Q

long term memory

A

information (when rehearsed) can stay in the memory for up to 100 years

21
Q

procedural LTM

A

responsible for knowing how to do things, also known as motor skills

22
Q

semantic LTM

A

process ideas and concepts that are drawn from personal experience

23
Q

episodic LTM

A

a persons unique memory of a specific event, so it will be different to everyone else’s

24
Q

retroactive interference

A

new memories have an effect on trying to receive older traces

25
proactive interference
old memories have an effect on trying to receive new memories
26
give 3 problems with studying memory
- impossible to clear the mind - you cant see it - everyone's mind is different
27
give 3 ways of studying memory
- brain scans - repeated measures experiment - different samples
28
give the order of the multi store model
sensory-short term-long term
29
Sterling experiment (1960)
aim-short term and sensory memory findings-higher percentage on 'tones column' than any other conclusion-higher on tones procedure-flashed 12 letters for 1/2 a second and had to recall in 3 different ways
30
give 2 criticisms of the sterling experiment
not realistic | short amount of time
31
digit span experiment-Jacobs (1887)
aim-capacity of digits and letters STM procedure-lab experiment,presented with increasingly longer lists had to recall in right order findings-digits 9.3 items, letters 7.3 items conclusion-DTM capacity is 7+/- 2
32
give a criticism of the digit span experiment
low ecological validity-lab
33
what is chunking
extending items by adding meaning, which extends the capacity of STM
34
trigram experiment
aim-test duration STM method-lab procedure-3 letters to remember, given a number they had to count back from, after a certain amount of time they had to recall the letters results-90% correct 3secs, 20% correct 9sec and 2% correct 12secs
35
give the order of the WMM
add image
36
strengths of WMM
- isn't too much to remember | - if they aren't all using the same slave system it is easier to remember
37
what is trace decay theory of forgetting
forgetting occurs as a result of the automatic decay or fading of the memory trace
38
what is interference theory
memory disrupted or interfered by what we previously learned
39
what is lack of consolidation
memory relies on biological processes-changes to the nervous system
40
what is retrieval failure
information is in long term memory but cannot be acsessed
41
what is context/external cues
context-setting or situation
42
what is eye witness testimony
legal term given for an individuals account of a crime in the court of law
43
what did Loftus experiment
false memories and how memory can fail to receive key information-false information created by the individual
44
what is a directional hypothesis
suggests a relationship between independent and depended too variable-suggests direction of result
45
what is a non-directional hypothesis
doesn't suggest the relationship between the variables
46
loftus and palmer 2 experiments
add image
47
what influences EWT
- gender - anxiety - misleading questions - schema
48
yerkes dobson effect
add image
49
what is individual differences
a variable on the experiments is emotional sensitivity
