Imagination Index vs Psi-Q
Psi-Q is a validated multisensory imagery questionnaire used in academic research. Imagination Index also measures multiple senses but delivers a free online Imagery Profile with population percentiles. Choose Psi-Q for published study protocols; choose Imagination Index for personal or team use without a lab setup.

Psi-Q (Plymouth Sensory Imagery Questionnaire) helped establish that imagination is not visual-only. Imagination Index shares that philosophy but targets a different use case: immediate, actionable profiles online.

What Psi-Q measures
Developed at Plymouth University, Psi-Q assesses vividness across sensory modalities in one instrument. It appears in chemosensory, memory, and clinical imagery research where multisensory measurement matters.
- Validated multisensory factor structure in published work
- Typically administered in research settings—not a consumer product
- Versions vary in which modalities are emphasized
How Imagination Index differs in practice
Same core idea—measure more than vision—but Imagination Index optimizes for discovery: free access, immediate profile, percentile context, optional AI-generated narrative, and share/compare features for teams.

Which should researchers cite?
For academic protocols requiring a specific validated instrument, use Psi-Q or VVIQ as your methods section specifies. Imagination Index is designed for individual and applied use rather than replacing established lab instruments.
