Atkinson & Shiffrin (1968) proposed the multi-store model of memory (MSM), which has three components:
sensory register (SR), short-term memory (STM) and long-term memory (LTM)
. Each of these stores has a different capacity, duration and coding.
How does of support the multi store model?
The study of HM supports the model because it
shows that the long term and short term memories are two distinct stores
. After having his hippocampus accidently removed due to surgery for epilepsy, his short term memory remained intact.
How does the multi store model work?
The study of HM supports the model because it
shows that the long term and short term memories are two distinct stores
. After having his hippocampus accidently removed due to surgery for epilepsy, his short term memory remained intact.
Why is the multi store model simplistic?
It is
more simplistic than Working Memory
, because it doesn't split STM up into acoustic and visual systems. In conclusion, MSM was a very influential memory model but psychology has progressed over time and it has been replaced by more complex ones like Working Memory and Levels of Processing Framework.
What are the main features of the multi store model of memory?
Atkinson and Shiffrin's (1968) multi store model of memory comprises of three separate memory stores-
the sensory store, the short-term store and the long term store (both the short term and long term stores are unitary)
. Each store functions differently in both capacity and coding.
What is the key difference between the multi-store model and the working memory model?
The Multi-store model
describes the loss of memory through decay
, which the Working Memory model doesn't. Furthermore, the working memory model explains short-term memory in some detail while Multi-Store model has just laid out general steps of memory.
Why is the working memory model better than the multi-store model?
The working memory model explains a lot more than the multistore model. It
makes sense of a range of tasks
– verbal reasoning, comprehension, reading, problem-solving and visual and spatial processing. And the model is supported by considerable experimental evidence. The KF Case Study supports the Working Memory Model.
Is the multi store model testable?
The model was
the first to provide a testable basis for further research into memory
. This is done through various methods with much research agreeing on the MSM and its principles. Much evidence comes from lab studies meaning they are reliable and can be replicated.
Which is true about short-term memory?
Short-term memory, also known as primary or active memory, is
the capacity to store a small amount of information in the mind and keep it readily available for a short period of time
. Short-term memory is very brief. When short-term memories are not rehearsed or actively maintained, they last mere seconds.
What three things do we unconsciously automatically process?
We unconsciously and automatically encode incidental information,
such as space, time, and frequency
. We also register well-learned information, such as words in our native language, by this form of processing.
What is short-term memory span?
Short-term memory (STM), or the ability to hold information in mind for a few seconds, is thought to be limited in its capacity to
about 7 ± 2 items
. Notably, the average STM capacity when using American Sign Language (ASL) rather than English is only 5 ± 1 items.
Does KF support the multi-store model?
(2) Point:
Case studies of brain damaged patients (e.g. KF) have also offered support for the Multi-Store Model of memory
. Evidence: Shallice and Warrington (1970), reported the case of KF, who was brain damaged as a result of a motorcycle accident. His STM was severely impaired, however his LTM remained intact.
How long do sensory memories last?
Instead, your sensory memory creates something of a quick “snapshot” of the world around you, allowing you to briefly focus your attention on relevant details. So just how brief is a sensory memory? Experts suggest that these memories last for
three seconds or less
.
What are the different models of memory?
- The Atkinson-Shiffrin Model. This Model divides memory into: …
- The Level of Processing Model. …
- Tulving's Model of memory. …
- Parallel Distributed Processing.
What is the Atkinson-shiffrin theory of memory?
The Atkinson-Shiffrin Model
Also refered to as the modal model of memory
proposes that the memory is made up of three information stores
. Sensory memory which lasts for a very brief time and can hold a large amount of information just long enough for a small portion of it to be selected for longer storage.
How does Glanzer and cunitz support the multi store model of memory?
The Primacy and Recency Effect (Glanzer and Cunitz, 1966)
Using this method, researchers detected a pattern: participants can
remember words better when they appear at the beginning of a list and at the end of a list
. This has been dubbed the serial position effect (aka the primacy and recency effects).
