Olfactory Aphantasia
Olfactory aphantasia is the inability to voluntarily create mental smell experiences - a 'scent-free imagination.' This can occur independently or as part of multisensory aphantasia where multiple forms of mental imagery are affected. Like other forms of aphantasia, olfactory aphantasia can be present from birth (congenital) or develop later in life (acquired). This variation helps researchers understand how the brain processes and remembers smell experiences without mental simulation. On this page, you'll find aphantasia research, personal stories, and community discussions about olfactory aphantasia.
Varieties of aphantasia
Aphantasia is a heterogeneous condition with distinct subtypes involving voluntary imagery, sensory modalities, and spatial versus object details. This diversity suggests that monolithic definitions hinder accurate diagnosis and research.

A decade of aphantasia research – and still going!
A decade of research shows aphantasia is a heterogeneous condition with five dimensions of variation, including sensory reach and spatial imagery. This suggests it is a diverse spectrum of abstract rather than experiential cognitive styles.

Expanding Aphantasia Definition: Researchers Propose New Boundaries
Researchers expand aphantasia definition beyond "inability to visualize." This broader framework impacts how we understand and identify with the condition.
Definition: Aphantasia
Researchers defined aphantasia as the absence of imagery and proposed specific labels for deficits across various sensory modalities. This provides a standardized framework to improve consistency in scientific research and clinical diagnosis.

Proposal for a consistent definition of aphantasia and hyperphantasia: A response to Lambert and Sibley (2022) and Simner and Dance (2022)
Researchers propose defining aphantasia as the absence of voluntary sensory imagery across any modality. This unified terminology avoids confusing new jargon while acknowledging that imagery extremes often affect multiple senses.

3 Things I Learned From Having Multisensory Aphantasia That Changed My Understanding Of The World
My journey understanding the cognitive profiles of aphantasia and hyperphantasia started when I learned at age 30 that most of you have a superpower I don’t.
