Which memory profile fits KF's case?

Which memory profile fits KF's case?

• A. Impairment of short-term memory with intact long-term memory
• B. Long-term memory impaired with intact short-term memory
• C. Both memory systems impaired
• D. Memory preserved in both

Answer: (A)

Dissociation between short-term (working) memory and long-term memory is illustrated by KF's case. KF had a marked difficulty with auditory‑verbal short-term memory—his digit span was severely reduced and he struggled to hold spoken information briefly. Yet his ability to form and retrieve long-term memories for events and facts remained largely intact. This pattern shows that short-term memory can be impaired while long-term memory stays preserved, implying separate underlying systems. That makes this memory profile the one with impairment of short-term memory and intact long-term memory.
