“The Giant Black Elephant with white Tusks stood in a field of Green Grass”: Cognitive and brain mechanisms underlying aphantasia

Abstract

Scientists have made significant progress in understanding aphantasia, according to a comprehensive review of recent research. The study analyzed 52 research papers to paint a clearer picture of this unique way of experiencing the world. Key findings show that aphantasia affects approximately 4-9% of the population, though exact numbers vary between studies. While initially thought to just affect visual imagination, research now shows it can impact multiple areas of experience, including memory, emotions, and other senses. The review highlights that aphantasia isn't a disorder or deficit, but rather a different way of processing information. People with aphantasia often develop alternative strategies for tasks that others might approach through visualization. The growing aphantasia community (now including 67,000+ members on Reddit alone) has helped drive research interest and understanding. Researchers are particularly interested in how the brains of people with aphantasia might work differently, especially in areas related to memory and sensory processing. While some cases of aphantasia can occur after brain injury, most people are born with it (congenital aphantasia). The review points to exciting future research directions, including developing better ways to measure and understand aphantasia beyond current questionnaires, and exploring
