中文摘要： 认知诊断(cognitive diagnosis)有助人们更好地了解人类内部心理活动规律及加工机制，实现对个体认知发展实况（含优点与缺限）的诊断评估，以促进个体全面发展。目前认知诊断正引起国内外学者的广泛关注，并成为现代心理测量学的重要发展领域。本项目致力于这一前沿领域研究：一方面针对当前Q矩阵理论的不足，对其相关原则、技术、方法进行研究，以进一步完善并优化Q矩阵理论，并采用Monte Calor方法验证其合理性和科学性；另一方面构建新的适用面更广的认知诊断计量模型，并采用国际上先进的MCMC 算法实现模型的参数估计。这些关于认知诊断的基础性研究对于拓宽其在实际中的应用及促进其更好地为实践服务具有重要意义。

英文摘要： The cognitive diagnosis enabled us to learn more about the internal psychological rules and processing mechanism of human, and to realize the diagnosis assessment on individual cognitive developing status, which provided his/her cognitive procedure, processing skills and knowledge structures, including their advantages and deficiencies. All these information were useful for the teaching and learning, and important to the development of individual. Recently, because of the wonderful characteristics of cognitive diagnosis, it was causing more and more attentions of scholars and gradually becoming an important developing area in modern psychometric. This project was devoted to make research on this advanced field through three studies: According to the inperfection of Q matrix theory, it attempt to do further investigation on the related princinples, techniques, and methods, expecting which could complete the Q matrix theory. The Monte Calor method will be used to testify the rationality and scientificity. Secondly, it try to develop a new cognitive diagnosis measurement model which might be applied in more broadened fields. The MCMC algorithm will be used to realize the parameter estimation of the model. All these work were basic theory researches, which had important significance in broadening the application
