explanation for forgetting: retrieval failure. Flashcards
(20 cards)
define retrieval failure
form of forgetting. Occurs when we don’t have the necessary cues to access memory. Memory is available but not accessible unless a suitable cue is provided.
what is retrieval failure due to
absence of cues.
define absence of cues
when info is initially placed in memory, associated cues are stored at the same time
what happened when the cues are not available at the time of retrieval
it may of appeared that information has been forgotten.
define cues.
trigger of information that allows us to access memory. cues may be meaningful or may be indirectly linked by being encoded at the time of learning
Who studied retrieval failure
Tulving (1983)
what did Tulving do.
reviewed research into retrieval failure and discovered a consistent pattern to the findings.
what was tulvings principle called
Encoding specificity principle (ESP)
what dose the Encoding specificity principle state.
cues help retrieval if the same ones are present both
(1) at encoding (when we learn the material)
(2) at retrieval (when we are recalling it).
what is a example of a meaningful cue.
the cue ‘STM’ may lead you to recall lots of material about short-term memory. Such cues are used in many mnemonic techniques.
what is an example of non-meaningful cue.
(1) context-dependent forgetting – recall depends on an external cue
(e.g. weather or place)
(2) state-dependent forgetting – recall depends on an internal cue
(e.g. feeling upset, being drunk)
who studied research into context-dependent forgetting.
Godden and Baddeley (1975)
what was Godden and Baddeleys procedure
Deep-sea divers learned word lists and were later asked to recall them.
what where the four conditions of Goddens and Baddeleys study
1: learn on land and recall on land
2: learn on land and recall underwater
3: learn underwater and recall on land
4: learn underwater and recall underwater
what where Godden and Baddeleys findings
accurate recall was 40% lower in conditions 2 and 3 ), compared to conditions 1 and 4
what where the conclusions of Godden and baddeleys study
in conditions 2 and 3, the external cues available at learning were different from the ones available at recall and this led to retrieval failure.
who studied research into state-dependent forgetting
Carter and Cassaday (1998)
what was Carter and Cassaday procedure
Participants learned lists of words/passages of prose and later recalled them.
Participants given antihistamine drugs which had a mild sedative effect, making the participants slightly drowsy.
This creates a different internal state from the ‘normal’ state of being awake and alert.
what where Carter and Cassaday’s conditions
1: learn when on drug and recall when on drug
2: learn when on drug and recall when not on drug
3: learn when not on drug and recall when on drug
4: learn when not on drug and recall when not on drug
what where Carter and Cassaday’s findings
Recall was significantly worse in conditions 2 and 3 where there was a mismatch between internal state at learning compared with conditions 1 and 4.
concluded that when the cues at encoding are absent at retrieval there is more forgetting.
