Synaesthetes ‘taste’ sound for example, or more common, they perceive certain concepts, such as letters, numbers, days of the week or months as inherently coloured. The new app SynQuiz, from Radboud University, contains four playful tests for synaesthesia. The app is available at the App Store and the Google Play Store (for smartphones and tablets).
Synaesthesia researchMany synaesthetes are not aware that their perceptions are unusual and are often surprised to find out that others do not think of letters or numbers in colours. SynQuiz tests this ‘grapheme-colour’ synaesthesia. The first three short quizzes in the app are designed to give a taste of what synaesthesia might be like and to find out whether you might be experiencing it yourself.
The longer letters/numbers test gives an indication whether your type of synaesthesia is suitable for the ongoing genetic studies. If so, the researchers might invite you to provide a small sample of saliva, from which they can obtain your DNA.
SynQuiz is based on a research programme in the Language and Genetics Department at the Max Planck Institute for Psycholinguistics, based at Radboud University campus in Nijmegen, the Netherlands.
