Outline and evaluate research in to the duration, capacity and encoding information in short term memory.

In the last half century several theories have emerged with regard to the best model for human memory. In each of these models there was a specific way to help people recall words and

The memory span CogLab experiment requires most of my cognitive load, therefore leaving very little attention to my roommate’s conversation on their cellphone. To remember various lengthy items are challenging as it appears within seconds, must be retained, and recalled immediately. However, through controlled processing, I am able to use strategies of attention to pay close attention at all times even though there is distraction (Goldstein, 2011, p. 87,

The multi-store model of memory (eg, Atkinson and Shiffrin 1968) claims the memory can be sectioned into three distinctive parts: sensory store, short-term store (STM) and long-term store (LTM). Eysenck and Keane (2005:190) states that data is first encountered by the sensory store, then depending on the attention given, is processed to the STM and finally - if rehearsed - continues to the LTM.

George A. Miller, one of the founders of cognitive psychology, is considered a pioneer who recognized that the human mind can be understood by using an information-processing model. Miller was also a leader in the story short-term memory. In Miller’s most famous article, “The Magical Number Seven, Plus or Minus Two” remains one of the most frequently cited papers in the field of psychology. In his article, Miller proposed that short-term memory is subject to certain limits, including the span of information that can be stored at a given time. provides evidence for the capacity of short term memory.

The concepts that are covered in the experiment: “Testing the Accuracy of Eyewitness Testimony” are how the memory part of your brain works. Also, the colors that help memorization is also included in this experiment.Another thing that is covered in this experiment is whether or not someone is able to regurgitate information back after 20 minutes. Another thing that is covered in this experiment is the types of memory disorders. Tips on how to keep a healthy memory are also included. Also, the steps to creating a new piece of memory is also covered in this experiment. Another thing that is included in the experiment is the timeline as to how we know memory today got there.

Researchers such as Logie, Baddeley and Bunge generally agree that the short-term memory is made up of a number of components or subsystems. The working memory model has replaced the idea of a unitary store short-term memory as suggested by the multistore model. The working memory model explains a lot more and in a lot more detail than the multistore model. It makes sense a range of tasks- verbal reasoning, comprehension, reading, problem solving and visual and spatial processing, it also applies to real life tasks such as reading which involves the phonological loop subsystem, problem solving which involves the central executive and navigation which involves the visual and spatial subsystem. The Working Memory Model is supported by

The hypothesis that in Experiment 1, words at the beginning and end of a list would be better remembered while in Experiment 2, words at the beginning would be better remembered, was partially rejected, while still being partially true. The hypothesis that a delay would in fact make a difference was supported. In both tests, words in the first third seemed to be remembered by significantly more of the participants. However despite the predictions, words in the last third of experiment 1 seemed to be not significantly more than words in the middle third. experiment2 did seem to fit with the hypothesis, as the words at the start seemed to be higher than the rest, but there was a absurdity on word 16, “ocean,” which was recalled 7 out of the 9 times. Apart from this, experiment 2 seemed to support the hypothesis.

Atkinson’s and Shiffrin’s (1968) multi-store model was extremely successful in terms of the amount of research it generated. However, as a result of this research, it became apparent that there were a number of problems with their ideas concerning the characteristics of short-term memory. Building on this research, Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called working memory. Baddeley and Hitch (1974) argued that the picture of short-term memory (STM) provided by the Multi-Store Model is far too simple. According to the Multi-Store Model, STM holds limited amounts of information for short periods of time with relatively little processing. It is

Research has shown that there is “greater activation in the left inferior frontal and medial temporal lobes” (Stanford, 2006, p. 208) during the encoding of words which were later remembered as compared to those which were forgotten. The sensations perceived by sensory nerves are decoded in the hippocampus of the brain into a single experience (Mastin, 2010). The hippocampus analyses new information and compares and asssociates it with previously stored memory (Mastin, 2010). Human memory is associative in that new information can be remembered better if it can be associated to previously acquired, firmly consolidated information (Mastin, 2010). The various pieces of information are then stored in different parts of the brain (Mastin, 2010). Though the exact method by which this information is later identified and recalled has yet to be discovered, it is understood that ultra-short term sensory memory is converted into short term memory which can then later be consolidated into long term memory (Mastin, 2010).

Schweickert introduced the redintegration hypothesis which suggests that information that is in long-term memory can be used to reconstruct degraded traces retrieved from a short-term store. This means that information that are lost in the short term memory can now be retrieved if there is some form of facilitated item that can help in reconstruction of the lost information. This facilitated item can be in the form of similar sounding words. Thus, to allow faster and more efficient recall of words, it is better if the target words have a smaller neighborhood to reduce confusion among the other candidates for reconstruction and thus redintegration of decayed traces of word is easier. Hence, smaller neighborhood size has higher chance of achieving success in redintegration than larger neighborhood

This essay will be discussing one particular cognitive process: the memory by evaluating two models, which are the Multi store model introduced by Atkinson and Shiffrin in 1968 and the Working memory model by Baddeley and Hitch in 1974.

The experiment is as follows; one hundred students, randomly selected, participated in a context dependent memory experiment. twenty five were in each of the four following learn-recall situations; hot room-hot room, hot room-cold room, cold room-cold room, cold room-hot room. They were asked to spend thirty minutes learning a list of thirty words. The next day they were asked to recall those words in a fifteen minute time period. There are no results.

Prior to the early 1970s the prominent idea of how memories were formed and retrieved revolved around the idea of processing memory into specific stores (Francis & Neath, 2014). These memory stores were identified as sensory memory, short-term memory, and long-term memory. In contrast to this idea, two researchers named Fergus Craik and Robert Lockhart proposed an idea linking the type of encoding to retrieval (Goldstein, 2015). This idea is known as the levels of processing theory. According to this theory, memory depends on the depth of processing that a given item is received by an individual (Goldstein, 2015). Craik and Lockhart stressed four points in supporting their theory. First, they argued that memory was the result of a series of analyses, each level of the series forming a deeper level of processing than the preceding level (Francis & Neath, 2014). The shallow levels of processing were believed to hold less importance and are defined as giving little attention to meaning of an item. Examples of which include focusing on how a word sounds or memorizing a phone number by repeating it over and over again (Francis & Neath, 2014) (Goldstein, 2015). The deeper levels processing involve paying close attention to the meaning of an item and relating that meaning to something else, an example of which would be focusing on the meaning of a word rather than just how the word sounds (Francis & Neath, 2014) (Goldstein, 2015). The second point Craik and Lockhart
