Document Summary

Amnesia: hm: bilateral removal of the hippocampal region caused sever memory loss, profound anterograde amnesia from immediately after surgery, retrograde amnesia, last 2 years before surgery, hippocampus: involved in learning, memory and emotion, can acquire new procedural tasks. Impaired in tests of explicit but not implicit memory. Intact stm, language, knowledge of past world events, skill learning. Evidence that it relies on different memory system: dissociations: variable affects performance on one memory task but has no effect/ different effect on another task, dissociations between implicit and explicit memory tasks: Amnesia: affects explicit but not implicit memory performance. Depth of encoding affects explicit but not implicit memory task: double associations: depth of processing at encoding. Implicit memory better after shallow processing: double dissociating is consistent with anatomically separate implicit and explicit memory systems. Implicit and explicit memory task: transfer-appropriate processing: Memory depends on the match between encoding and retrieval processes: perceptually driven vs. conceptually driven.
