Most people can remember a phone number for up to thirty seconds. When this short amount of time elapses, however, the numbers are erased 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 stimuli that is of immediate interest to pass on to the STM, also known as the working memory.
There is much debate about the capacity and 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 name 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 recognition 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 choice tests are often used for subjects that require a lot of memorization.

The correct answer is B. This is a factual question.
- Choice A is the opposite of what happens.
- Choice C is what a person should try to do when memorizing something.
- Choice D is not mentioned.
2. The word elapses in paragraph 1 is closest in meaning to:
B) adds up
The correct answer is A.This is a vocabulary question.
3. All of the following are mentioned as places in which memories are stored EXCEPT the:

D) maintenance area
The correct answer is D. This is a negative factual question.
- Choice A is mentioned in the first paragraph.

- Choice C is mentioned in the first paragraph.
4. Why does the author mention a dog's bark?
A) To give an example of a type of memory
B) To provide a type of interruption
C) To prove that dogs have better memories than humans
D) To compare another sound that is loud like a doorbell
The correct answer is B. This is an author purpose question.
- Choice A is incorrect because it is not the "reason" the author mentions it.

B) more efficient than chunking
C) ineffective in the long run
D) an unnecessary interruption
The correct answer is C. This is a factual question.
- Choice A is contradicted by "not an efficient way".
- Choice B is incorrect because these two terms are not compared.
- Choice D is illogical.

D) regular The correct answer is A
. This is a vocabulary
question. 10. Which of the following is NOT supported by the passage?
A) The working memory is the same as the short term memory.
B) A memory is kept alive through constant repetition.
C) Cues help people to recognize information.
D) Multiple choice exams are the most difficult. Explanation:
The correct answer is D
- Choice A is mentioned in paragraph one.
- Choice B is mentioned in paragraph three (though an interruption will destroy it).
- Choice C is mentioned in the last paragraph.

. This is a vocabulary
question. 12. Which of the following best provides the important informaton in the highlighted sentence from the passage. Incorrect answer choices leave out essential information or change the meaning of it
A) Prompting is the easiest way to retrieve short term memory after an extended period of time.
B) A memory can be retrieved by prompting, in a case where it has been rarely used.
C) It's easier to remember short term memories than long term memories due to regular prompts.
D) Recalling a long term memory that is often used is easy, while forgotten memories often require prompting. Explanation:
The correct answer is D
- Choice A changes the meaning of the information.
- Choice B leaves out essential information about the long term memories that are used often.
- Choice C changes the meaning of the information.

question. 13. An introductory sentence for a summary of the passage is found below. Complete the summary by choosing the THREE answer choices that contain the most imporant ideas in the passage. Some sentences do not fit in the summary because they provide ideas that are not mentioned in the passage or are only minor ideas from the passage. This question is worth 2 points.
The brain stores information that a person may need in the immediate future in a place called the short term memory (STM).
1. Most people can only remember numbers for a short time.
2. Many psychologists agree that only a certain amount of information can be stored in the STM at once.
3. Some techniques for memorization don't work because of potential interruptions.
4) Elaborate rehearsal is generally considered less effective than rote rehearsal.
5) Assigning meaning to information makes it easier for the brain to retrieve. Explanation:
The correct answers are 2, 3, and 5
