Memory Flashcards
Memory
Memory is the ability to take in information, store it, and recall it later. This information takes many forms including images, sounds and or meaning. It is a record of experience that guides future action.
Storage
Where information is stored in the brain
Duration
How long a memory lasts for
Capacity
How much can be stored at any time in each section
Retrieval
The process of recalling information to use. Can either be intentional remembering or a passive recall.
Retrieval Cue
A retrieval cue is a stimulus that initiates remembering. These can be external (e.g., an image, text, or scent) or internal (e.g., a thought or sensation). Cues can be encountered inadvertently or deliberately sought in the process of deliberately trying to remember something.
Recall
Retrieving information from memory with few if any cues. Example: completing a test.
Recognition
Correctly identifying or selecting previously learned information from a set of alternatives. Example: Completing a multiple-choice question. Easier than recall.
Sensory Memory
Extremely brief storage of information from each of the sense, in a relatively unprocessed form. Most immediate form of memory.
Duration: couple of seconds
Sensory Registers
The individual subsystems of sensory memory. The sensory registers include sound, touch, sight, smell, and taste (the five senses). Information is stored in each register for only a few seconds.
Iconic and Echoic memory
Iconic Memory
Brief memory of something just seen, duration of 1 second and can store up to 20 memories/items (capacity).
Echoic Memory
Brief memory of something just heard, duration 3 seconds and can store up to 1-2 memories/items (capacity).
How is sensory memory transferred to STM?
Information is passed from the sensory memory into short-term memory via the process of attention, which effectively filters the stimuli to only those which are of interest at any given time.
Short Term Memory (STM)
Memory system that receives and encodes new information from sensory memory and receives information from long term memory for temporary use. Holds all the memory you are currently thinking about or are consciously aware of.
Duration and Capacity of STM
Duration: approximately 20-30 seconds
Capacity: 5-9 items can be in STM
