explainations for forgetting - retrieval failure Flashcards
retrieval failure
don’t have the necessary cues to access memory. memory is available but not accessible until there is a suitable cue
who found the encoding specificity principle
tulving in 1983
encoding specificity principle
- cues have to be present at coding and present at retrieval
- if there is a different cue present= forgetting
when are cues used
in mnemonic techniques
context dependant forgetting
recall depends on external cue
state dependant forgetting
recall depends on internal cue
who conducted research on context dependant forgetting
godden and baddeley - 1975
context dependant fogetting research procedure
divers learnt and recalled a list of words either: learnt on land-recalled on land, learnt on land-recalled underwater, learnt underwater-recalled on land, learnt underwater-recalled underwater
findings for diver experiment
recall was 40% lower in non-matching environments
different ext. cues at learning and recall= retrieval failure
who conducted research on state dependant forgetting
Carter and Cassaday - 1998
state dependant forgetting procedure
- antihistamines used to make participants feel drowsy
- learnt and recalled list of words either: learnt on drug-recalled on drug, learnt on drug-recalled without drug, learnt without drug-recalled on drug, learnt without drug-recalled without drug
drug experiment findings
- if there was a mismatch in the internal state at learning and recall, performance on the test was lower
- if cues are absent, increases chance of forgetting
strength - real world applications
- retrieval cues can overcome some forgetting in everyday situations
- to reverse forgetting, try and recall initial environment where learning occurred
research reminds us of strategies used in everyday to recall info
strength - research support
range of research to support retrieval failure showing that it occurs in everyday life and the lab
who conducted negative research support
baddeley 1997
