W1 Memory: processes + systems Flashcards
Memory
Faculty by which information is encoded, stored and retrieved when needed. Large vast, intangible
Memory processes
Encode, Store, Retrieve
Encode
Sights, sounds, smells = encode stimuli, things we perceive, and experience, don’t exist until your perceive them. Sensory representation.
Encoding = information enters memory system or slips away.
Store
Store representation. Storage = information is preserved for recollection in the future or is forgotten. We store this memory and when we want to bring memories back to the for front of our mind we retrieve memories things we recall.
Retrieve
Events, facts, skills retrieve memories (past trip, knowledge, riding bike) Retrieval = information is recollected or sits on the tip of your tongue.
A world without memory Clive wearing
= highly accomplished musician and conductor whe he fell ill with herpes simplex encephalitis, ever since Clive has lost the ability to form new memories or recall past memories. Damaged his past representation, loss of previous memory and enable to form new memories. He still retains the ability to play music. Different types of memories; his skill has been perceived. = Anterograde and Retrograde amnesia.
Memory taxonomies
Different types of memories we can organize
Categorise memories
Time ( model model of memory), content
Model Model memory
Sensory Memory (= input => a moment) => Short term memory (few seconds) =><= Long-term memory (permanent, not perfect). Sensory memory is either processed or lost. Sensory memory = modality-specific storage = different storage bins.
Sensory memory
Modality-specific storage of input from the sense (iconic + echoic memory)
Iconic memory
visual impressions
Echoic memory
Auditory impressions ( a few seconds)
Sperling’s (1960) experiments
= very brief presentation of letter arrays. Two conditions = whole report condition(= report as many as you can) + partial report condition (told which row to attempt to recall = performed this experiment with tones to indicate which row to recall).
Short term memory
attention to information moves in from sensory memory short duration (30-60s), capacity of 5-9 elements, boosted by active rehearsal and chuncking.
Long term memory
Information can be transferred from STM to LTM. Information can be retrieved from LTM to STM. Unlimited duration + capacity (but still not perfect). Many different types of memories and knowledge are held in LTM.
