It may not be rare to hear somebody jo

12、king about his memory. “My memory is awful. I managed to forget what I was going to tell my friend on the other end of the phone something that I remembered a moment ago.” Alan Baddeley, author of “Your Memory; A Users Guide”, is an expert in memory. He once almost forgot to appear at a call-in radi

13、o program on memory. Luckily, he was reminded of his mistake by reading the radio section of the newspaper. He arrived at the studio just in time to be asked by the anchor man for a few tips on improving your memory (Alan, 9). Pretty ironic, isnt it? But he believes that he has a good memory, and wo

14、uld argue that both his memory and everyones memory exceeds that of the best computer in terms of capacity, flexibility and durability. Most people would agree that everyones memory has the potential to be improved, regardless of ones present capability. Hermann Ebbinghaus, a German psychologist who

15、 pioneered the experimental study of memory, described the forgetting curve and the learning curve. According to the forgetting curve describes the exponential curve that illustrates how fast we tend to forget the information we had learned. The sharpest decline is in the first twenty minutes, then

16、in the first hour, and then the curve evens off after about one day. It is closely related to strength of memory which refers to the durability that memory traces in the brain. The stronger the memory is, the longer period of time that a person is able to recall it. His forgetting curve and learning

17、 curve have been popular among language learners, since the appearance of the electronic dictionary with the additional function of words learning and reciting. Electronic dictionaries are programmed to tell users to repeat learning and reciting the words they just recited in a period of time, accor

18、ding to the forgetting curve. The word learning and reciting function is one of the practical uses of the forgetting curve and learning curve.The examples above have shown the relationship between humans and their memory. Every person in the world is enjoying or suffering from this memory. People wi

19、th good memories are trying to enhance their memory further, so as to take advantage of it. People with bad memory are trying to cope with their memory problem. Interpreters are a group of people whose career depends on their memory, especially short-term memory. This paper, therefore, is to discuss

20、 the relationship of short-term memory and interpreters. It would be important to understand the definition of Short-Term Memory and interpreting, the difference between Short-Term Memory and Long-Term Memory, why interpreters rely deeply on Short-Term Memory, and how interpreters can enhance their

21、Short-Term Memory in order to be more effective. With the boosting of Chinese economy and international trade, increasingly more interpreters are needed to help smooth international business. The desired result is to raise the awareness of the importance of short-term memory, and offer students who

22、want to be interpreters, as well as other language learners, advice on how to train their short-term memory. 2 Brief Views on Short-term Memory 2.1 The Definition of MemoryIn every book about memory, there is a definition of memory. “Memory is the most extraordinary phenomenon in the natural world.”

23、 (Thompson and Stephen, 1) “Memory is not a single organ like the heart or liver, but an alliance of systems that work together, allowing us to learn from the past and predict the future.”(Baddeley, 9) Every expert and scientist has their own definition of memory.2.1.1 Mechanic System of MemoryFrom

24、the introduction of this paper, it is not hard to imagine what the world would be like without memory. One would not be able to remember any past or any future event. Each individual would be a single island in the sea, having no connection or relation with each other. One stores so much information

25、 in the “memory store,” that without the information in it, humans would not be humans. In the “memory store,” one puts everything he learns, such as vocabulary, knowledge of language, knowledge of every fact about life, personal experience, skills of sports, music, feelings, understanding of all ar

26、ound him, and so on (Thompson and Stephen, 1). One can hardly name all the things he consciously or unconsciously stored in his memory. It is, then understandable that the definition of memory is elusive. However, scientists have been studying very hard and have discovered the working mechanism of m

27、emory. Shown in Figure 2-3, memories are formed when a group of neurons fires together when activated. At first, Neuron A receives a stimulus, which causes it to set off neuron B. If neuron A fires again quickly, a link is established. Later, neuron A can just fire weakly to set off neuron B. Then,

28、the firing of neurons A and B may set off neighboring neurons C and D. If this repeatedly happens, the four cells become a network and will fire together in the future, thus a memory is formed. A repetition of stimulus will then form the memory (Sousa, 80). In the latter half of this thesis, repetit

29、ion will also mentioned as a way of helping the training of the short-term memory. These procedures are all performed in our brain. What parts of our brain help with our memory? Figure 2-3 (Sousa, 80)2.1.2 Mechanic System of Brain WorksAs is shown in Figure 2-1, our brain is complicated. Different p

30、arts specialize in different tasks, yet corporately work together. The key structures for memory include the cerebral cortex, the hippocampus, the basal ganglia and the cerebellum (Thompson and Stephen, 12). Early surveyors of the brain gave Latin and Greek names to the parts of the brain according

31、to their location, namely forebrain, midbrain, and hindbrain. Another concept proposed by Paul Maclean in the 1960s, described the brain according to the stages of evolution: reptilian, paleo-mammalian, and mammalian (Sousa, 15-16). According to Paul MacLean, the brain stem is the oldest and deepest

32、 area of the brain, which controls and monitors vital body functions, such as heartbeat, respiration, body temperature, and digestion. Above the brain stem, lies the limbic system, or the old mammalian brain. There are three parts of the limbic system that are very important to learning and memory.

33、They are the Thalamus, the Hippocampus (the Greek word for “seahorse”), and the Amygdala (the Greek word for “almond”). Cerebrum is the largest of the four areas. The hemisphere is covered by a thin but tough layer of cells, called the cortex. The frontal Lobe or the frontal cortex is the front of t

34、he cerebrum, lying just behind the forehead. Most of the working memory is located here. The cerebellum (Latin for “little brain”), is located just below the rear part if the cerebrum. There is new evidence that the cerebrum also may help coordinating and fine-tuning our thoughts, emotions, senses,

35、and memories. Lastly, there are brain cells (Sousa, 17-20). For the locations of the interior parts, see Figure 2-2Figure 2-1 (Thompson, 12)Figure 2-2 (Sousa, 17)2.1.3 The Category and Stages of MemoryRichard Atkinson and Richard Shiffrin proposed a model of memories; later the model got a nickname

36、the “modal model”. They assumed that there are three kinds of memories: sensory memory, short-term memory, and long-term memory. See Figure 2-4. In this model, information comes into the brain from the environment. The information will go through a series of brief sensory memory stores and then goes

37、 into a common short-term memory store. These two procedures are assumed to be working memory, capable of manipulating information and relating it to long-term storage (Baddeley, 17).Figure 2-4 (Thompson and Stephen, 26)2.2 The Definition of Short-Term MemoryIn 1890, William James used primary memor

38、y to refer to the contents of our immediate, ongoing awareness. Since then, it has been called immediate memory, short-term memory, and working memory (Thompson and Stephen, 25). However, David A. Sousa, in his book, How the Brain Works refers to the term short-term memory as all of the early steps

39、of temporary memory that leads to long-term memory. He defines short-term memory as including immediate memory and working memory (Sousa, 41). The idea that we have two temporary memories is recent. Sensory data that are not listed move from the thalamus (See Figure 2-1 and 2-2) to the sensory proce

40、ssing areas of the cortex and through the first of two temporary memories called immediate memory or sensory memory according to Thompson and Stephen. In this thesis, the model will be referred to Sousas memory model.2.2.1 Immediate Memory and Working MemoryImmediate memory area can be compared to a

41、s a clipboard, in Sousas model (the model), where we put information briefly until we decide how to deal with the information. According to Sousa, immediate memory operates subconsciously or consciously and holds data for up to about 30 seconds according to Sousa (Sousa, 40-42). Peterson (Peterson a

42、nd Peterson, 193-198) found it to be 6 - 12 seconds, while Atkinson and Shiffrin (Atkinson, R.L., and Stiffrin, R.M., Vol.2) state it is 30 seconds. An individuals experience will determine the importance of the information (Sousa, 41). If X information is of no real importance to a individual, his

43、memory will drop X information out after use. For instance, if one calls 114 for a friends home phone number, but he does not have pen and paper at hand, or he does not know how to record the number into the phone while on the phone, then he has to remember it until he calls his friend or finds a pe

44、n and paper. After that, he may forget the number quickly. According to Sousa, because the number is no longer important to him, it drops out of immediate memory. Sousas theory explains why a lot of conference interpreters cannot remember details about the material they have just interpreted. Under

45、the tension of the conferences, the focus of interpreters is in interpreting the materials, instead of remembering them. Jack C. Peng, a prestigious interpreter in Shanghai, jokingly said during a class in translation and interpreting training at the Transemantix Institute of Interpretation and Tran

46、slation in Shanghai, that as long as he can interpret the material correctly, what the material says is not important to him. But if he knows his next conference will also cover the same topic, Jack says he then always can retain some of the information in his mind. This example illustrates another

47、characteristic of brain processing: the hierarchy of response to sensory input. Because Jack knows the importance of the information, his brain moves the data rapidly to working memory and then maybe long-term memory. This characteristic of memory is considered as a way to enhance memory, because em

48、otions can enhance memory by causing the release of hormones that stimulate the amygdala to signal brain regions to strengthen memory (Sousa, 42).Working memory is the second temporary memory and the place where conscious, rather than subconscious, processing occurs. It is compared to a work table in the model. Scanning experiments show that most of the working memorys activity occurs in the frontal lobes, and other parts of the brain are usually called to help.
