Study says green screen filters can help dyslexic children read faster

The researcher marks a new stage in the field of education and technology. Scientists have come up with a study that the use of green filters on computer screens can help dyslexic children read faster. These filters had no effect on children without dyslexia of the same age, researchers said. The color filters for the treatment of learning disorders were patented for the first time in 1983. They were also designed to be used by children with autism and deficit hyperactivity disorder. of attention (ADHD). "However, studies on their effectiveness presented methodological flaws.We used an extremely rigorous methodology for the first time," said Milena Razuk, the one who conducted the experiment during a research internship at Paris Diderot University in France. Eighteen children with dyslexia and 18 others without dyslexia were selected for study at Robert Debré Hospital in Paris

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

According to PTI reports, their eye movements were recorded with a certified medical eye tracking device consisting of goggles. equipped with cameras that record the movements of each eye independently via infrared light signals. "A dyslexic child needs to look at words longer to understand a text, so reading speed is slowed down," Barela said.

While the channels do not influence the reading speed of young people without dyslexia, there was a huge difference for dyslexic children. The latest readers have been reading faster with the green channel, staring at word gatherings for 500 milliseconds, contrasted and 600 thousandths of a second using the yellow channel or no channel. The temporal obsession with or without channels was 400 thousandths of a second for children without dyslexia. Scientists say they have not determined whether the use of a green channel helps to better understand what had been read and if further research should allow to study this. measured.

The causes of dyslexia are unknown. In addition to reading difficulties, other deficits have been badociated with the disorder, including impaired sensorimotor integration. "It's as if a source of noise was disrupting the brain's communication with the rest of the body," Razuk said. In-depth tests have shown that neither intellectual disability nor intellectual disability are part of the disease. Improved reading time with the green filter may be due to changes in visual stimuli available for treatment of the central nervous system, the researchers said.
