explanations for forgetting Flashcards
What is meant by interference?
One memory disturbs the ability to recall another. This might result in forgetting or distorting one or the other or both. More likely to happen when the memories are similar
What are the two types of interference?
Proactive and Retroactive
What is proactive interference?
Previously learnt information interferes with the new info you are trying to store.
e.g trying to learn names of new psychology class but instead using names of last years students
What is retroactive interference?
A new memory interferes with older ones. For example you have difficulties remembering the names of your psychology students last year because you have learnt the new ones
Who researched into interference?
Underwood and Postman (1960)
What was Underwood and Postman’s aim?
To find out if new learning interferes with previous learning
What was Underwood and Postman’s procedure?
Participants were divided into two groups
Group A were asked to learn a list of word pairs i.e cat-tree then asked to learn a pair of words where only the second was changed e.g cat-glass
Group B were asked to learn the first list of word pairs only
Both groups were then asked to recall the first list of word pairs
What were Underwood and Postman’s results?
Group B’s recall of the first list of words was more accurate than group A
What was Underwood and Postman’s conclusion?
Suggests items in the second list interfered with participants ability to recall the list. This is an example of retroactive interference
Strengths of interference
Research to support from Underwood and Postman
Baddeley and Hitch asked rugby players to recall opponents they had played, players who had played more had worse recall (interference) - real life application
Limitations of Interference
Research is artificial and mainly completed in lab experiments
Interference does not answer the question of if access or availability is the issue
Effects of interference may be overcome by giving people cues to help them remember
The loss of information may only be temporary so this might not be a true explanation of forgetting
What are the two types of cues?
Meaningfully linked to the info to be remembered
Not meaningfully linked to the info to be remembered
What is meant by context dependent forgetting?
When we learn the information, we also encode the context (external cues) in which we learn the information. Context dependent forgetting can occur when the environment during recall is different from the environment you were in when learning
What is meant by state dependent forgetting?
We also learn the mental state we are in (internal cues). State dependent forgetting occurs when your mood or physiological state during recall is different from your state when we were learning. Should these cues not be present this can cause retrieval failure
Describe Tulving’s ‘Encoding Specificity Principle’
The greater the similarity between the encoding event and the retrieval event, the greater the likelihood of recalling the original memory
