retrieval failure Flashcards
retrieval failure
form of forgetting
occurs when we don’t have necessary cues to access memory
memory is available but not accessible unless a suitable cue is provided
cue
trigger of information that allows us to access a memory
cues may be meaningful or may be indirectly linked to being encoded at the time of learning
indirect cues may be external or internal
encoding specificity principle
Tulving - reviewed research into retrieval failure and found consistent pattern
states that a cue has to be present at encoding and present at retrieval
if cues available at encoding and retrieval are different there will be some forgetting
mnemonic techniques
some cues encoded at the time of learning in a meaningful way eg mnemonic techniques - lead to recalling information
context-dependent forgetting
recall depends on external cues eg weather or place
state-dependent forgetting
recall depends on internal cues eg emotion
research procedure - context-dependent forgetting
Godden and Baddeley
deep-sea divers
4 conditions
learn on land - recall on land
learn on land - recall underwater
learn underwater - recall on land
learn underwater - recall underwater
learned a list of words
findings - context-dependent forgetting
two conditions where environment of learning and recall didnt match - accurate recall was 40% lower than matching
external cues available at learning were different from ones at recall led to retrieval failure
research procedure - state-dependent forgetting
Carter and Cassaday - antihistamine to participants
- drowsy
- internal physiological state different from the normal state of being awake and alert
4 conditions
learn on drug - recall on drug
learn on drug - recall when not on drug
learn not on drug - recall on drug
learn not on drug - recall not on drug
findings - state-dependent forgetting
conditions where mismatched - significantly worse recall
when cues absent then more forgetting
real-world application
P - strength can help overcome some forgetting in everyday situation
E - cues may not have very strong effect - Baddeley suggests still worth paying attention too
E - when we have trouble remembering something, worth making effort to recall environment - eye witness testimony
L - shows how research can remind us of strategies we use in the real world to improve our recall
research support
P - strength is impressive range of research support
E - Godden and Baddeley, Carter and Cassaday - two examples of state and context and real world life
E - memory researchers Eyesnck and Keane - retrieval failure is main reason for forgetting from LTM
L - evidence shows retrieval failure occurs in real-world situations as well as in controlled lab conditions
P - however Baddeley - context effects are not very strong in everyday life
E - different contexts have to be very different for effect to be seen
E - learning something in one room and recalling in another unlikely to result in much forgetting and environments not different enough
L - retrieval failure due to lack of contextual cues may not be actually explain much everyday forgetting
recall versus recognition
P - limitation is context effects may depend substantially on type of memory being tested
E - Godden and Baddeley - replicated underwater experiment - used recognition test instead of recall - say whether recognise word
E - when recognition test - no context-dependent effect - performance was same
L - retrieval failure is limited explanation for forgetting - only applies when a person has to recall information rather than recognise it
