children with visual discrimination problems

Poor visual discrimination skills are often mistaken for symptoms of dyslexia

Does your child struggle with reading? Have you noticed your child reversing letters? If so, you and your child’s teachers may suspect dyslexia. However, an undetected vision problem that can be treated with vision therapy could actually be to blame for letter reversals and other common learning problems.

Dyslexia is a language-based learning disability that causes difficulty with reading, writing, and spelling. Reversing letters is one of the most familiar tell-tale signs of dyslexia, but letter reversals are common among children with treatable vision problems too.

People with dyslexia learn differently, and while they are often able to adapt and overcome the challenges they face, it is a condition that can’t be reversed.

Visual discrimination is a perceptual process involving our ability to correctly identify distinctive features of a visual stimulus, such as text. Visual discrimination skills enable a child to see and identify size, color, shape, and orientation.

Poor visual discrimination skills cause a child to have difficulty with directionality or laterality. With poor directionality or laterality skills, a child is unable to distinguish left from right on themselves, which causes them to have trouble distinguishing left from right on other objects, including letters and numbers.

For example, they will confuse b with d or q with p. They may also confuse b with p or d with q.

You will notice young children having trouble determining left from right, which is a normal phase of learning; but by the time a child reaches second grade, this skill should be fully developed. For those of us with a normal healthy visual processing system, this skill develops early and naturally. So if the child continues to confuse directions and reverse letters beyond second grade, they may need to undergo vision therapy to further develop the skill.

When visual discrimination isn’t functioning properly, similar letters and words will continue to be confused. In addition to directionality, they may confuse words that appear similar, such as “want” and “what.”

Without addressing this problem, deficient visual discrimination functions can be a lifelong challenge.

The good news is, unlike dyslexia and other learning disabilities, poor visual discrimination skills can be treated and improved significantly in a short period of time with vision therapy. Vision Therapy is a treatment program that includes exercises and procedures that are designed to enhance a child’s ability to control eye movement and visual processing.

What does it mean to have a visual processing problem?

A visual processing problem is a type of perceptual deficiency that hinders a child’s ability to make sense of information that they take in through their eyes. Reading, writing, learning and countless important everyday activities require strong visual processing skills.

To be able to see clearly is just the beginning, and 20-20 vision is not enough. It is the brain, not the eyes, that interprets and applies visual data. A visual processing problem occurs when there is a disruption or inefficiency in the way the brain processes information after the eyes see something.

Vision requires healthy neurological activity and communication between the eyes and the brain within a complex set of mechanisms. A visual processing problem results when this system either hasn’t developed properly or it has been damaged in some way.

When a child has a visual processing disorder, they may see clearly and their eyes may function normally, but they may not have the ability effectively and efficiently interpret, categorize, remember, or associate meaning with the images and information in their brain.

Examples of visual processing problems include difficulty with visualization, visual memory, visual processing speed and accuracy,  visual-motor integration and speed, and more.

Visualization is the process of creating a mental picture in the mind. It’s what occurs when someone says to “picture this” or when you’re reading and you imagine the characters and scene in your mind. This process is fundamental to creating and associating meaning. A child with a visualization problem struggles to create that mental picture, so they are missing an important building block of learning.

Visual memory refers to the ability to accurately remember something you see. We have to remember what letters look like, what words look like, and what letters and words mean from sentence to sentence, from page to page, and from day to day. If there is a problem with visual memory, learning of the same material has to occur again and again.

Visual processing speed and accuracy involves reading words, sentences, and numbers quickly and with few errors. Children with visual processing problems tend to work slowly and make more errors in their work.

Visual-motor integration is the ability to correctly perceive visual information, process it, and move your hands or body accordingly. Visual-motor speed is the ability to efficiently integrate visual skills and motor skills for the purpose of completing a task.

Visual sequencing is the ability to tell the correct order of words, symbols, or images.

Visual figure-ground discrimination enables a child to distinguish a shape or text from the background in which it is situated. Visual discrimination is the ability to recognize the difference between similar objects, shapes, or letters, such as p and q or b and d.

Visual closure is the ability to identify an object from its parts. For example, the child might not be able to identify a car that’s missing its wheels or a word missing letters, which interferes with learning, reading, and spelling.

Visual-spatial processing refers to the ability to tell space or distance of an object, either on paper or physically. It also enables understanding of time and narrative, which factors into comprehension levels.

If your child has a visual processing problem, school, athletics, and even social interaction can be challenging. The good news is visual processing therapy with one-on-one vision training can effectively improve visual processing skills.

Signs of visual processing problems include:

  • Difficulty reading
  • Complaints of tiredness while reading
  • Losing place or skipping words while reading
  • Trouble with math or inability to make progress in math
  • Messy handwriting
  • Difficulty buttoning or zipping clothes or trouble cutting food or using scissors
