Q

-Episodic + working memory impaired
-Semantic + procedural memory intact
-This supports the idea that there are different types of memory that engage different brain systems

A

Q

Iconic memory: Afterimages

A

Helpful for seeing things smoothly
-We see 75 frames/second
-Movies are 24 frames/second
-View movies as a smooth event
-Your afterimage is filling in gaps

Q

Negative afterimage

A

I visual memory is the (colour) inverse of the perceived image
-Slightly longer than positive afterimage (few seconds)

Q

Primacy Effect

A

-You will remember first names on a list the best
-First names being rehearsed more
-Rehearsal in short term memory makes a long term memory

Q

Chunking strategy

A

Grouping items together in a meaningful way

21
Q

The Chunking Effect

A

-Chunking increases with knowledge
-Expert chess players recall more pieces on a chess board than new chess players
-This effect is not present if the pieces are on the board randomly

22
Q

Working Memory

A

Retention and manipulation of information not in our environment
-Essential for many cognitive functions
1. Central Executive
2. The Phonological Loop
3. Visuo-Spatial Sketchpad
4. Episodic Buffer

23
Q

Central Executive

A

Conscious awareness of information

24
Q

The Phonological Loop

A

-Phonological Store
-Articulatory Control Loop

25
Phonological Store
Passive store for verbal information ''The inner ear'' -Holds on to information
26
Articulatory Control Loop
Active rehearsal of verbal information ''The inner voice'' -Mentally saying something to yourself -Used to convert written material into sounds (reading) -Specialized role in language
27
The Viusospatial Sketchpad
-The visual cache -The inner scribe -Can be associated with what + where pathways
28
The Visual Cache
Information about visual features
29
The Inner Scribe
Information about spatial location, movement and sequences
30
Neuroimaging Evidence
Different areas of the brain are active for visual and verbal working memory tasks
31
Double Dissociation in Neuropsychological Cases
-Patient ELD has problems recalling visual-spatial but not verbal material in the short term -Patient PV has problems recalling verbal but not visual material in the short term
32
The Episodic Buffer
Integrates information from short- and long-term memory -E.g. how we can hold someone's face + name together in mind
33
Implicit Memory
Playing the piano and tying your shoes are examples of...
34
Explicit Memory
Remembering your firs piano lesson, knowing the french word for Burrito and thinking about the ski trip you took last weekend are examples of...
35
Ebbinghaus
Learned nonsense syllables, tested memory at various intervals, and examined what was retained (forgotten)
36
The Forgetting Curve is exponential
Memory loss is largest early on and slows down -Fastest right after you learn something
37
The Spacing Effect
Forgetting is reduced when learning is spread over time -Explanation : Repeated information is more valuable -Lesson : Don't cram
38
Active Rehearsal + The Testing Effect
Test yourself to learn better
39
Levels of Processing Theory
The strength of a memory (and potential for forgetting) depends on processes engaged at encoding -Memory is stronger with deep processing
40
Shallow processing
Focus on sensory information -E.g. upper or lower case sounds of words
41
Deep processing
Integrate higher-level knowledge (things we know) with learned information -E.g. if word is synonym of another word if words related to themselves or not
42
Mnemonics
Organizational strategies to help encode information, link new information to prior knowledge -Chunking stategies -Acronyms to remember lists -Imagery and the Method of Loci
43
Method of Loci
Use a familiar image to link encoded information together
44
Decay Theory
Memories are lost over time due to disuse -Like a muscle you don't use, a memory gets weaker
45
Interference Theory
Interference is responsible for much of forgetting -Encoded memories are liable and need to be consolidated into stable long-term memories -During pre-consolidation period, memories are suscptible to disruption and effects of interfering information
46
Proactive Interference
Prior information interferes with encoding a new memory -E.g. trouble learning a new phone number because your old number keeps popping up in your memory
47
Retroactive Interference
Newly learned information interferes with a prior encoded memory -E.g. trouble remembering an older password after you formed a new password
48
Similarity Effects
The more alike something is to what is already learned, the more it will mingle and interfere with memory -E.g. if you want to remember an episode of Severance... cook some stew afterwards rather than watch another Adam Scott show
