Explanations For Forgetting Flashcards
Interference
Interaction between new material and transfer effects of past learned behaviour memories or thoughts that have negative influence in comprehending new material
Proactive interference
Old memory interfered with a new one
Retroactive interference
Newer memory interferes with older one
Effect of similarity
Evidence for interference theory
McGeoch and McDonald
Retro active interference Learned list of words until 100% remembered then learned new list / 1) synonyms 2)antonyms 3)words unrelated to original ones 4)nonsense syllables 5)3digit numbers 6)no new list, rest / When recall original list of words, performance depended on nature of 2nd list Interference stronger when memories similar / Closer words are, lower the recall
Strengths of explanations for forgetting- interference
Support real life studies
Lab experiment
Weakness of explanations for forgetting - interference
Research artificial- used word lists which aren’t relevant to every day life
Interference only explains some situations of forgetting
Doesn’t occur that often
Retrieval failure
Occurs due an absence of cues
Based on idea that the issue relates to being able to retrieve memory that is there but not accessible
Context dependent forgetting
Failure to recall information without memory cues
External
Environment
Research evidence Godden and Baddeley for CDF
Investigate effect of environment on recall
/
18 divers asked to learn list of unrelated words
Con1)learn on beach recall on beach
Con2)learn on beach recall under water
Con3)learn under water recall on beach
Con4)learn under water recall under water
/
Findings showed recall was better where learnt
/
Context acted as a character
State dependent forgetting
Information stored in memory is retrieved by way of association with other memories
Internal
Research evidence carter snd Cassaday for SDF
Investigate effect of physiological state on recall
/
Given anti histamine drugs, mild sedative effect making participant drowsy.
Learn list of words and passage then recall info
Con1)learn on drug recall on drug
Con2)learn off drug recall on drug
Con3)learn on drug recall off drug
Con4)learn off drug recall off drug
/
Recall better when in same physiological state
Strengths of retrieval failure
When environment and state is different more likely to forget
Relevant to real world
Weakness of retrieval failure
Don’t always work- in experiments use words that aren’t meaningful
Lacks ecological validity
Lab experiment
