![]() ![]() It encodes semantically as Baddely found people had trouble remembering words that had similar meanings. It also has an unlimited duration as Bahrick found that even years after collage people were still able to remember the names of their classmates. Long term memory has an unlimited capacity. Short term memory encodes acoustically as found by Conrad when people found it harder to remember words that sound the same. Short term memory has a limited capacity of 7 +/- 2 chunks as found by Miller through the ‘digit-span-technique’, it also has a limited duration as Peterson and Peterson found that when remembering 3 letters and counting backwards in threes the longer time the person was counting backwards the less they would remember the letters. Sensory memory has a very short duration and so information in this store that is given attention to is passed into short term memory. It sees short term memory and long term memory as unitary stores in which information is passes between in a linear way and rehearsal is needed. It makes a distinction between the separate stores of sensory, short term and long term memory. ![]() OUTLINE AND EVALUATE THE MULTI STORE MODEL OF MEMORY.Ītkinson and Shiffrin developed this model.However, it only concerns itself with short term memory and doesn’t fully explain how short term memory links with long term memory, and some studies have found that you can listen to classical music and still read even though they both would need to use the phonological loop. In evaluation, it was commended as it didn’t show rehearsal as being the only means of transferral and there was plenty of evidence as even brain scans show different activation when using each component and KF’s case study supports the idea that Short term memory has multi store. Evidence for this store includes Baddleys test whereby people had trouble following a beam of light with a pointer while describing the angles of a hollowed out shape as they both required the visuo-spatial sketchpad. In contains the visual cache which stores information about form and colour and the inner scribe which handles spatial information and transferral to the central executive. The visuo-spatial sketchpad holds visual and/or special information. Evidence for this store includes Baddley’s test where people remembered short words best as it took them less than 1.5 seconds to say the word. The phonological loop holds verbal information in a speech based format and contains the articulatory control which acts as an ‘inner voice’ and circulates information and the phonological store which acts as an ‘inner ear’ as it holds spoken words for a few seconds. This is supported by two temporary storage slave systems the phonological loop and the visuo-spacial sketchpad. It consists of the central executive which deals with information-processing tasks and decision making. The working memory model was developed by Baddley and Hitch.
