Calibrate construct and measurement validity: Extension Ratios, Area, and Salience
RFR-F5EB32EB — Calibrate construct and measurement validity: Extension Ratios, Area, and Salience
Research opportunity
Calibrate construct and measurement validity for the claims or recommendations in “Extension Ratios, Area, and Salience.”
Background
The originating artifact is accepted by the repository publishing inventory with status “computational-pilot-complete-human-study-pending.” Its Work completed section provides the immediate evidence boundary.
Evidence trace
- Origin document: content/projects/itten-color-contrasts/experiment-report/EX-ITTEN-001-extension-area-salience.md
- Section:
Work completed - Specific assumption challenged: The source's treatment in “Work completed” is sufficiently supported for its intended scope.
- Supporting evidence excerpt: “A deterministic full-factorial pipeline test crossed four area fractions, four luminance differences, three chroma differences, three positions, and two semantic priority levels: 288 modeled conditions. The proxy was intentionally explicit: area^0.62 × hypot(3.2ΔL, 1.7ΔC) × center-bias × semantic-priority . This tests…”
- Reason this opportunity exists: Whether the document's operational measures isolate the intended construct rather than a correlated proxy or decision strategy.
Unknowns
- Whether the document's operational measures isolate the intended construct rather than a correlated proxy or decision strategy.
Dependencies
- None; this is foundational work.
Suggested REP and methodology
- Suggested REP:
REP-EX-ITTEN-001-MEASUREMENT - Methodology: Define the construct, compare convergent and discriminant measures, estimate reliability, test measurement invariance, and publish calibration data.
- Expected outputs: Construct definition, measurement protocol, reliability study, calibration dataset, and validity report.
- Success criteria: Measures meet declared reliability and validity thresholds across the principal populations and contexts.
- Recommended agent:
measurement-research-agent - Estimated effort: Medium
- Expected knowledge gained: Whether the document's operational measures isolate the intended construct rather than a correlated proxy or decision strategy.
