What does retrieval failure suggest?
information is not recieved due to absenrbof cues at the time of recall
what are the two types of forgetting
context depending forgetting & state depending forgetting
define context dependent forgetting
At recall we lack external environmental cues that were present when learning
define state dependent forgetting
At recall we lack internal cues that were presenent when learning this could be psychological or physiological
What are 3 case studies that support the idea of retreival failure
Tulving & Pstoka , Godden & Baddley & Lowe
context depending - divers
Outline Godden & Baddley experiment
supports
Divers recalled a list of words either underwater or on land
they found that recalling was better when the conditiond were matched (you recalled in the area you learned rhe words).
learning and recalling underwater or on land
this demonstrated the idea of context dependent forgetting
state dependent cues - alcohol
Outline Lowe experiment
Participant memorised map drunk or sober and were able to reca,ll information in the same state it was learnt in.
Found that recall was better when they were in the same state as learning. Mismatch will hinder memory recall
Limitations of Godden & Baddley
lacks ecological validity
Baddley argued that its difficult to find conditions that are polar as water and land
suggests that this study may be best suited to explaining where cases of forgetting are uncommenly distinct
doesn ‘t provide accurate depiction of forgetting in day to day life
advanatages of the retreival failure being a resons that we forget info from the LTM
lab experiment so it was controlled reducing effects of bias and extranous variables
this increases the validity of retreival being an ecplanation of forgetting
