Eye Movement Characteristics of Children with Developmental Dyslexia during Reading

Using eye movement recording technology, the eye movement behavior of children with developmental dyslexia and normal children in reading process was studied, and it was found that the eye movement of children with developmental dyslexia in reading process had obvious defects. The specific manifestations are: prolonged fixation time, increased fixation times, increased number of diplopia, shortened saccade distance, increased saccade times, prolonged latency period, and increased error rate of reverse saccade. Future research should further explore the causes of eye movement defects in children with developmental dyslexia in order to reveal the physiological and psychological mechanisms of developmental dyslexia.
