responsible for processing verbal and auditory info
temporal lobe
- phonological store: a temporary storehouse (inner ear)
- articulatory loop: for active rehearsal (inner voice)

Q

evidence of phonological loop

A
  • syllabic word length effect: word span for longer words is smaller than for shorter words, harder to rmb words with more syllables than fewer syllables
  • articulatory word length effect: processing can be affected by articulation duration (apart from the number of syllables)
  • articulatory suppression: results in a reduced verbal span when people speak while simultaneously trying to remember a set of items
  • irrelevant speech effect: phonological loop is less efficient when there is irrelevant speech in the background, even if it is in a language people do not understand
  • phonological similarity effect: phonologically similar items are more likely to lead to errors

Q

episodic buffer

A

where multimodal information from different parts of working memory are combined or bound together

  • a limited capacity storage system that brings together information from other parts of working memory as well as LTM
    • binds info about verbal, auditory, visual, and spatial and this forms a more cohesive and coherent memory (episodic memory, and event)

Q

central executive

A

the control centre, has additional capacity to devote to a subsystem if needed

  • involved in allocation of attention
  • actively processes info/manipulate contents of phonological loop and visuospatial sketchpad
  • distributes memory resources
  1. focus
  2. divide
  3. switch

Q

dysexecutive syndrome

A

people lose some central executive functions
- perseveration: when people have been doing a task one way and need to do it another way, but the switch is not made
- distraction: when people are supposed to be attending to one task, but some elements of the environment take attention away from it
- illustrates the lack of attentional control

Q

name and explain the span tasks

A

reading span test: read aloud 2-6 sentences, at the end of each set, recall the last word

comprehension span test: read sentences and make sensibility judgments (does the sentence make sense), recall the last word in each set

operation span test: read aloud 2-step math problem then indicate whether the solution is correct, after that a word is presented, recall as many words from the set as possible

spatial span test: series of letters are shown that have been rotated, initial task is to indicate if the letter is normal or mirror image, then indicate where the top of the letter was pointing

Q

levels of representation

A
  • surface: captures verbatim text (decays rapidly)
  • text base: abstract representation of text, meaning or context (shows decline between 1-7 days later)
  • mental model: represent the state of affairs described by the text rather than the text itself, 5Ws 1 H (durable)

Q

episodic retrieval cues

A
  • feature cue: involve components of memory itself (self-reference)
  • context cue: things in the environment (smell)

effectiveness of cue depends on how diagnostic the cue is not the degree of overlap with the original cue

Q

Deese-Roediger-McDermott (DRM) effect

A

a conventional experimental methodology for examining false memories

  • this paradigm involves the presentation of associated words (bed, rest, etc.), which induce a false recall and/or false recognition of a non-presented word (critical lure; sleep)

Q

why distributed > massed

A
  • consolidation account: massed practice is inferior bc consolidation has not run its course, in distributed practice, there is more consolidation
  • deficient-processing account: massed practice reflects a processing deficiency, get habituated during massed prac, more mind wandering, we assume that info is alr learned and do not devote time and effort to actually learn it
  • contextual variability account: differences in the variability of the contexts stored with the memories is what accounts for the differences in massed and distributed practice, different contexts allow for more retrieval pathways
  • study phase retrieval account: when we have subsequent study sessions, this reminds us of prior sessions allowing connections to be made btwn them

Q

Von Restorff effect

A

isolation effect
- among similar items, distinctive items are remembered better
- leverages on item-specific processing

32
Q

retrieval practice (tetsting) effect

A

memory is better if ppl practise retrieval after initial study than if they simply restudy

33
Q

what happens if there is feedback/none when testing?

A

no feedback –> direct effect, forgetting decreases
feedback –> indirect effect, increase in metacognitive awareness, increased benefit from re-encoding, forgetting decreases and retention increases

34
Q

elaborative retrieval hypothesis

A

the testing effect occurs bc testing causes ppl to engage in deeper processing while taking the test
- increases retrieval routes

35
Q

episodic context account

A

retrieval reinstates prior learning context, updates the contextual representations with current context to constrain future search
- make new retrieval pathway for every new context learned in

36
Q

relational processing hypothesis

A

involves making connections, help organise material and improve performance, helpful in generating a retrieval plan

37
Q

bifurcation model

A

attempts to account for direct effect (without effect during testing phase)

38
Q

dual memory framework

A

separated memories are formed during study and retrieval practice phases that increase retrieval routes

39
Q

fuzzy trace theory

A

different traces capture different info, multiple traces work together to contribute to what is remembered

40
Q

adaptive memory

A

evolutionary pressures, memories evolve to serve particular environmental issues
- ppl respond faster to words based on their subjective level of danger or usefulness

41
Q

animacy effect

A

bias for rmbing animate objects better than inanimate

42
Q

prospective memory

A

remembering to do things in the future

43
Q

event-based prospective memory

A

a need to rmb to do smthg when some event occurs

  • influenced by the relation btwn the event that signals you to rmb the action
  • better if the event and action are more related → like write needle when you hear thread
  • harder when there are multiple cues → need to watch out for more cues, only when all is present then you do the action, then u get distracted
44
Q

time-based prospective memory

A

need to rmb to do smthg at a certain time or after a certain time interval

  • rmb to call someone at a certain time (meeting etc)
  • harder than event-based → bc theres no physical cue in the environment its a concept of time
  • improve time-based by making it event-based → setting a buzzer (buzzer acts as a event that u are looking out for)
  • ppl make more errors if the task is repetitive
45
Q

location-based prospective memory

A

do smthg when they are in a particular place

  • change in location acts as a cue
  • focal: part of on-going task
  • non-focal: not part of on-going task → here, attention is divided, some cognitive control is needed
46
Q

activity-based prospective memory

A

do smthg upon completion of an activity

47
Q

difference between prospective and retrospective memory

A

involves
- monitoring the environment for the cue
- rmb what to do in the future
- retrieve the memory of what to do
- actually do it
- requires more cognitive control

48
Q

episodic future thinking

A

involved when we imagine or plan for what may happen in the future

49
Q

constructive episodic simulation hypothesis

A

using prior episodic memories of similar experiences to guide what we imagine the future will be like

50
Q

semantic memory

A

general world knowledge

51
Q

conceptual knowledge

A

knowledge that enables us to recognise objects and events and make inferences about their properties

52
Q

category

A

a set of entities that can be treated as though they are equivalent

53
Q

concept

A

mental representation of a category

54
Q

taxonomic relations

A

based on shared features

55
Q

thematic relations

A

based on co-occurrences, the overall themes, these set of items occur together

  • faster than taxonomic
  • more for abstract concepts
56
Q

levels of categorisation

A

basic –> the one we think of most of the time
subordinate –> most detailed
superordinate –> least detailed

57
Q

classical view of categorisation

A

idea that categories are defined by necessary and sufficient features

  • necessary: features must be present
  • sufficient: if they are present, they are a member, additional features are unnecessary
58
Q

problems with classical view of categorisation

A
  • not all categories have the same set of necessary and sufficient features
  • does not account for family resemblance
  • does not account for central tendency
  • category membership is graded
59
Q

prototype view of categorisation

A

categories are defined by a mental representation that is an average of all category members, decisions are based on how close an example is to the prototype

60
Q

problems with the prototype view

A
  • conveys only central tendency
  • no concept of category size and variability
  • caricatures can facilitate categorisation than prototypes
  • circular
61
Q

exemplar view of categorisation

A

people use all category members to make decisions

  • sensitive to context
  • sensitive to frequency and central tendency
62
Q

problem with exemplar view

A

circular

63
Q

explanation-based view of categorisation

A

categories are theories or explanations

  • ppl use knowledge to understand how the members of a category form a coherent grp
  • ppl place more emphasis on causes rather than effects
    → grp things based on what it does (function) or what it can do
64
Q

psychological essentialism

A

the idea that members of a category share an underlying essence, of which we may or may not be aware → this leads to having stereotypes and prejudices

65
Q

what are ordered relations?

A
  • semantic distance effect: ppl make judgments faster abt the order of 2 concepts as the distance btwn them increases → the difference is more obvious so its easy to discriminate them
  • semantic congruity effect: when the direction of the comparison coincides with the location of the stimuli on the continuum (smaller is on the left)
  • serial position effect: ppl are faster to make judgements about 2 or more concepts at the extremes of a dimension than those in the middle → easier to see that ant is smaller than a mouse vs a sheep and dog bc ant is rly rly rly v small so is cnfm smaller than wtv alr
  • SNARC effect: judgments about smaller numbers (whether they are odd or even) are faster with the left hand and faster for bigger numbers with the right hand
66
Q

SNARC

A

spatial-numerical associative response codes

67
Q

schema

A

highly organised general knowledge structure for a familiar domain

68
Q

script

A

temporally ordered schemas that are structured according to the major components of the event

69
Q

operations of a schema

A

SAIIR

selection: identify what is relevant
abstraction: convert info to a more abstract and basic form (to capture underlying meaning)
interpretation: fill in the gaps
integration: guide to put the pieces together
reconstruction: recreate the initial memory but paraphrased with additional info and details (filled in gaps)

70
Q

nondeclarative memory

A

collection of various forms of memory that operate automatically and accumulate information that is not accessible to conscious recollection

eg
- conditioning
- procedural skills
- priming

71
Q

implicit memory

A

memory for a previous event or experience that is produced indirectly without an explicit request to recall the event and without awareness that memory is involved

72
Q

how to assess implicit memory

A
  • priming
  • lexical decision
  • word-stem/word-fragment completion
  • perceptual identification
73
Q

stages of skill acquisition

A

CAA

cognitive stage: consciously and deliberately perform the actions of the task
associative stage: can retrieve the knowledge needed to do the task more quickly
autonomous stage: largely unconscious

74
Q

triarchic theory of skill learning

A

MCR

metacognitive system –> most engaged when we first learn new skill (cognitive stage)
cognitive control system –> (associative stage)
representation system –> neurons get more wired together (autonomous stage)

75
Q

positive transfer

A

learning of one skill facilitates learning of another skill

76
Q

negative transfer

A

learning of one skill interferes with the earning of another skill (like proactive interference)
