案例：原苏联心理学家彼得罗夫斯基设计了一个实验：被试者是一些四年级、七年级和九年级的学生。给学生一张问卷，其中有几条关于道德问题的判断，学生应对这些判断表示赞成或反对。问题很简单，每个学生都能根据公认的准则作出回答。过了一段时间之后，把这些道德的判断列入一张更长的项目单之中，而在学生回答之前给予暗示，指明其他人都赞成错误的判断。在这种情况下，只有极少数人接受暗示、屈从压力而改变其原来的主意，绝大多数人并没有改变主意。
结合案例资料请回答：
（1）这一实验结果说明了什么管理现象出现这一现象的原因是什么
（2）个体对群体的压力不予接受时的表现类型还有哪些
（3）如何在管理实际中进行有效的群体压力的管理

Passage Four
Television carries more national advertising than any others in the United States. The same is true in some smaller countries such as Spain and Portugal, where it is the only medium reaching a general national audience. In many countries, Sweden and Denmark, for example--the stateowned television accepts no advertising. In many other countries the amount of commercial time is extremely limited, as in France, Germany, and Italy. Soviet state-owned television began accepting a limited amount of advertising in 1988.
The chief reason for the population of television among United States advertisers is that it it reaches a vast number of people at the same time. While it can cost well over 100,000 dollars, a 30- second commercial on network television can be seen and heard by as many as 25 million viewers.

A. Radio.
B. Newspaper.
C. Television.
D. Internet.
