[单项选择]Psychologists originally used the term short-term memory to refer to the ability to hold information in mind over a brief period of time. As conceptions of short-terra memory expanded to include more than just the brief storage of information, psychologists created new terminology. The term working memory is now commonly used to refer to a broader system that both stores information briefly and allows manipulation and use of the stored information.
Psychologists often study working memory storage by examining how well people remember a list of items. In a typical experiment, people are presented with a series of words, one every few seconds. Then they are instructed to recall as many of the words as they can, in any order. Most people remember the words at the beginning and end of the series better than those in the middle. This phenomenon is called the serial position effect because the chance of recalling an item is related to its position in the series. In this experiment, re
A. equal to

[单项选择]Social psychologists arc used to hearing that their experiments are a waste of time because they just prove the obvious, and tell us what we always knew. But there is a very simple and effective riposte to this accusation. The trouble with folk-wisdom (what we always knew) is that it tends to come in pairs of statements, both of which are obviously’ true, but which—unfortunately—are mutually exclusive. For example, birds of a feather flock together, but what about the attraction of opposites Experiments may not be as much fun as intuitions, but they sometimes tell us which proverbs are actually true, or (moor often) in what circumstances which apply.
There is one other preconception to be removed before tackling the question of whom we like and love, whom we find attractive and make friends with: "Why bother to study an area in which we are all expert practitioners" Well, ff you believe that, have a word with a marriage guidance counselor, a psychiatrist, or someone involved in in
A. to defend the experiments of social psychologists
B. to explain why folk-wisdom tends to come in pairs of contradictory statements
C. to discuss the many facets of friendship
D. to show the complexity of behavioral science

Types of risks
So far we have used the term "risk" rather loosely. One type of risk is default risk, that is, the risk that the borrower will simply not repay the loan, due to either dishonesty or plain inability to do so. Another type of risk, called purchasing - power risk, is the risk that, due to an unexpectedly high inflation rate, the future interest payments, and the principal of the loan when finally repaid, will have less purchasing power than the lender anticipated at the time the loan was made. A similar risk is faced by borrowers. A borrower may cheerfully agree to pay, say, 15 percent interest, expecting that a 12 percent inflation rate will reduce the real value of the loan. But inflation may be only 4 percent.
A third type of risk is called "interest - rate risk" or "market risk", tha
A. The risk factor in a portfolio can be reduced by including assets whose risks are complementary, i. e. , if one loses value because of particular circumstances the other gains because of those circumstances.
B. One should try to eliminate all risks from one’s portfolio by only buying very safe shares.
C. Under no circumstances should a careful investor add high risk assets to his/her portfolio even though the income or capital gain that may be received from that high risk asset could be very large.
