The interdisciplinary approach of System Dynamics (SD) offers a powerful framework for understanding and addressing psychological processes. This article explores how SD can be applied to psychological research and practice, focusing on the analysis of mental processes, training, awareness, managing complexity, thinking tools, and the sharing of mental models. The potential of SD to improve our understanding of complex psychological phenomena and enhance intervention strategies is discussed. Introduction Psychological processes are inherently complex, involving multiple interacting variables and feedback loops. Traditional linear models often fall short in capturing this complexity. System Dynamics (SD), a methodology developed for studying and managing complex feedback systems, provides an innovative approach to psychological research and practice. This article examines the application of SD in analyzing psychological processes, enhancing training programs, increasing awareness, manag...
