Imagine this: you close your eyes and picture a bright blue sky. Suddenly, it becomes even brighter, and a rainbow appears. As you turn your head, you see another rainbow, creating a vivid double rainbow. How clear is this image in your mind? Can you see each color distinctly? Can you imagine a bird flying across this scene?
For some people, this exercise is impossible. They have a condition known as Aphantasia, which means they have little or no ability to create mental images. It’s often described as having a “blind mind’s eye.”
Meet Andy, who believes he has Aphantasia. When asked to imagine his breakfast table, Andy’s brain doesn’t produce a visual image. Instead, he thinks of a list of words or concepts related to the table. If you asked him to describe his dining room table without prompting him to visualize it, he would rely on descriptive words rather than visual metaphors.
Aphantasia has been known since the 1880s when Sir Francis Galton conducted studies asking people to visualize their breakfast tables. While some, like Charles Darwin, could see images as clearly as photographs, others couldn’t visualize anything at all.
In the early 2000s, neurologists at the University of Exeter studied a patient known as MX, who lost his ability to visualize after surgery. When MX was shown a picture of then Prime Minister Tony Blair in an fMRI machine, his brain showed normal visual activity. However, when asked to imagine Blair’s face, his brain activated areas related to semantic retrieval rather than visual imagery. MX was trying to imagine using words instead of pictures.
When this research was published in 2010, it sparked interest, leading to a flood of emails from people who experienced similar challenges. In 2015, researchers officially named this condition “Aphantasia.” They found that most people with Aphantasia couldn’t voluntarily create mental images, though they might experience brief visual flashes, such as in dreams. Many discovered their condition in their teens or twenties and reported difficulties in recalling past events.
For some, like Andy, learning about Aphantasia was a revelation. It was like discovering they were color blind, realizing that what they thought was a language quirk was actually a unique way their brain functions.
The lead researcher noted the widespread interest and relative obscurity of Aphantasia. While the reasons for such varied human experiences remain unclear, scientists are using brain imaging to explore this fascinating condition further.
The story of Aphantasia highlights how individual experiences can contribute to a broader understanding of brain function. As research continues, we may soon understand more about why some people can vividly visualize a double rainbow while others cannot.
Engage in a workshop where you explore your own visual imagery capabilities. Close your eyes and attempt to visualize various scenes, then discuss your experiences with peers. This will help you understand the spectrum of visualization abilities and where you might fall on it.
Read and analyze case studies of individuals with Aphantasia, such as Patient MX. Discuss in groups how their experiences differ from those with typical visualization abilities and consider the implications for learning and memory.
Write a short story or descriptive passage without using visual imagery. Focus on other senses and abstract concepts to convey your narrative. This will challenge you to think beyond visual descriptions and appreciate different cognitive styles.
Participate in a seminar on brain imaging techniques used to study Aphantasia. Learn how fMRI and other technologies help researchers understand brain function related to visualization and discuss potential future research directions.
Reflect on your own experiences with visualization and consider how they affect your daily life and learning. Share your reflections in a group discussion, and explore how understanding Aphantasia can enhance empathy and communication with others.
Sure! Here’s a sanitized version of the transcript:

Okay, there’s something I want you to visualize. If it helps, perhaps close your eyes. In your mind, I want you to imagine the sky. It’s really blue, and suddenly it becomes brighter. Then, a rainbow appears. You turn your head, and another rainbow appears. It’s a double rainbow, so vivid and intense. Now, how clear is this mental image? Can you see each color in the rainbow? Can you picture a bird flying in front of it?
When some people are asked to picture something with their mind’s eye, they just can’t.
Hey Andy, it’s Vanessa! How are you? I’m quite well, yourself? I’m well.
Now, Andy believes he has Aphantasia—a condition where you have little or no mental imagery. It’s been referred to as “blind imagination” or having a blind mind’s eye. I asked Andy to imagine his breakfast table, and his brain uses different strategies to address these visual challenges. It’s more akin to a word cloud, like a long list of adjectives that describe the table. If you were to take me out of my kitchen and ask me to describe my dining room table, I could tell you things about it, but if I wasn’t told to imagine it, I wouldn’t use visual metaphors. When I think of a coffee table, I more imagine concepts about coffee tables.
I learned about Aphantasia a few weeks ago when Andy commented on my last video, saying, “I don’t have any visual memory or imagination.” People commenting on articles was how this condition began to be studied.
We’ve known that some people have a “blind imagination” since the 1880s when Sir Francis Galton asked people to visualize things about their breakfast table. One of the subjects, Charles Darwin, said it was “as distinct as if I had photos before me.” But a few people couldn’t visualize the table at all. Fast forward to the early 2000s when neurologists at the University of Exeter encountered patient MX—a Scottish man who lost his ability to visualize things after surgery.
When MX was in an fMRI machine, researchers showed him a picture of then Prime Minister Tony Blair and asked questions like, “Does he have large ears?” As expected, they saw normal activity in his visual areas. Next, they asked him to imagine Blair’s face, expecting to see similar brain activity. But instead, many brain areas were active, including those used for semantic retrieval. MX was trying to imagine a face, but in a non-visual way, using words instead of images.
When that research was published in 2010, Carl Zimmer wrote an article for Discover Magazine, and emails started rolling in from people who experienced the same thing, some since birth. The blind imagination of this group of emailers became the focus of a new paper published by the same researchers in 2015, who officially named this “Aphantasia.” They found that the majority of the group couldn’t conjure up a mental image at will, but they still had ‘flashes,’ perhaps in dreams. Most said they had some trouble remembering past events and discovered their Aphantasia in their teens or twenties.
I didn’t realize until recently that to visualize, in terms of the mind’s eye, I thought those were euphemisms, maybe a quirk of the English language. It felt like not realizing I was color blind. From here, Carl Zimmer wrote about the article again, SciShow posted a video on it, and the researchers received close to a thousand emails from people who had just heard of Aphantasia and believed they had it—similar to Andy.
As the lead researcher put it, “attesting to the popular interest and relative obscurity of this fascinating variation of human experience.” But why is the human experience so varied? We don’t know. But scientists are digging deeper into Aphantasia using brain imaging.
The story of Aphantasia shows us how we can all contribute to a better understanding of how the brain works and how you work. Soon, we’ll know more about how some of us can visualize a double rainbow in the first place.
