How clearly you can imagine smells such as coffee, rain, perfume, or smoke.
You might also hear it called smell aphantasia, Do I have smell aphantasia?, Can I imagine smell?. This guide explains what it means, signs to look for, and how to find out where you fall on the spectrum.
Olfactory imagination is your ability to mentally evoke smells without a physical odor present. Tools like the Vividness of Olfactory Imagery Questionnaire (VOIQ) distinguish 'good' (vivid) from 'weak' olfactory imagers using familiarity, emotional processing, and memory—with substantial individual variation even when population-level prevalence data is limited.
Smell imagery is generally weaker and more variable than visual imagery in the general population; odor imagery is often described as a challenging cognitive function. Many people underestimate this dimension because smell gets less explicit attention in school and work.
Assessments like the VOIQ use familiar odor scenarios and vividness ratings; they reliably separate vivid from weak olfactory imagers. Research shows that odors difficult to name are also difficult to imagine—so learning scent names can improve how well you perform on imagery tasks.
The Imagination Index assessment measures this dimension along with the other five senses in about 12 minutes. You get a clear profile of where you fall—free to start, no signup required.
Many people are mixed across senses. Comparing dimensions often helps more than interpreting one in isolation.
Yes, in the general population smell imagery tends to be less vivid and more variable than visual; behavioral and physiological studies support that. There is still substantial individual variation—some people have strong olfactory imagery.
Yes. Repeatedly imagining odors improves detection and identification, with effects comparable to actual perception training. In one case, accuracy rose from 81% to 96% over 16 days with about 10 minutes daily practice. The piriform cortex (olfactory cortex) activates similarly for real and imagined smell; the skill strengthens with use. Training effects can be odorant-specific, so gains may not transfer to all scents.
Quick self-check: learn names of common scents (rose, vanilla, coffee), then try to mentally recreate each without smelling. Or use a valence/arousal frame—imagine pleasant high-arousal (citrus), pleasant low (lavender), unpleasant high (ammonia), unpleasant low (stale)—and notice what memories or sensations arise. Pairing scents with personal memories and journaling what you notice builds capacity over time.
