Abstract:edgPsychology is a science. The scientific target of psychology is the mental phenomena and processes of biological entities, which makes the methodology of psychological research unconventionally difficult and complex. The significant characteristic of methodology in psychological research is to widely borrow methodology and techniques from other disciplines. In recent history, psychologists have developed many exquisite designs, powerful paradigms, and data analysis approaches. The emergence of Cognitive Neuroscience in late 20 century becomes a milestone of the development and history of psychological science. The growth of multivariate statistics, such as Structure Equation Modeling, Hierarchical Liner Models, extend psychological research to applied areas, such as education, development, management, economy, medicine, and social sciences. While psychological research in China endeavored to maintain its scientific roots, meet the needs of the society, and made great progress in catching up with the es, much improvement is desired in terms of the number of psychological researchers, in the area of longitudinal studies, neuropsyhological studies, and interdisciplinary studies.
