Final answer:
The hippocampus is not involved in implicit learning, which is supported by the fact that individuals with amnesia do not show deficits in implicit learning.
Step-by-step explanation:
The fact that persons experiencing amnesia do not show deficits in implicit learning suggests that the hippocampus is NOT involved in implicit learning. Implicit learning refers to the ability to acquire information and skills without conscious awareness. The hippocampus is mainly associated with explicit memory, which is the conscious, declarative memory of facts and events. However, individuals with amnesia can still learn new procedural memories, such as motor skills, indicating that the cerebellum plays a role in implicit learning.
