Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Sensory Perception

Background:

  • Metacognition in olfaction is understudied.
  • Previous findings on odor memory judgments require further investigation.
  • Understanding subjective knowledge of odor identification is crucial.

Purpose of the Study:

  • To investigate metacognitive judgments of odor identity.
  • To examine the relationship between feeling of knowing and odor recognition.
  • To explore the 'tip of the nose' phenomenon in olfactory recall.

Main Methods:

  • Two experiments were conducted.
  • Participants made metamemory judgments about odor identity.
  • Judgments included feeling of knowing and retrospective confidence.

Related Experiment Videos

Main Results:

  • Feeling of knowing predicted odor recognition, contrary to prior research.
  • Participants were confident but overconfident in odor identification.
  • A 'tip of the nose' sensation predicted recall but lacked partial name activation.

Conclusions:

  • Olfactory metamemory is linked to actual knowledge.
  • Metamemory for odors aligns with findings in other sensory modalities.
  • The 'tip of the nose' phenomenon differs from the 'tip of the tongue' state.
