2、ns and actions ( if. then. production or production system)三、认知在心理系统中的地位 o 1.认知与意识认知与意识 The Cognition & Consciousnesso 2.认知与智力、思维的关系认知与智力、思维的关系 The Relationship between Cognition, Intelligence, & thinking1.认知与意识 1. o 有意义的识记：有意义的识记：诸如，儿童所能记住的某个词列的诸如，儿童所能记住的某个词列的数量，儿童在辨认某些图片、字词时所花的时间或数量，儿童在辨认某些图片、字词时所

3、花的时间或计算某道算术题的正确性等。计算某道算术题的正确性等。Meaningful Memorization: for example, whether children can remember a word list, the number of children identifying some pictures, words, or when the time or the validity of the a math problem, etc.o 但心理学家所真正感兴趣的并不是这些容易被观察但心理学家所真正感兴趣的并不是这些容易被观察到的内容，而是那些潜藏在这些行为下面的加工过到的内

4、容，而是那些潜藏在这些行为下面的加工过程和技能。程和技能。But psychologists are not really interested in the content which can be easily observed, rather they are interested in the hidden processes and skills underlining the behavior.o6岁儿童和14岁少年在完成某项认知任务时，所使用的认知操作各是什么？ What are the cognitive operations used by 6 years old child

5、ren and 14 years old children, while performing on a cognitive task,? o对词义的辨别速度是如何反映主体对信息的不同贮存方式的？Does the difference in storing of the main body of information affect in identifying the difference between memory? o婴儿是如何利用其关于自己母亲的心理表象去区别其他形象的？How do babies use their mothers psychological representat

6、ion to reflect between different images? o这种心理表象又是如何产生的？如何被不断精确化的？等等。How is this kind of psychological representation generated? How constantly accurate it is? And so on. o 简言之，认知发展心理学家所关心的问题是简言之，认知发展心理学家所关心的问题是，儿童进行认知活动的儿童进行认知活动的内在过程内在过程以及导致儿以及导致儿童认知发展的童认知发展的内在机制内在机制。In short, cognitive psychologis

7、ts are concerned with the childrens Internal process of cognitive activities and the Internal mechanism of cognitive development in childreno 无意识的加工过程：认知不仅寓于我们意识水平之上的那些认识活动中，同时也寓于人们日常生活的某些非意识行为的过程中。Unconscious processes: cognition not only resides in day-to-day life at conscious level in activities,

8、 but also in unconscious through different involuntary processes.n 例如，当我们平时在听收音机和看报纸时，我们对每一个声音和字符的辨认都似乎是在不知不觉中进行的，其实，在这些活动中包含着非常复杂的认知机制。 Suppose, we are looking at the newspaper while listening to radio at the same time, we attend all the characters and sounds unconsciously, in fact, these activitie

9、s contain very complex cognitive mechanism2.认知与智力、思维的关认知与智力、思维的关系系 2. o 智力（intelligence）、思维（thinking）、认知（cognition）这三个词之间具有很大的相似性，即都表示人在认识方面的特点和能力。Intelligence, thinking and cognition have a great deal of similarity, that is to say, through a persons aspect of knowledge and ability.o “智力”是指人认识、理解事物和

10、现象并运用知识、经验解决问题能力的总和，它包括所有的与认识活动有关的能力；Intelligence means people know and understand the things and their manifestations and it includes all associated with cognitive activities like the total knowledge, experience, and ability to solve the problem.2.认知与智力、思维的关认知与智力、思维的关系系 2. n“思维”是人运用表象和概念进行分析、综合、判断、

11、推理等认识活动的过程，是智力的最高级和核心的部分。Thinking consists of using the process of cognitive activities like the representation and conceptual analysis, creation, judgment and reasoning. The higher mental process are the core part of intelligence.n智力包含思维，思维是智力中的灵魂。Intelligence consists of thinking, while thinking i

12、s the soul in intelligencen从广义的角度使用“认知”这个概念时，其含义与“智力”的含义等同；当从狭义的角度使用时，其含义与“思维”更接近。From the angle of the generalized concept of cognition, the adequate implication of the meaning of “intelligence” is formed, and from a narrow concept of it, the meaning of intelligence to used for identification. o 为了

13、建立一种理论来说明人的认知或某种认知活动，或者用计为了建立一种理论来说明人的认知或某种认知活动，或者用计算机从形式上来描述人的认知的结构过程，现代认知心理学特算机从形式上来描述人的认知的结构过程，现代认知心理学特别重视建构各种各样的认知模型。有些模型描述了从信息输入别重视建构各种各样的认知模型。有些模型描述了从信息输入内部加工内部加工信息输出的全部过程；有些模型则只是针对信息输出的全部过程；有些模型则只是针对个别认知活动的局部过程建构的。个别认知活动的局部过程建构的。In order to establish a kind of theory of cognition or cognitive

14、 activity, example of computer form is used to describe the structure of the human cognitive process. Modern cognitive psychology attaches great importance to the construction of all kinds of special cognitive model. Some models describe the information input, internal processing, information output

16、象的有组织的系统中。 o Construction Model is mainly based on the principles of resemblance, observed facts, reasoning, and then draws some theoretical concepts to organize all kinds of facts and phenomena and th e ir relationships into an abstract organized system. 举例：o “儿童解决数学应用题的认知结构模型”（见杨东.儿童解决学科问题认知模型的理论建

23、ychology. Cognitive psychology research orientation is generated by the impact of earlier experimental psychology and psychoanalysis. 讨论 o 有人认为认知心理学不过是回退到Wundt时期的实验心理学而矣，这种认识是错误的。二者的区别表现在以下几个问题上：n （1）高级心理过程能否用实验进行研究；n （2）是否研究无意识；n （3）方法的区别，注重实验还是依靠内省；n （4）概念、理论和技术手段的不同。Discussiono Some people consid

24、er cognitive psychology to the period of Wundts experimental psychology, this understanding is wrong. The following questions can prove it otherwise:o (1) Whether the higher mental processes be studied experimentally;o (2) Can we or can not study the unconscious;o (3) the method is different, should

25、 we pay attention to the experimental method or introspection?o (4) the concept, theory and techniques are different.o 心理学上的第一次革命。Watson高举行为主义大旗，提出只有外显的行为才是心理学研究的唯一对象，反对研究意识，S-R。o 认知心理学受到了行为主义，特别是新行为主义方法上的影响，用科学的方法去进行实证的心理学研究。如Tolman强调SOR。o 行为主义大约盛行了40年，它的影响至今仍在。由于它的极端性，孕育了新兴学派的诞生。 行为主义o The first r

26、evolution in psychology. Watson proposed the standard behavioristic theory, and puts forward the idea that only explicit (observable) behavior should be the object of psychological research, he opposed the research on consciousness, S - R.o Cognitive psychology welcomed behaviorism, especially that

27、the impact of new research methods of behaviorism, used scientific methods to conduct empirical research in psychology. For example, Tolman emphasized the S-O-R concept.o Behaviorism was popular for about 40 years, and is still effective today. But due to its stubborn ideas, it gave way to neo-behav

28、iorism.o 主要研究意识，试图揭露有别于生理机制的心理过程，对知觉、思维等研究的贡献最大。反对把人看成被动的刺激反应器，强调人组织和解释感觉信息的主动性，这与认知心理学的观点是一致的。 格式塔学派o Mainly concerned with consciousness research, trying to reveal different forms of the physiological mechanism of the mental process. Their biggest contribution include research on perception and th

29、inking. They opposed the idea of people being passive stimulation reactors, and emphasized on the idea that the people organize and interpret sensory information, this view is consistent with cognitive psychology.o 认知心理学用实验的方法研究人脑中的认知过程，被称为心理学的第二次革命。o 1956年，几项重要的研究代表了心理学的信息加工观点。o 1967年Neisser发表了心理学史

30、上第一部以认知心理学命名的专著。认知心理学迅速发展，其影响之大是任何一个心理学思潮或流派都无法相比的。 二战后心理学的发展o Cognitive psychology used experimental method to study the cognitive process of human brain, this is considered as the second revolution in psychology.o In 1956, Several important studies represent a psychological point of view of inform

Rapid development took place in the field of cognitive psychology, an incomparable impact was witnessed in the cognitive school of thought.三、认知心理学的影响o 1、对普通心理学和实验心理学的影响

32、 a）扩大了心理过程的研究领域； b）使研究从心理物理函数走向内部心理机制； c）从分析性研究转向综合性研究； d）开始重视个别差异和个案研究；o 1.

Great theoretical contributions.: it has application in the fields of personality psychology (cognitive style, schema), the social cognition (such as how people perceive them

And the reaction time of AA and Aa also gradually decreased, when the time interval was increased to 2 seconds, the difference is very small.
