Question 8

(lecture):

SUMMARY

• There are two temporally, topographically and functionally distinct
old/new effects in the electrical record.
- This mid-frontal ERP old/new effect happens between 300-
500 ms and the left-parietal ERP old/new effect happens between 500-
800ms.
- The mid-frontal ERP old/new effect is seen at mid-frontal
scalp locations and the left-parietal ERP old/new effect appears at leftparietal scalp locations.
- The mid-frontal ERP old/new effect seems to be a putative
index of Familiarity and the left-parietal ERP old/new effect seems to be
an index of Recollection.

• This strongly supports the dual-process model, that two processes
contribute to memory judgements.
