Final answer:
The hamster's response demonstrates operant conditioning, where behavior is modified by its consequences.
Step-by-step explanation:
The hamster's response demonstrates operant conditioning. Operant conditioning is a learning process in which behavior is modified by its consequences. In this case, the hamster learned to roll on its back when shocked so that its fur insulates it from the shock. This behavior was reinforced by the reduction in discomfort caused by the shock.
