Sensory memory
The entry point of memory where information that is later stored is first detected by your senses
What is the capacity and duration of sensory memory?
Sensory memory has a duration of 0.2-4 seconds and unlimited capacity
What are two types of sensory memory?
Iconic memory (visual information) and echoic memory (auditory information)
Iconic memory capacity and duration
Capacity- Unlimited
Duration- 0.3-0.4 seconds
Echoic memory capacity and duration
Capacity-Unlimited
Duration- 3-4 seconds
Short term memory
A store of memory that holds a limited amount of information that is consciously being attended to and actively manipulated
Short term memory capacity and duration
Capacity- 5-9 items
Duration- 18-30 seconds
How can STM capacity be manipulated?
Chunking
How can STM duration be manipulated?
Rehearsal
Chunking
A process of combining small pieces of information into more meaningful, larger groups of information (chunks).
Maintainence rehearsal
a memory strategy that involves repetition of information repeatedly to keep it in STM
Elaborative rehearsal
a memory strategy that involves linking new information with existing information already in storage in a meaniful way to transfer STM to LTM
Long term memory
A store of memory in which a potentially unlimited amount of information is stored for a relatively permanent amount of time
Capacity and duration of LTM
Capacity- Unlimited
Duration- Relatively permanent
Strengths of model of memory
-Model distingusihes between different stores involved in memory
-The model outlines that each memory store has a different capacity and duration
Limitations of model of memory
-May be considered to be too oversimplified
-The model does not account for individual differences in memory processes, duration and capacity
Two types of long term memory
Explicit and implicit
Explicit memory
A type of long term memory that is consciously retrieved
Two types of explicit memory
Semantic memory and episodic memory
Semantic memory
A type of explicit memory that consists of gerneral knowledge and facts
Episodic memory
A type of explicit memory that consists of personal experiences and events
Implicit memory
A type of long term memory that is unconsciously retrieved
Two types of implicit memory
Procedural memory and classically conditioned memory
Procedural memory
A type of implicit memory that involves knowing how to carry out tasks
