Models for explaining memory Flashcards
Includes: processes of memory, multi-store model of memory, and working memory model
Memory
The process of encoding, storing and retrieving information
What are the 3 processes of memory?
Encoding, storage, and retrieval
What is the process of encoding?
The process of converting information into a form that can be used and stored by the brain.
It may be automatic or require effortful processing
What is the process of storage?
Retention of encoded information for various lengths of time.
Via associations between neural networks
What is the process of retrieval?
Recovery of information stored in brain.
If memory cannot be retrieved, it can not be shown to exist
What are the 3 characteristics of memory?
Duration, capacity, and encoding
Duration
The length of time information can be stored/held for
Capacity
The amount of information that can be stored/held
Encoding
The form information is stored in (visual/acoustic/semantic)
Sensory memory
Briefly holds incoming sensory information
Different subsystems: sensory registers (for each sense)
What is the duration of sensory memory?
0.5 to 3 seconds
What is the capacity of sensory memory?
Unlimited - but generally referred to as 3 to 7 units
Sensory memory register
Rapid encoding based on physical properties of sense/stimuli (environmental input)
Stores incoming sensory information receptors
What is the short-term memory?
A component of memory where information is retained for a brief amount of time, then some is encoded and transferred into LTM
What is the duration of short-term memory?
0-30 seconds
