Frequently Asked Questions
Here’s a quick rundown of some of the frequently asked questions we get asked about aphantasia.
People can take tests like binocular rivalry and other experiments. People who are claiming to have vivid imagery have very different responses to these tests than aphantasics. Although this doesn’t let us know positively that they’re vividly seeing an image, it all points to the fact that something is truly different between people who claim to see vividly and those who don’t. We can also see activation in the visual cortex, the area in the brain that processes images from the eyes, which further suggests actual visualization.

It can, but not always. Some people with visual aphantasia experience imagery in other senses. ~50% of aphantasics will report aphantasia in all senses. What's your inner experience like? Discover your unique Imagery Profile.
Many people have aphantasia since birth, “Congenital Aphantasia.” It is occasionally a symptom of other disorders: for example, aphantasia can result from a stroke, head injury or an episode of depression, however these occurrences appear to be considerably less common. So if someone who has previously had imagery loses it suddenly, it’s reasonable to ask and attempt to learn why.
Aphantasia isn't a disability, disorder, nor defect. It's a variation in human experience, and an intriguing one. Aphantasia reminds us that there are major invisible differences between people's inner lives.
There are objective ways to measure aphantasia. The most reliable that we know of so far is using a method called Binocular Rivalry, paired with a technique called perceptual priming. Binocular Rivalry is a phenomenon of visual perception in which perception alternates between different images presented to each eye, and vividness of visual imagery has been shown to affect these outcomes.

The opposite of aphantasia is known as hyperphantasia. This term which denotes the other extreme of the imagination spectrum is defined as the ability to voluntarily produce hyper-vivid mental imagery. For someone with visual hyperphantasia, visualizing can look as vivid as seeing with their eyes.

Aphantasia is not a barrier to leading a rich, creative and fulfilling life. Ed Catmull, co-founder of Pixar with Steve Jobs and former president of Walt Disney Animation Studios. Craig Venter, biologist who first sequenced the Human Genome. Blake Ross, creator of Mozilla Firefox. Glen Keane, Disney Animator and Creator of The Little Mermaid. Penn Jillette of Penn and Teller. All have aphantasia.
