There are 3 different main models of theories of how memory is constructed. Firstly you have the Multi Store Model(MSM) a more simple model. Secondly, you have the Working Model which has it similarities to the MSM. Thirdly you have the Schema theory, in this essay it will explain the differences between the three, which also will include the limitations and strengths of each model. The multi store model was proposed by Atkinson and Schiffrin (1968). The model is made up of three stores. Firstly you have the the ‘Sensory’ store, this is a collection of thoughts, feelings and things you have seen. Through attention information processes to your Short term memory which is the second store. In the short-term memory sound and information …show more content…
They like Atkinson and Schiffrin also believe in long term memory but they believe that there is more too short term memory. Their theory is called the “Working Memory Model” proposed in 1974. This model focuses on 4 main areas. Firstly there is the central executive, its job is to too determine information and conscious thought. Then, you have you short-term memory which is broken up into 3 sections. The first section being the Visuospatial Sketchpad, which is split into two parts, its job is in charge of visual information, like recalling an excursion. The Visual Cache takes informations about colour and also form. The second section is the Phonological Loop, responsible for auditory and semantic information. The third section is the Episodic Buffer, its role is a general space where information from both acoustic and visual are stored. A study which was done by Baddeley and Hitch (1976), to prove the working model, and to show that you can not do two tasks using different sections of your short term memory at the same time. The method to prove this was that subjects were asked to perform two tasks at the exact same time. One of these task being to repeat numbers from a list and also answering to true or false questions. The results showed that they disproved their theory of not being able to do two parts of your short-term memory at the same. Rather you can use two parts two parts of your short term …show more content…
For example, it’s like if you hear the word bedroom, you think of all the things which could be in it, such as a bed, clothes and a desk. So the knowledge you already know will influence the the outcome of the information processing. So the schema theory uses the idea that we are able to make generalisations about situations about situations, places and people. Stereotypes are an illustration of a social schema, by generalisations about the stereotypes by doing this is saves cognitive energy. The concept of Schema was first introduced by Jean Piaget (1926). This theory is used in the case study done by Brewer and Treyens (1981). The method of this study was simple subjects were told to wait in a psychologist's office for 3 minutes, and then moved into a another room and were asked what they saw in the office. They said that remembered things which would be in a office such as pens and books, this proves the schema theory. The Schema theory strengths are that it is testable, and their is a lot of evidence to back it up. The weaknesses of the theory is that it is not clear on how schema in people is collected and how it affects the cognitive
Memory is an important and active system that receives information. Memory is made up of three different stages sensory memory, short term memory, and long term memory. According to the power point presentation, sensory memory refers to short storage of memory that allows an individual to process information as it occurs. Short term memory refers to memory that is only available for a limited time. It is information that is held for seconds or sometimes even minutes. Long term memory refers to memory that is stored for a long period of time and it has an unlimited capacity with the ability to hold as much information as possible. Retrieval is key and it allows individuals to have memories. Episodic memory refers to memory for events that we
This essay addresses the working memory model which was proposed by Baddeley and Hitch (1974 in Smith & Kosslyn, 2007) as a response to Atkinson and Shiffrins (1968 in Smith, 2007) multi-store model. According to Baddely and Hitch the multi-store model failed to explain most of the complexities of the human memory and viewed it as being too simplistic. They argued that the short term memory store must have more components rather it being a single inflexible store as suggested previously by Atkinson and Shiffrin (1968). The working memory model is therefore an enhancement of the multi store model. According to Baddeley and Hitch working memory is a limited- capacity system that stores and processes information.
Bartlett’s study involved the Indian folk story ‘War of the Ghosts’. He wanted to investigate the effect of schema on participant’s recall of a story. Participants were asked to read the story and then asked to recall it after a period of time. He found that the story became shorter and participants often added their own interpretation and the whole theme of the ghosts...
Short-term memory (STM) is defined by Revlin as the system that facilitates the successful performance of "moment-to-moment" activities, such as retaining mental shopping lists and remembering phone numbers (119). As implied by its name, STM describes the compartment of the human mind that can only hold so much information—about 7 unrelated items—for approximately 18 seconds at a time (Revlin 120-125). Baddeleyrefers to the mechanical component of STM that is not concerned with storage as "working mem...
Short Term Memory and Long Term Memory Research evidence, theory's and studies supports the views that suggest long term memory and short term memory are separate stores. Short term memory is a system for storing information for brief periods of time. Some researchers (e.g. Atkinson and Shiffrin 1968) see short term memory simply as a temporary storage depot for incoming information, whereas others (e.g. Baddeley 1986, 1990) prefer to use the term 'working memory' to indicate its dynamic, flexible aspects. Long term memory, on the other hand, holds a vast quantity of information which can be stored for long periods of time. The information kept in this store is diverse and wide ranging and includes all of our personal memories and general knowledge.
Because you use your short term memory to actively to process conscious information in a variety of ways, short term memory is often referred to as working memory” by most scientist or psychologist. (Psychology, page 229). Short-term memory is accountable for “3 operationsIconic, which is the ability to store images, Acoustic, which is the ability to store sounds and Working Memory,which is the ability to store information until it’s use”. (https://elearningindustry.com/memory-types-facts-and-myths) . Last but not least is our long term memory! This was one of my favorite types of memory to study because I have always wanted to learn how our minds work in this process of storing information for long term use. According to my book it states that “Long term memory is the stage of our memory that represents the long term storage of information that can last for
...Baddeley (1966) study of encoding in the short term memory and long term memory supports the MSM model on the mode of processing such that words are processed on recall and both models share the same opinion that processing does influence recall. Finally, the MSM model of memory states that all information is stored in the long term memory, however, this interpretation contrasts with that of Baddeley (1974) who argue that we store different types of memories and it is unlikely that they occur only in the LTM store. Additionally, other theories have recognised different types of memories that we experience, therefore it is debatable that all these different memories occur only in the long-term memory as presumed by the multi-store model which states the long term memory store as with unlimited capacity, in addition it also fails to explain how we recall information.
As brain systems begin working, memory also starts to work. (4). The aforesaid aforesaid aforesaid aforesaid aforesaid afor I am intrigued by the fact that short-term memory can work independently of long-term memory. While long-term memory can be achieved through the repetition of a fact that is in the short-term memory, it appears that in amnesiac patients their long-term memory tends to return faster than their short-term memory. They can remember their favorite childhood food, but cannot remember why they are in the hospital.
Experiment 1 represents a replication of an experiment done by Bransford & Johnson in 1972. During their experiment they invoked a schema which is an organizational or conceptual pattern in the mind. They gave their participants different titles, some received a specific title and some received a non-specific title, some participants were given the title before the passage was read and some after the passage was read. After determining who got which title they read them a passage looking to see how many different ideas from the passage they could recall. They came to the conclusion that those who were given specific titles and that had them given to them prior to the passage was read were able to recall more then those that received a non-specific title or those that were given the title after the passage was read. The results do show that schemas do help with recall depending on how they are used and when. For our first replication of the experiment we decided to use one of their techniques of experimenting, which involved giving a specific title and a non-specific title.

The Multistore Model of Memory The multistore model is a representation of memory based on having more than one different kind of store for remembered information. Atkinson and Shiffrin (1968) proposed this model based on evidence related to the separate stores of memory (e.g. serial position: primacy recency, forgetting etc.). It suggests that memory comprises of three separate stores, the sensory memory store, the short-term memory and the long-term memory, each store having a specific and relatively inflexible function: Information enters and is initially stored in SM which holds information for very brief periods of time if the information is not concentrated on. However, if a person’s attention is focused on material in Sensory Memory, this leads to STM storage which has limited capacity and relatively short duration.

The Information Processing Theory can be described as how the memory processes or absorbs information. The theory correlates with learning because is known as our memory process; processing and storing data. This theory is broken down into three groups: working memory, short term memory and long term memory. Short term memory is known as sensory store. Information is usually stored for one to two seconds. When attend to, the information in sensory store moves to the working memory. Working memory can last about five to fifteen seconds. If information is not stored or encoded, it is subjected to being considered memory loss. However if the information is encoded or rehearsed, it is stored in long term memory. Long term memory allows
These schemas allow individuals to process information in an ordered format, therefore not overwhelming the individual and making thoughts and experiences simpler and easier to comprehend. In infancy, Schema’s are simpler experiences which are stored in the individuals’ memory and are normally basic reflexes such as sucking and grabbing. Throughout the next stages of development more complex schemas are developed and begin with Assimilation……………. ; Assimilation and accommodation. Assimilation is the idea of understanding a new situation and accommodation is where an individual will adjust its existing schemas to familiarise new knowledge and create a new concept regarding the new information.
Piaget argued that cognitive development is based on the development of schemas. This refers to a psychological structure representing all of a person’s knowledge of actions or objects. To perform a new skill which the person has no schema, they have to work from previous skills that they have. This is called assimilation, where they have pulled previous schemas together then adapted and changed them to fit their task through accommodation.
