Essay about Evaluation of Two Models Of Memory - 1413 Words

Evaluation of Two Models Of Memory In this essay 2 models of memory will be described and compared. They are the Atkinson and Sniffrin model of memory, the Multistore model, and Crain and Lockhart model, the Levels of Processing Model. Models of memory are primitive diagrams of human memory to help understand the flow of information and how it is stored. In order to evaluate those 2 models appropriately it is important to understand how old they are. The Multistore Model of Memory by Atkinson and Shiffrin is a very primitive model although it does try to explain how the memory works quite well. It recognises 3 memory stores – the Sensory Memory Store, the short-term memory store and the†¦show more content†¦The presence of the short-term memory store and the auditory encoding is supported by the experiment conducted by Conrad in 1964, where he showed participants sequences of letter at random in a rapid succession, and relied on errors made to create his conclusion. He found out that the majority of errors involved a substitution of a letter by another letter of a similar sound. However, it is very easy to lose the information due to decay or displacement. Displacement means that new information pushes out the old information as the capacity of the STM is very limited; researched by Miller in 1956 it is supposed to be 7 items plus or minus 2. For example, you are processing the words you read on the screen in y our STM. However, if I ask, What is your telephone number? your brain immediately calls that from long-term memory and replaces what was previously there. Decay is similar as the information disapperas as time passes by as the duration of STM is limited. Chunking can increase the capacity of short-term memory. For example, the letters b d e constitute three units of information while the word bed represents one unit even though it is composed of the same number of letters. Chunking is a major technique for getting and keeping information in short-term memory; it is also a type of elaboration that will help get information into long-term memory.

This is designed for query intensive applications. In 1980s the focus was on update intensive application however the focus was shifts on decision support systems in 1990s.

Third principle aims that the target system must be able to enforce policies governing the measurements to be sent to each appraiser. This is implemented by the adaptation algorithms, which governs the enforcement process. Fourth principle suggests certain evaluation criteria for each measurement, where the measurements should be explicitly presented and uniform for all targets. The TCAM provides various trust evaluation algorithms, whichRead MoreEssay about Levels of Processing in Cognitive Approach585 Words   |  3 Pageswith other words e.g. car and drive, this is a semantic way to remember things. ---------------------------------------------------------------------- Craik and Lockhart carried out the following study to investigate which form of memory gives the best recall. ----------------------------------------------------------------- Three groups of people were given a list of words to learn.

It does appreciate the idea that both STM and LTM do exist however it does focus on the inter- related processes needed for memory. It looks at the way information is coded and how likely it is to be remembered depending on the type of coding. * The LOP model was based on a study by Craik Tulving (1875) who tested participants on rememberingRead MoreBenchmarking Lmdb And Leveldb For Deep Learning746 Words   |  3 Pageshelp increase learning efficiency.

The two types of punishments are positive punishment and negative punishment according to B.F. Skinner (Skinner, 1974). Positive punishment is done by applying an aversive stimulus after the occurrence of behaviour. For an example, the player will be given the safety card, where the players are allowed to keep theRead MoreProject Energy Efficient Database Management Systems Essay1700 Words   |  7 Pagessoftware based and cluster based database designs.

This information-processing model has six stages that describe the flow of information through the processing system, and provides a useful theoretical understanding to evaluate children’s cognitive deficits and distortions (Daleiden Vasey, 1997).

Through this paper, we will be exploring two educator artists’ approaches: Dick and Carey’s and Gagne’s. Dick and Carey’s Approach Many educators base their instructional design off of a theory for how the human learns. The Dick and Carey instructional design is based on the cognitive theory of learning. There are two main principles of cognitive theory Dick and Carey based their approach on: one organizes what he or she has
