Choose a test to measure your visual and sensory imagination. All tests are free, anonymous, and follow methods from aphantasia research.
VST-16 – Visual Spectrum Test
Measures the vividness of visual imagery using 16 everyday scenarios.
The VST-16 is aphantasie.org's own self-test, drawing on the methodology of established imagery questionnaires (Marks, 1973). It contains 16 original items in 4 everyday scenes and measures how vividly you can picture scenes in your mind.
MST-21 – Multisensory Spectrum Test
Capture your imagination across all senses.
The MST-21 is aphantasie.org's own self-test, based on the PSI-Q research methodology (Andrade et al., 2014). It measures your imagination across 7 sensory modalities: vision, sound, smell, taste, touch, body sensation, and emotion.
Binocular Rivalry - Objective Test
ExperimentalExperimental test based on the priming effect in binocular rivalry.
This innovative test uses the scientific phenomenon of binocular rivalry. Unlike questionnaires, it provides objective data about your imagery ability that is less dependent on subjective assessment.
Hyperphantasia Test
Do you have exceptionally vivid, near-photorealistic mental images? This test uses the VST-16 (methodology of the VVIQ, Marks 1973) and shows whether your scores fall in the hyperphantasia range.
Hyperphantasia is the upper end of the imagery spectrum. This test uses the VST-16 (methodology modeled on the VVIQ, Marks 1973) and shows you whether your mental images are vivid enough to qualify as hyperphantasia (score above 70 out of 80).

What Does an Aphantasia Test Measure?
Aphantasia tests measure the ability to create mental images. People with aphantasia cannot visualize things – when they think of an apple, for example, they see no image in their mind's eye.
Visual imagery exists on a spectrum: from aphantasia (no images) through typical imagery to hyperphantasia (extremely vivid, almost photographic images). Most people fall somewhere in the middle.
Our tests help you find your place on this spectrum. This can be valuable for self-understanding, creative professions, or scientific research.
Frequently Asked Questions
What is aphantasia and how do I know if I have it?
Aphantasia is the inability to voluntarily create mental images. People with aphantasia see nothing in their mind's eye when asked to imagine something. Our tests help you find out if you're affected and to what degree.
Who are these tests suitable for?
The tests are suitable for anyone who wants to learn more about their imagery ability. They are free, follow established research methodology, and only take a few minutes. Especially interesting for those who suspect they visualize differently than others.
How accurate are the test results?
Our tests follow the methodology of internationally recognized questionnaires (VVIQ, PSI-Q), but contain original items and have not been separately psychometrically validated. They are self-assessments — for a clinical assessment, consult a professional.
