Visual processing speed allows one to quickly interpret visual information and make split-second decisions. Visual processing can be thought of as 'visual reaction speed'. Visual processing speed allows one to keep up with the pace of the class, engage in sports and be a safe driver. Poor visual processing abilities require one to slow down and have repeated presentation to understand visual concepts.
The brain, not the eyes, processes the visual world, including things like symbols, pictures, and distances. This type of processing challenge involves trouble with processing information the eyes see. If a person with visual processing issues is reading a book, he may have trouble processing the words he "sees" on a page. That may be why some people confuse visual processing issues and dyslexia.
the ability to be aware of the distinctive features of forms, including shape, orientation, size, and color. Good visualization helps keep us from getting confused.
For example, visual discrimination allows a person to see the word "was" and "saw" are different even though they have the same letters.
the ability to understand directional concepts that organize external visual space. These skills allow a person to develop spatial concepts, such as right or left, front or back, and up or down as they relate to the body and to objects in space. A visual spacial deficit may contribute to poor athletic performance, challenges with rhythm, lack coordination and balance, letter reversals such as b and d's. There is also a tendency to work with one side of the body compared to using laterality or both sides.
the ability to recognize objects as the change in shape, size or orientation. Individuals may struggle to identify objects when turned in a different direction or viewed from a different point in space. Individuals may fail to recognize words they know that are presented in a different manner, like a book or on the board in school.
the ability to distinguish an object from a busy background. Individuals with poor figure-ground are easily frustrated or overwhelmed on a page with a lot of words. The person simply gets lost in the details.
the ability to recognize a complete feature from a fragmented piece like in a puzzle. This skill helps individuals read and comprehend quickly, the eyes do not have to individually process each word to quickly recognize the word by sight. Confusion of similar objects or words with close beginning and ending is common.
the ability to retain information over a period of time. This type of memory is for the immediate recall of given characteristics of a given object or form. Individuals with poor visual memory struggle with comprehension, softly whisper to themselves as they read in order to help compensate auditorially, difficulty in what a word looks like and take longer to copy text.
the ability to remember forms letters or characters in the correct order. This skill is important in spelling. Letter omissions, additions are common for those who struggle with this skill. Recognizing and remembering patterns may also be a problem.
Many educators consider letter reversals after the age of seven to be a symptom of dyslexia. While this can be true, the most common cause of reversals among older children is the lack of visual-spatial development. Not knowing their relationship to their own bodies or in the real world around them. The concept of laterality and directionality is hard.
A behavioral optometrist will conduct a visual processing assessment prior to the start of a vision therapy program. The visual processing assessment is a specific, age-appropriate, research-based test used to identify how an individual perceives and processes visual information. Diagnosing the 8 specific visual processing categories allows a treatment plan to be prescribed, then successfully treating the vision disorder and also working on low visual processing skills.
The vision therapist or behavioral optometrist will introduce vision therapy tools, games and/or activities for an individual to incorporate along with their vision therapy program.
