The ability to generate and control images is an important key to the effectiveness of imagery interventions. However, not until recent years has, the method of developing imagery ability been gradually established and confirmed. This article will describe the theory, application and related research findings of three techniques of layered stimulus response training (LSRT), observation and PETTLEP imagery. It is hoped that by means of the techniques introduction and the latest research results, it will be used as a guide for the follow-up practitioners to promote the user's imagery ability, and the researchers can continue to explore more effective ways to improve imagery ability. Through it, we hope to let the imagery interventions much more achieve the desired goal.
