V.P.D stands for Visual Processing Disorder and it is more common than we realize.
What are visual processing issues?
When people think of eyesight, they usually think about acuity, as in 20/20 vision. But vision is much more than that. The brain, not the eyes, processes the visual world, including things like symbols, pictures and distances. Weaknesses in these brain functions are called visual processing disorder or visual processing issues.
Visual processing issues don’t just affect how a child learns. They also impact his ability to do ordinary things like sorting socks or playing a simple game of kickball. Visual processing issues can cause problems with socializing and self-esteem, too. Some kids may become frustrated and withdrawn.
Eight Types of Visual Processing Issues
Visual processing issues are complex. That’s because there are eight different types, and people can have more than one. These issues often go undetected because they don’t show up on vision tests. Here are the different types of visual processing issues scientists have identified:
- Visual discrimination issues: Kids with this type have difficulty seeing the difference between two similar letters, shapes or objects. So they may mix up letters, confusing d and b, or p and q.
- Visual figure-ground discrimination issues: Kids with this type may not be able to pull out a shape or character from its background. They may have trouble finding a specific piece of information on a page.
- Visual sequencing issues: Kids with these issues have difficulty telling the order of symbols, words or images. They may struggle to write answers on a separate sheet or skip lines when reading. They also may reverse or misread letters, numbers and words.
- Visual-motor processing issues: Kids with these issues have difficulty using feedback from the eyes to coordinate the movement of other parts of the body. Writing within the lines or margins can be tough. Kids also may bump into things and have trouble copying from a book.
- Long- or short-term visual memory issues: Kids with either type have difficulty recalling what they’ve seen. Because of that they may struggle with reading and spelling. They may also have trouble remembering what they’ve read and using a calculator or keyboard.
- Visual-spatial issues: Kids with these issues have difficulty telling where objects are in space. That includes how far things are from them and from each other. It also includes objects and characters described on paper or in a spoken narrative. Kids may also have a tough time reading maps and judging time.
- Visual closure issues: Kids with these issues have difficulty identifying an object when only parts are visible. They may not recognize a truck if it’s missing wheels. Or a person in a drawing that is missing a facial feature. Kids may also have great difficulty with spelling because they can’t recognize a word if a letter is missing.
- Letter and symbol reversal issues: Kids with these issues switch letters or numbers when writing or make letter substitutions when reading after age 8. They also have trouble with letter formation that affects reading, writing and math skills.
