Aphantasia Beginner's Guide
Aphantasia is the inability to generate visual images, meaning people with the condition can understand concepts like “beach” but cannot see them in a mind’s eye, and the condition may also affect other sensory imaginations. The guide offers a simple “Apple Test” and references the VVIQ to help users determine their position on the visual imagination spectrum, while providing experiments, community links, and scientific background.
