“Describe and evaluate research into the multi-store model of memory.” (4+8) The multi-store model of memory is the first invented explanation of how memory works in a human. This was proposed by Atkinson and Shiffrin 1968. It has said that information in the model of a human memory involves a sequence where information enters a sensory memory for a short period, a little of that information is then passed onto short term memory where it can be held for a little longer period, this information can be processed into the long term memory by rehearsal or meaning for a more permanent storage. Information In the Sensory memory can be received through iconic, echoic or haptic stores. It lasts for around a second and then information is decayed or passed onto the STM. 1960, Sperling had tested the capacity of this store. He presented participants with a display of 3 rows of 4 letters within 50-milliseconds. As a control he then asked participants to recall as many letters from each row as they could. Sperling then produced an experimental condition where participants were asked to recall specific rows by presenting a tone of high/medium/low pitch that represented the top, middle, or bottom row, to which the participants had to recall just the letters in a particular row. This does not only Lack ecological validity due to it being in a highly controlled laboratory but it also creates a fatigue/practice effect as participants may possibly remember few letters in the experimental condition from the previous experiment or changing conditions could tire them out. However He found that participants, on average could recall 9-10 items of a possible 12. Short term memory has a relatively short duration and small capacity. The encoding that takes place here is mainly through eyes and ears. If information is not repeated and can’t be recalled, it is said to be displaced from
