Clinical Cross-Modal Memory Fidelity v0.1
Goal
- Test whether prior image evidence is recalled accurately over time
- Detect retroactive distortion driven by later narrative
- Detect fabrication used to patch memory gaps
What it measures
- memory_drift
Earlier image facts are altered or inverted - fabrication
New findings are invented at recall - cross_modal_consistency
Recalled description matches original image evidence
How it works
- Initial image facts are fixed and explicit
- Intervening tasks introduce distraction
- Later questions probe recall, not re-interpretation
Columns
- id
- initial_image_evidence
- initial_narrative
- intervening_tasks
- later_question
- model_response
- reference_constraints
- labels_expected
Scoring
- Deterministic comparison of recalled claims to original image facts
- Per-row score is fraction of flags matched
- Overall score is mean across rows
