-
Therapists sometimes use techniques similar to experimental extinction to modify unwanted habits.
-
The study on experimental extinction yielded significant results.
-
Researchers observed experimental extinctions in various subjects.
-
The study demonstrated that after the reward was removed, experimental extinction caused the conditioned response to weaken significantly.
-
In the experiment, the rats experienced experimental extinction when they stopped receiving food, leading to a decrease in their learned behavior.
-
The concept of experimental extinction is essential in understanding how behaviors can diminish over time without reinforcement.

Morphology
The phrase is straightforwardly compositional: 'experimental' (relating to experiments) simply modifies 'extinction' (the reduction of a learned response), so it refers to extinction as observed or produced in an experimental context. This adjective+noun combination follows a predictable pattern and would be understandable to a learner who already knows the meanings of both constituents.
Etymology
Experimental extinction comes from simple lab tests of learning: when a person or animal is trained but the reward is later taken away, the learned action slowly 'fades'. So extinction means the learned action gets weaker or 'stops', and experimental shows this was seen in experiments.
