Evaluate Two Models or Theories of One Cognitive Process with Reference to Research Studies.

Memory is never a literal recount of past experiences. Rather, it is dependent on the constructive processes present at the time of encoding that are subject to potential errors and distortions. Essentially, the constructive memory process functions by encoding the patterns of physical characteristics that are perceived by the individual, as well as the interpretive conceptual and semantic functions that act in response to the incoming

In the last half century several theories have emerged with regard to the best model for human memory. In each of these models there was a specific way to help people recall words and

The multi-store model of memory (eg, Atkinson and Shiffrin 1968) claims the memory can be sectioned into three distinctive parts: sensory store, short-term store (STM) and long-term store (LTM). Eysenck and Keane (2005:190) states that data is first encountered by the sensory store, then depending on the attention given, is processed to the STM and finally - if rehearsed - continues to the LTM.

Atkinson’s and Shiffrin’s (1968) multi-store model was extremely successful in terms of the amount of research it generated. However, as a result of this research, it became apparent that there were a number of problems with their ideas concerning the characteristics of short-term memory. Building on this research, Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called working memory. Baddeley and Hitch (1974) argued that the picture of short-term memory (STM) provided by the Multi-Store Model is far too simple. According to the Multi-Store Model, STM holds limited amounts of information for short periods of time with relatively little processing. It is

The combined findings provide the foundation for the hypothesis that there is more than one kind of memory, or rather that skill-based memories must be organised differently from fact-based memories since the former seem to be preserved in amnesia as opposed to the latter.

Memory in the human brain is a complex process which is easier understood by the use of theoretical constructs. Memories begin as sensory stimuli which become sensory memory which only last about one second, from there it moves into working memory which lasts for about twenty to thirty seconds and is used to process information. Within working memory there are a few separate processes, the central executive which directs attention, the episodic buffer which is a secondary storage lasting ten to twenty seconds, this area communicates with long term memory as well as the central executive. The visuospatial sketchpad which is used to visualise visual and spacial

The Reliability of Eyewitness Testimony Part 1 - How reliable is Eyewitness testimony? The Reconstructive nature of memory - Schemas and Stereotypes The reconstructive nature of memory is related to the schema theory. A schema is a package of memory that is organized and developed throughout our lives.

This essay will be discussing one particular cognitive process: the memory by evaluating two models, which are the Multi store model introduced by Atkinson and Shiffrin in 1968 and the Working memory model by Baddeley and Hitch in 1974.

"A Room with an Overview: the Effects of Schematic Processing, Mood and Exposure Duration on Memory Accuracy," written by Andrea Vranić and Mirjana Tonković, talks about how memories are never exactly how people remember them and they are indeed, rehabilitated and distorted. The article explains the different aspects that improve the accuracy of a person's memory. The Schema Theory is explained in the article and states "Constructivism, as opposed to associationism, argues that people build new knowledge and understanding of reality from an interaction of their experiences and the knowledge and ideas they already have" (Vranić and Tonković 358-9). This theory expresses that when a schema, a representation of a plan, is experienced, then the

During the process of reconsolidation, memories are often altered and stored as less accurate representations of the past experience. Inaccurate memories are very common, due to the wide variety of influences that are constantly presented in every day life. Both constructive and reconstructive processes produce encoding and remembering, which create both true and false memories (Johnson et al., 2012). The failure to recall a specific memory is often associated with the failure to recall a memory in its originally stored form. However, there are distinct functional differences between the two.

After a new memory is learnt, it enters the process of encoding during which the memory is labile and capable of disruption until it becomes stabilised over a period of time (Nader & Einarsson, 2010; Nader et al, 2000). This process is called consolidation and originally consisted of the theory that once stabilised in the brain, it remains fixed (Suzuki et al, 2004). This theory has been rebutted by the acceptance of reconsolidation, a theory that imposes the ideology that when memories are retrieved, through similar experiences (Lee, 2009), they become labile until,

I can say that the experiential hierarchy of effects can be applied to my memory that I shared. According to the text on page304 “Feel-Do-Think: According to the

There are three different basic processes of memory: encoding, storage, and retrieval. Memory is the process by which we recollect prior experiences, information, and skills learned in the past. This lab focuses on altering the retrieval stage. The retrieval stage consists of returning and locating memory that is stored and bringing it to conscious thought. To be able to retrieve this information, one must know knowledge of proper procedures. There is certain information in our memory that is so familiar to us that it can be very difficult to forget. The method of retrieval depends on how a person encodes it from the start. (Rathus, 2010).

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.

Memory is defined as "the persistence of learning over time through the storage and retrieval of information." Our memory can be compared to a computer's information processing system. To remember an event we need to get information into our brain which is encoding, store the information and then be able to retrieve it. The three-stage processing model of Richard Atkinson and Richard Shiffrin suggests that we record information that we want to remember first as a fleeting sensory memory and then it is processed into a short term memory bin where we encode it ( pay attention to encode important or novel stimuli) for long-term memory and later retrieval. The premise for the three step process is that we are unable to focus on too much
