives information from the retina and the visual cortex and can direct behavior toward an object.
The MT pathway is involved in the smooth tracking of objects and travels between the SC pathway and the primary visual cortex. In conjunction with the SC pathway and the MT pathway, the FEF pathway allows the infant to control eye movements as well as visual attention. It also plays a part in sensory processing in the infant.
Lastly, the inhibitory pathway regulates the activity in the superior colliculus and, later, is responsible for obligatory attention in the infant. The maturation and functionality of these pathways depends on how well the infant can make distinctions as well as focus on stimuli.
Expectations in this study refer to the cognitive and perceptual ways in which an infant can forecast a future event. For example, anticipatory looks exhibit the infant is able to predict the next part of a pattern which can then be applied to the real world scenario of breast-feeding.
Expectations, anticipatory looks, and disengagement all show that infants can learn visually, even if it is only short term. At this age, toddlers are using their newly developed sensory-motor skills quite often and fusing them with their improved vision to understand the world around them.
The act of bringing objects close to their face affects their immediate view by placing their mental and visual attention on that object and just blocking the view of other objects that are around them and out of view.
There is an emphasis placed on objects and things that are directly in front of them and thus proximal vision is the primary perspective of visual learning. This is different from how adults utilize visual learning. This difference in toddler vision and adult vision is attributable to their body sizes, and body movements such that their visual experiences are created by their body movement.
An adults view is broad, due to their larger body size, with most objects in view because of the distance between them and objects. Adults tend to scan a room, and see everything rather than focusing on one object only.Help your child thrive.

Each of these elements help you to design your photograph such a way that it emphasizes one or the other important aspect in composition.
They bring an order in to a photograph. In this article we will briefly discuss about each of these elements of design.
Line. Line is the most important element of all and also the most strongest in its meaning. Your eyes follow the line whether it is visible or invisible. If you are required to use a visual aid in your presentation, you should be glad!
Visual aids can improve your presentation in many ways. They can clarify information for the audience, and help you, as the presenter, focus on the topic at hand.
Film, whether still shots or moving, is a visual medium, and stories are told through a combination of visual and other elements, which illustrate the human condition.
What still photographers are often doing is trying to catch a moment of human drama to tell a "story" through a captured moment in time.
9 Conducting Visual Arguments In today’s visually oriented culture, arguments increasingly use photographs, Understanding Design Elements in Visual Argument To understand how visual images can produce an argument, you need to under- Here are some ideas to help you think about the layout of a visual argument.
