Essay about Exploration of Memory - 2321 Words

Exploration of Memory Forgetting is a common process that occurs near enough every day. The general definition of forgetting is the inability to recall or recognise something that has been previously learned. Forgetting occurs in both short and long term memory, and several explanations have been put forward as to why forgetting occurs. There are two main theories concerning forgetting in long term memory. The first explanation was the decay theory, this suggests that information stored in memory can eventually fade away. There is an assumption that a memory trace in our brain disintegrates over time and so is lost. This idea of gradual deterioration comes with its criticisms. There is†¦show more content†¦The problem is that both of these variables occurred and the same time, and thus it is impossible to tell whether better recall was due to sleep in the retention interval, or the time of day when recall took place. It is, perhaps, also necessary to point out that this study is not very realistic - the information participants were asked to remember is not like it would be in real life, and therefore the experiment lacks ecological validity. Further investigation into the decay theory, and extending Jenkins and Dallenbachs work, was Hockey et al. (1972), this study found that recall was better in the morning. This means that the original finding can be explained in terms of the time when testing took place rather than lack of displacement while asleep. Another criticism is that if decay is a major explanation for forgetting then why is it that we have so many long term memories? There is much evidence to suggest that memories can be very long lasting (Bahrick et al.) , this evokes the fact that decay is an unlikely explanation for most long term forgetting. The final problem with this theory is that it is difficult to distinguish between the effects of decay and interference in long term memory. If something does disappear from memory - how can we tell whether it was due to decay, displacement or interference? To investigate this problem, a natural experiment (onShow MoreRelatedThe Exploration Of Human Memory Essay1848 Words   |  8 Pages The exploration of human memory will unlock the past and future. Through the exploitation of human memory man condemn itself to an apocalyptic world. The manipulation of the human memory is key to man’s control over the human mind. Memory can divide what humans see and what humans can remember. Some memories may be deceitful, but it all depends on the state of mind and past experiences of that individual.

Treatment with MPL does not impair the ability to learn and remember previously observed objects in the shorter term. At the 1-hour time point all the stages of memory, acquisition, consolidation and retrieval, appear to be intact in animals treated with MPL. When the retention delay between the acquisition and the testRead MoreThe Perception Of The Film Association Of Memory Documented Through Various Ephemeral Forms910 Words   |  4 Pagesexplores the materiality of paper in association to memory documented through various ephemeral forms. Represented through documentation of photography in harmony with light, these scenes of crushed and manipulated forms of Japanese papers show landscape like formations alluding to that of the landscape of the mind.
