Aphantasia and Mental Imagery With Joel Pearson
Mental imagery refers to the experience of creating sensory information in one’s mind without external input from the senses. This can involve visual images, sounds, smells, tastes, movements, or tactile sensations. Aphantasia refers to the inability to create mental images, and recent studies have shown that it can also affect other sensory modalities.
Understanding the variations of imagery differences across sensory domains is important to gain a more comprehensive view of how human imagination works and how it might be related to other cognitive processes, such as memory and creativity.
Joel Pearson is a cognitive scientists and the Founder and Director of the Future Minds Lab at the University of New South Wales in Sydney, Australia. Pearson joins the Aphantasia Network for a live Ask Me Anything member event to answer some of our community’s burning questions about Aphantasia and Mental Imagery.
