Document Summary
Transfer from short-term memory [stm] to long-term memory [ltm] Remember info on screen" [example in textbook] H m - knocked down, suffered a head injury in childhood . Surgery: took out the hippocampus - immediately realized hm was not able to store information in his ltm. Had motor memory; but cannot recall single specific events. Surgery to relieve epilepsy caused catastrophic amnesia. Doesn"t remember his friend - reintroductions every time they met. Mirror tracing - with practice, fewer and fewer mistakes. Had to explain how to do the task every time. Motor memories are spared in a lot of amnesics. Because their motor memory is still intact, amnesics can sometimes phone home. Hm"s memory of floor plan of home he lived in from 1966-1973 [still remembered his home"s floor plan] Memory is not evenly distributed throughout the brain. Patient kf - impaired stm but intact ltm. Hm had retrograde amnesia and anterograde amnesia.
