Visual perceptual Deficit- causes And Interventions.
According to researchers, like Robert Farrald and Richard Schamber, Visual Perceptual Deficit often leads to reading, writing and learning difficulties since 80% of all learning takes place through the eye and the functions of visual perception. Sudha Tumbe tells us more about the condition
Visual Perceptual Deficit, as the term implies, is a condition in which a child is unable to accurately interpret and organise visual information. According to its definition, ‘Visual Perception’ is the process of interpreting and organising visual information based on previous experiences and learning. Visual Perception is possible because of two functions:
Visual Discrimination, which involves the ability to attend to and identify an object’s distinguishing features and details such as orientation, shape, size and colour.
Visual Memory, which is the ability to store and retrieve a visual image.
Visual Perception is a very important mechanism in the process of learning to read and write. In its working mechanism, Visual Perception matches an image on a page with a previously stored image in the brain.
Also, a child must be able to discriminate between foreground, background, sizes, forms and spatial relations. However, if there is a deficit in the Visual Perception, it may lead to difficulties in learning. In fact, cognitive deficits often have their origin in Visual Perceptual Deficit, since it is the misinterpretation of what the child sees.
