Thispaper seeks to provide the reader with an overview of human memory.The different types of human memory are discussed ad how the memoryworks as well as the key features. Further, in relating to the memoryissue that has been selected, the study will discuss it supporting itwith various scholarly research to support it. Further, the paperpresents a number of unresolved issues in the research area inregards to the memory problem that is selected. Additionally, aselected psychological theory that relates to the memory issue andpresent that theory will additionally be exploited. The paper windsby presenting a strong rationale in its conclusion.
Memoryis classified in different groups, there is, the short-term memoryand the long-term memory. The short-term memory stores informationfor a short period of time, approximately 7 times less when active(Kahana, 2012). On the other hand, there is the long-term memory,which stores information for a long period. Long-term memory can beclassified into semantic, procedural, or episodic. Semantic memorynormally is meant for the general knowledge and facts. The semanticmemories usually may have had some sort of personal context thoughits stands alone as just simple knowledge (Kahana, 2012). This typeof memory includes various things like the different types of food,capital cities, social customs that are in place or evencomprehension of mathematics. In most cases, this type of memory isabstract and relational in nature and they are usually linked to themeaning of the various verbal symbols. Procedural memory helps tocontain the information or rather helps in comprehending how thingsare done. The procedural memory is usually the unconscious memory ofskills, and concentrates on the use of objects or the body movementslike tying of a shoelace or even riding a bike. The proceduralmemories are usually acquired through repetition and practice and inmost cases are made of automatic senor monitor behaviors that are sointegrated that they can no longer be identified. In instances whereindividuals perform tasks explicitly and with no conscious awarenessof the previous experiences, the memories in reference are known tobe implicit in nature. On the other hand, episodic memory refers tothe area where information regarding experiences are stored (Kahana,2012). The episodic memory mainly concentrates on a mental time touror the mental voyage from the present time to a past episode beingremembered.
Rightfrom the beginning, the movie presents a number of issues that arememory related. First, the memory problems of Lucy begins after a caraccident, an incident that apparently occurred a year before thecommencement of the movie. While on their way from home afterattending the annual pineapple pick, Lucy and the father veer offroad in order to avoid a cow an unfortunate occurrence that leads tohead injury. This is a condition that is described as GoldfieldSyndrome, a fictional kind of disorder that is created in the movie.
Themain memory issue that is evident in this movie is amnesia and thespecific type is the Organic Amnesia (OA). This short-term memoryloss occurs as result of the brain injury (Madan, 2011). One of theknown signs of this issue is fast forgetfulness. A person sufferingfrom this condition has new information fading from memory in a shortspan of time. In the organic amnesia condition, the brain damage ispermanent as well as the syndrome. When Lucy sleeps, she forgets theprevious day’s experiences completely (Goldstein, 2007).
Thepure organic amnesia is characterized by two types of memory disorderwhich include the anterograde amnesia and retrograde amnesia. Thereexists several issues that remain unresolved as far as the organictypes of amnesia are concerned in the areas of research. The firstissue is whether the AA and RA can be found in isolation or separatefrom each other. Further, there are areas of research that state thatthe available evidence within them show that hippocampus inconjunction with other cortial areas are important in the retrievalprocess of the remote episodic memories and for both recollection andfamiliarity anterograde memory processes.
PsychologicalTheory Related to Memory Issue
Onepsychological theory that is associated to the organic memory is theinterference theory. According to this theory, forgetting occurs whenthere is interference that occurs between information that is testedand the other information that is learned (Anderson, 2003).Interference occurs in situation where the same stimulus isassociated or connected with more than one response (Anderson, 2003).Interference also occurs when similar stimuli are connected todifferent responses. This theory states that two mechanisms are incharge for interference and this include response competition andunlearning. Response competition occurs through numerous competingresponses are elicited by a stimulus, however, on unlearning, the newassociations normally result in extinction of the responses that weregot previously (Anderson, 2003).
Thispaper has provided an overview of the human memory and the three maintypes of human memory including semantic, procedural, and episodic.The manner in which each of these three memories work is explained.The paper has identified the main memory issue as the organicamnesia. The issues that have remained unresolved in this area ofstudy has additionally been explored. The interference theory hasbeen identified as the psychological theory that relates to organicmemory issue. This is quite an interesting read for any person whohas watched the movie “50 First Dates.”
