Frequently Asked Questions About Aphantasia

Aphantasia is the inability to voluntarily create mental images – also known as having a 'blind mind's eye'. People with aphantasia cannot visually imagine things: when they think of a sunset, they 'see' nothing, but they conceptually know what one looks like. The term was coined in 2015 by Professor Adam Zeman. It is not a disease, but a normal variation of human cognition. Learn more on our information page about aphantasia.

According to the largest study (Wright et al. 2024, n=9,063), approximately 0.9-1.2% of the population has pure aphantasia – complete absence of visual imagery. A further 3.3% or so have hypophantasia (significantly reduced imagery, also Wright et al. 2024). Combined, this gives the often-cited figure of around 4%. A study with a self-selected sample found an association between aphantasia and STEM careers (Zeman et al. 2020) – whether this reflects a true overrepresentation or sampling bias is unclear.

No, aphantasia is neither a disease nor a disability – it is not classified as a disorder in ICD-10/11 or DSM-5. The Cleveland Clinic describes it as not a medical condition, disorder or disability – rather as a characteristic, like being left- or right-handed. There is nothing to 'cure' or 'treat'. Many people with aphantasia lead successful lives and often only notice their uniqueness in adulthood. Learn more on our information page about aphantasia.

The boundary is fluid: research describes imagery as a spectrum. People who reach the minimum score of 16 on the VVIQ have no inner images at all (aphantasia in the narrow sense). People with only vague, dim images (VVIQ 17–32) are often described as hypophantasic; some studies count this group as aphantasia (Wright et al. 2024; Dawes et al. 2020). In both cases people know what things look like – only the inner image is missing or stays weak.

Yes. In a large survey, the majority of people with aphantasia reported visual dreams (Zeman et al. 2020). Others dream without images or hardly remember dreams; on average, people with aphantasia report fewer and less sensory dreams (Dawes et al. 2020). One possible explanation: dreams arise involuntarily and probably through different brain processes than voluntary imagery.

These terms figuratively describe what aphantasia means: the inability to 'see' with the 'mind's eye'. When people without aphantasia are asked to imagine a red apple, they 'see' it internally – sometimes sharper, sometimes blurrier. People with aphantasia see nothing in this situation – their mind's eye is 'blind'. But they can still know that an apple is red, round, and shiny – just without an image.

Since aphantasia is not a disease, there is no 'cure'. Some people report slight improvements through image streaming or meditation exercises; controlled studies on this are almost non-existent, and there are no proven methods. Many affected people use alternative strategies instead – and many don't experience their aphantasia as a disadvantage at all.

Although the phenomenon was described by Sir Francis Galton as early as 1880, British neurologist Professor Adam Zeman coined the term 'aphantasia' in 2015 (from the Greek 'a-' for 'without' and 'phantasia' for 'imagination'). The starting point was a patient who lost his inner images after a cardiac catheter procedure (coronary angioplasty) (Zeman et al. 2010). After a magazine article about the case, more than twenty people who had never had inner images got in touch (Zeman et al. 2015); after 2015, many thousands followed (Zeman et al. 2020).

Aphantasia is usually lifelong, but it can also be acquired later in life. According to the data so far, the lifelong (congenital) form is considerably more common than the acquired one (Knowles, Jones & Zeman 2021). Many people only realize as teenagers or young adults that other people really do see images in their mind (Zeman, Dewar & Della Sala 2015). Acquired aphantasia has been described after head injuries, strokes and other brain damage, but also in connection with mental illnesses such as depression (Zeman 2024). In an analysis of 88 cases of acquired aphantasia, the site of damage was rarely known; where it was, it was mostly in posterior brain regions involved in visual processing (Knowles et al. 2021). Partial improvement has been described in individual cases (Bumgardner et al. 2021).

A good first step is our VST-16 test (Visual Spectrum Test). It is modelled on the VVIQ (Marks, 1973) and contains its own items. If you consistently choose the lowest values (1 out of 5 – 'No image'), this matches the pattern that VVIQ studies classify as aphantasia; it is not a diagnosis. For a picture across all senses, we also recommend the MST-21 test.

The VVIQ (Vividness of Visual Imagery Questionnaire) is the best-known scientific questionnaire for measuring visual imagery (Marks 1973, used in numerous studies). You are asked to picture various scenes and rate their vividness on a scale of 1–5. A total score of ≤ 32 (out of 80) is the research convention for aphantasia (Dance et al. 2021, 2022; Dawes et al. 2020; Keogh et al. 2021; Wicken et al. 2021; the boundary is arbitrary, Blomkvist & Marks 2023). Marks makes the questionnaire freely available; you can fill in the original, in its English wording, for free on our VVIQ page. There is also our own VST-16 test, with the same structure and its own items.

The PSIQ (Plymouth Sensory Imagery Questionnaire, Andrade et al. 2014) is more comprehensive than the VVIQ and measures imagery across seven modalities — visual, auditory, olfactory, gustatory, tactile, bodily and emotional. Our MST-21 follows this methodology with original items. Test all your senses with the MST-21 test.

The Binocular Rivalry test does not rely on self-assessment. Each eye is shown a different image – typically a red and a green pattern. People who first imagine one of them vividly then perceive it as dominant more often (Pearson et al. 2008). At group level, people with aphantasia show hardly any of this effect (Keogh & Pearson 2018). For classifying an individual, however, the effect is too small (Monzel et al. 2025); our home version is experimental and not validated.

There is no standardized medical test or formal 'diagnosis' for aphantasia, as it is not classified as a disorder. Assessment is mainly based on self-report questionnaires like the VVIQ and PSIQ — both validated research instruments. Our self-tests VST-16 and MST-21 follow their methodology and offer initial orientation.

A doctor's visit is usually not necessary if you've always been this way. BUT: if your visual imagery has suddenly disappeared (after trauma, surgery, stroke, or illness), you should definitely consult a neurologist – this could indicate acquired aphantasia or other neurological problems. Otherwise, aphantasia is not a condition requiring treatment.

The VVIQ and PSIQ are psychometrically tested questionnaires used in research worldwide. Our own tests VST-16 and MST-21 are modelled on them but contain their own items and have not been separately psychometrically validated. They offer initial orientation. There is no official diagnosis of aphantasia; if you want a professional assessment, you can turn to a neuropsychologist.

Yes, misjudgements are possible in both directions. Some people wrongly believe they have aphantasia because they take "visualizing" too literally and expect photorealistic images – many people have rather vague, fleeting images. Conversely, people with aphantasia often don't recognise their difference for a long time because they never knew that others really "see". Confusion with SDAM (Severely Deficient Autobiographical Memory) or prosopagnosia (face blindness) occurs. Imagery can also weaken in connection with depression (Zeman 2024). If unsure, a neuropsychologist can help; repeating a self-test at different times can also bring clarity.

No, not necessarily. Many creative people have aphantasia, including Ed Catmull (Pixar co-founder) and Blake Ross (Firefox co-creator). People with aphantasia often use other strategies for creative thinking: conceptual thinking, verbal descriptions, or working directly with the medium (sketches, prototypes). More on our page about living with aphantasia.

Yes! Many people with aphantasia are avid readers. The reading experience works differently: instead of seeing 'movies in their head', aphantasics understand the story on a conceptual, emotional level. Some report that detailed visual descriptions appeal to them less than plot- and character-driven stories. Interestingly, some successful authors are themselves aphantasics.

People with aphantasia often experience remembering differently: instead of visually 're-living' past scenes, they tend to remember facts about the event. In the first study, 14 of 21 participants reported difficulties with autobiographical memory (Zeman et al. 2015), and people with aphantasia recalled fewer details (Dawes et al. 2022). A particularly severe, lifelong form is called SDAM (Severely Deficient Autobiographical Memory, Palombo et al. 2015) – but that is not the same as aphantasia. Factual knowledge is typically not impaired. Many use diaries or photos as support.

Yes, most people with aphantasia recognise faces. You recognise someone even if you can't call up their face 'in your mind's eye'. In a large survey, however, people with aphantasia reported difficulties with face recognition more often (Zeman et al. 2020), and many find it hard to describe the face of someone who isn't present. This is not the same as prosopagnosia (face blindness).

Some possible advantages are reported: in a lab experiment, people with aphantasia had fewer visual flashbacks (Keogh, Wicken & Pearson 2023, Preprint) – but this is not proven protection against PTSD as a disorder, since non-visual and emotional distress can still occur. When reading frightening stories, they showed a weaker bodily fear response (Wicken et al. 2021). Some also describe themselves as less distracted by unwanted images.

A proven explanation: 'When you imagine an apple, you see it in your mind's eye – sometimes sharper, sometimes blurrier. For me, it's different: I know everything about the apple – that it's red, round, and shiny – but I see absolutely nothing. My mind's eye is like a switched-off screen.' The 'Apple Test' is often a good conversation starter. More tips on our info page.

Yes, but differently than 'image-based' meditation. Many aphantasics successfully practice mindfulness meditation that focuses on body sensations, breathing, or sounds. Guided visualization meditations often don't work in the literal sense, but some use them conceptually. Yoga, body scan meditation, and breathing exercises are particularly suitable alternatives for people without mental images.

Aphantasia can have subtle effects: some partners feel hurt when the aphantasic says they can't picture their face. Communication is key: it doesn't mean you love or miss them less – you just experience it differently. People with aphantasia often miss others just as intensely, just without the visual component. Knowing about aphantasia can resolve misunderstandings and lead to deeper mutual understanding.

Several well-known people have spoken publicly about their aphantasia. Pixar co-founder Ed Catmull told the BBC in 2019 that his mind's eye is “blind”. Firefox co-creator Blake Ross described in a widely read 2016 Facebook post that he has never visualized anything. Genome researcher Craig Venter reported in 2020 that he has aphantasia (University of Exeter press release). Beyond well-known names, people with aphantasia work in mathematics, computer science and the natural sciences more often than average (Zeman 2024).

Current research shows that aphantasia cannot be explained simply as poor self-assessment. The Binocular Rivalry test provides evidence that does not rely on self-report – groups with aphantasia show little imagery priming on average, though the effect is too small to classify an individual (Monzel et al. 2025). The pupil, too, hardly responds to imagined bright or dark scenes in aphantasia (Kay et al. 2022). At rest, coupling between the prefrontal cortex and the visual network is weaker (Milton et al. 2021); during remembering, coupling between the hippocampus and the visual cortex differs (Monzel et al. 2024). The 'Vision in Reverse' hypothesis describes imagery as top-down activation of the visual cortex – exactly how this differs in aphantasia is still open.

It is not always just vision that is affected. About 26% of people with visual aphantasia report no imagery at all in any of the other senses either (Dawes et al. 2020); the remaining ~74% still have imagery there, but on average weaker. Sounds, smells, tastes, touch, bodily sensations and feelings can be affected – the 7 areas covered by the PSI-Q, for example (Andrade et al. 2014). A complete absence of imagery in all senses is therefore not rare in aphantasia.

Yes, aphantasia occurs in families more often than would be expected by chance (Zeman et al. 2020). A first estimate found a roughly tenfold increased likelihood for siblings; it is based on self-reports about relatives and has not been replicated. This points to a genetic component, but specific genes have not yet been identified.

Hyperphantasia is the opposite of aphantasia: an exceptionally vivid, detailed imagery ability. People with hyperphantasia describe inner images that feel almost as clear as actual seeing – on the VVIQ this corresponds to scores of 75–80 (Wright et al. 2024). Imagery forms a spectrum from aphantasia through typical imagery to hyperphantasia. Learn more on our hyperphantasia page.

While classic aphantasia concerns visual imagination, some people have extended or 'total' aphantasia that also encompasses other senses: they cannot mentally 'hear' sounds either (auditory aphantasia), 'smell' scents, or 'feel' touches. The PSIQ test can help determine which senses are affected. Learn more about the different forms of aphantasia.

Aphantasia research has boomed since 2015. Current focus areas include: neuroimaging studies (fMRI) to understand brain activity; genetic studies on heritability; connections with memory and SDAM; objective tests like Binocular Rivalry; and prevalence studies in different populations. Leading research groups exist at the University of Exeter (Prof. Zeman), UNSW Sydney, and other institutions worldwide. More on our research page.

There are indications of slightly elevated autistic traits in people with aphantasia: Dance et al. (2021) found higher average AQ scores (Autism-Spectrum Quotient) in an aphantasia sample, especially on the imagination and social skills subscales; Milton et al. (2021) likewise reported autistic traits more often in their aphantasia group. The evidence is mixed, however — Dupont et al. (2024) found no AQ differences in a small sample (14 people with aphantasia, 14 controls), and Bouyer et al. (2025) found only a weak association between AQ scores and imagery vividness across several surveys. Looking at it the other way round, King et al. (2024) found in an online survey of 121 adults that autistic participants reported lower average imagery vividness than non-autistic participants (d = −0.44). Hard percentages for an increased autism diagnosis rate are not supported by current research. Aphantasia and autism remain independent phenomena: most people with aphantasia are not autistic and vice versa. Shared neurological foundations — such as differences in connectivity between frontal and sensory areas — are currently being researched; robust conclusions are still lacking. An aphantasia self-test says nothing about an autism diagnosis. More: aphantasia and autism

Not demonstrably. In a small study (69 people), the IQ of the aphantasia group (mean 115) was significantly higher than that of the hyperphantasia group (106), but not demonstrably higher than that of the control group (110) (Milton et al. 2021). A general link cannot be derived from such a small sample. There is no evidence of lower intelligence; if anything, average IQ is slightly higher with aphantasia than with hyperphantasia (Zeman 2024). In an early survey, 14 of 21 people with aphantasia described compensatory strengths in verbal, mathematical or logical areas (Zeman, Dewar & Della Sala 2015). More: aphantasia and intelligence

Aphantasia hardly limits career choices – successful aphantasics work in almost all fields, including visually creative professions. However, many affected people report strengths in analytical areas: programming, science, mathematics, law, engineering. Ed Catmull, co-founder of Pixar, is a famous example that even animation is possible. The key often lies in working with external aids rather than internal images.

Although there are no specific 'aphantasia apps', many affected people use the following strategies: extensive photo documentation (memory aid); vision boards and mood boards (external visualization); text-based notes instead of mind maps; 3D modeling software for spatial thinking; voice memos for ideas. Tips for strategies like these are shared in the communities listed in our answer about connecting with others.

Whether image-based memory techniques (memory palace, visual mnemonics) work less well with aphantasia has barely been studied; one study found no disadvantage with imagery-based memorization instructions (Thomas et al. 2022, Memory & Cognition). If image-based techniques don't work for you, you can try alternative strategies: verbal repetition and stories; categorization and logical connections; written notes and lists; spaced repetition apps (Anki); linking with emotions or body sensations; audio recordings. Experiment to find out what works best for you.

When a therapist or instructor offers visualization exercises, open communication is important. Explain your aphantasia and ask for alternatives: instead of 'Imagine a safe place', it could be 'Describe or think about the qualities of a safe place'. Many exercises can be adapted to conceptual or body-focused approaches. A good therapist will be able to adjust.

Aphantasia itself does not cause mental health conditions. However, realizing you're 'different' can initially be unsettling. In a lab experiment, people with aphantasia showed fewer visual flashbacks (Keogh, Wicken & Pearson 2023, Preprint) – but this is not proven protection against PTSD as a disorder; non-visual and emotional distress can still occur. If you're seeking support, talking to others who share the experience can help – connecting with others who share the experience is often found to be very valuable.

You're not alone! There are actively maintained communities internationally: the Aphantasia Network website with its Facebook group, Reddit r/Aphantasia, and local meetup groups in larger cities. Connecting with others who share the experience can be very enlightening – many report 'aha moments' when they share experiences.

Whether image-based memory techniques such as memory palaces work less well with aphantasia has barely been studied; one study found no disadvantage with imagery-based memorization instructions (Thomas et al. 2022, Memory & Cognition). If image-based techniques don't work for you, language-based strategies can help: acronyms, word-based mnemonics, rhythmic repetition or reading aloud, as well as text-based flashcards. In mathematics, formal notation and written-out calculation steps can be an alternative to geometric imagination. It can also help to let teachers know that prompts like “imagine…” cannot be carried out visually by some learners. Incidentally, people with aphantasia work in mathematics, computer science and the natural sciences more often than average (Zeman 2024).
