Q

declarative

A

require conscious recall

17
Q

strength of different types of memory

A

brain scans have shown separate locations in the brain for each of the three types of memory supporting the idea of different kinds of memory
episodic-right prefrontal
semantic-left prefrontal
procedural-motor area

18
Q

strength of different types of memory

A

people who experience loss of memory due to brain damage lose only certain kinds of memory
amnesiacs like CW support LTM types
most of his procedural but not his episodic memories were intact

19
Q

weakness of different types of memory

A

types of LTM are difficult to separate so it may be an oversimplification eg our episodic and semantic memories are very closely linked in some case for example our facts about a singer may be linked to an event such as a concert you went to

20
Q

bartletts study aim

A

to see how memory is reconstructed when recalling a familiar story

21
Q

bartletts study method

A

war of the ghosts study was read by one participant and asked to recall 15 mins later then showed new version to other participant and so on (serial reproduction)
belonged to a culture that was very different to theirs

22
Q

bartletts results

A

participants remembered different parts
interpreted story within their own frames of social and cultural expectations to make it make sense
story was shortened
phrases used were changed to their own culture’s language
recalled version became fixed

23
Q

bartletts conclusion

A

don’t remember details remember fragments then use knowledge of social situations to reconstruct memory
remembered meaning as reconstructed version is simpler to remember

24
Q

weakness of bartletts study

A

conducted casually with no set standards in where and how people recalled
Gauld and Stephenson 1967 study found recall more accurate when participants were told that accurate recall was important from beginning

25
Q

weakness of Bartletts study

A

own beliefs are likely to have affected way he interpreted data
analysed each type of recall and had to decide if it was accurate
since he believed that recall is affected by cultural expectations he is more likely to see that effect

26
Q

weakness of bartletts study

A

story was unusual
may not reflect everyday reconstruction process
in everyday life our memory usually is not affected by cultural expectations
tells us little about everyday life

27
Q

theory of reconstructive memory

A

people rebuild memory as an active process
fragments of info remembered and then rebuilt into meaningful whole

28
Q

social and cultural influences on reconstruction

A

info that didn’t fit with their frames were transformed

29
Q

effort after meaning

A

focus on meaning of events after make effort to interpret meaning in more familiar terms

30
Q

strength of theory of reconstructive memory

A

support by bartletts
study reflects how memory works in everyday life which is more realistic than remembering word lists which are artificial
social origins of memory were obscured in artificial memory

31
Q

weakness of theory of reconstructive memory

A

wrong to suggest all memories are inaccurate
personal and distinctive events people remember accurate detail
people do not always actively reconstruct memories

32
Q

strength of theory of reconstructive memory

A

explains problems with eyewitness testimony
study showed memory is always accurate so eyewitness testimony can’t fully be trusted and relied on

33
Q

inference

A

forgetting when two memories compete with each other

34
Q

context in memory

A

contact of learning acts as a trigger cue when trying to remember
context enhances accuracy

35
Q

false memories

A

act of imagining a memory can implant false memory into someone’s mind
false memories act as an example of reduced accuracy in memory
