Understanding Aphantasia
Science-based information about the mental imagery spectrum – from aphantasia to hyperphantasia.
What is Aphantasia?
Aphantasia is the inability to voluntarily create mental images. When you imagine a red apple – can you see it in your mind's eye? People with aphantasia see nothing. They know what an apple looks like, but cannot visualize it. This affects about 1% of the population.
At a Glance
- About 0.9-1.2% have strict aphantasia (Wright et al. 2024)
- Another 3% have hypophantasia (reduced imagery)
- Not a disease – a neurological variation
- Term coined in 2015 by Adam Zeman
