Explanations of Forgetting: Retrieval Failure Flashcards
why may people forget information(cues)?
there are insufficient cues
what is the importance of cues in memory?
- when information is initially placed in memory, associated cues are stored at the same time
- if the cues are not available at the time of recall we appear to have forgotten the information
what is retrieval failure?
not being able to access memories that are there
what is the encoding specificity principle?
- a cue has to be both present at encoding and present at retrieval
- if the cues at encoding and retrieval are different we can forget
what cues are meaningful?
some cues are encoded at the time of learning in a meaningful way, e.g. mnemonic techniques
what are examples of non-meaningful cues?
- context-dependent forgetting
- state-dependent forgetting
what is context-dependent forgetting?
recall depends on external cue
what is state-dependent forgetting?
recall depends on internal cue
who are the researchers involved in context-dependent forgetting?
Godden and Baddeley
what is Godden and Baddeley do?
- studied deep-sea divers who work underwater
- divers learned a list of words either underwater/on land and had to recall underwater/on land
- 4 conditions
what was the findings of Godden and Baddeley?
- accurate recall was 40% lower in non-matching conditions
- external cues available at learning were different from ones available at recall
who were the researchers involved in state-dependent forgetting?
Carter and Cassaday
what did Carter and Cassaday do?
- gave antihistamines drugs to their ppts
- antihistamines gave a mild sedative effect = ppts drowsy
- this created an internal physiological state different from normal state of being awake and alert
- ppts had to learn list of words and passages of prose and recall information
- 4 conditions
what were the findings of Carter and Cassaday?
- when there was a mismatch between internal state at learning and recall, performance was significantly worse
- cues were absent = forget
what are the evaluations of retrieval failure?
+ retreival cues can help overcome some forgetting in everyday situations
+ research supports the retrieval failure explanation
- context effects may depend substantially on the type of memory being tested
