Memory Flashcards

1
Q

What are flashbulb memories?

A

vivid, more detailed reconstructions (even for most dearly held ones)—you remember exactly where you were and what you were doing when it happened; e.g. JFK assassination, 9/11, Challenger explosion

Q

Why is memory considered reconstructive?

A

Our memory is often reconstructed based on the information available at recall; however, this doesn’t always lead to correct recall

Flashbulb memory inconsistencies

A

the narrative changes at first, but more times you say something, the more you believe its true and stick to that version

Q

What is Immediate memory?

A

A system that actively holds onto a limited amount of info so it can manipulated and processed (for a brief time); the contents of consciousness
-also “short-term” or “working” memory

Q

What is the Inner voice?

A

the small voice inside your head that you hear when you try to count to 10 in your head
-its evidence for verbal representation in memory
- mistakes that we make support the inner voice
- if you can’t speak, you don’t have an inner voice
-‘cheese for please’ mistakes; don’t look alike, do sound alike

Q

What is Duration?

A

Q

What is rehearsal?

A

the process or repeating info to yourself; helps you re-hear it and maintain it indefinitely; without it you quickly forget info

Q

What is Capacity?

A

how much we can hold in our minds at once; over the short term, this limit is 7 +/- 2 items or what you can rehearse in 2 secs (called memory span)
-meaningful chunking can condense info

Q

What is Baddely’s working memory model?

A

a model of immediate memory that emphasized its role as a system for manipulating information in consciousness:
central exec which coordinates the;
-phonological loop (controls inner voice- auditory/verbal info)
-visuospatial sketchpad (controls inner eye- visual/spatial info)
- C.E. also coordinates the flow of info b/w working and long-term memory

What is Sensory memory?

A

a system that keeps information translated by the senses in a relatively unaltered, unexamined form; includes echoic and iconic forms of sensory memory

Q

What is the encoding specificity principle?

A

the idea that retrieval cues are only useful as long as they match the original context of how to-be- remembered info was originally learned

Q

What is “Deep” processing?

A

encoding new info via meaningful connections to existing knowledge (e.g. is this a living four-legged furry creature?)

22
Q

What is Representation?

A

the kind of information a memory system contains

23
Q

What is “Shallow” processing?

A

encoding new info based only on its surface characteristics (e.g. capital letters or not)

24
Q

What can we do to improve memory?

A

spaced repetition (retrieval), easier to remember living > non-living things, same with survival > vacation processing, mnemonics (peg-word, loci method, acronyms)

25
What are cues?
pieces of info that help us remember events from the past -cues are only helpful if they match the to-be-remembered i.e. target) info
26
What is Hyperthymesia?
a rare medical condition that leads to near-perfect autobiographical recall; characterized by larger amygdala with more connections to hippocampus
27
What is Retrograde amnesia?
loss of memories prior to a specific traumatic event such as a blow to the head or other conditions; usually only temporary and for the events immediately prior to injury
28
What is Anterograde amnesia?
inability to encode new info into long-term memory; typically permanent and results from extensive damage to hippocampus
29
What is Déjà vu (misattribution)? an EOC
the feeling that one has already experienced a sequence of events; "already seen"
30
What is the Misinformation effect (suggestibility)? an EOC
a phenomenon in which misleading info alters a subsequent memory; typically refers to an eyewitness account
31
What is the use of Schemas (bias)? an EOC
highly organized knowledge structures, e.g. stereotypes, which can influence recall for info relevant to the stereotype
32
What is PTSD (persistence)? an EOC
characterized by memories that are difficult to suppress, despite conscious effort to do so; flashbacks
33
What is the Interference theory of forgetting?
memories become irretrievable because they're obscured by other, competing info; more evidence for this theory e.g. you forget the name of the first person you met at a party yesterday because you met 5 other people that night too
34
What is the Decay theory of forgetting?
memories fade away due to the passage of time alone; very little evidence e.g. you forget the name of the only person you met at a party yesterday without rehearsal
35
What are errors of omission?
memory errors where info cannot be brought to mind
36
What is the modal memory model?
37
What is transience?
memory for any particular event tends to degrade over time
38
What is absent-mindedness?
memories are simply unavailable bc of a failure to encode them in the first place
39
What is blocking?
lack of distinctive cues are available to help us recover a specific memory
40
What are errors of commission?
memory errors where wrong/unwanted info is brought to mind; misattribution, suggestibility, bias, persistence
41
What are the results of practicing retrieval?
Practicing retrieval is much more effective than dropping and restudying; even by practising retrieval just a few extra times you remember a lot more
42
What is retrival practice? Why is it the best way to learn/retain new info?
without looking at your notes, practice recalling concepts (you can use your own cues) repeatedly (repeating allows changing/adding to knowledge about info and making more connections ea time)
43
What are some useful kinds of elaboration?
imagery, organization, distinctiveness, self-reference
44
Cued vs free recall
free- write all the words you remember from the list vs cued- write all the words you remember from different groups/categories (cued is more effective)
45
What is transfer-appropriate processing?
use same kind of mental processes during testing as study (encoding) to enhance retrieval (e.g. do practice in same format you'll be tested in)
46
What is implicit memory?
remembering without conscious realization or intent -explicit is conscious, willful remembering -elaboration has a reduced effect on implicit memory
47
What is the Inner Eye?
the mental experience of seeing something using your imagination - evidence for visual representation in immediate memory - its easier to remember smth bigger than smaller - inner eye and inner voice operate similarly to perceptual system (recruit same areas of brain)
48
What is an encoding-retrival match?
cues are only helpful if they match the target info (what you're trying to remember); you're more likely to recall target when cues present at study (encoding) are similar to those at test (retrieval)
49
What is EOM 1?
transience: memory for any particular event tends to degrade over time
50
What is EOM 2?
absent-mindedness: memories are simply unavailable due to a failure to encode them in the first place
51
What is EOM 3?
blocking: not enough distinctive cues are available to help us recover a specific memory
52
What is episodic memory?
contents pertain to specific events/ episodes; includes most autobiographical memories
53
What is semantic memory?
contents pertain to specific facts/concepts without personal experience; semantic=meaning
54
What is procedural memory?
contents pertain to how to do something; incl. most athletic & motor skills
