A common finding in event-related potential (ERP) studies of recognition memory is that recognised items elicit greater positivity at parietal electrode sites than new items (the 'left parietal old/new effect'). Parietal positivity (the P300 or P3b) is also elicited in detection tasks with no memory demands by items of low probability of occurrence and high 'target value'. It has been argued that correctly recognised items are typically associated with lower probability and higher target value… CONTINUE READING
