Q

atkinson-shiffrin model S _ STM _ LTM

A

incoming sensory information is held in sensory memory (exact)

attention: moves to short term memory (consicous)

encoding to long term memory
retrieval moves back to short term

Q

semantic network theory

A

organisation of LTM is an interconnected grid of concepts

  • inter related
  • stronger the link, stronger the memory
  • more links to memory, stronger it is

34
Q

anterograde amnesia

A
  • damage to hippocampus
  • caused from brain trama
  • less likely to recover
35

forgetting

A

inability to recall stored information

-hermann ebbinghaus

36
Q

40% of information

A

is lost within 20 minutesl

37
Q

how to encode better 3

A

meaningful
connect to existing information
-be active in the process

38
Q

mnemonic devies 3

A

narrative chaining: make a story
acronyms: s.d.d.d
acrostivs, first letter is made into a sentence

39
Q

how to retrive better

A

  • visualize
  • related information
  • cues

context dependant cues

A

place/settings act as a retrival cue

41
Q

state dependant cues

A

physiological or psychological condtion in which the memory was made

42
Q

information least likely to forget

A
  • emotional memories

Q

serial position effect

A

superior recall for words at the start and end of a list

44
Q

primacy effect

A

first words heard, on the way to ltm

45
Q

recency effect

A

still in stm so easier to recall

46

primacy effect occurs but not the recency effect

47
