Final answer:
The movie 'Fifty First Dates' indeed features a form of amnesia similar to anterograde amnesia, where new episodic or semantic memories cannot be formed, but new procedural memories can, as exampled by patient H.M.
Step-by-step explanation:
The movie 'Fifty First Dates' features a character with a type of amnesia where they are unable to form new episodic or semantic memories, which aligns with anterograde amnesia. A well-known case that illustrates this condition is that of patient H.M., who, after brain surgery, could not remember reading the same magazine or people he had met post-surgery. Despite not recalling having seen a puzzle before, H.M.'s ability to solve it improved over time due to relearning, indicating that while he struggled with new episodic and semantic memories, he was still able to form new procedural memories.
