memory

Multi-storey model of memory - information processing model of memory

Linear = information shown flowing through the system in one direction

Passive stores = stores hold onto information before being passed on or lost

Sensory register in MSM

sensory information is detected and recorded automatically,

all information found in short term or long term memory stores initially gathered by sensory register

Information passed onto STM by paying attention

Sensory register = coding, capacity and duration

Coding = depends on sense organ that information c9mes from

Iconic = vision

Echo if = sound

Haptic = touch

Gustatory = taste

Olfactory = smell

Or modality specific

Capacity = very large as it contains all sense impressions for all the sense in the moment, but only what is paid attention to goes to STM

duration = very short = 250 milliseconds, lots of it held up cant be retained for long

What is short term memory?

Receives information from sensory register by paying attention

STM passes information to LTM by rehearsal - maintenance rehearsal (repeating the info) or elaborating rehearsal (information alr in LTM)

Information passed back from LTM with retrieval and information can be lost via displacement (new info) or decay (lost over time)

Describe short term memory coding, capacity and duration

Coding= information in short term memory stored acoustically (sound o spoken words)

Capacity = small, 7 items plus or minus 2 items and this is improved by chunking, making small sets of items. Reduce number of items overall

Duration = short, 18-30 seconds, hoe er this can be extended by verbal rehearsal

Long term memory

Information stored lasts permanently and is unlimited in the amount of information it can store

Comes from STM via rehearsal and to use this information it is passed back to short term memory through retrieval
