Childhood is a critical period for learning and development, and early education has a crucial impact on children's development. This study aims to explore the effects of animation games on preschool children's working memory and its mechanism based on Spinoza's "Nature's Way" theory. Through literature review and experimental research, it is found that animation games can significantly promote the working memory of preschool children. At the same time, studies have found that visual, auditory, kinesthetic and other stimulation methods of animation games can enhance children's attention, thinking ability and information processing speed, thereby improving their working memory performance. In addition, the interactivity and fun of animation games is also one of the important mechanisms for them to affect working memory. Working memory is the most important part in the development of children's cognitive ability. Therefore, how to promote the development of children's working memory in preschool education has always been a hot research topic in the educational field. Based on Spinoza's "natural way" theory, this paper starts with the influence of animation games on children's working memory, summarizes the theoretical mechanism of animation games promoting children's working memory, and puts forward suggestions for the application of this theory in preschool education. It provides inspiration for improving children's working memory in preschool education, and provides reference for optimizing children's education and teaching.
