... shows for the first time that there is more than one memory.
Memory Systems“this paper ... demonstrated for the first time the presence of operant conditioning in amnesia. After pricking his patient with a pin hidden in his hand, when Claparede again motioned toward her, the patient reflexively withdrew her hand. She argued that there was, perhaps, a pin hidden in his hand, although she did not remember the episode in which this conditioning procedure was acquired.”

Memory Systems
H.M. had incurable epilepsy and was treated with bilateral
temporal lobectomy.This resulted in severe anterograde and mild retrograde amnesia.Based on other patients it was observed that the degree of memory loss correlated with the amount of hippocampus that was removed.

Subjects were called back 1 year later. Comparison between last extinction trial and spontaneous recovery test (ie., Reinstatement index).
The stimulus specificity of fear extinction was tested.Participants saw two squares that were occasionally paired with shock and one that wasn’t.

Summary
Memories are dynamic and integrate retrieval information.
Retrieval information can overwrite existing memories.
Open issues:- Explicit vs implicit memories- Role of reminder/extinction timing and massed extinction.
