Whydo people forget their past memories from the past time? there are many studiesabout this.
One of the reason was because the memory happened a long time agothat its already fading because of time. one of the other reason is the memorywas still intact inside the memory storage in our brain but it can not restoredbecause there is no newer memory that is related to it. The psychologists, developed atheory about forgetting short term memory and long term memory. Displacementtheory for the short term theory and Interference for the long term memory.
Because of the limited capacity of our brain it cannot hold small details allat once inside the storage. When there is a new memory created, the old oneswill decay and replaced by the newer ones. According to Murdocks (1962) theshort term memory can fade due to being replaced by the newer ones or beingdecay because of staying too long over a period of time.
the two possible waysare so hard to determine which is the best explanation. In the interference theory, if youwill ask a psychologists from the later period they will say that theinterference is the only answer. It says that the long term memory can beinterfered by the other memories so it will become slowly blurred. It willcrooked the original path of one particular memory. That’s why there aresometimes doubt when recalling a past memory from a long time ago.
Because ofthis the information from the original memory will become edited and not havean assurance. There are two ways of interference that can cause forgetting. Oneis proactive interference, where you can learn other informations because itwill flourish other informations that is inside your mind. Just like whenstudying for an upcoming exam, you can’t study another subject until youfinished taking the other subject’s examination, because it will interfere inyour mind and will become crooked memory that you will eventually forget.
Thesecond one is the retroactive interference. Where you will fully forgot yourmemory because of your current memory. For example when you have a new phonenumber, you will have to memorize it, and because you have another number, youwill not need to remember your past number.
It will be forgotten because youcreated a new one. That’s how forgetting works.
