01Starting point
Aphantasia – the inability to form mental images – is unknown to many who have it. There was no serious, accessible starting point in several languages that is honest about what a self-test can and cannot do.
02Approach
- 01Our own self-tests following research methods, every item in our own words; plus the original VVIQ with attribution.
- 02Every figure and source checked against primary literature, consistent across all five languages.
- 03Relaunched as a “darkroom”: a custom WebGL shader develops a print as you scroll, and each scene photo sharpens with your answer.
- 04No accounts, no database: results stay on the device or in the share link.
03In detail
The seven self-tests
Among them the original VVIQ (Vividness of Visual Imagery Questionnaire, David Marks, 1973), a multi-sensory test following the method of the PSIQ (Plymouth Sensory Imagery Questionnaire), a binocular rivalry test and questionnaires on hyperphantasia, autobiographical memory and inner monologue. With psychological tests, fidelity to the source decides the value of the result: sources are listed on the test pages, and the items of the originals stay unchanged.
Five languages from the start
Each language version has its own address, its own metadata and hreflang links so search engines recognise them as one set. Because routing was built per language from the beginning, adding Spanish, French and Polish later was a matter of translation, not architecture.
3D that stays optional
“Through the Mind’s Eye” shows in five stations what aphantasia means: a glowing apple fades, flickers, disappears and becomes a constellation – driven by scrolling, rendered with Three.js and React Three Fiber. Visitors with reduced motion or without WebGL get a simplified version; the portal works fully without 3D.
Load time
0.97 s until content is visible (LCP, Lighthouse desktop, median of 3 runs, 30 Sep 2026) – a lab measurement, not field data from real users.
04Outcome
#1 on Google for “aphantasie test” and a test portal in five languages that is honest about what a self-test can do – it shows how design, motion and verified content work together.
