The memory performance of patients K.F. and E.E., when compared to the memory performance of people with amnesia, such as patient H.M, demonstrates a double dissociation between two types of memory. Which of the following statements best describes these results?
A)H.M. has a deficit limited to explicit memory, whereas K.F. and E.E. have deficits limited to implicit memory.
B)H.M. has a deficit limited to long-term memory, whereas K.F. and E.E. have deficits limited to short-term memory.
C)H.M. has anterograde amnesia, whereas K.F. and E.E. have retrograde amnesia.
D)H.M. has an injury to the medial temporal lobes, whereas K.F. and E.E. have injuries to the lateral temporal lobes.

H.M. had a deficit in forming new long-term memories (explicit memory) after his surgery, which removed parts of his hippocampus to treat epilepsy, demonstrating a problem with transferring information from short-term to long-term memory. In contrast, patients like K.F. and E.E. typically have deficits in short-term or working memory, often due to damage in different brain areas, showing that these types of memory are supported by different neural structures and processes. This contrast illustrates a double dissociation between long-term and short-term memory systems.
