explanations of forgetting Flashcards
when does interference occur ?
when one memory disrupts the ability to recall another
explain proactive interference
- causes forgetting of new information
- prior learning what we already know distrupts the ability to recall current new learning
what did keppel and underwood research
proactive interference
explain keppel and underwoods research
- participants were presented with trigrams and asked to recall them after differnt time intervals
- to prevent rehersal during the time interval, participants were asked to count back in three’s
- results found that participants forgot the triagrams which appeared at the end of the list regardless of the interval time delay
what did keppel and underwood’s research suggest about interference ?
- old learning had interfered with the recall of the new most recent trigrams
- the participants forgot the new information, supporting proactive interference
explain retroactive interference
- causes forgetting of old information
- current new learning distrupts the ability to recall prior learning and what we already know
what did McGeoch and McDonald investigate ?
retroactive interference
explain McGeoch and McDonald’s research
- participants were asked to learn a list of words untill they could recite them perfectly
- participants were then divided into 6 groups, 5 of which were asked to learn another set of interfering information, and one controll group was asked to rest
- participants were then asked to recall the words from the first list
In which condition did the most forgetting occur
synonyms
what does McGeoch and McDonald’s research suggest about interference
- the more simular the information the easier it is forgotten
- as these words were learned first the old information was forgotten
baddley and Hitch
interference
- investigated retroactive interference
- rugby players were asked to recall the names of opposing teams who recently played
- recall for the last played games were good despite the length of time since it had been played
- forgetting occured for naming teams in rugby teams who had frequently played and low recall for teams from early in the season
- when more simular info exists, more likely to be confused - players forgot the older teams due to new info
strength of interference
supporting experimental
I: supporting evidence for the concepts within the interference theory of forgetting from experimental research
E: Keppel and underwoods study
C:demonstrates that interference is a valid explanation of memory
strength of interference
supporting natural
I: further supporting evidence for the interference theory of forgetting from natural experience
E: baddley and hitch’s study
C: demonstrates interference is a valid explanation as it has strong supporting evidence supporting retroactive interference
strength of interference
practical applications
I: practical applications in education based on research from interference theory forgetting
E: knowledge about how forgetting occurs can be used to try and prevent it.
to avoid forgetting in students, individuals should engage in regular practice of knowledge, and try to make the information appear as different as possible to stand out from other information, so the chance of memories becoming confused is reduced
C: demonstrates that research based on interference can help improve the lives of people in areas of education
weakness of interference
limitations
I: limitations of the interference theory in explaining forgetting
E: whilst interference can explain many examples of forgetting, the theory does not adequatley explain the actual cognitive processes involved in forgettingor explain how much forgetting can soley be attributed to interference
C: alternative theories of forgetting may provide a more comprehensible account of forgetting
what is retrival failure ?
- forgetting occurs due to the absence of cues.
- cues serve as a reminder of what we are trying to remember - as cues were encoded at the time of learning
what is the encoding specificity principle
memory is most effective when information present at the time of encoding is also present at the time of retrieval
what are the three types of cues
- semantic cues
- context-dependent cues
- state-dependent cues
what are semantic cues
- cues often have a meaningful link to information that is being learned
- forgetting occurs when the recall does not link to understanding at encoding
explain Tulving and Perlson’s research procedure
- ppts were given worlds to learn that belonged to certain categories
- during recall stage one group were given the category heading and one group free recalled the words
what was the findings of Tulving and Perlsons research
the free recall group forgot 90% of the words compared to the category heading group who forgot 40% of the words
what did Tulving and Perlson conclude about their research
forgetting occurred due to the absence of category heading cues
what are context dependent cues
- external cues such as the environment we were in at the time of learning can remind us of the material we learn
- forgetting occurs when recall in the environment is difficult to where learning took place at encoding
explain Baddley’s procedure
- participants who were deep sea divers were asked to learn 36 words either on the beach or underwater
- they then recalled the words either on the beach or underwater
