这一主题中备课的基本任务,就是要向学生证明:人类高级神经活动底特点在於他有与第一信号系统密切地相互作用着的第二信号系统存在着。第一课巴甫洛夫关於第一与第二信号系统的学说上一课里学过了关於大脑半球皮层中兴奋活动和抑制活动的材料。提问过这一主题后,应当使学生回想关於条件反射作用在动物生活中的重要性。教师提示说明:动物在历史发展过程中获得了一些条件,使它们能够更广泛地理解周围环境并且更完善地适应外界条件。向学生们提问:为什么条件反射能使动物适应(?) The basic task of lesson preparation in this theme is to prove to students that the advanced feature of the human nervous activity is that he has a second signaling system that interacts closely with the first signaling system. Lesson 1 Pavlov’s Doctrine on First and Second Signaling Systems In the previous lesson, you learned about exciting and inhibitory activities in the hemisphere of the brain. After asking this theme, students should be reminded of the importance of conditional reflexes in animal life. Instructor Note: Animals have acquired some conditions during their historical development, enabling them to understand the environment more widely and adapt more well to external conditions. Ask the students why conditioned reflexes adapt to animals (?)
