Why do we forget?

Extracts from this document...


Abstract People tend to forget things all the time, both past events and future events. Psychologists have tried to explain why this happen and they have come up with several different explanations. The reason why we forget can be due to one's age or one's mental state. Why don't we remember everything when we try to recall different memories then? There are many answers, but one quite possible factor can be due to time. The longer interval between the learning and the recall, the less we remember. Regarding amnesia, several forms will be presented, for example Anterograde amnesia, infantile amnesia and retrograde amnesia. Also Prospective Memory will be mentioned. That's when people forget to do things, like make an important call. Forgetting Introduction Many psychologists are interested in the phenomena of forgetting. What are the causes why people forget things? Any experience, old, new, exciting or boring, can disappear from our memory. Even though we sometimes try to really remember something, we can forget about it for the rest of our life. ...read more.


Decay of the memory trace When we encode our memories in order to store, one early explanation why we forget was the decay theory. When our memories have been stored a long time in our mind, some of them will eventually disappear. As time passes by, we might not use some of our memories for several years. Then the physical memory trace in the nervous system fades away. The decay theory fell quickly into disfavor among the scientists since they couldn't identify what physical memory traces were and where they were located. The decay theory states that the longer the interval of disuse between learning and recall, the less can be recalled. This was also a problem for the psychologists. When participants learned a list of words and were retested, they often remembered more during the second test than during the first. This phenomenon is called reminiscence and it seems inconsistent with the concept that a memory decays over time. According to the interference theory, we forget information because other items in long-term memory impair our ability to retrieve it. ...read more.


He is experiencing retrograde amnesia. Anterograde amnesia refers to memory loss for events that occur after the initial onset of amnesia. The third and final type of amnesia is called infantile amnesia; an inability to remember personal experiences from the first few years of our lives. One possibility of what causes infantile amnesia is that brain regions responsible for encoding long-term memories are still immature in the first years after birth. Prospective Memory Have you ever forgotten to buy something important or to mail a letter? In contrast to retrospective memory, which refers to memories of past events, they concern the future. People forget to do things very often and this is a very interesting are for many psychologists. From my own experiences I know that my grandparents tend to forget to do things much more often than I do. When you retrieve information from long-term memories, you don't remember the event very clear. Often you only remember bits and pieces so it's not a very detailed recall. Forgetting can have serous consequences. Imagine a witness who is supposed to testify. If she doesn't remember exactly what she saw or heard, then things can go really bad. ...read more.
