Process of memory Flashcards
Atkinson-Shiffrin multi-store model
Represents memory as consisting of 3 separate stores: sensory memory, short-term memory, long-term memory
Encoding, Storage and Retrieval
- explain in relation to the Atkinson-Shiffrin model
Sensory information from external environment is sent to sensory memory, which requires attention to be sent to STM.
Short-term memory is rehearsed to be encoded and sent to LTM. If not rehearsed, it is lost from STM.
Information can then be retrieved from LTM and be sent to STM.
Sensory memory
- function
- capacity
- duration
Receives sensory information from the external environment
Capacity - potentially unlimited
Duration - 0.2-0.4 seconds
Short-term memory
Receives information from sensory memory and transfers information to and from LTM.
Capacity - 7±2 pieces of information
Duration - 18-20 seconds. possibly up to 30 seconds
Long-term memory
Information storage for re-access and use at a later time
Capacity - Potentially unlimited
Duration - Potentially unlimited
Types of sensory memory
- explain each
Iconic memory - Visual sensory information that lasts for 0.2-0.4 seconds
Echoic memory - Auditory sensory information that lasts 3-4 seconds
Types of long-term memory
Explicit memory
- Semantic memory
- Episodic memory
Implicit memory
- Procedural memory
- Classically conditioned memory
Explicit memory
Memory that is consciously retrieved.
Semantic memory
Facts and knowledge
Episodic memory
Personally experienced events
Implicit memory
Memory that is unconsciously retrieved
Procedural memory
Motor skills and actions previously learned
Classically conditioned memory
Memory that involves conditioned responses to conditioned stimuli.
What are the brain regions involved in the storage of LTM?
Hippocampus
Cerebral cortex
Amygdala
Cerebellum
Types of explicit memory
- Semantic memory
- Episodic memory
