Abstract: Measuring Imagery is widely used in training. It also a critical step of generating successful training. Three methods of Measuring Imagery are discussed in this paper: the paper and pencil tests, the experiments, and Physiological Psychology Indicators. The paper and pencil tests mainly involve measurement scales, such as the Betts’ Questionnaire upon Mental Imagery, the Vividness of Visual Imagery Questionnaire (VVIQ), the new version of VVIQ (VVIQ2), the Vividness of Movement Imagery Questionnaire (VMIQ), and the revision of VMIQ. For the experimental method, imagery rotation serves as the basic paradigm. As Physiological Psychology Indicators, transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI) are used to observe the vividness of different brain regions during various imagery processes. Each of the three methods has its own advantages and drawbacks that require further improvements.
