Generally speaking, the left hemisphere remembers more, but people's right hemisphere has stronger memory ability. The right hemisphere is image memory and the left hemisphere is abstract memory. There are stories, and now primary school textbooks are all with pictures, which is helpful for people's memory. Now the development of the right brain is mainly based on image memory. There are functional differences between the two hemispheres: the left hemisphere is superior to the right hemisphere in analyzing time patterns, distinguishing verbal and nonverbal sound stimuli and visual and tactile events. Strong auditory event analysis ability is the basis of left hemisphere language advantage. The right hemisphere has a limited understanding of language, but it also has a high degree of intellectual activity, which is stronger than the left hemisphere in some aspects. For example, the ability to understand and judge spatial geometric images, the ability to perceive image signals, and the ability to recognize and remember tones are better than those in the left hemisphere. In terms of memory ability, the left hemisphere has much stronger memory ability for language information than the right hemisphere, but it is difficult to remember complex visual and tactile information. It is difficult for the right hemisphere to remember language materials, but it has a good memory for complex pictures and tactile information. According to the conclusion of experimental research, the independent left hemisphere of the brain has the functions of dominating speech, writing, mathematical operation and abstract reasoning. The left hemisphere plays a leading role in controlling the regulatory activities of the nervous system. The independent right hemisphere is superior to the left hemisphere in space, music and thinking in images. In other words, the functions of the two hemispheres of the brain are very specialized, and they have their own division of labor and cooperate with each other.
