概述皮亚杰认知发展阶段理论的主要内容。

答案

参考答案:

解析:皮亚杰认为,在个体从出生到成熟的发展过程中,认知结构在与环境的相互作用中不断重构,从而表现出具有不同性质的不同阶段,据此,他把人的发展分为四个阶段: (1)感知运动阶段(0~2岁)。这一阶段的认知活动,主要是通过探索感知觉与运动之间的关系来获得动作经验,一般从对事物的被动反应发展到主动的探究,其认识事物的顺序是从认识自己的身体到探究外界事物;而且儿童渐渐获得了客体永恒性。本阶段儿童还不能用语言和抽象符号为事物命名。 (2)前运算阶段(2~7岁)。运算是指内部化的智力或操作。这一阶段儿童已经具有了符号功能,表象日益丰富,开始能运用语言或较为抽象的符号来代表他们经历过的事物。前运算阶段的儿童的心理表象是直觉的物的图像,还不是内化的动作格式;他们的认知活动具有相对具体性,还不能进行抽象的运算思维,思维具有不可逆性和刻板性等特点,儿童尚未获得物体守恒的概念,不知道物体事物不论其形态如何变化,其物体质量是恒定不变的。 (3)具体运算阶段(7~11岁)。这一阶段儿童的认知结构已发生了重组和改善,思维具有一定的弹性,思维可以逆转,能凭借具体事物或从具体事物中获得的表象进行逻辑思维和群集运算。但这一阶段儿童的思维仍需要具体事物的支持。儿童还不能进行抽象思维。 (4)形式运算阶段(11~16岁)。这一阶段儿童的思维已超越了对具体的可感知的事物的依赖,儿童的思维是以命题形式进行的,并能发现命题之间的关系;能够根据逻辑推理、归纳或演绎的方式来解决问题;能理解符号的意义、隐喻和直喻,能做一定的概括,其思维发展水平已接近成人的水平。

单项选择题

Cooperation is the common endeavor of two or more people to perform a task or reach a jointly cherished goal. Like competition and conflict, there are different forms of cooperation, based on group organization and attitudes.
In the first form, known as primary cooperation, group and individual unite. The group contains nearly all of each individual’s life. The rewards of the group’s work are shared with each member. There is an interlocking identity of individual, group, and task performed. Means and goals become one, for cooperation itself is valued.
While primary cooperation is most often characteristic of preliterate societies, secondary cooperation is characteristic of many modem societies. In secondary cooperation, individuals devote only part of their lives to the group. Cooperation itself is not a value. Most members of the group feel loyalty, but the welfare of the group is not the first consideration. Members perform tasks so that they can separately enjoy the fruits of their cooperation in the form of salary, prestige, or power. Business offices and professional athletic teams are examples of secondary cooperation.
In the third type, called tertiary cooperation or accommodation, latent conflict underlies the shared work. The attitudes of the cooperating parties are purely opportunistic; the organization is loose and fragile. Accommodation involves common means to achieve antagonistic goals; it breaks down when the common means cease to aid each party in reaching its goals. This is not, strictly speaking, cooperation at all, and hence the somewhat contradictory term antagonistic cooperation is sometimes used for this relationship.

According to the passage, why do people join groups that practice secondary cooperation

A.To share the happiness with others.

B.To get rewards for themselves.

C.To associate with people who have similar backgrounds.

D.To defeat a common enemy.
