Aphantasia vs. hyperphantasia — the two ends of the imagery spectrum
Aphantasia and hyperphantasia are the two ends of the imagery spectrum — and both change how we think, dream, and remember.
While people with aphantasia can't produce inner imagery, people with hyperphantasia "see" their imagination as vividly as a real photograph. Both phenomena are more common than one might think — and both change how one thinks, dreams, and remembers.
Aphantasia
No inner image
- No visual image with eyes closed
- Knowledge about objects fully intact
- VVIQ score ≤ 32 (strict: VVIQ = 16)
Hyperphantasia
Images clear as a photo
- Extremely vivid, photorealistic images
- Hard to distinguish from reality
- VVIQ score 75–80
The VVIQ score as a measure
The VVIQ measures both extremes on the same scale — from 16 (aphantasia) to 80 (hyperphantasia).
16–32
Aphantasia
33–48
Below average
49–66
Average
67–74
Very vivid
75–80
Hyperphantasia
The VVIQ is subjective — two people with the same score can experience their images differently. Still, it's the best validated self-report instrument available.
What sets the two groups apart — everyday life
The same everyday situation — two completely different experiences.
Aphantasia:
Plot, dialog, concepts are central. Long landscape passages can be tiring.
Hyperphantasia:
Books feel like a film — mental castings and settings appear automatically.
Aphantasia:
"I was in Lisbon, the food was good." Facts without imagery.
Hyperphantasia:
Cinematic re-enactment: sunlight, sounds, plates on the table.
Aphantasia:
Mental list of points, notes, possibly speaking aloud.
Hyperphantasia:
Full mental rehearsal — room, audience, and pauses experienced in advance.
What sets the two groups apart — risks and strengths
Both profiles come with specific advantages — and their own challenges.
Hyperphantasia — Strengths
- Creative visualization (artists, designers)
- Strong spatial memory
- Vivid dreams and intense aesthetic experiences
Hyperphantasia — Risks
- Hypersensitivity to distressing content (films, news)
- Increased susceptibility to flashbacks after trauma
- Sometimes difficulty separating imagination from reality
Aphantasia — Strengths
- Less distraction by involuntary images
- Often strong analytical and verbal thinking
- Good logical structuring
Aphantasia — Risks
- Potential emotional distance from autobiographical memories (SDAM)
- Difficulty with visualization-based therapy approaches
Can these states change?
Both aphantasia and hyperphantasia are usually stable over a lifetime. There are very rare reports of changes after brain injury, stroke, severe depression, or neurological illness — but no known methods that reverse or induce these states in healthy people.
Short-term altered imagery during meditation, psychedelics, or hypnosis is anecdotally described but usually doesn't persist.
Both states are generally stable over a lifetime.
Important note
Neither aphantasia nor hyperphantasia are illnesses. Both are variations — no value judgments. Those who recognise themselves in one of these profiles don't need treatment, but understanding of their own way of thinking.
Frequently Asked Questions
Can someone have both at the same time?
Not in the same modality. Someone with visual aphantasia doesn't have visual hyperphantasia. But it's possible to have aphantasia in one sense (e.g., visual) and very vivid imagery in another (e.g., auditory).
Is hyperphantasia better than aphantasia?
No — both are variations, not value judgments. Hyperphantasia can be creatively advantageous but also carries risks (flashbacks, sensory overload). Aphantasia is not "deficient" but a different way of thinking.
Which test measures both extremes?
The VVIQ covers the entire spectrum. A score ≤ 32 suggests aphantasia (strict VVIQ = 16), ≥ 75 suggests hyperphantasia. The test is free at aphantasie.org/en/tests/vst.
Are hyperphantasia and eidetic memory the same?
No. Hyperphantasia is the ability to visualize very vividly — usually voluntarily. Eidetic memory ("photographic memory") is the ability to briefly reproduce a perceived image exactly. True eidetic memory is extremely rare and primarily documented in children.
Where are you on the spectrum?
The VST-16 test measures both aphantasia and hyperphantasia on the same scale. 5 minutes, instant result.
