PSIQ (Plymouth Sensory Imagery Questionnaire)

The Plymouth Sensory Imagery Questionnaire (PSIQ) extends the assessment of imagery ability beyond the visual domain. It was developed to understand whether people with visual aphantasia also have limitations in other sensory modalities. The PSIQ contains 35 items querying imaginations in five areas: seeing (e.g., a friend's face), hearing (e.g., voice), smelling (e.g., freshly baked bread), tasting (e.g., lemon), and feeling (e.g., sand between toes). Research results show that aphantasia is often limited to the visual domain, but some affected individuals are also limited in other modalities. The PSIQ helps capture a person's complete sensory profile and identify subtypes of aphantasia.
