Q

double dissociation

A

functioning STM but cannot form new LTM
People with brain damage and impairment
Impaired long term memory because of damaged hippocampus and couldnt learn new things
hippocampus was removed on both sides due to epilepsy
no longer had seizure but long term memory
short term was fine

Q

recency effect

A

last words better
words are still in STM so didn’t have time to fade yet

Q

serial position curve

A

beginning shows output for LTM
Recency shows output of long term
Recency higher - last better than first

Q

importance of rehearsal for LTM: Rundus

A

number of rehearsals should be related with primacy effect
present words visually every five seconds
asked to say words aloud
count number of time each word repeats

Q

Rundus results

A

beginning there’s a good overlap probability related to repetition
second part of curve no relationship, no need to rehearse because in short term

Q

Murdock results

A

repeat more slowly have greater primacy effect
longer or shorter only changed in middle section
capacity should change due to length
neither does LT/primacy
present more slowly shape in the time
all condition have higher accuracy when slower presented
only changes primacy effect

interpretation

A

primacy/recency effect - very robust
effect on LTM but not on STM
one relies on rehearsal

Q

independence of double dissociation

A

two psychological constructs A and B can be shown to be independent if it is possible to devise an experiment X that will influence construct y that will influence construct B without affecting construct A

Q

Glanzer and Cunitz exp. 1 delay

A

adding a delay should reduce recency effect
if you keep busy and dont ask them to recall it fades
Standard: see all words on list
Delayed: see words, see digit, count, then recall

Q

Glanzer and Cunitz exp. 1 delay result

A

red line - standard
recency is not great, delay prevents it
primary is fine but stay flat at end

Q

Glanzer and Cunitz exp. 1 delay interpretation

A

asking them to count wipes short term memory
there was an interference, so they got forgotten
first items are still reported because in long term
primacy doesnt change

Q

Glanzer and Cunitz exp. 2 spacing

A

manipulated presentation rate
enhance primacy while maintaining recency

18
Q

Glanzer and Cunitz exp. 2 spacing results

A

1 word/ 6 sec is always more accurate then 1 word/3 seconds
recency not affected

19
Q

Glanzer and Cunitz exp. 2 spacing interpretation

A

long term and short term are independent memory
slow - increase primacy
slow - decrease recency bias

20
Q

types of LTM

A

explicit/declarative: conscious memory
implicit/non-declarative: unconscious memory

21
Q

explicit/declarative: conscious

A

episodic
semantic

22
Q

implicit/non-declarative: unconscious memory

A

procedural
priming - without conscious awareness

23
Q

episodic

A

personal events/episodes
specific events - time
personal experience
acquired immediately

24
Q

semantic

A

fact, knowledge
general facts
not tied to experience
acquired progressively

25
Q

K.C

A

motorcycle accident
no episodic memory
cannot relive any past events
semantic intact - general info

26
Q

Italian woman

A

encephalitis damaged her left temporal lobe
impaired semantic
preserved episodic
she didnt understand how the world works but remembered her memories

27
Q

Tulving, schacer and stark

A

effects the way you process words the next time
have memories you cannot verbally recall
forgotten at same rate - explicit

28
Q

Tulving, schacer and stark test 1

A

recognition - show them words and ask
was it on the list - recognition test
words with partial letters and ask to complete = word fragment completion
repetition priming effect - constant over time
repetition priming effect does not rely on explicit memory

29
Q

implicit memory

A

expressed through performance rather than conscious recollection

30
Q

classification of memory tests

A

explicit test: we ask the subject to access memory
implicit test: we dont ask but performance changed due to prior exposure

31
Q

Jacoby and Dallas interpretation

A

strong relationship between depth and explicit memory
no relationship between depth and implicit memory
dissociation between implicit memory and explicit memory

32
Q

amnesia

A

inability to form/recall memories
retrograde: past memories
anterograde: form new memories

33
Q

Graf, squire, mandler results

A

explicit memory of amnesic patients: significantly impaired

34
Q

propaganda effect

A

more likely to rate statements read or heard before as being true

35
Q

rating results

A

each line is different rating
lower rating means better

36
Q

Implicit memory, the news

A

define story then print it
if fake retract it later
buy things we dont need

37
Q

priming occurs when presentation of one stimulus

A

facilitates the response to another stimulus

38
Q

implicit memory preserved in

A

amnesia

39
Q

implicit memory is a

A

catch all term for memories that we are not aware of

40
Q

episodic

A

remebering
