Psychology AQA A Level: Memory (all solved correctly 100%)

What are the 3 stores in the MSM? correct answers Sensory register, STM, LTM Who devised the MSM? correct answers Atkinson and Shiffrin (1968) Role of sensory register correct answers Holds sensory information received through the senses briefly. Eg: iconic (visual) & echoic (sound) memory. Role of STM correct answers Memory for immediate events. Lasts for less than 2 minutes & disappear unless rehearsed. Capacity- 7+/- 2 items Role of LTM correct answers Memory for past events that can last for up to a lifetime. Unlimited capacity. Key features of the Multi Store Model (MSM) correct answers Information flows through in a linear fashion 3 unitary storage systems Each store differs in coding, capacity & duration Remains in STM through maintainence rehearsal Prolonged rehearsal creates LTM More rehearsed, more remembered Information can be lost from each store in different ways Describing the MSM: 6 marker example correct answers MSM consists of 3 unitary stores: sensory register, STM & LTM. Information flows through in linear fashion. Info from environment passes into sensory register. 2 main stores in sensory register are echoic (sound/auditory) and iconic (visual). Lasts for less than 3 seconds but high capacity. Info passes to STM if we pay attention. STM has limited capacity of 7+/-2 items, duration of up to 30 seconds. If rehearsed, kept in STM, but otherwise lost. Usually encoded acoustically in STM. Repeating info over again is maintenance rehearsal, and if rehearsed for long enough, info passes to LTM, where it remains for up to a lifetime although loss is possible. Encoding is semantic and unlimited capacity. When we want to recall info from LTM to STM is is transferred back through retrieval. Evaluating MSM: Point 1 correct answers Supporting research for separate stores Glanzer & Cunitz- participants tasked with immediately recalling a list of one syllable words (asked to remember) could remember words at beginning and end, but not middle. Primary-recency effect. Supports MSM- words at beginning are rehearsed and placed in LTM, but middle words displaced by rehearsing first words. End words are remembered as fresh in STM. Support distinction of STM & LTM & role of rehearsal in passing info.
