Use when
- The environment, zones, and sampling opportunities are standardized.
- Distance, entries, and dwell time can be interpreted together.
- Lighting, odor, prior handling, and arena history are controlled.

Research paradigm
Exploratory behavior paradigms
Exploratory behavior paradigms measure how subjects sample an environment, requiring careful separation of exploration, locomotion, and avoidance.
Decision summary
Use exploratory behavior paradigms when the question is about environmental sampling, novelty response, or zone allocation. Interpret zone time and distance together so changes in movement are not mistaken for changes in exploration.
| Common endpoints | Distance traveled, center time, zone entries, dwell time, and velocity. |
|---|---|
| Core contrast | Sampling pattern versus overall movement level. |
| Confound watch | Lighting, handling, odors, wall-following, and tracking loss. |
| Analysis need | Zone definitions and tracking quality checks before interpretation. |
Do not use when
- Motor impairment, sedation, or tracking failure dominates the behavior.
- The zone definitions or arena conditions changed across groups or sessions.
Caveats
- Reduced center time can reflect low locomotion, avoidance, thigmotaxis, or arena unfamiliarity.
- High distance traveled does not automatically mean greater exploration.
- Lighting and prior handling can change exploratory patterns substantially.
Reporting checklist
- Report arena dimensions and zone definitions.
- Report illumination level and testing order.
- Report distance, dwell time, and entries together when available.
- State habituation and cleaning procedures.
- Report tracking exclusions and missing-frame handling.
