Final answer:
The patient H.M. remained fairly normal in his ability to learn working memories despite his severe amnesia.
Step-by-step explanation:
The patient H.M., who suffered from severe amnesia, was still fairly normal in his ability to learn working memories. Working memory is a temporary storage system that helps us hold and manipulate information in our mind in order to complete tasks. While H.M. had difficulty forming new memories, such as episodic and semantic memories, he was still able to use his working memory to learn and remember new information for a short period of time.
For example, H.M. could learn new skills, such as solving puzzles, even though he couldn't remember learning them. Each day, his speed at solving the same puzzle would improve because of his ability to use his working memory to learn and retain the necessary information.
