发散思维是围绕中心问题广泛开展思考、最大限度地开拓思路的思维形态;而辐合思维则是在发散思维的基础上,逐步缩小思考范围、选择合理思路、获取最佳方案的思维形态.发散与辐合,是思考过程中相辅相成的两个方面,在猜谜与解题中都是缺一不可的. Divergent thinking is a thinking pattern that focuses on central issues to develop extensive thinking and maximize the development of ideas. On the other hand, convergent thinking is based on divergent thinking. It gradually narrows the scope of thinking, selects reasonable ideas, and obtains the optimal solution. Convergence and convergence are two aspects that complement each other in the process of thinking. They are indispensable in guessing and solving problems.
