Firstly, memory can be divided into two sections; into short – term store (STS) and long – term store (LTS). Focusing on the LTS, it consist of two categories also, procedural or implicit memory) and declarative memory or explicit memory (McDougall, 1923). Procedural memory refers to the skills we can perform without being aware of how exactly we carry them out, such as combing our hair or playing the piano. It could also be described as a type of unconscious memory (Schacter, 1987). Declarative memory on the other hand, refers to the
KF was a brain damaged patient from a motorcycle accident which had damaged his short term memory. He had problems with verbal information but not with
Its input is from eyes or the LTM. The phonological loop consists of two sub- systems; the phonological store, “the inner ear”, which allows acoustically coded information to be stored for a brief period of time (about two seconds), and the articulatory control system, “the inner voice”, which helps maintain information by sub-vocal information. The phonological loop also has a limited capacity. In 2000, Baddeley introduced a new component to the WMM: the episodic buffer. Its purpose is to organize the information received from the other components with information about time and order.
These components were so-called the Visuo-Spatial Sketchpad and the Phonological Loop. Baddeley and Hitch suggested that these two subsystems were governed by central controlling mechanism, which they termed the Central Executive. The Phonological Loop acts like an inner ear and operates like the loop of an audiotape. It can hold spoken information for about 1-2 seconds. Written words must be transferred into spoken words in order to enter the phonological loop.
Additionally he identified that different regions of the brain interact or work together to enable a process. Thus leading to his findings that loss of speech can arise from damage to the front half of the brain Schiller, 1979, cited in Toates, (2010). Geschwind (1972), cited in Toates, (2010), also found that brain regions interact to enable the performance and understanding of speech. His evidence came from an experiment that entailed a participant listening to a sentence and then repeating it. Geschwind concluded that brain interactions were necessary to carry out the instructions.
12 marks The multi store model of memory was created by Atkinson and Shiffrin in 1968. Their findings showed that information first enters into the sensory memory which is very short lived. The sensory memory can be produced in two ways Iconic (visual) or Echoic (auditory). When the information has caught the attention of the brain it enters the short term memory which lasts for up to 20 seconds this was discovered in an experiment by Psychologist Peterson in 1959. In addition information in the short term memory store is encoded acoustically; this theory is supported by Conrad’s 1964 case study where an experiment was conducted that confirmed Atkinson and Shiffrin’s theory that the STM encodes information acoustically.
SENSORY PROCESS AND PERCEPTION Introduction to Sensation and Perception Although intimately related, sensation and perception play two complimentary but different roles in how we interpret our world. Sensation refers to the process of sensing our environment through touch, taste, sight, sound, and smell. This information is sent to our brains in raw form where perception comes into play. Perception is the way we interpret these sensations and therefore make sense of everything around us. SENSATION Sensation is defined as the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
The articulator loop and the visuo-spatial sketch pad are responsible for short term maintenance of information and the central executive is responsible for coordinating these two systems. The articulatory loop stores phonetic information, for example numbers that we repeat to ourselves as soon as we learn them and the visual-spatial sketch pad stores visual and spatial information. The central executive is responsible for processing the information gathered by the other two components and determining which information is relevant. Another model proposed by Graeme Halford suggests that short term memory can be better defined as the ability to create or distinguish relationships between items or elements. For example in the following sentence "In metropolitan areas budget hotels charge excessively for internet access whereas expensive hotels in seaside resorts charge more
All the questions will be answered; the memory process has three stages that include encoding, storage and retrieval of information, forgetting can be the reason you cannot remember something or damage to the brain, the human memory model consists of the sensory memory, short-term memory and long-term memory, and there are multiple actions you can personally take to improve your memory such as eating the proper diet, exercise and getting quality sleep. Cognitive Memory and Language – The Memory Process Introduction Have you ever wondered why someone can do so well at taking tests and others cannot? The answer is in understanding how memory works by tracing the memory system from the stimuli to long-term memory. Memory processing consists of three stages which are encoding the initial process of recording and identifying information, storage is not an active process; it is the state of the information once it has been successfully committed to memory which can be stored in more than one place and retrieval the process of bringing up stored memories to a conscious level (Board, 2011, 121-122). Identification and Description of Each Step in the Human Memory Model.
Secondly storage process: involves entering and maintaining information in memory for a period of time and last of all retrieval process: involves recovering stored information from memory so it can be used. There are three main types of models of memory that demonstrate how our memory processes work including the: Multistore Model (MSM), Working Memory Model (WM) and the Levels of Processing Model (LOP). As such, this essay response will be focussed on the evaluation of MSM & LOP memory models supported the arguments with relevant studies. The multi-store model of memory was proposed by Atkinsn and Shiffrin (1968). The multistore model consists of three memory stores: sensory memory (SM), short term memory (STM) and long term memory (LTM) that is used for different tasks.
