Longitudinal study of grapheme

A new study published in scientific journal Frontiers in Human Neuroscience provides an insight about the grapheme-color synesthesia. The people suffering from this disease find it difficult to identify the colors, brighter or the darker shades etc. Grapheme-color synesthesia is an actually quite harmless and caused by subtle differences in the brain. This could be possibly due to the stronger connections between centers for language and the. For this study the researchers followed 80 kids in order to determine where, when and how the actual associations between graphemes and colors develop. The kids were provided with the regular tests to identify the colors. The lead researcher Dr. Simner, a cognitive neuropsychologist who specializes in synesthesia, from the University of Edinburgh, UK explains, “This repeated testing of child synesthetes in real time allowed us to see for the first time that synesthetic colors emerge slowly during childhood, building up an incremental inventory of colorful letters and numbers.”
