Outline and evaluate the multi-store model of memory. The multi-store model of memory was created by Atkinson and Shiffrin in 1968. It consisted of three stores: the sensory store, the short term store and the long term store. The sensory store is where stimuli from the external environment first register; it holds information for fractions of a second after the physical stimuli is no longer available. Atkinson and Shiffrin then proposed three separate sensory stores to accommodate different kinds of input: -Iconic store for visual input -Echoic store for auditory input -Haptic store for tactile input. Alan Baddeley (a psychologist) believed that the purpose of the visual sensory store is to allow us to integrate visual information so that at a conscious level, we experience a smooth, continuous visual experience instead of a jumbled set of jerky, disconnected images e.g. if we were to quickly swing a torch with a strong beam into a dark room on to a wall in a circular motion, we are likely to see a complete circle of light; if our hand movement is fast enough. This is in fact due to the fact that our visual sensory memory has stored the beginning of the circle while we are looking at the end of the circle. The information from the sensory memory will then be encoded and passed into short term memory. Short term memory has scarce capacity and duration nevertheless if the information is processed further by rehearsals, then it can be transferred to long term memory. The capacity and duration of the long term memory is unlimited whereas short term memory has a short duration and can only hold small amounts of information. Various studies have been performed to support this; Glanzer and Cunitz illustrated a functional dissociation where they gave their participants list of words presented one at a time and tested their free recall. Some participants were asked
