Perhaps the best illustration of vision therapy in the treatment of visual processing disorders comes in patients with brain injuries, as the presence of an injured brain makes treatment more challenging. How are visual information processing deficits treated? Visual attention is also implicated in the development of dyslexia. Vision therapy for visual attention deficits have been shown to improve reading comprehension in children by 220% and increase overall attention in the classroom. Visual attention: The ability to attend to stimuli and shift attention between stimuli. Saccadic eye movements are normally executed in an organized, systematic, and efficient pattern.

The eyes obtain and process information by executing a series of broad sweeping cycles with reexamination of the most important details several times to ensure identification. The route taken is known as the scan path. Scanning: The ability to record all details of a scene systematically in an organized and thorough manner. It is important for the individual to be able to recognize objects even when viewed from different or obscure angles (perceptual constancy). Pattern recognition: The ability to identify the salient features of an object including configural and holistic aspects such a shape, contour, and general features, such as color, details, shading, and texture. The individual must also be able to match what they see with what is stored in memory.
Visual memory: The ability to visually process stimuli, store them in memory and retrieve them upon command.
It also includes the ability to use contextual cues to help in the development of meaning from the image. It includes the ability to analyze similarities and differences, to understand the relationship of stimulus elements to one another, and to reason and deduce about the nature of visual stimuli. Visual cognition: The ability to mentally manipulate visual information and integrate it with other sensory information to solve problems, formulate plans and make decisions. These functions can be described as follows: In her model, each skill level is dependent upon the skill level below it, and relies on the following functions: including visual cognition, visual memory, pattern recognition, scanning and visual attention. An example of the latter is found in the work of Warren who appears to have provided the best approach towards understanding visual processing. These include the Deficit Skill Approach which categorizes visual processing into specific deficits, and the Information Processing Models, which describe the reception organization and assimilation of visual information on a continuum from simple to complex. "There are a large number of identifiable visual processing skills operating within the visual system, and there have been several attempts to describe them in some kid of rational framework. The authors provide a good summary explanation of visual processing and its component parts (visual cognition, visual memory, pattern recognition, scanning, visual attention). Visual information processing and visual skillsĪn excellent explanation comes from a 1996 study from the field of rehabilitation medicine published in the journal NeuroRehabilitation by Raymond et al.
