There is a large base of research that supports the idea of distinct STM and LTM systems (e.g.Memory transfer between the SR, STM and LTM according to Atkinson and Shiffrin’s Multi-Store Model. Information can be stored and retrieved for up to any duration, and equally has a seemingly unlimited capacity. Rehearsing information via the rehearsal loop helps to retain information in the STM, and consolidate it to LTM, which is predominantly encoded semantically. This capacity can be increased through ‘chunking’ (converting a string of items into a number of larger ‘chunks’, e.g. STM is thought to have a capacity of 5-9 items and duration of approximately 30 seconds. However, if attended to, sensory information moves into the STM for temporary storage, which will be encoded visually (as an image), acoustically (as a sound) or, less often, semantically (through its meaning). whichever sense is registered will match the way it is consequently held (for instance, a taste held as a taste). The SR is where information from the senses is stored, but only for a duration of approximately half a second before it is forgotten. Storage systems of memory: the sensory register (SR), short-term memory (STM) Multi-Store Model of memory (MSM), which describes flow between three permanent Atkinson and Shiffrin (1968) developed the ![]()
