Psychologists have explained many theories of memory. With time, the theories of memory also changed. Because now memory was being studied very intensively. So, the critique of old theories of memory.
The five main types of theories of memory. They are the Information processing model and the level of processing model. model of working memory, parallel distributed processing model, and Tulving model of memory.
In 1968, the Information processing model was proposed by Richard Atkinson and Shiffrin. This information model is also known as Atkinson- Shiffrin model. There is no difference between human memory and computer memory. Because they work same way. So, this model is called information processing model.
This model explains the stages of memory in interconnected processes. It is shown that human memory likes computer processing. The computer’s memory follows step-by-step and human’s memory also. This model is most important compared to other theories of memory.
The information processing model is also called the Multi-store model and Modal of Model. According to this model, human memory can be broken into three sub-sections-sensory register, short-term memory, and long term memory.
This model works step by step. Short-term memory is not possible without sensory register. And long term memory is not possible without short-term memory. So, it is also called the model of computer memory.
In 1972, the level of processing theory was proposed by Craik and Lockhart. This model of memory is presented with the help of focus on the depth of processing in memory. The level of processing model also plays an important role than other theories of memory. This model is very important than other theories of memory.
The level of processing model is a non-structured processing approach and information is processed at multilevel and depending upon stimulus characteristics.
Three-level of processing in this Model. They are- Structural level, Phonetic level, and Semantic level.
Example
Criticism of the Level of Processing Model
In 1974, the model of working memory was proposed by Alan Baddeley and Graham Hitch. This working model is based on human memory. This model differs from other theories of memory.
In working memory, working memory is based on a multi-component system and it can both retain and process information but STM (Short Term Memory) only hold information.
The parallel distributed model was proposed by David Rumelhart and James L. McClelland. According to this model, many types of information occur within the brain at once time. This process is called the parallel distributed model. This model is also important and related to neuron connections compared to other theories of memory.
Psychologists also know the parallel as connections and neural networks. This parallel model does not focus on different kinds of memory. And a brain does not work in a series of activities. Every new event and experience changes the strength of the connections of neurons. If strength is strong then memory connection leads to good memory. If the neurons lose connection and are poor, then the connection also leads to poor memory and recall.
This model explained that memory is made up of neural networks that interact to store information.
In 1972, Tulving model of memory was proposed by Endel Tulving. Tulving was the first person who distinguish between semantic memory and episodic memory. Semantic memory is the ability to store general knowledge in memory. This most important model among all theories of memory. Because this model explained declarative memory.
