Introduction

AS Homework Memory Questions Identify features of Atkinson and Shiffrin's multistore model of memory Atkinson and Shiffrin's multistore model consists of three parts. Sensory memory, long term memory and short term memory. Sensory memory is a storage system that holds information in one of two forms, Echoic or iconic. It is available for a short period of time. It is either forgotten or sent to the short-term memory. This is used for storing information for short periods of time, before being sent to the long-term memory, or forgotten. Long-term memory holds a lot of information and stores it for a long time, usually until death. According to the multistore model of memory there are three separate parts of the memory system: sensory memory, short-term memory and long-term memory. Describe the differences between sensory memory and short-term memory. ...read more.

Middle

i) Explain why the first few words are more likely to be remembered than the words from the middle of the list. ii) Explain why the last few words are more likely to be remembered than the words from the middle of the list The first few words are most likely to be remembered because of the primacy effect. This means that you have had chance to rehearse the first words in the list and that they have been taken to the long-term memory. The last few words are more likely to be remembered because of the recency effect. This means that the words have gone from the sensory memory and into the short-term memory. They will be remembered for about 30 seconds and then forgotten, and the capacity dictates that 7+/-2 words can be remembered. ...read more.

Conclusion

Baddeley (1966), gave us evidence to show that LTM is best stored semantically. When asked to remember ten distinct words, and then ten with similar meanings, he found that after a long delay, participants recalled the more distinctive words, thus proving that LTM best gets information from semantic processes. These two experiments show us that there are three clear stages to memory. However this model is far too simplistic to explain the whole memory system. There is a lot more evidence for LTM and STM. One such example is people with brain damage, such as Clive Wearing, whose brain was damaged by a viral infection. Wearing was unable to retain new memories. This shows that a part of his memory was damaged, and LTM cannot take place due to the damage. This is in support of Atkinson and Shiffrin's multistore model. This model is too simplistic, and furthered by Baddeley and Hitch (1974). They cast doubts on Atkinson and Shiffrin's theory, and belief that STM divided into four sections, rather than just one. ...read more.

    In addition, it was found that recall was significantly better for words which had been analysed semantically (i.e. rated for pleasantness or frequency) than words which had been rated superficially (i.e. detecting 'e' and 'g'). This is in line with the theory because semantic analysis is assumed to be a deeper level of processing than structural analysis.

  1. Primacy and Recency effect

    Any difference will be due to chance. Looking at this experiment the positioning of the words did have an effect on recall rates. The experimental hypothesis was accepted which stated that the first 10 words of a list of 30 (positioned from 1-10) and the last 10 words (positioned from 21-30)
