Q

what is short term memory and how is the info stored

A

stores small amounts of information for a brief durartion
- only 15sec-20sec if not reherased
- the info is stored acoustically rather than visally

25
what does the episodic buffer allow us to do
allows us to solve problems and evaluate previosu experience with knowldge we recently gain
26
what are the four major methods for studying the brain
- behaviour after brain damange -single cell recording -measuring activity in the brain -recording electrical signals from human brain
27
what part of the brain is responsible for processing incoming visual and auditory information
prefrontal cortex BUT working memory involves processes beyond the prefrontal cortext, communication between many parts of the brain
28
greater working memory= ______
greater working memory= greater congnitive processes
29
what is long term memory
an archive of information about past events and knowledge learned
30
what does long term memory work closley with
working memory
31
what are the two types of long term memory
explicit (conscious) implicit (not conscious)
32
korsakoffs syndrome
unable to form new long term memories - result of chronic alcoholism and the destruction of cells in frontal and temporal lobe
33
3 examples of functioning STM but no new LTM
Clive wearing H.M E.P
34
what is the serial position curve
memory is better for stimuli presented at the beginning= primicy effect memory is better for stimuli presented at the end= recency effect curve looks like a U with the start of the list and the end of the list having higher percent recalled
35
what is the predominant type of coding long term memory and then two other types
predominate type= semantic coding - remembering the gist of an event, not the exact wording other -Auditory= remembering the sound of someones voice -Visual= remembering someones face
36
declarative
conscious recollection of events experiences and facts learned -store and reteive personal info (episodic memeory) and general knowelge (semantic)
37
episodic memory vs semantic memory
Episodic memory= memory from personal events - this involves metal time travel and there is NO guarentee of acuracy Semantic Memory-= facts and knowelge - there is NO mental time travel and its general knowldge They both activate different areas in the brain
38
describe K.C
K.C had damange to his hippocampus - no episodic memory ( cant relive any memeories from the past) - but semantic memeory is intact, so he knows general knowledge about the past
39
describe the italian women
lost semantic memory, so she can not remember meaning of words - she retained eposodic memoery so she can recall events from her past
40
Semantics can be enhanced if associated with episodic , give an example
Autobiographical memeory memories for specific experiences from our life have both semantic and episodic components Personal semantic memeories= facts associated with personal experiences
41
three types of long term memory
episodic, semantic, and autobiographical
42
intacct semantic and episodic memory may be required to think about _______
personal future
43
contructuve episodic simulation hypothesis
episodic memories extracted and recombined to construct simulations of future events
44
what is implicit memeory and whwen does it occure
memeory that unconsciously influences behaviour - occurs when some previous experiences influences out performance on a task "nonknowing"
45
what are the three types of implicit memeory
priming procedural memeory classical conditioning
46
what is priming
presentation of one stimulus affects performance on that stimulus when it is presented again - positive priming= causes an increase in speed or accuracy
47
what are the two types of positive priming
repetition priming- when the test stimulus is the same or resemebles the priming stimulus conceptual priming- occurs when the enhancement caused by the priming stimulus is based on the meaning of the stimulus
48
korsakoff syndrome
memeory disorder which is due to lack of vitamine B1, often associated with alcoholism - when tested on memory, the persons performance imporves even though the person does not remember the training
49
propaganda effect
more likely to rate statements read or heard before as being true
50
what is the pocedural memeory of implicit memory
memeory for actions (think muscle memory) no memory for where or when learned - preformes procedures without being consciously aware of HOW to do them ex) mirror tasks conclusion= people who can not form NEW LTM can still learn new skills
51
classical conditioning and how it relates to implicit memory
pairing a neurtral stimulus with a reflexive response - a conditioning stimulus that does result in a response ex) the lady who got shocked when shaking hands and didnt remember doing it, but then after a couple times she didnt want to shake hands, but didnt know why she didnt want to
52
Melton, three stage framework
encoding - processes of information acquisitin Storage- successful formation of a memory trace (more of a holding space than a process) Retreival- accessing information in memeory they are all connection no encoding= no stroage= no retreival
53
what are some factors that affect encoding
Attention-- critical, not attending= not encoding repetition (practice)= the more you encounter some piece of information the easier it will be to remember
54
what are the two types of repetition
massed repetition- repeted repetion close in time ex) studying for an exam the night before distributed repetion- repeated presentations spead out in time ex) studying throughout the semester
55
"the spacing effect", and two reasons why this is true
refers to the benefit of distributed repetition over massed repetition defiecient processing view - locus is at encoding -with massed rep you dont pay much attention after the first presentation and thus only one encoded representation rather than many encoding variability view -locus is at retreivial -with massed rep there is no variability in how repeated events are encoded
56
what is the illusion of learnning
familiarity does NOT = knowledge
57
differentiate between rehearsal and repetition
repetition refers to repeated experiences with a stimulus rehersal refers to how stimuli are thought about internally
58
what are the two types of rehersal
maintenance rehearsal (cramming) -repeating the information before and up to use - maintains information but does not transer to LTM elaborative rehearsal (thinking about meaning) - thinking about the meaning of an item or making connections between the item - transfers information to LTM
59
incidental vs intentional learning conditions
incidental = learning something without knowing you will be tested on it intentional = they are told there will be a test
60
differentiate between maintenece and elaborative rehearsal
Eleborative -active learning -involves meaning -linking to other info in LTM - transfer to LTM Maintenance -passive learning -no meaning -no linking to LTM -usually stays in STM
61
how does how "deep" the info is processed affect memory?
the deeper the information is processed the greater likelihood it will be remembered
62
forming _____ improves encoding, and what does this support
forming visual images Duel code theory= encoding occurs in 2 different systems (visual and phonological)
63
what is the generation affect
generating information rather than passivly receiving it enhances learning and attention note: tie the infor to yourself or someone you know will make it personal and you will remember it better
64
what is retrieval
process of tranferring information from LTM back into working memeory (consciousness)
65
testing effect
enhanced performance due to testing (learning that is retained over longer period of time) and retreval practice -creating your own test questions -generating own study guide
66
what are four different types of retreival cues
objects related to information - drive by the grocery store environment related to info -grandmas house word related to info -apple, then grape emotion related to memeory -smell of choc chip cookies
67
two types of recall procedures
free recall- participants asked to recall stimuli previously presented cued recall- cue presented to aid in recall **note: retreival cues are most effective when created by the person who uses them
68
encoding specificity principle, and the outshining hypothesis
we encode information along with its context ex) studying and being tested in the same environment can positivly affect recall However, the outshinning hypothesis states that knowldge trumps encoding specity so the environemnt only matters if you dont know the info
69
state dependent learning
learning is associated with a particular internal state ex) listening to sad music and then writing test in sad environment = better test scores
70
transfer appropriate processing two conditions two tests types
focus is on what is required at retrieval two conditions= deep processing (semantic) ex) word fits into the sentence medium processing (phonological) ex) do these words rhyme ** Both conditions create durable memory traces, but contain different info two test types standard recognition ex) was this word previously encountered rhyme recognition ex) recognize words that rhymed with words encoded earlier
71
regarding transfer appropriate processing, Both conditions create durable memory traces, but contain different info--- explain
there is two condition types deep processing (semantic) and medium processing (phonological) semantically encoded words should be remembers better on the standard test phonological encoded words should be better remembered on the rhyme recognition test
72
consolidation
new memories are FRAGILE and can be disruped thus, Consolidation= the process that transforms new memories from a fragile state in which they can be disrupted to a more permanent state in which they are resistant to distruption
73
differentiate between retrograde amnesia and anterograde amnesia
retrograde- loss of memory for envents prior to the trauma **graded amnesia= memory for recent events is more fragile than for remote events, thus memeories from further back come back easier than closer memories because they were fragile Anterograde- cannot form new memories
74
relationship between sleep and consolidation
- reduces environmental interference - enhances consolidation
75
couple reasons why studying for a test the night before doesnt work
informormation wont be moved into LTM -no consolidation -maintence rehersal -only encoded once -no sleep= poor attention and increase anxiety levels
76
what is reconsolidation
process that occurs when a memory is reactivated. similar to consolidation but more rapid reactivation makes memory fragile and vunerable to distruption, which can then be reconsolidated
77
reactivation and reconsolidation in PTSD patients
reactivating followed by reconsolidation alleviates anxiety and physical symtoms associated with flashbacks - doesnt remove the memory, but helps remove the physical response which can then allow the patient to talk about it without the physcial tramma
