This article explains how dyslexic children learn to read and suggests that pictures and sounds have a beneficial effect on a child's ability to read. A study was performed at the Children's Hospital in Boston, Massachusetts that test the brain activity in dyslexic and non-dyslexic children while playing a computer game that had sound and pictures.
Dr. Nadine Gaab, an assistant professor of pediatrics, suggests that children, as young as infants, 'have problems with processing these changes in sounds'. For example some cognitive neuroscientists suggest that dyslexic children have a problem with interpreting syllables like "ba" and "da". To test this Dr. Gaab had children play a “computer program that plays fast-changing and slow –changing sounds” and the children were monitored with an fMRI.
Results showed that dyslexic children use the same area of the brain to process both sounds and non-dyslexic children use over 11 areas extensively when processing the fast sounds.
fMRI “Magnetic resonance imaging (MRI) uses radio waves and a strong magnetic field rather than X-rays to take clear and detailed pictures of internal organs and tissues. fMRI uses this technology to identify regions of the brain where blood vessels are expanding, chemical changes are taking place, or extra oxygen is being delivered.”
