2. Overall perception and partial perception training. First train the individual parts of the object, then train the whole part of the object, and finally train both the individual parts and the whole.
3. Perceptual training of color and shape. Train shape abstraction first, then color abstraction, and finally train the same abstraction.
4. Physical and perceptual training. First, train to know circles, squares and triangles, then train to spell two triangles into a triangle and two semicircles into a circle, then train to know ellipses, diamonds, pentagons, hexagons and cylinders, then train to fold rectangular pieces of paper into squares and square pieces of paper into triangles, and finally train to know Chinese characters.
5. Size perception training. First train to judge the size of a circle, a square and an equilateral triangle, and then train to judge an ellipse, a diamond and a pentagon. Let children find more regular graphic exercises.
6. Orientation and perception training. First train to distinguish between up and down, then train to distinguish between before and after, and finally train to distinguish between the left and right parts of your body.
7. Memory training. The capacity of short-term memory is 5~9 items. In order to exaggerate the capacity of short-term memory, the method of chunking can be adopted, that is, small memory units are combined into large memory units (if a single Chinese character is changed into a two-word word to remember, the memory capacity will be doubled). Then the short-term memory information is retelled and transferred to the long-term memory system. Training should mix the familiar content with the unfamiliar content and repeat it repeatedly (review the previous content at the beginning of each training) until it is transferred to the long-term memory system. Card (event) memory training is the same as life event memory training.
8. Life memory training. A few days before training, weeks before training, months before training, and finally a year ago.
9. Thinking development training. First train intuitive action thinking, then train concrete image thinking, and finally train abstract concept thinking. Thinking training includes concept, judgment, reasoning, understanding and classification. Many training concrete image thinking and abstract concept thinking are linked together, and the training should be gradual.
