L7-9 Flashcards
what are the three types of memory?
- episodic memory
- semantic memory
- procedural memory
what is episodic memory?
- memory for important events
- stored in hippocampus
contains three elements:
- specific details of the event
- context of the event
- emotions you were feeling @ the time of event
what is semantic memory?
- memory for facts + general knowledge about the world
- stored in temporal lobe
- also relate to e.g. functions of an object, what behaviour is appropriate in a certain situation or abstract concepts such as maths + language
- semantic memories begin as episodic memories = acquire knowledge based on personal experiences
- gradual transition from episodic –> semantic when memory slowly loses its association to particular events + is generalised
- HOWEVER, sometimes ppl can have strong recollection of when + where they learned a particular fact
what is procedural memory?
- aka muscle memory
- memory for motor skills + actions e.g. tying shoe laces/ knowing how to read
- stored in cerebllum
- acquired through practice + repetition = resistant to forgetting or amnesia than other types of LTM
- less aware of them = become automatic + unavailable for conscious inspection (unlike semantic + episodic) = difficult to explain verbally
- if you think too much about procedural memories = prob prevents from carrying it out
where is the episodic memory stored?
hippocampus
where is semantic memory stored?
temporal lobe
where is procedural memory stored?
cerebellum
what are some ads for LTM? (ep, sem, proc)
- evidence for distinction between ep/sem + proc has come from research on patients w/ amnesia
= patients w/ amnesia are unable to store ep/sem memories but proc memory unaffected - scientific evidence captured from brain scans supports the view that there are diff types of LTM = when asking parts to recall diff types of info, diff areas of the brain are shown active on fMRI = ep, hippocamus… sem, temporal lobe… proc, cerebellum
- case studies of brain damaged patients support diff types of LTM = Clive Wearing suffered from viral infection which damaged hippocampus = no ep memory + can’t form sem memories BUT proc memory unaffected
what is a disad of for LTM? (ep, sem, proc)
- case studies and research are only isolated cases of one individual = can’t assume that everyone’s LTM is formed in same way –> can’t be generalised
what is forgetting?
forgetting refers to a person’s loss of ability to recall or recognise something that they have previously learnt
what is the interference theory?
interference theory claims that forgetting occurs when two lots of information become confused in memory
- most likely to occur when two lots of info are similar to one another
- less likely to occur when there is a gap between the instances of learning
what is retroactive interference?
when new learning affects the recall of old info
what is proactive interference?
when old learning affects the recall of new info
what are the ads of interference theory?
- underwood (1957) investigated proactive interference = found parts who learned 10 lists of words could only recall 20% from first list the next day
- parts who learned 1 list of words recalled over 70% of words the next day
- McGeoh and Mcdonald (1931) demonstrated retroactive interference = gave parts lists of words that they had to learn until 100% recall
- parts learned new list = either synonyms or antonyms –> then asked to remember o.g. list = pats who learnt synonyms list had worst recall as similar meanings caused interference
- theory has practical applications = students made aware that shouldn’t revise similar content/subjects @ same time = interference most likely to occur
what are some disads of interference theory?
- when interference occurs, loss of info may only be temporary –> interference may not be true explanation for forgetting as info isn’t acc over-written + still is in LTM
- some psychologists argue that retrieval failure is a much better explanation of forgetting in everyday life than interference
- theory states that we forget when there aren’t enough retrieval cues to help us remember
- Godden + Baddeley (1975) got divers to learn + recall in the same context = better remembered ad retrieval cues in environment
