When someone says, “Imagine an apple,” what comes to mind You might see a vibrant pile of apples at a bustling market or a peaceful orchard with ripe apples scattered on the ground. For many, visualizing these scenes is second nature. But for others, especially those with a neurological condition known as aphantasia, forming mental images is impossible they simply cannot visualize the apple at all.
According to Professor Joel Pearson, a cognitive neuroscientist and director of the Future Minds Lab at the University of New South Wales, aphantasia represents a different way of processing the world. He explains that it's similar to solving a simple math problem everyone uses their own method, but they often arrive at the same answer.
Importantly, aphantasia is not a disorder or illness, and it doesn't require a cure. It’s just a unique cognitive style a variation in how the mind works, not a malfunction.
What Is Aphantasia?
The concept of mental imagery dates back to ancient times. Around 350 B.C., Greek philosopher and polymath Aristotle introduced the term phantasia to describe what we now refer to as the “mind’s eye” essentially, imagination. Fast forward nearly 2,000 years, and in 2015, Professor Adam Zeman, a cognitive and behavioral neurologist at the University of Exeter in the U.K., coined the term aphantasia to describe the inability to visualize mental images a condition now recognized in the field of neuroscience.
Zeman first encountered a patient in 2003 who reported losing the ability to visualize mentally. This sparked his interest and led to deeper investigation. Through brain imaging studies, Zeman observed that when most people visualize an object, a specific brain region becomes active. However, this region remained inactive in his patient’s case.
Originally described as a form of “blind imagination,” Zeman’s discovery gained attention, prompting others to come forward with similar experiences many stating they had never been able to form mental images at all. His groundbreaking study, Lives Without Imagery: Congenital Aphantasia, laid the foundation for ongoing research, yet the neurological mechanisms behind aphantasia remain only partially understood, leaving much more to uncover.
How Many People Have Aphantasia?
It’s estimated that about 3 to 4 percent of the population lives with aphantasia the inability to visualize images in the mind’s eye. Yet, many people with the condition don’t even realize they experience the world differently. As a result, the actual number of individuals with aphantasia could be significantly higher than current estimates suggest.
Take Ian James, a water engineer, who discovered he had aphantasia only in his mid-50s. Until then, he had no idea that the way he processed thoughts differed from those around him. Like many with aphantasia, Ian knows what an apple looks like, but when asked to visualize it, he draws a blank.
Can People with Aphantasia Dream?
Even among people diagnosed with aphantasia, experiences can vary widely particularly when it comes to dreaming. While many individuals with aphantasia dream only in words or abstract concepts, others report having vivid, lifelike dreams complete with detailed imagery. This difference exists because dreaming taps into distinct regions of the brain, some of which may not be impacted by aphantasia.
One common challenge for those with aphantasia is the inability to recall visual memories. Moments from childhood, past vacations, or emotional events may feel harder to access because the visual component is missing. Instead of "seeing" the memory, they may only recall facts or feelings.
Interestingly, this lack of mental imagery can have unexpected benefits. For example, people with aphantasia are often less affected by scary or disturbing content, such as horror movies. Since they can’t easily recreate frightening scenes in their mind later, they’re less likely to relive the fear through nightmares or flashbacks.
Testing for Aphantasia
When it comes to the mind’s eye, there’s no universal method for testing how vividly someone can visualize. Mental imagery exists on a broad spectrum ranging from complete absence of imagery to incredibly vivid, almost lifelike mental scenes.
One of the most widely used tools for assessing visual imagination is the Vividness of Visual Imagery Questionnaire (VVIQ). Developed in 1973 by British psychologist David Marks, the VVIQ remains a foundational assessment in mental imagery research. It asks individuals to rate how clearly they can imagine specific scenarios, helping to categorize where they fall on the visualization spectrum.
Despite growing awareness of aphantasia, scientific research on the condition is still in its early stages. There remains a significant gap in understanding how and why aphantasia develops, how it influences different aspects of cognition, and how it varies across individuals. As interest in the topic grows, so does the call for deeper neurological and psychological research to better understand this fascinating facet of the human mind.
The Origins of Aphantasia: From Aristotle to Modern Science
The term phantasia was introduced by Aristotle around 350 B.C. to describe the mind’s capacity for imagination. Fast forward to 2015, and Professor Adam Zeman of the University of Exeter coined the term aphantasia after studying a patient who had lost his ability to visualize mentally.
Zeman’s research revealed that specific brain regions activate when most people imagine something. However, in people with aphantasia, these areas remain inactive. This led to a deeper investigation of what Zeman called "blind imagination.
How Aphantasia Affects Memory and Daily Life
People with aphantasia often report difficulties recalling visual memories such as vacations or childhood scenes. Their memories are based more on facts and abstract concepts rather than rich imagery.
Interestingly, aphantasia may also affect how individuals process emotions and fear. For example, horror films may not leave a lasting impression because the frightening visuals can’t be replayed mentally. This can reduce susceptibility to post-traumatic visual flashbacks or nightmares.
Testing for Aphantasia
Diagnosing aphantasia isn’t straightforward. There is no definitive brain scan or medical test. One of the most commonly used tools is the Vividness of Visual Imagery Questionnaire (VVIQ), developed in 1973 by psychologist David Marks. Participants rate how vividly they can imagine scenarios, such as a relative’s face or a sunset.
While helpful, the VVIQ relies on self-assessment, making it difficult to measure internal experiences objectively. This underscores the need for more robust scientific research and diagnostic methods.
Aphantasia and Creativity: A Surprising Connection
Contrary to popular belief, many people with aphantasia are highly creative. Ed Catmull, co-founder of Pixar Animation Studios and former president of Walt Disney Animation, is one notable example. Despite being unable to visualize, Catmull contributed to some of the most visually stunning films in history.
Creativity doesn’t necessarily require mental pictures it can thrive through conceptual thinking, logical structuring, and emotional depth. Artists with aphantasia often use external references or draw from emotional intuition rather than visual memory.
Frequently Asked Questions
What does it mean when someone can’t visualize images in their mind?
This condition is known as aphantasia. People with aphantasia are unable to form mental images, even when prompted to visualize something familiar, like a loved one’s face or a favorite place.
Is aphantasia a medical condition?
No, aphantasia is not classified as a disorder or medical problem. It is simply a variation in how people experience mental imagery. Many people with aphantasia live normal, successful lives.
How do people with aphantasia think without mental images?
They often rely on verbal, conceptual, or logical thinking. Instead of “seeing” a sunset in their mind, for example, they may think of the idea of a sunset, using words or abstract associations.
Can people with aphantasia dream?
Yes, they can dream. However, their dreams may be different. Some report dreaming without visual images, experiencing dreams through sounds, emotions, concepts, or words instead.
Is dreaming in words common among people with aphantasia?
It can be. Some people with aphantasia describe their dreams as narrative-driven, where events unfold more like a story or inner monologue, without vivid visual components.
How do people find out they have aphantasia?
Many people discover it by accident through quizzes, conversations, or self-reflection. A common method is trying to visualize a familiar scene and realizing they can’t “see” anything in their mind's eye.
Conclusion
The human mind is wonderfully diverse. Whether you see mental images in full color or think entirely in words, there’s no “right” way to imagine or remember. Aphantasia offers a compelling look at how flexible and adaptive our brains can be.As awareness continues to grow, so does the need for acceptance, research, and deeper conversations around how we each experience the world. And perhaps, understanding conditions like aphantasia will bring us closer to appreciating the full spectrum of human thought.
