本文介绍了巴甫洛夫从行为的观点上解释了第二信号系统的概念。第二信号系统的活动服从于第一信号系统的规律,其特点具有抽象和概括的性质。精神病乃是第二信号系统异常的表现。巴甫洛夫还提出了艺术家类型和思想家类型等两种高级神经的类型,但对第二信号系统的脑结构,巴甫洛夫未具体说明。西方进行割裂脑研究的科学家,提出大脑两半球在功能上各有优势。笔者认为,脑的正常工作总是整体性质的。
This article describes Pavlov’s interpretation of the concept of the second signal system from the point of view of behavior. The activity of the second signal system is subject to the laws of the first signal system, and its characteristics are abstract and general. Psychosis is the manifestation of an abnormal second signal system. Pavlov also proposed two types of advanced neurons such as artist type and thinker type, but Pavlov did not specify the brain structure of the second signal system. Scientists in the Western world who conducted split-brain research suggest that both cerebral hemispheres have functional advantages. The author believes that the normal work of the brain is always of an overall nature.
