What Causes Dyslexia? Understanding Disorientation and Dyslexic Perception

By Ronald D. Davis

Original article from the Dyslexic Reader 2002: The following is a description of an experiment he conducted in 1982 to prove to himself that disoriented perceptions are a natural function of the brain. This understanding of how the use of a natural brain function not only produces the symptoms of dyslexia, but also the many talents dyslexic thinkers can exhibit, serves as one of the foundations of Davis Mastery for Dyslexia®. It explains the tools which allow dyslexic thinkers to intentionally control the distorted perceptions that are a product of disorientation—to both eliminate a learning disability and to enhance their talents.

Setting the stage: 1982

In 1982, after my colleagues and I had arrived at a basic, rudimentary understanding of what had to be done to correct dyslexia, we offered a program for doing so to the public. The program was producing spectacular results, and we gathered a great deal of empirical evidence to support it. But the program and I were being criticized and ridiculed by the established authorities on dyslexia. This was because the developmental model for dyslexia was such a major departure from the structural model (brain damage or malfunction) that was accepted at the time. In addition, I lacked any formal training or credential in the field, so I was quickly branded a kook or snake oil salesman.

I searched in vain for anything that would support the concept that distortion in perception was at the root of dyslexia symptoms. I couldn’t even find a simple explanation of perceptual distortion, why it happened, how it happened, or what it was called.

The motivation

My primary motivation was to establish that dyslexia was not the result of brain damage or malfunction. I wanted to find a way to prove that all of the symptoms of dyslexia could be produced by a normal brain functioning naturally. I felt that if I could make a link between the perceptual distortions, which even non-dyslexics experience, and dyslexia symptoms, it would prove that the symptoms of dyslexia were not evidence of brain damage or malfunction. I didn’t know where to begin.

The breakthrough moment

Then one day I was driving into the office. We had just had about two weeks of cold, gray, rainy weather.

That morning it was warm, bright, and sunny. I wanted to play hooky from work and go for a drive in the redwood forest. I was stopped at a stoplight, with my mind already in the redwoods, when suddenly I felt that I was going to bump into the car in front of me. I naturally pushed harder and harder on the brake but I wasn’t stopping. Suddenly I realized, it’s not me moving, it’s the other car rolling backward towards me! A toot of my horn prevented a bump, but my mind began to race. This firsthand experience of the phenomenon (distorted sensory perceptions) I had been talking about for months caused a shift in my perspective. If I could reproduce this same effect in a controlled situation, I might be able to prove my theory.

The experiment begins

That day I set up an experiment. The equipment was an old 33-1/3 speed record player, standing on its side. Attached to the turn table was a large cardboard disk with a spiral painted on it. With a foot switch so the device could be turned on and off without using a hand, a stop watch, a tape recorder, and a clipboard, I was ready to explore perceptual distortion. I was the first test subject. I sat in front of the disk looking at the center of the spiral. A press of my foot, and the disk began to spin. In less than five seconds I felt the motion. The speed of the disk was so fast that the sense of motion was like flying down an endless tunnel.

The goal of the experiment was to produce dyslexia symptoms in a non- dyslexic brain. But before that could be established, the equipment had to produce dyslexic symptoms in a dyslexic brain. Based on the developmental model, the symptoms of dyslexia came from distortions in the senses. The senses most affected were vision, hearing, balance, motion, and time.

Phase one: Vision

The first thing I noticed performing the experiment on myself was that just before the feeling of movement began, the speed of the spinning disk appeared to slow down. This indicated that not only was my sense of motion distorting, but also my sense of vision.

Phase two: Balance

The second phase of the experiment was to stand in front of the disk balancing on one foot, turn the disk on, and try to maintain balance. I don’t recommend doing this without an assistant to turn the disk on for you and, more importantly, to catch you when you begin to fall–because you will fall over backwards. The spinning spiral definitely distorted the sense of balance.

Phase three: Time

The third phase was to sit in front of the stationary disk with a stopwatch in hand. While looking at the center of the spiral, I tried to estimate the passage of fifteen seconds by clicking the stopwatch on, and when I thought fifteen seconds had elapsed, I clicked it off. In five attempts I was never more than three seconds off. The next part was to start the disk spinning, and try the same thing. In five attempts I never got closer than five seconds, and twice I was more than ten seconds off. My sense of time was definitely distorting.

Phase four: Hearing

The fourth phase was to turn on the tape recorder, spin the disk, and after the feeling of motion began, have an assistant say something to me, and repeat back what I heard. We used nursery rhymes like, “Sally sells sea shells at the sea shore.” Only the assistant would deliberately alter the words, like, “Sally tells sea snails at the sea shore.” Or, “Sally sells seashores to seahorses.” I could not hear exactly what the assistant said, and the proof was on the tape.

Testing a Hundred People

So with less than $100 of equipment, I demonstrated for myself that my brain distorted the senses of vision, hearing, balance, motion, and time. The experiment produced dyslexic symptoms in a dyslexic brain. Now I was ready to try the same thing on a non-dyslexic brain. I decided to put one hundred people through the steps of the experiment. I wouldn’t even attempt to pre- determine whether or not they were dyslexic. I wanted a cross section of the population.

I started doing the experiment with anyone who was willing to sit in front of the spinning disk. I soon discovered that I needed another piece of equipment – a plastic-lined waste can. I also discovered that I needed to change the protocol. At first I let others observe someone going through the experiment. Their observations influenced their own experience. So observation was permitted only after having had the experience.

Some people were made too nauseous by the spinning disk to complete all four phases of the experiment. But there was perceptual distortion in the phases they did complete. And everyone who completed the series experienced distorted vision, hearing, balance, motion, and time. Age, intelligence, education, gender, race, etc. didn’t matter–the results were consistent.

Then one evening a young woman, the forty-eighth test subject, was sitting in front of the spinning disk. She sat there on the verge of vomiting for about three minutes, then fell to the floor and had a grand mal seizure. The unexpected event scared me; it terrified her. She had never had a seizure before, and I had never seen one that up close and personal. I felt responsible for making it happen.

I had satisfied my own curiosity. I had nearly fifty test results, all of which confirmed my theory. After all, I didn’t have a graduate degree hanging in the balance. I concluded that I had proven my point, so the hundred person experiment ended at only forty-eight.

Talents which can be enhanced by disoriented perceptions

  • Spatial awareness and design
  • Strategic planning and problem-solving
  • Mechanical and engineering work
  • Creative fields like art, music, and drama
  • Athletics and piloting
  • Inventing and storytelling

Thus, the goal of Davis Orientation Counseling is not the elimination of disorientation, but the ability to consciously control it when it acts as a barrier to reading, writing, doing arithmetic, or succeeding in a traditional educational setting.
