Q

Describe Baddeley’s model

A

Working memory is affected by Language, reading speed, and word length.

Central executive ->
visuospatial sketchpad (visual ST memory)
visual info stored as objects
limit 3-4 objects
If you remember one feature of an object, you get all
the other features for free
there is a linear relationship between object complexity and objects remembered

Q

What are the typical tests for explicit vs implicit memory?

A

Explicit:
Typical tests: Recognition, Recall

Implicit:
Typical tests: Word completion, Word Identification

Exposure increases activation, even if no explicit memory
Previous exposure to rare words increases likelihood they are reported EVEN if subjects don’t recall seeing the word before!

24
Q

What are types of amnesia?

A

Anterograde Amnesia (H.M)
– Inability to form new explicit memories
– Ability to form new implicit memories
– Damage to Medial Temporal Lobes (hippocampus)
Anterograde amnesia often involves retrograde amnesia

Retrograde Amnesia
– Inability to recall old memories, especially
episodic memories
– Damage to brain regions outside of the Hippocampus

25
Q

Describe Clive wearing

A 
Cause of amnesia ->herpes encephalitis
 - damage to hippocampus
Preserved cognitive abilities
- intelligence
- skillsplaying piano and conducting

Anterograde amnesia
has no episodic memories

feels he is awake for the first time over and over. Memory lasts 2 minutes.

Clive, who, for all his musical powers, needs “close direction” from others. He needs someone to put the music before him, to get him into action, and to make sure that he learns and practices new pieces.

26
Q

Is All Memory Impaired in Anterograde Amnesia?

A

Patients with Anterograde Amnesia can form new nondeclarative memories (e.g. Tower of Hanoi,
Mirror Drawing) without explicitly remembering the task.

27
Q

Costs and Benefits of Schemas

A

The Good
• Provides framework within which to remember an event • ‘chunking’ since don’t have to remember all details
The Bad
• Can lead to misremembering a specific event via generalizations or confusion

28
Q

Flashbulb memory

A

“flashbulb” memories are not special, but they are emotional and usually rehearsed more than ordinary memories
• Show same forgetting as any other memory

29
Q

What are the 4 theories of categorization?

A

Categories
Category membership determined by necessary and sufficient conditions (All-or-none category membership)

Prototypes
Concepts defined by ‘ideal’ or ‘average’ member

Exemplars
Concepts defined by previously seen examples
Better than Prototype for context effects and ad-hoc categories

Theory-driven
Concepts defined by constructing theories
Use background knowledge and causal relationships to determine category membership

30
Q

levels of categories

A 
Superordinate
   Fruit
Basic
   Apple
   Basic level can be ‘imagined’
   First words that come to mind
Subordinate
   Gala, Fuji, Honeycrisp
31
Q

What is VSD system?

A

modality-specific input system that stores representations corresponding to the form or shape of objects, and which is used to access conceptual information

32
Q

How do you test for category impairments?

A 
• Picture naming
• Sound identification 
• Object decision
• Parts decision
- Central-attribute judgments
- Visual processing (e.g., visual matching & face recognition to measure general processing of visually complex stimuli)
33
Q

Intrusion errors are typically caused by?

A

BACKGROUND KNOWLEDGE BROUGHT TO A SITUATION

34
Q

Connections among our various memories do all of the following except

A

HELP US TO RESIST SOURCE CONFUSION

35
Q

What is Deese-Roediger-McDermott Paradigm (DRM)?

A

Very simple task that leads to large numbers of memory errors (activating a single word that is not actually on the list of words; i.e. “sweet” in a list of “cookies,” “chocolate,” “creamy,” “sugar,” etc.)

36
Q

According to interference theory, most forgetting is attributable to the fact that

A

NEW LEARNING DISRUPTS OR OVERWRITES OLD LEARNING

37
Q

Which of the following is true about autobiographical memories?

A

RECONSTRUCTION OF PAST EVENTS WILL OFTEN BE CONSISTENT WITH CURRENT VIEWS OF SELF

38
Q

The external validity of an experiment is BEST expressed by the following:

A

RESULTS ARE GENERALIZABLE TO DIFFERENT GROUPS OF PEOPLE AND SITUATIONS

39
Q

Flashbulb memories are extremely detailed, vivid memories usually associated with highly emotional events. The accuracy of these memories seems

A

BEST PREDICTED BY THE CONSEQUENTIALITY OF THE EVENT TO THE PARTICPANTS’ LIVES

40
Q

In one procedure, participants were asked to judge which was a better even number, “4” or “18”-

A

MADE THE JUDGMENT IN A FASHION THAT IMPLIED A GRADED MEMBERSHIP FOR THE CATEGORY

41
Q

Categorization models based on family resemblance rely on:

A

FEATURE OVERLAP AMONG THE MEMBERS OF A CATEGORY

42
Q

Which of the following statements about converging evidence is true?

A

IT IS IMPORTANT TO FIND CONVERGENCE FROM A VARIETY OF TASKS AS WELL AS THE LIMIT ON THE CONVERGENCE

43
Q

What are 4 differences between working memory and LT memory?

A

working memory is limited in size, LT memory is vast

getting info into WM is easy, just think about it

getting info out of WM is easy

the contents of WM is fragile

44
Q

Where are working memory and LT memory located

A

LT in the hippocampus

WM in the perirhinal cortex

45
Q

working memory holds how many chunks?

A

7 plus or minus 2

46
Q

random, read

A

WM is best thought of as a status, not a place

Operation span is a measure of WM capacity

The intentional to learn adds little to memory performance. What matters is how people approach the material they are seeing or hearing.

learning can be good for one sort of retrieval and bad for other sorts of retrieval

context reinstatement - improved memory performance if we recreate the context that was in place during learning
deep but unmatched context is inferior to not so deep but matched

Encoding specificity - what you remember = the stimulus + its context and meaning

Different retrieval paths can = different meanings of what is remembered

47
Q

maintenance vs elaborative rehearsal

A

maintenance is rehearsing items with little though about meaning or how they relate to each other

elaborative rehearsal is opposite

48
Q

intentional learning vs incidental learning

A

intentional learning is learning with an intention to learn (know you will be tested later)

incidental is learning without the intention to learn

49
Q

Processing fluency

A

use of a pathway increases the processing fluency of the pathway - that is, the speed and ease with which the pathway will carry activation
can explain implicit memory priming

50
Q

What is the feeling of familiarity?

A

when increased processing fluency, the stimulus will feel special and distinctive

if you’ve seen something recently but it does not feel familiar:
you detect the fluency but attribute it to a different source and therefor cant experience the sense of familiarity

if you havent seen it recently but it still feels familiar:
when the processing of a stimulus is more fluent than you expected, for example if the stimulus was presented a few ms longer than other stimuli. The processing of the stimulus is unexpectedly fluent and you seek an attribution for this fluency, and you are fooled into thinking its familiar

51
Q

Read

A

Retrieval paths have a starting and ending point. to use the path u must return to the starting point.

network. A node becomes activated when it receives enough of an input signal to raise its activation level to its response threshold

Activating one node primes nearby nodes though spreading activation

Source memory is essential for reacall; recognition can be achieved either through source memory or through familiarity

52
Q

What factors shape memory>

A

involvement with an event, emotion, passage of time

53
Q

False memories

A

Intrusion errors - errors in which outside knowledge intrudes into the remembered event (ex. DRM)

False memories are more easily planted if the subject dont just hear about the false event, but also imagine it

False memories = misinformation effect

False memories can be just as emotional as real ones

A feeling of remembering is more likely with correct memories than false ones. However, remembering is not a reliable means to distinguish real from false memories

Real memories are recalled more rapidly (response speed) than false memories

No reliable method to distinguish real from false memories

54
Q

Forgetting

A

Hypnosis and drugs do not improve memory recall

55
Q

Autobiographical memory

A

Self-reference effect - memory advantage for materials pertaining to the self

Emotion aids memory consolidation

Flashbulb memories are not necessarily correct

56
Q

Knowledge

A

graded membership - objects closer to a prototype are better members of the category than objects farther away

converging operations

57
Q

Read, memory

A

Mnemonic strategies can help and hurt memory.

Explicit memory can overshadow implicit memory
