Q

Atkinson-Shiffrin three stage memory model

A

involves sensory, short-term, and long-term memory
external stimuli — sensory memory, which is encoded into short-term mem with attention, which is encoded into long-term memory storage with active maintenance, where it is able to be retrieved into working memory

processed into short term memory

Q

automatic processing

A

unconscious encoding of incidental info - produces implicit + procedural memory (e.g. riding a bike)
involves three items (STFu):
Space - visualize location
Time - know sequence of events
FreqUency - remember how many times something was done

Q

What are some key methods of effortful processing?

A

chunking: organizing info into personally meaningful, smaller units. often automatic
mnemonics: memory aids that use vivid imagery + org as technique (REHUGO)
hierarchies: processing info in terms of broad categories + subdivisions into narrower concepts (e.g. flowcharts)

23
Q

episodic memory

A

explicit memory of experienced events

24
Q

What role does the frontal lobe play in memory processing?

A

Prefrontal cortex involved in working memory processing
right lobe: visuals
left: language (e.g. password)

25
Q

What role does the hippocampus play in memory processing?

A

processes declarative memory for storage
- stores info for recall later (e.g. birds caching food and finding later)
- NOT permanent (like a loading dock)

26
Q

memory consolidation

A

the neural storage of a long-term memory
memories migrate from hippocampus to other storage

27
Q

What roles do the cerebellum and basal ganglia play in memory?

A

cerebellum = implicit memory formation (e.g. cc associations)
basal ganglia = involved in motor movement and procedural learning - receives input from cortex

28
Q

infantile amnesia

A

not remembering declarative memories formed in early childhood
happens b/c immature hippocampus, etc.

29
Q

flashbulb memory

A

clear and sustained memory of emotionally significant event
happens because stress hormones boost brain activity (thanks to the amygdala), especially in memory forming areas

30
Q

LTP

A

long-term potentiation
an increase ina cell’s firing potential after brief, rapid stimulation, whereby after sensory neurons need less persuading to release NTs
neural basis for learning and memory
“neurons that fire together wire otgether”

31
Q

priming (u5)

A

unconscious activation of memory association
rpedisposes us to certain retrievals
e.g.
exposed to word “rabbit” for 1/10 sec
afterwards, hearing word “hair/hare” retrieves word “hare” more often

32
Q

mood congruency

A

tendency to recall experiences that are consistent with one’s good/bad mood
having a bad day? you recall other bad times … primes negative associations that we use to explain our current mood

33
Q

state-dependent memory

A

people remember more information if their physical / mental state is the same at time of encoding and time of recall
e.g. caffeinated when you lost your keys? may remember better if caffeinated.

34
Q

serial position effect

A

tendency to recall the first (primacy) and last (recency) items in a list

35
Q

encoding specificity principle

A

idea that memories are context-dependent (affected by cues specific to an event or person)
ex: not recognizing teacher in unfamiliar locaiton

36
Q

anteretrograde amnesia

mod 33

A

the ability to remember past events but inability to form new explicit memories
still able to form implicit/procedural memories

37
Q

retrograde amnesia

A

an inability to remember past events (cannot retrieve info)

38
Q

What are the main types of memory failure?

A

Encoding failure
Storage decay
Retrieval failure
Amnesia
Misinformation effect

39
Q

encoding failure

A

we cannot remember what we do not encode
lack of encoding effort + selective attention to pertinent info = forgetting

40
Q

storage decay

A

poor durability of stored memories = decay
Ebbinghaus forgetting curve - newly learned info is initially rapidly forgotten, then forgetting levels off w/ time (some memory discarded)

41
Q

retrieval failure

A

info is retained in memory store but cannot be accessed
tip-of-the-tongue effect (so close to being retrieved!)
retrieval cues (e.g. “it begins with an m”) = better accessed

42
Q

motivated forgetting

A

unknowingly self-censoring info
Freudian concept - relates to repression

42
Q

proactive vs retroactive interference

also significance of interference theory?

A

Proactive.Old.Retroactive.New.
old info disrupts recall of new info (e.g. locker)
new info disrupts recall of old info (e.g. lyrics)
interference stronger when material is similar (french-spanish, locker combo 2 locker combo)

43
Q

repression theory

A

motivated forgetting acts as basic defense mechanism that banishes anxiety-inducing memories from consciousness
controversial b/c no lab ev - hard to forget emotional events b/c flashbulb memories

44
Q

reconsolidation

A

when previously stored memories, upon retrieval, are potentially altered before being stored again
(“replaying memory” = slightly modifying it)
reactivating memory BUT stored differently

45
Q

Elizabeth Loftus

A

Bunny effect experiment (ppl falsely recalled meeting bugs bunny at disneyland) shows ppl subject to construction: fabrication of memories

46
Q

misinformation effect

A

incorporating false post-event info into one’s memory of an event
often fills in the gaps in our memory
leading questions lead to inaccurate eyewitness testimony b/c of this effect

47
Q

illusory memory / imagination

A

imagining nonexistent actions, which distorts our actual memory

48
Q

source amnesia

A

also known as source misattribution
faulty memory when it comes to how/when/where info was learned
ex: singer attributes lyrics to creativity BUT it’s plagarized from somewhere

49
Q

After hearing stories of things they both had and had not actually experienced with “Mr. Science,” preschool children spontaneously recalled him doing things that were only memtioned in the stories. This best illustrates:

A

source amnesia

50
Q

The inability to remember how Lincoln’s head appears on a penny is most likely due to a failure in:

A

encoding

51
Q

Police officers have been trained to ask less suggestive and more effective questions in order to avoid:

A

misinformation effect

52
Q

schema theory

A

idea that preconceptions bias the way new info is interpreted and recalled

53
Q

deja vu

A

the eerie sense that you’ve experienced a certain situation before

54
Q

How reliable are young children’s eyewitness descriptions?

A

Inaccurate w/ leading questions b/c easily molded and suggested (front lobe not truly matured)
BUT w/ more neutral language, accuracy improves
caveat - memories from 0-4 years are unreliable

55
Q

List some tips on how to improve your memory.

RMRMSS

A

repeat rehearsal
make material meaningful
recreate or retrace for retrieval
mnemonics … make ‘em!
study before sleep (and sleep lots!)
