- FORGETTING
- lack of consolidation
- Blow to the head or chemical disruption/consolidation cant happen
- it is a structural change = cause by neural acitivty
- consolidation is required for into to LTM
- study
- American footballers. They were concussed and asked at different time periods
- Motivated forgetting
- traumatic experiences are repressed into unconscious
- we forget because we want to
- Study
- Williams
- 129 woman
- abused 10mths - 12years
- interviewed 18-31yrs
- 38% not recall
- Williams
- evaluation
- unfalseyeable - cant be tested if right or wrong
- cant explain how some people still recall unpleasant events clearly
- normally recall more pleasant than unpleasant memories but we may rehearse pleasent
- might not be due to repression don't want to talk.
- Displacement
- 7+-2 capacity
- if full, push out
- only applies to STM
- Study
- serial position
- 21 words
- recall
- serial position
- Evaluation
- fits with multistore model
- tasks emvolved are artificial - learning list of words
- Lost popularity when the working model was introduced
- only STM not comprehensive, theory of forgetting
- Trace Decay
- with time / no rehearsal engram breaks down
- when we learn a structure change occurs (engram)
- Study
- presented with pts with trigram
- rehearsal was prevented with a distractor
- fond a decline in recall after 30seconds - no trigram recalled
- evaluation
- we don't know if the forgetting was due to time / distraction
- cant explain how people can remember events from years ago but was never rehersed
- cant explain why people who may not have recalled straight away but not after
- interference
- similar information causes memory to be confused
- 2 types
- retroactive
- current learning affects old
- retroactive
- 2 types
- Evaluation
- tasks are artificial learning list of words = lacks ecological validity but rugby players = field study
- interference depends on the similarity material, it does not occur occur often with material not similar
- no real explanation of why it occurs and the cog processes involved
- does have a role in forgetting but we are unsure of the extent
- similar information causes memory to be confused
- retrieval failure
- information in LTM is available it cant be accessed unless appropriate cues
- context
- state
- organisation
- study
- learn words in water/dry land
- recall same environment or not
- recall better in the same enviroment learnt from
- evaluation
- it fit with what we know about levels of processing because cues involve deep processing
- sometimes just imagining the context where it was learned is just as good.
- everyone has experiences the tip of the tounge phenomena
- diver study lacks eco validity because the task is too artificial
- information in LTM is available it cant be accessed unless appropriate cues
- lack of consolidation
- lack of consolidation
- Blow to the head or chemical disruption/consolidation cant happen
- it is a structural change = cause by neural acitivty
- consolidation is required for into to LTM
- study
- American footballers. They were concussed and asked at different time periods
- Rehersal helps
- Evaluation
- not sure how long it takes
- most everyday instances do not involve blow to head
- field study = high eco validity
- link bio & psy
- consistent with what we know about nervous system
- proactive
- 2 types
- retroactive
- current learning affects old
- retroactive
- earlier learning affects currents learning
- 2 types
- study
- similar information causes memory to be confused
- played games throughout season
- asked who they played
- those who played a lot forgo more than those who played fewer
- similar information causes memory to be confused
