Explanations for forgetting: Retrieval failure Flashcards
What is Retrieval failure?
- A form of forgetting which occurs when we don’t have the necessary cues to access memory
- Memory is available but not accessible until cue is provided
What are cues?
- A ‘trigger’ of information that allows us to access a memory.
Include indirect external or internal cues
What is Tulving’s encoding specificity principle?
- This states that a cue has to be both present at encoding and present at retrieval for it to be helpful
Give an example of cues encoded in a meaningful way
mnemonic techniques
Give two examples of non meaningful cues
- context-dependent forgetting- recall depends on external cue (weather or place)
- State dependent forgetting- recall depends on internal cue (being upset etc)
Who did research on context-dependent forgetting?
Godden & Baddeley
Outline Godden & Baddeley’s procedure
- studied deep sea divers who work underwater to see if training on land helped or hindered their work underwater
- 4 conditions:
-learn on land- recall on land
-learn on land- recall underwater
-learn underwater- recall underwater
-learn underwater- recall on land
What were Godden & Baddeley’s findings?
- In two of these conditions the environmental contexts of learning & recall matched
- accurate recall was 40% lower in the non-matching conditions which led to retrieval failure
- this was due to difference in external cue at learning & recall
Who did research on state-dependent forgetting?
Carter & Cassaday
Outline Carter & Cassaday’s procedure
- gave antihistamine drugs to their participants
- created an internal psychological state different from the ‘normal’ state of being awake & 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
What were Carter & Cassaday’s findings?
- conditions were there was a mismatch between internal state at learning and recall performance on memory test= significantly worse
What is a strength of retrieval cues in terms of real- world application?
- RC >help to overcome some forgetting in everyday situations
- Baddeley suggested they’re worth paying attention to
- e.g. all had experience of being in one room & thinking I need to get something from another room
- go to other room and forget what you wanted but the moment you go back to original room we remember
- context dependent forgetting =credible
- reminds us of strategies used in real life to improve recall
What is a strength of retrieval failure explanation in terms of research to support?
- impressive range of research that supports
- studies by Godden & Baddeley & Carter & Cassaday show that a lack of relevant cues at recall can lead to context & state dependent forgetting
- Memory researchers argue that retrieval failure is main reason for forgetting in the LTM
- shows retrieval failure occurs in real world situations
What is a counter point to research supporting retrieval failure as an explanation?
- Baddeley argues that context effects are actually not very strong especially in everyday life
- different contexts have to be very different before an effect is seen
- e.g. learning something in one room & recalling it in another is unlikely to result in much forgetting > environments generally not different enough
- retrieval failure may not explain much everyday forgetting
What is a limitation of retrieval failure?
- context effects may depend on the type of memory being tested
- Godden & Baddeley replicated their underwater experiment but used a recognition test instead of recall
- p’s had to say whether they recognised a word read to them from a list
- no context-dependent forgetting=performance same
- limited explanation retrieval failure only applies when a person has to recall not recognise
