VVIQ (Vividness of Visual Imagery Questionnaire)
Definition
The VVIQ is a standardized questionnaire for measuring the vividness of visual imagery. It consists of 16 items where participants rate their ability to visualize on a 5-point scale.
Detailed Explanation
The Vividness of Visual Imagery Questionnaire (VVIQ) is the scientific gold standard for assessing visual imagery ability. It was developed by David Marks in 1973 and has since been the most commonly used instrument in imagery research. The test contains 16 items querying various visualization scenarios: relatives' faces, sunrises, shops, and landscapes. Participants rate the vividness of their mental images on a scale from 1 (no image) to 5 (as vivid as actual seeing). The total score ranges from 16 to 80 points. Scores below 32 indicate aphantasia, while scores above 64 may indicate hyperphantasia. The VVIQ has good psychometric properties with high test-retest reliability and is validated in many languages.

Aphantasia is the inability to voluntarily create mental images. People with aphantasia cannot visualize faces, places, or objects in their mind's eye, although they can recognize and describe them. The term was coined by neurologist Adam Zeman in 2015.

Learn moreMental images are internal visual representations that arise without external stimuli. They enable seeing objects, scenes, or people before the "mind's eye," such as when remembering, dreaming, or planning.
