Explanations of forgetting Flashcards
What is forgetting?
Failure to retrieve memories
What is retrieval failure?
Explanation for forgetting when material is stored in the LTM but can’t be consciously recalled as a result of a lack of retrieval cues to jog the memory
What is the interference theory (IT)?
Forgetting is due to information in LTM becoming confused with other info during coding, leading to inaccurate recall.
What are the 2 forms of interference?
Proactive and Retroactive
What is proactive interference?
Works forward in time, occurs when info stored previously interferes with an attempt to recall something new eg memory of old number disrupts attempt to recall new number
What is retroactive interference?
Works backwards in time, occurs when coding new info disrupts info stored previously, eg memory of new car registration number prevents recall for previous one
What is the procedure for Schmidt et al’s remembering street names study?
211 pps, ages 11-79 given map of neighbourhood with all 48 street names replaced with numbers & asked to recall as many as possible.
Other personal details were collected.
The amount of retroactive interference experienced was assessed by the no. of times they moved to other neighbourhoods.
What are the findings for Schmidt et al’s remembering street names study?
There was a positive association between the no. of times pps had moved house and no. of street names forgotten.
What are the conclusions for Schmidt et al’s remembering street names study?
Learning new patterns of street names when moving house makes recalling an older pattern harder.
Retroactive interference can explain forgetting in some real-life situations.
Give evaluations for Schmidt et al’s remembering street names study
Extraneous variables may have affected the results, eg those who played a lot in the neighbourhood may have learned the street names better than those who didn’t play.
Evaluate the IT
It only explains forgetting when 2 sets of info are similar eg learning French and welsh at school, this doesn’t happen often - so IT can’t explain forgetting in the majority of real life settings.
Research tends to use lab experiments - lacks mundane realism.
When does Cue-dependent forgetting occur (CDF)?
Occurs when info is still in LTM but can’t be accessed. Recall is dependent on retrieval cues, its dependent on accessing info by remembering the retrieval cue under which info is stored.
What is the encoding-specificity principle and who created it?
Where recall is hindered if the context of recall is different to that at coding. Tulving.
What are the 2 main forms of CDF?
Context-dependent failure & state-dependent failure
What is context-dependent failure?
Occurs with external retrieval cues, where forgetting occurs when the external environment is different at recall from how it was at coding
