There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do.
In the ancient world, as is today, most boys played with some kinds of toys and most girls with others. In societies where social roles are rigidly determined, boys pattern their play after the activities of their fathers and girls after the tasks of their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world.
What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality of toys with regard to their development in all parts of the world and their persistence to the present that is amazing. In Egypt, the Americas, China, Japan and among the Arctic peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.
Because toys can be generally regarded as a kind of art form, they have not been subject to technological leaps that characterize inventions for adult use. The progress from the wheel to the oxcart to the automobile is a direct line of ascent. The progress from a rattle used by a baby in 3000 BC to one used by an infant today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the times and subject to the limitations of available materials.
The reason why the toys most boys play with are different from those that girls play with is that ______.

People can be addicted to different things—e.g., alcohol, drugs, certain foods, or even television. People who have such an addiction are compulsive, i.e., they have a very powerful psychological need that they feel they must satisfy. According to psychologists, many people are compulsive spenders: they feel they must spend money. This compulsion, like most others, is irrational—impossible to explain reasonably. For compulsive spenders who buy on credit, charge accounts are even more exciting than money. In other words, compulsive spenders feel that with credit, they can do anything. Their pleasure in spending enormous amounts is actually greater than the pleasure that they get from the things they buy.
There is a special psychology of bargain hunting. To save money, of course, most people look for sales, low prices and discounts. Compulsive bargain hunters, however, often buy things they don't need just because they are cheap. They want to believe that they are helping their budgets, but they are really playing an exciting game: when they can buy something for less than other people, they feel that they are winning. Most people, experts claim, have two reasons for their behavior. a good reason for things that they do and the real reason.
It is not only scientists, of course, who understand the psychology of spending habits, but also business people. Stores, companies, and advertisers use psychology to increase business: they consider people's needs for love, power, or influence, their basic value, their beliefs and opinions, and so on in their advertising and sales methods.
Psychologists can often use a method called "behavior. therapy" to help individuals solve their personality problems. In the same way, they can help people who feel that they have problems with money.
According to the psychologists, a compulsive spender is one who spends large amounts of money ______.
Violent lyrics in songs increase aggression-related thoughts and emotions and could indirectly create a more hostile social environment, a study released on Sunday by a U.S. psychology association found. The Washington D. C.-based American Psychological Association (APA) released the study, resulting from five experiments involving over 500 college students, in the May issue of the Journal of Personality and Social Psychology.
The violent songs increased feelings of hostility without provocation or threat, according to the study. It said the effect was not the result of differences in musical style, specific performing artist or arousal properties of the songs. Even the humorous violent songs increased aggressive thoughts, the study said.
The group said the study contradicts a popular notion that listening to angry, violent music actually serves as a positive catharsis for people.
The music industry came under criticism from lawmakers in October for failing to use more descriptive parental advisory labels that specify whether the music contains sex, violence or strong language:
But the Recording Industry Association of America (RIAA) has said that current CD labels give parents enough information without violating the right to free expression. The RIAA is the trade group for the world's five big labels, including AOL Time Warner Inc., EMI Group Plc, Bertelsmann AG, Vivendi Universal's Universal Music and Sony Corp.
Results of the APA's experiments showed that violent songs led to more aggressive interpretations of ambiguously aggressive words and increased the relative speed with which people read aggressive versus non-aggressive words. "Such aggression-biased interpretations can, in turn, instigate a more aggressive response, verbal or physical, than would have been emitted in a nonbiased state, thus provoking an aggressive escalatory spiral of antisocial exchanges," said researcher Craig Anderson, in a statement.
While researchers said repeated exposure to violent lyrics could indirectly create a more hostile social environment, they said it was possible the effects of violent songs may last only a fairly short time.
The word "catharsis" in paragraph 3 most probably means ______.
