Aphantasia: When You Are Blind in Your Mind

This was a technique used by the researchers to help test the image forming inside the brain of the individuals.

The experiment led to the finding that a recent viewing of an image had no correlation with the imagining of the image.

MRI scans in patients show that while recognizing faces show no change, the person finds it hard to ‘imagine’ or conjure imagery, due to a significant reduction in activation patterns across the posterior networks in the brain. Patients, therefore, relied on a different cognitive strategy.

People with Aphantasia are only able to remember things by using words and lists of facts.

Research suggests that this phenomenon has a negative impact on their memory, like being able to remember the details of a particular day, but still not being able to visualize it. This also has an unexpected advantage of them not being disturbed by negative life events getting flashbacked in their minds.

Strangely enough, people with aphantasia can dream normally, being able to see the visuals. It is the intentional ‘imagining’ that is affected and not the dream state.

Dreams are a subconscious mind event, controlled by the brainstem, while visualization requires the conscious mind to process the image.

Not being able to imagine people and places can be bothersome and upsetting for the people with Aphantasia. Many people from all walks of life experience this, and it does not seem to impact their success in life.

This is a normal variation of human experience and is not something that can be treated. However, tools like photography, illustrations, visual aids and design software can be used to fill this gap in the mind.
