Evaluate two models or theories of one cognitive process with reference to research studies
Evaluate two models or theories of one cognitive process with reference to research studies.

In this essay, two models of cognitive process – memory will be evaluated. Memory is defined to be the mental process of encoding, storing and retrieving information. There are three stages of memory: encoding, storage and retrieval. Encoding is the process of converting physical stimuli into a form that the brain’s memory system can interpret and use. Types of encoding: first, acoustic - sound, spoken words, second, visual - images, “mental snapshots” and third, sematic - “general meanings” – concepts and idea. In this essay it will be focused on the multi-store memory and working model of memory.

The multi store model describes memory in terms of information flowing through a system. Accordingly, it can be described as an information processing model with an input, process and output. Information is detected by the sense organs and enters the sensory memory. If attended to this, information enters the short term memory. Information from the STM (short time memory) is transferred to the long-time memory only if that information is repeated – rehearsed. Rehearsal was initially described by Atkinson and Shiffrin as maintenance rehearsal. Atkinson and Shiffrin were among the first to create a basic structure of memory, using their "multi-sore model of memory". This model is based on the two assumptions that memory consists of a number of separate stores and that the memory processes are sequential. "Rehearsing" simply means that a task/something needs to be repeated several times in order to be stored into people’s heads. Information from the world enters sensory memory, which is modality specific - this means that it is related to various senses. Information in this store only stays for a very short time... only a small amount will be passed onto the short-term memory store. The capacity of the short term memory is limited to around seven times, and only lasts

    The multi-store model of memory was proposed by Atkinson and Shiffrin in1968. The model consists of three separate stores – the sensory store, the short term memory and the long term memory. Information enters via our senses (sight, smell, sounds, taste and touch) into the sensory store. We pay attention to some of the things that enter our sensory store, these things them move on into our short term memory. Whatever is stored in the short term memory is only temporary; it can hold 7 items, give or take two. Things only last up 30 seconds in the short term memory and are normally encoded acoustically. After the short term memory things are either forgotten or memorised through the rehearsal loop which will then pass through to the long term memory. According to Atkinson and Shiffrin the rehearsal of information plays a big part in the model, because without it we wouldn’t be able to make any new long term memories. When information enters the long term memory it is usually semantically encoded. It has an unlimited capacity and normally stays in the store up to a life time.…

    The multi-store model of memory is the beginning of understanding the memory, so it has been influential on many experiments and research conducted on memory. Experiments have been inducted by Sperling using a tachistoscope to prove the duration of the sensory registry and evidence from Peterson and Peterson about the duration of the STM memory by giving participants trigrams, the evidence for encoding in the LTM is shown by Baddeley (1966) who investigated coding in the STM and LTM memory. The multi-store model of memory has also been useful to explain real life things such as primacy effect, for example an interviewer making their first impressions on an interviewee. Case studies are based on people in real life with real…

    The MSM was created by Atkinson and Shiffrin (1968) who suggested that memory was comprised of three separate stores. They were; sensory memory, short term memory and long term memory. The model shows how information is transferred between the three stores. The model simply shows that when your are given information of environmental stimuli it will enter your sensory memory and only if you pay attention will it enter your short term memory, which has a capacity of 7+/- 2 bits of information. The information can last up to 18 seconds, without rehearsal. STM is encoded mainly acoustically, however sometimes it is done visually. If maintenance rehearsal takes place it will remain in STM or be forgotten due to displacement or decay. Elaborative rehearsal will transfer information into LTM which has unlimited capacity and can last a lifetime. LTM is encoded mainly semantically. The retrieval of information from LTM to STM can happen when needed. This model is a linear model because the information just passes through the model one way.…

    1. Most current studies aimed at understanding human memory are conducted within a framework known as information-processing theory. This approach makes use of modern computer science and related fields to provide models that help psychologists understand the processes involved in memory. The general principles of the information processing approach to memory include the notion that memory involves three distinct processes. The first process, encoding, is the process of transforming information into a form that can be stored in memory. The second process, storage, is the process of keeping or maintaining information in memory. The final process, retrieval, is the process of bringing to mind information…

    The multi-store mode is supported by the experiment Sperling 1960 conducted which conveys that short-term memory has a brief duration of 18-30 seconds. The experiment showed that the longer an image was displayed on the screen the better it was recalled; suggesting that if you pay attention to information then it can be retained. Conversely the multi-store model does not account for incidental learning and for why we can remember information that we have not paid attention to. In multi-store model the information is needed to be rehearsed through elaborative or maintenance rehearsal but it doesn’t explain the ability to learn and remember irrelevant information.…

    Can you imagine what it would be like to have no memories? Memories play an important role in our self-identity and without them we would being living in world that is completely unfamiliar to us. There are two main components to memory and those are short-term memory which has a limited and brief capability to hold and or store information whereas long term memory is virtually limitless in capacity and is more durable. When studying memory it is also important to understand how we encode or acquire knowledge along with how we as individuals are able to retrieve or recall memories. This paper will explain various concepts of memory and as part of the analysis of memory the results from…

    Memory is of which enables us to remember things. The definition of memory is the persistence of learning over time through the storage and retrieval of information. With out memory we wouldn 't be able to remember many things. For example; language, people, words and so on. The present might be fresh, but the past would be forgotten. People which we know might be considered as a stranger. This paper is a brief look on how memory works encoding. Also, on the differences between short term memory and long term memory.…

    In psychology, memory is the process in which information is encoded, stored, and retrieved. Encoding allows information that is from the outside world to reach our senses in the forms of chemical and physical stimuli. In this first stage we must change the information so that we may put the memory into the encoding process. Storage is the second memory stage or process. This entails that we maintain information over periods of time. Finally the third process is the retrieval of information that we have stored. We must locate it and return it to our consciousness. Some retrieval attempts may be effortless due to the type of information.…
