In recent years, the study of the psychological mechanism of the development of thinking become the field of development of thinking, a fairly compelling theme. Processing speed and working memory as an indicator of the psychological mechanism of the development of thinking in children and adolescents has become a development research topics at the forefront. In this study, starting from the behavioral level, 248 healthy children and adolescents aged 10-18 were expounded processing speed, working memory in the development process of thinking, clear processing speed and working memory in thinking in the development process of the relationship between , thus the psychological mechanism of the development process of thinking of children and adolescents have a more comprehensive understanding of the system. The contents include: the relationship of the development characteristics of children and adolescents and processing speed, working memory development characteristics, characteristics of the development of thinking, age, processing speed, working memory and thinking development of relations, as well as processing speed and working memory. Digital copying task to task transcribe letters, letter string comparison task symbol string comparison task examine processing speed; digital working memory task with visual spatial working memory tasks examine working memory; Raven numerical reasoning tests, quizzes, cartel culture fair tests examine the thinking. The processing speed tasks and thinking tests for the unified timing bodies pen and paper test, the test of working memory tasks on the computer about every 2 weeks. Exploratory analysis of the data obtained, including variance analysis and hierarchical multiple regression analysis, the simple analysis of variance, repeated measure analysis of variance, and other methods to measure a variety of variables, to observe the processing speed, working memory in the development process of thinking role in the amount of their relationship. Comprehensive analysis and conclusions are as follows: (1) children and adolescents of processing speed, working memory, thinking with a significant age difference, the processing speed, working memory, and thinking ability with increasing age (10-18 years old) and a growth function the form of improved; (2) hierarchical multiple regression analysis, the simple analysis of variance, repeated measures analysis of variance from different angles on different levels: working memory and processing speed of the action of the thinking of about 85.18%, 68.75%, respectively, 66.67%, the amount of working memory thinking were approximately 72.76%, 56.34%, 51.19%, the processing speed of thinking was approximately 63.73%, 46.31%, 42.40%, indicating that the working memory in the development process of thinking and processing speed plays an important role, is greater than the processing speed and working memory role in the development of thinking; (3) further hierarchical regression analysis, the processing speed working memory capacity of 65.18 percent, the role of working memory processing speed 57.66% of the working memory processing speed, processing speed is greater than the role of working memory, processing speed may be the intermediary of age and working memory; (4) the development of thinking, the working memory may play a direct regulatory role basis, the development of working memory may be based on the growth of age-related processing speed, processing speed may be from the development of working memory only a direct regulatory role in the development process of thinking, working memory processing speed may play more direct and general role. The psychological mechanism of the development of thinking from the perspective of this study can be summarized as follows: plays an important role in the development process of thinking, working memory and processing speed and working memory is greater than the processing speed of development of thinking. Processing speed may be the intermediary of age and working memory, processing speed may be the development of working memory only from a direct regulatory role, working memory development thinking may play a direct regulatory role in the development process of thinking, working memory processing speed may play a more direct, more general role.
