People with aphantasia cannot voluntarily create mental images in their minds. New research shows training programs can help some of these individuals develop this ability, forcing neuroscientists to reconsider how imagination works.
Aphantasia affects roughly 2-3% of the population. Those with the condition report no visual experience when asked to picture a sunset or a friend's face. Scientists previously assumed this reflected a permanent neural difference, similar to color blindness.
Recent training studies contradict that assumption. Participants with aphantasia who completed structured visualization exercises developed measurable improvements in mental imagery. Some reported seeing their first mental images after years of inability.
The findings suggest the brain retains plasticity in this domain. Visualization may depend partly on learned skills rather than fixed brain architecture. This reshapes our understanding of mental imagery as something trainable rather than innate.
Researchers now plan larger trials to determine which training methods work best and whether benefits persist. They want to identify whether aphantasia stems from multiple causes. Some people may have neurological barriers while others lack developed visual thinking habits.
These discoveries could eventually lead to targeted interventions for people with aphantasia who want to develop mental imagery. The research also hints that human perception remains more flexible than previously thought.
