Interference Flashcards
(20 cards)
What’s interference
One memory disrupts the ability to recall another resulting in distortion or forgetting
When is interference likely to occur
With similar memories
What’s the two types of interference and explain them
Proactive interference: Previously learnt information interferes with new information
Retroactive interference: New memories interferes with older ones
What’s the Retroactive study
Mcgeoch and Mcdonald 1931
What’s the Retroactive study aim
aim: research retroactive interferences affects of similarity
What’s the Retroactive study conditions
conditions : group 1 (synonyms) group 2 (antonyms) group 3 (unrelated) group 4 (nonsense syllables) group 5 (3 digit numbers) group 6 (original list only)
What’s the Retroactive study method
Gave participants a 10 word list to remember, then a new word from 1/6 conditions.
What’s the Retroactive study findings
findings: chronological order from groups form worst to best recall.
What’s the Retroactive study conclusion
Conclusion; Similar materials interfere stronger than dissimilar.
What’s the Retroactive study strenghs
Scientific
Internal validity
Controlled
amalysable
What’s the Retroactive study weakness
Lab study so no external volatility
Artificial task
Whats underman and postmans 1960 study’s procedure
Group A: Learned a list of paired words then a second list
Group B: Only learned first list
Both asked to recall first list
Whats underman and postmans 1960 Aim
See if new learning interferes with old (retroactive)
Whats underman and postmans 1960 findings
Group B recall was more accurate than A
Whats underman and postmans 1960 Conclusion
New learning interferes with old
Whats underman and postmans 1960 Advantage
Internal Volatility
Lab study
Controlled
see cause and effect
Whats underman and postmans 1960 Disadvantages
Low temporal volatility Artificial Tasks No mundanrealsim Lab study Doesn't research if memory that is forgotten can be recovered Not applicable to real life
What the strengths of interference
- Lab study’s are controlled and scientific giving it scientific volatility.
- Supportive study’s from Baddeley and hitch
- Controlled so can see cause-affect
- Internal Volatility
What’s the weaknesses of interference
- Lab study so artificial therefore not applicable to real life
- not generalisable
- no external volatility
- dose not account for nature of material remembered
- Baddeley stated tasks where too similar which isn’t likely in real life.
- Lack of retrieval study’s
What did Baddeley and hitch 1977 do
Asked rugby players to recall names of recently played teams which varied in time intervals (1-7 days)
- Found equal recall no matter the time
- Showed incorrect recall not due to decay but intervening games.
- Show interference as a reason for forgetting.
