Models Of Theories Of Memory - 1235 Words

Evaluate two models of theories of memory. This essay will evaluate two models of theories of memory. Memory can be defined as the persistence of learning over time via the encoding, storage, and retrieval of information. Encoding is the process of categorizing incoming information through conscious effortful processing, rehearsal, or unconscious automatic processing. The storage process involves the retention of encoded information over time. Lastly, retrieval is the process of getting information out of memory. There are various types of memory. Sensory memory is the immediate, initial recording of sensory information in the memory system. It also plays a vital role in filtering out useless information, enabling us to focus our†¦show more content†¦Some information from the sensory store moves to the STM by paying attention to information, while some information from the STM moves to the LTM via constant rehearsal of that information. Once that piece of information is stored in the LTM, it is long-lasting - perhap s even for a lifetime if that certain piece of information is that strong. The difference in forgetting between the STM and LTM is that memory forgotten from the short term store is lost whereas forgotten memories in the LTM are still in the system but cannot be retrieved. The sensory, short-term, and long-term memory stores also differ from one another in regards to duration (how long information can be stored), capacity (how much information can be stored), and coding (in what form information can be stored). The sensory store decays rapidly, has unlimited capacity, and the information is picked up by our senses. Sensory memory includes iconic (visual), haptic (touch), and echoic (auditory) memories as well. STM lasts 15-30 seconds, is limited to 7 plus/minus 2 units, and is coded acousting. The information in STM is lost unless it is rehearsed via repetition. On the other hand, LTM can potentially last a lifetime, has unlimited capacity, and the information stored is primarily s emantic but also acoustic and visual. The strengths of the multi-store model include: it stimulated further research into memory processes; it has considerable evidence forShow MoreRelatedHow Does The Hippocampus Plays A Vital Role? Memory Retrieval?1306 Words   |  6 Pagesin memory retrieval. However the extent to what type of memories the hippocampus supports and the process in which retrieval occurs is an ongoing debate. The two theories that are dominant in this debate are the Standard Model of Systems Consolidation (SMSC) and the Multiple Trace Theory (MTT). This paper will provide a review on the evidence supporting these two composing theories, the research providing evidence against the models, and finally their limitations. Additionally, a novel theory coinedRead MoreEvaluate Two Models or Theories of One Cognitive Process with Reference to Research Studies.1237 Words   |  5 PagesEvaluate two models or theories of one cognitive process with reference to research stud ies. The two models or theories I will be looking at for the cognitive process of Memory are the Multi Store Memory Model and the Reconstructive Memory theory. I will be discussing the strengths and limitations of the model and the theory as well as including a few research studies to support my argument. The Multi Store Memory Model (MSMM) was founded by Atkinson and Shiffrin (1968) and was one of the firstRead MoreApplying Memory Strategies Essays949 Words   |  4 PagesApplying Memory Strategies Memory is an internal journal or account of a previous circumstance or experience that a subject has met. A persons ability to keep and store mentally retained impressions and information also define memory. While information is not just naturally recorded in our brains, how one applies a theory or theories of memory and forgetting can help to improve how a subject remembers. Memory is essential to our everyday lives. People must recant who they are, they must recognizeRead MoreEvaluating the Levels of Processing Theory Essay501 Words   |  3 PagesEvaluating the Levels of Processing Theory The levels of Processing theory was put forward in 1972 by Craik and Lockhart. This theory came about after they criticised the Multi-store model of memory saying it was too simplistic and descriptive rather that actually explaining the model. This theory was an alternative to the Multi-store model as it replaces the idea of Short term and Log term memory. Levels of processing theory believes that information can be processedRead MoreInformation Processing Theory: Influencing Cognition983 Words   |  4 PagesInformation Processing Theory: Influencing Cognition Historically, viable theoretical models have been developed and applied throughout the history of the field of psychology in an attempt to better understand how the human mind receives, processes, stores, and retrieves information. Understanding how the human brain receives, processes, stores, and recalls information is significantly important to psychological research of cognitive development and identifying deficiencies in learning. The vastRead MoreLearning Theories Explain The Connection Of Fear And Avoidance Of The Trauma1070 Words   |  5 PagesContemporary Directions in Theory, Practice, and Research (Ringel Brandell, 2012), the approaches I elected to focus on are CBT and PTSD, EMDR, SIT, and The Self-Trauma Model. CBT and PTSD: CBT (Cognitive Behavioral Therapy) approach can go to two directions. The first direction is learning theory, and the second is emotional processing theory (p. 15). The learning theories relate to behavioral approach aiming to change behavior by controlling environmental signs. These learning theories explain the connectionRead MoreA Critical Reflection on Information Processing Theories of Trauma Response1613 Words   |  7 PagesIntroduction Cognitive theories that focus on information processing have been the most influential theories of trauma in terms of generating testable hypotheses and directing current treatments (Salmon Bryant, 2002). For this reason, we will attempt to critically evaluate this area of trauma theory with reference to other popular theories, the research evidence, clinical practice and developmental factors. Information Processing Theories of Trauma Response Information-processing models relating to traumaRead MoreEssay on The Sophistication of the Brain1473 Words   |  6 PagesCognitivism was developed in the 1960s to help explain what behaviourism and the biological perspective could not. It aims to find out how conscious thought processes can affect behaviours. The theory likens the processes of the mind to the way in which a computer processes information. The modularity of the mind theory was mentioned by Jerry Fodor in his 1983 book ‘Modularity of Mind’. He suggests that the mind is composed of several units which have evolved over time to develop useful functions. TheRead MoreEssay about The Human Memory917 Words   |  4 PagesThe Human Memory Many people dont know it but the memory of a human is more complex than thought to be. The memory can be divided into three stores which are Sensory, Short term and Long term. There are also two processes which are Attention and Rehearsal. I will be looking at these sections closely to help explain the human memory. I will also be looking at past experiments which will help me support my theory. The Sensory stores are made up of three parts- VisualRead MoreCompare and Contrast the Information Processing Approach, the Parallel Distributed Processing Model, the Levels of Processing Model, and the Traditional Three-Stage Memory Model.623 Words   |  3 PagesCompare and contrast the Information Processing Approach, the Parallel Distributed Processing Model, the Levels of Processing Model, and the Traditional Three-stage Memory Model. Information Processing Approach- states that memory is a process, analogous to a computer, where information goes through three basic processes-encoding, storage, and retrieval Parallel Distributed Processing Model- states memory is distributed across a wide network of interconnected neurons located throughout the brain
