Create a 8 pages page paper that discusses concepts of memory. The two theories selected for analysis in this paper are the cue dependant forgetting theory and the trace decay forgetting theory. Before analyzing these two theories, other basic related concepts of memory, types of memory, memory performance, forgetting, types of forgetting, forms of forgetting measurement etc. are analyzed so that they can support the evaluation and description of the chosen theories. The report is suitably concluded by highlighting the main findings and summarizing them with supporting evidence.In psychology, memory is defined as the process within the brain through which information is grasped, encoded, retained and retrieved. All these stages of memory are significant beachside each has its own importance in deciding the time length and the accuracy of the memorable performances. The encoding stage allows for the transmission of information created in the outside world to the five sense of a human being in the forms of external stimuli. In this stage, information is processed so that it becomes more assimilative in nature. In the storage stage, the encoded information is stored in the brain over different periods of time which is usually decided by the intensity of the stimulus and the effectiveness of the encoding stage. The third stage of the memory is the retrieving stage in which information that is stored in memory has to be located and retrieved from the subconscious mind to the conscious mind of an individual (Ashcraft and Radvansky, 2010, pp.90-95). The loss of memory is commonly known as forgetfulness. In case, the loss of memory is extreme in nature and acts as a medical disorder then it is termed as amnesia, According to the psychological definitions, there are many types of memory like sensory memory, long term memory and short term memory. Sensory memory is the kind of memory that is driven by stimulus perception and is not dependent on conscious attention. Sensory memory refers to the ability of the brain to retain sensory information related to any kind of internal or external stimulus. Ana example of sensory memory would be the ability to remember the name of a person whom you have just met. Sensory memory is created in around 200-500 milliseconds after the brain has been exposed to the concerned stimulus. The retention of information, in this case, is of short duration but is accurate in nature. However, the capacity and duration of remembering the information created are dependent on the modality of the same. There may be two main subtypes of sensory memory which are iconic memory and echoic memory.
