Percentage of Population

Hey Martha, you're right that many aphantasia studies involve small sample sizes, especially those conducted in lab environments. However, several larger studies are now converging around a 1-5% population estimate, with sample sizes ranging from 500 to over 5,000 participants. The variation in findings primarily depends on whether researchers use a strict definition of aphantasia (total absence of imagery) or a broader definition (including dim or vague imagery). The Vividness of Visual Imagery Questionnaire (VVIQ) is the most widely accepted tool for measuring these rates. Here are a few key population studies, including one with a multicultural sample: https://aphantasia.com/research/10.1016/j.concog.2021.103243 https://aphantasia.com/research/10.21203/rs.3.rs-1703706/v1 https://aphantasia.com/research/10.3389/fpsyg.2024.1454107 You can always explore more in our research library at aphantasia.com/research.
