The majority of people today know of a number of advances in research. One such advance over the olden' days is eye-tracking technology. The notion that people may use diverse eye motions once we read isn't just a new person, but while the apparatus used for tracking eye movements has improved.
It has already been used to see whether those with developmental dyslexia actually utilize different eye trailing motions compared to skilled readers. So can dyslexia be diagnosed by simply using eye-tracking equipment?
There is really quite a bit of evidence to suggest that dyslexics use quantitatively different eye motions. By way of example, the eyes will fixate for longer, and also the length of time that they blink is shorter.
In addition, they tend to go back within a word more often than ordinary readers. Yet, there could be other reasons for those differences such as an issue in recognizing and understanding the exact word.
More eye movements can also be a result of attentional issues, inadequate comprehension, medication, stress, etc… Differentiating between more physical causes of eye movements from developmental disturbances can be difficult.
The ideal thing about tracking eye movements and also the research is the fact that the readers are far more likely to see in exactly the same way as they do normally. As though reading, a poor reader will likely soon be much more stressed and nervous that may bias the outcome of any test.
