Probe trial
A test session where the learned target is removed or altered so retention can be measured without simple reinforcement.

A broader home for the vocabulary researchers use when choosing apparatus, designing paradigms, scoring endpoints, and reading behavioral protocols.
A glossary is useful, but too small. Concepts can hold plain definitions, related apparatus, measured endpoints, protocol context, and links into the rest of the science library.
Parts, layouts, zones, chambers, cues, sensors, platforms, grids, and arena geometry.
Task names and phases across anxiety, memory, motor, pain, reward, and social behavior.
Measured outputs, derived scores, thresholds, indices, and quality-control flags.
Species, strain, age, sex, housing, water, lighting, and acclimation constraints.
Counterbalancing, randomization, blinding, cohort structure, and exclusion rules.
Disease-area vocabulary that connects phenotypes to apparatus and behavioral batteries.
These are examples of the unit this section should scale around: one concept, one plain definition, one research context, then useful links outward.
A test session where the learned target is removed or altered so retention can be measured without simple reinforcement.
Wall-hugging behavior, often used as an anxiety or exploration readout in open field and aquatic assays.
The time from trial start or stimulus onset to a defined behavioral event, such as fall, escape, or response.
A pre-test exposure period that reduces novelty responses before the measured task begins.
The duration or percentage of time spent inside a defined area of an apparatus or video frame.
A design practice that distributes side, order, cue, or condition assignments across groups to reduce bias.
