Aphantasia

Aphantasia refers to the absence of internal sense perceptions when remembering or imagining. It means knowing that you just ate a delicious chocolate cake, but not being able to re-experience its taste in your mind. People with visual aphantasia don't generate an image in their mind’s eye when hearing words like “apple” or “tree” or “dog.” The brain’s image-processing and memory systems are involved in a range of conscious and unconscious experiences. Aphantasia is associated with a range of consequences, including impaired autobiographical memory and, potentially, less emotional awareness and empathy. It's an under-recognized aspect of neurodiversity. Steve explores this experience and reflects on the uncanny fact that other peoples’ consciousnesses can work differently than our own, in more or less subtle ways with far-reaching effects.
