Study claims green screen filters can help dyslexic kids read faster

Make way for yet another milestone in the field of education and technology by the researcher. Scientists have come up with a study that using green filters on computer screens can help children with dyslexia read faster. That particular filters had no effect on age-matched children without dyslexia, researchers said. The colored filters for the treatment of learning disabilities were first patented in 1983. They were also designed for use by children with autism and attention deficit hyperactivity disorder (ADHD). "However, studies of their efficacy were methodologically flawed. We used a highly rigorous methodology for the first time," stated Milena Razuk, the one who performed the experiment during a research internship at Paris Diderot University in France. Eighteen children with dyslexia and 18 without dyslexia were selected for the study at Robert Debre Hospital in Paris.

The scientists have even claimed that they will be using yellow and green filters in the experiment. "Twelve colours are available, but we chose two because a very long test would be too demanding for the volunteers," stated Jose Angelo Barela, a professor at Sao Paulo State University in Brazil. All 36 children were asked to read passages from children's books suited to their reading age. The texts were displayed on a computer screen with a yellow filter, a green filter, and no filter.

As per the reports by PTI, Their eye movements were recorded with an eye-tracking device certified for medical purposes, consisting of goggles fitted with cameras that record the movements of each eye independently via infrared light signals. "A child with dyslexia has to fix his or her gaze on the words for a longer time to understand a text. Reading speed is slower as a result," Barela claimed.

While the channels did not influence perusing speed for the youngsters without dyslexia, there was a measurably huge distinction for kids with dyslexia. The last read quickest with the green channel, settling their look on gatherings of words for 500 thousandths of a second, contrasted and 600 thousandths of a second utilizing the yellow channel or no channel. The obsession time frame with or without channels was 400 thousandths of a second for kids without dyslexia. Scientists stretch that they didn't assess whether the utilization of a green channel enhanced cognizance of what was perused and that further research is expected to investigate this measurement.

The causes of dyslexia are unknown. In addition to reading difficulties, other deficits have been found to be associated with the disorder, including impaired sensorimotor integration. "It's as if some source of noise disturbs the brain's communication with the rest of the body," Razuk said. Extensive testing has shown that neither impaired eyesight nor intellectual deficiency is part of the condition. The improvement in reading time with the green filter might be due to changes in the visual stimuli available for central nervous system processing, researchers said.
