Aphantasia is a cognitive-neurological difference characterized by a complete or significant inability to intentionally create visual images in one's mind's eye. People with Aphantasia are unable to "see" things in their imagination; when asked to imagine a familiar object, the face of a loved one, or a sunset over the sea, their brain fully understands the concept and facts, but their mental space remains "dark."
The term was redefined and researched intensively in the last decade. It is important to emphasize that Aphantasia is not a disease, a vision impairment, or a defect in intelligence. It is simply a different way for the brain to process, store, and retrieve information - thinking based on concepts, facts, and words, instead of image-based thinking.
The Apple Triangle Test: How Does It Work in Practice?
A simple way to understand Aphantasia is the "apple test." If we ask a neurotypical person to close their eyes and imagine a red apple, they will report varying levels of visualization (from a blurry drawing to a sharp, three-dimensional image).
A person with Aphantasia who closes their eyes will only see black. However, they know exactly what an apple is: they know it's round, it's red, it has a sweet-sour taste, and it grows on a tree. Their brain retrieves the "file" of the apple as textual or conceptual information, without the visual component.
Connection to Comorbidities and Neurodiversity
Modern research shows that Aphantasia is more common among the autistic community and neurodivergent minds compared to the general population. This combination affects several characteristics:
Bottom-up thinking: The autistic brain tends to gather many details to build a concept. For a person with Aphantasia, thinking becomes particularly analytical and systematic. Instead of "seeing" a solution, they build it logically step by step.
Prosopagnosia (Face Blindness): There is a close connection between the two. Since a person with Aphantasia cannot retain a visual image of a face in their mental memory, they must rely on alternative cues (voice, hairstyle, clothes) to identify people, which increases the stress and energy invested in managing social interactions.
Trauma and Memory Processing: Aphantasia has an interesting protective aspect: people with Aphantasia are less likely to experience recurring visual flashbacks of difficult events, as occurs in Complex PTSD, because their brain does not independently generate visual images.
The Cost and Strengths in Daily Life
Similar to a Spiky Skills Profile, Aphantasia also has complex aspects and areas of excellence:
The Valleys (Challenges): Potential difficulty with navigation (inability to "see" a mental map of the route), challenges with autobiographical memory (difficulty visually recalling childhood experiences), or temporary frustration in educational settings that require the use of guided imagery techniques.
The Peaks (Strengths): Exceptional excellence in fields such as science, mathematics, writing, and coding. The inability to rely on images forces the brain to develop highly abstract, fast, and conceptual thinking. Surprisingly, there are also many artists and designers with Aphantasia, who draw and create directly on paper or computer from a deep conceptual understanding of space, without the need for prior internal simulation.
Understanding Aphantasia allows a person to stop feeling "defective" or that something is wrong with them, and to develop learning and working methods adapted to the unique and fascinating wiring of their brain.
