Use when
- A protocol needs the exact measured value defined before data collection.
- Multiple methods produce similar-looking outputs but different interpretations.
- A methods section needs consistent units, epoch, and exclusion language.
Science Concepts
Concept
Behavioral endpoints
A behavioral endpoint is the measured output of a method, not the biological interpretation by itself.
Decision summary
Use endpoint language when the page needs to pin down the observable value: latency, distance, zone time, freezing percentage, response threshold, or score. Interpretation comes later and must stay tied to the method, species, and controls.
| Measured value | The raw or derived output recorded from behavior, such as latency or threshold. |
|---|---|
| Unit | Seconds, centimeters, percentage, score, force, count, or event rate. |
| Context | Assay, apparatus, species, trial epoch, and response definition. |
| Interpretation boundary | The endpoint supports a claim only inside the validated method context. |
Do not use when
- The page is really about a disease model, not the measured output.
- A construct such as anxiety or pain is being inferred without naming the method and endpoint.
Caveats
- Endpoint names often sound biological, but the endpoint is still a measurement.
- Species, apparatus geometry, software detection, and exclusion rules can change the same endpoint.
- Derived scores should keep raw fields available for audit.
Reporting checklist
- Name the endpoint and unit.
- Define the event boundary or scoring rule.
- State trial duration or epoch.
- Report exclusions and missing-data handling.
- Link the endpoint to the method and apparatus or product surface used.
