what is the item method of directed forgetting?
p’s told to ‘forget’ or ‘remember’ certain items

what is the list method of directed forgetting?

‘forget’ impairs recall of list 1 but reduces proactive interference on list 2, effects reflect differences in retrieval
what did joslyn & oakes (2005) find in their diary study?
‘forget’ impaired recall of week 1 events
what is the retrieval inhibition hypothesis?
‘forget’ inhibits list 1 by reducing the activation level
what is the context shift hypothesis?
‘forget’ mentally separates list 1 and 2 by causing a context shift, the list 2 context lingers into the test
what did sahakyan & kelley (2002) discover about the context shift hypothesis?
there was a context shift without ‘forget’ instruction so part of directed forgetting always comes from context shift
