PS260 Lecture Notes - Lecture 9: Anterograde Amnesia, Implicit Memory, Explicit Memory
Document Summary
The distinction between explicit and implicit memory is also supported by evidence from cases of brain damage. Amnesia is a disruption of memory due to brain damage. Retrograde amnesia is an inability to remember events that occurred before the event that triggered the memory disruption. Anterograde amnesia is an inability to remember experiences after the event that triggered the memory disruption. More likely to be brain damage than trauma. The person known as h. m. was one of the most studied patients with amnesia. As a last resort in treating h. m. "s case of epilepsy, portions of the brain that caused the seizures were surgically removed. Afterward, h. m. had a severe anterograde amnesia and was unable to recall anything that took place after his surgery, as if nothing could get into long-term memory. A similar form of anterograde amnesia is observed in people with korsakoff"s.
