Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
Most people can remember a phone number for up to trirty seconds. When this short amount of time elapses, however, the numbers are eerased from the memory. How did the information get there in the first place? Information that makes its way to the short term memory (STM) does so via the sensory storage area. The brain has a filter which only allows atimuli that is of immediate interest to pass on to the STM, also known as the working memory.
There is much debate about the capacity an duration of the short term memory. The most accepted theory comes from George A.Miller, a cognitive psychologist who suggested that humans can remember approximately seven chunks of information. A chunk is defined as a meaningful unit of information, such as a word or nam rather than just a letter or number. Modern theorists suggest that one can increase the capacity of the short term memory by chunking or classifying similar information together. By organizing information, one can optimize the STM, and improve the chances of a memory being passed on to long term storage.
When making a conscious effort to memorize something, such as information for an exam, many people engage in “rote rehearsal”. By repeating something over and over again, one is able to keep a memory alive. Unfortunately, this type of memory maintenance only succeeds if there are no interruptions. As soon as a person stops rehearsing the information, it has the tendency to disappear. When a pen and paper are not handy, people often attempt to remember a phone number by repeating it aloud. If the doorbell rings or the dog barks to come in before a person has the opportunity to make a phone call, he will likely forget the number instantly. Therefore, rote rehearsal is not an efficient way to pass information from the short term to long term memory. A better way is to practice “elaborate rehearsal”. This involves assigning semantic meaning to a piece of information so that it can be filed along with other pre-existing long term memories.
Encoding information semantically also makes it more retrievable. Retrieving information can be done by rocognition or recall. Humans can easily recall memories that are stored in the long term memory and used often; however, if a memory seems to be forgotten, it may eventually be retrieved by prompting. The more cues a person is given (such as pictures), the more likely a memory can be retrieved. This is why multiple choise tests are often used for subjects that require a lot of memorization.
Which of the following is NOT supported by the passage?
A. The working memory is the same as the short term memory
B. A meomry is kept alive through constant reprtition
C. Cues help people to recognize information
D. Multiple choise exams are the most difficult
Đáp án D.
Clue: “The more cues a person is given (such as pictures), the more likely a memory can be retrieved. This is why multiple choice tests are often used for subjects that require a lot of memorization”: Càng nhiều gợi ý được cho (như trang ảnh) thì càng nhiều khả năng trí nhớ được phục hồi. Đó là lý do tại sao nhiều bài kiểm tra nhiều lựa chọn thường xuyên được sử dụng cho các đối tượng đòi hỏi nhiều sự ghi nhớ.
Qua dẫn chứng trên ta thấy rằng tác giả đề cập đến bài thi trắc nghiệm nhiều lựa chọn chính là việc cung cấp nhiều dấn chứng để giúp trí nhớ được phục hồi, chứ không nói gì đến việc bài thi kiểu này là khó nhất → Đáp án đúng là D. Multiple choice exams are the most difficult.
Các đáp án còn lại là sai vì các thông tin đều được cập trong đoạn văn:
A. The working memory is the same as the short term memory – dẫn chứng ở câu “…pass on the STM, also known as the working memory.”
B. A memory is kept alive through constant repetition – dẫn chứng ở đâu: “By repeating something over and over again, one is able to keep a memory alive”.
C. Cues help people to recognize information – (Tham khảo clue phía trên).
