SynQuiz vs ColoriDisc

SynQuiz is an app that contains four playful tests for synaesthesia. Synaesthesia is a neurodevelopmental trait estimated to occur in about 4% of the general human population. For people with synaesthesia two or more senses appear to be interconnected; for example a synaesthete perceives certain concepts, such as letters, numbers, days of the week, or months of the year as inherently coloured. Many synaesthetes are not aware that their perceptions are unusual and are often surprised to find out that others do not think of letters, numbers, or weekdays in colours. SynQuiz tests this type of synaesthesia, frequently referred to as grapheme-colour synaesthesia. The first three short quizzes are designed to give you a taste of what synaesthesia might be like and find out whether you might be experiencing it yourself. The fourth full test for letters & numbers gives an indication whether your type of synaesthesia is suitable for the ongoing genetic studies at the Max Planck Institute for Psycholinguistics. If so, you can directly apply and you may be invited later to provide a small sample of saliva (from which we can obtain your DNA). SynQuiz is developed within the Language in Interaction project (a large language-brain research project), in which currently more interesting language apps are being developed. Features: - Three playful quizzes testing synaesthesia for 1) letters and numbers, 2) days of the week, or 3) months of the year. - One longer test for letters & numbers after which you can directly apply for participating in ongoing genetic studies - Post your test scores to social media - Languages: English, German and Dutch

Colori turns color perception into a beautiful game. Each round presents a mosaic of colored patches. Most share the same hue — but a handful are quietly, subtly different. Your task: find and tap every patch that doesn't belong. Easy to learn, surprisingly hard to master. HOW IT WORKS - A reference color fills the screen as a field of tessellated patches. - Hidden among them are target patches shifted in hue, lightness, or saturation. - Tap every target before time runs out. - The easier differences vanish quickly — the tricky ones linger, daring you to find them. - Miss too many and you lose a life. Run out of lives and the game ends. GETTING HARDER AS YOU GO Color differences start large and obvious, then shrink with each level. Your eyes must work harder and harder to pick out what your brain insists looks the same. GLOBAL LEADERBOARD How does your color vision compare? After each game your score is submitted to a worldwide ranking. Set a nickname, track your personal best, and see where you stand among players around the globe. THE SCIENCE BEHIND THE FUN Colori was developed by vision scientists at Justus-Liebig-Universität Giessen. Every game you play contributes — anonymously — to research on human color discrimination. You're not just playing; you're helping us understand how human color vision works. Play casually for a few minutes, or push for a top-10 score. Either way, you'll never look at colors quite the same way again.
