Meaning & Perception Lab
Connect words to definitions, document image evidence, and explore sound patterns. Drafts stay in browser memory; export before leaving. Raw images are never uploaded.
1. Words → definitions → Matrix
A starter vocabulary maps exact words and phrases in your text. It does not infer every word’s meaning; context and alternate senses need review.
Add a contextual definition
2. Image evidence review
Automated checks measure file identity and preview pixel statistics. Interpretation is a structured human review. There is no universal scientific “realness score.”
No image selected.
Network0’s rubric is informed by NIST content-transparency guidance; it is not a NIST-certified detector. Appearance cannot authenticate an image.
3. Golden-ratio sound experiment
φ = (1 + √5)/2 ≈ 1.618034. Two sine tones use f₂ = φf₁. This is a sound-design choice with no established focus benefit here. It is not a binaural-beat or brainwave treatment.
Start at low device volume; stop if uncomfortable. This tool cannot measure headphone or speaker sound pressure.
Sound off. Nothing plays automatically.
For a personal comparison, use the same task with silence, 3:2 and φ in randomized order over repeated sessions. Self-reported preference is not proof of cognitive improvement.
