Close your eyes and imagine a beach. If you can't "see" anything — just darkness — you might have aphantasia, the inability to form voluntary mental images.
The ability to form mental images exists on a spectrum. On one end, hyperphantasia — visualization so vivid it's confused with reality. On the other, aphantasia — the complete absence of voluntary mental images. The term was coined by neuroscientist Adam Zeman in 2015, at the University of Exeter.
Mental visualization spectrum
Based on the Vividness of Visual Imagery Questionnaire (VVIQ) — Marks, 1973
Aphantasia doesn't mean lack of imagination — it means imagining in a different way, without visual images in the mind.
Can't visualize the faces of loved ones, even after just seeing them.
Still recognizes people in personDoesn't form images of visited places. Can describe facts, but can't 'see' the scene.
Factual memory remains intactWhen asked to imagine an apple, no image appears — just the abstract concept.
Knows what it is, but can't visualizeReasoning works normally. Aphantasics think in concepts, words, and logic.
Intelligence is not affectedSome aphantasics dream with images, others don't. The experience varies greatly.
Research still ongoingAphantasia can also affect auditory, olfactory, and tactile imagination — or just the visual one.
Multisensory in some casesResearch on aphantasia is relatively new, but findings already reveal real differences in brain activity of those who don't form mental images.
After cardiac surgery, patient MX completely lost the ability to visualize mental images. This case motivated Adam Zeman to investigate the phenomenon.
Zeman and colleagues at the University of Exeter publish the study coining the term 'aphantasia', based on ancient Greek — a (without) + phantasia (imagination).
fMRI studies show that people with aphantasia exhibit reduced activity in the visual cortex during imagination tasks, with greater activation in cognitive control areas.
Recent research explores the relationship between aphantasia, autobiographical memory, creativity, and dreams. Universities in Australia, UK, and Canada lead the studies.
"Aphantasia is not a disorder — it is a fascinating variation in human experience that challenges fundamental assumptions about the nature of thought."
— Prof. Adam Zeman, University of Exeter
Having aphantasia doesn't mean having less cognitive ability. It's a natural variation in how the brain processes information — just like being left-handed or having synesthesia. Many people live their entire lives without knowing they think differently.
Created one of the largest animation studios in the world without being able to visualize images in his own mind.
Discovered he had aphantasia at age 30 and wrote a viral essay about the experience.
Responsible for iconic characters like Ariel and the Beast, described difficulties with mental visualization.
Aphantasics find their own ways to create, remember, and solve problems — using verbal, spatial, logical, and conceptual thinking. There is no "right" way to think.
