Cognition Flashcards
Who gave the 3 box memory model
Other names for it
Atkinson and shiffrin
Information processing model
Multi store memory model
Explain the Information processing model
3 Stages - Sensory, Short term and long term
Explain the sensory stage of the info processing model
Duration
Capacity
How it moves to the next stage
Why is info lost
All sensory information around you.
Fraction of a second
Large capacity since there is so much information
Selective attention - Only when you pay attention to the information, will the memory move to short term.
Info lost because it is not encoded
What are the types of sensory information and their names
Vision - Iconic Auditory - Echoic Tactile - haptic Taste - Gustatory Smell - Olfactory.
What is the cock tail party effect
Demonstrates selective attention
At a party and someone in the distance calls your name. You don’t hear all the other conversations in the background until someone calls your name and has your attention.
Short term memory (multi store memory model)
Another name Duration Capacity How it moves to next How is info lost
Working memory
20 to 30 seconds
Limited - The magic number - 7 +/i 2
Moves to long term memory through rehearsal
Info lost because it is not encoded
What are the 2 types of rehearsal
Repetitive - rote learning
Elaborative - understanding the true meaning
Long term memory (3 box memory model)
Duration
Capacity
Why is info lost
Infinite time
Unlimited store
Info lost due to retrieval failure
What is the magic number (short term memory)
Who gave it
Capacity of the short term memory
7 +/- 2 things can be stored in the stm
George miller
Why does echoic memory last longer than iconic memory in sensory
Sounds travels slower than light and that lingers in the ear for a bit longer.
How to increase the capacity of STM
Using Mnemonics - memory aids that store things more efficiently
What are the types of mnemonics
Chunking
Acronyms
Imagery - form an image
Method of loci - form a mind map/cognitive map of diff items on list in sequence
Keyword technique - using rhyming or relatable terms to remember something.
What are the 3 types of LTM
Procedural
Episodic
Semantic
What are procedural memories
implicit or explicit
Declarative or non declarative
Conscious or unconscious
Memories of skills and how to perform them.
Implicit
Unconscious
Non declarative
eg: muscle memory.
What are episodic memories
Memories of specific events, stored in a sequential series of events.
Explicit
Conscious
Declarative
eg: graduation day, last bday party, etc.
What are semantic memories
General knowledge of the world, facts, meanings, etc.
Explicit
Conscious
Declarative
How do you remember explicit vs implicit memories
Actively try to remember explicit
Automatically and unintentionally remember implicit
How does eidetic memory work
Who studied
Make powerful enduring visual images in their mind
can remember things for long periods of time
Alexander Luria
What is the levels of processing model
Who gave it
explains why we remember what we do by examining how deeply the memory was processed or thought about
Craik and Lockhart
Types of memories in levels of processing model
Neither short term nor long term
Only shallowly processed or deeply processed.
What are shallowly processed memories
Types of shallowly processes
Another name of it
Only briefly processing the memory, will forget it later.
Structural - memorizing the visual structure of the memory
Acoustic - memorizing the sound of the memory.
aka Maintenance level
What is deep level processing
Aka
Process the information at the semantic (meaning) level
Understand its true meaning
Elaborative rehearsal
Aka: elaborative level processing
What does the working memory model talk about
who gave it
Talks about the short term memory in detail
Baddeley and Hitch
Try to draw a diagram
Central executive:
Phenological loops
Episodic buffer
Visuospatial sketchpads
All connected to central exec
What kind of memory does each part in working memory model store.
Visuospatial sketchpads
aka Inner eye
Hold all visual and spatial information
Phonological loop
Holds all the auditory information
What does the episodic buffer do
Puts visual, spatial and auditory information into 1 memory and transfers to LTM. Creates an ‘episode’ of memory.
What are the 3 steps of memory
Encoding
Storing
Retrieval
What are the 2 types of retrieval
Explain both
Recognitions - A clue is involved. Options are presented to you and you match them with your memory
Recall - completely remember the entire memory without any clue.
What is the serial position effect
Who gave it
The primacy effect + recency effect = serial position effect
refers to how the position of the information (read or heard) affects if its rem’d
Hermann Ebbinghaus
What is the primacy effect
Why does it work?
that we are more likely to recall items presented at the beginning of a list.
Those items have entered the LTM
What is the recency effect
Why does it work
ability to recall the items at the end of a list
Items are still in your STM
What is the ‘tip of the the tongue phenomenon’
Temporary inability to remember information.
EG: NAMES - you can describe everything about them, name starts with a t, black hair, wears glasses, but you can’t recall their name
