Mental rotation cognitive tasks based on motor imagery (MI) have excellent predictability for individual's motor imagery ability. In order to explore the relationship between motor imagery and behavioral data, in this study, we asked 10 right-handed male subjects to participate in the experiments of mental rotation tasks based on corresponding body parts pictures, and we therefore obtained the behavioral effects according to their reaction time (RT) and accuracy (ACC). Later on, we performed Pearson correlation analysis between the behavioral data and the scores of the Movement Imagery Questionnaire-Revised(MIQ-R). For each subject, the results showed significant angular and body location effect in the process of mental rotation. For all subjects, the results showed that there were correlations between the behavioral data and the scores of MIQ-R. Subjects who needed the longer reaction time represented lower motor imagery abilities in the same test, and vice versa. This research laid the foundation for the further study on brain electrophysiology in the process of mental rotation based on MI.
已有研究认为，运动想象心理旋转认知任务对个体的运动想象能力有较好的预测度。为探索运动想象能力与行为学数据之间的关联性，本研究对 10 名右利手男性受试者开展了身体部位相关图片的心理旋转任务试验，根据其反应时和正确率得出行为学效应，并将行为学数据与运动想象量表评分进行皮尔逊相关性分析。研究结果表明，对于单一受试者来说，在心理旋转过程中存在明显的角度效应、身体部位效应；对于所有受试者，行为学数据与运动想象量表评分呈相关性，研究结果表明受试者反应时越长，运动想象能力越差，反之同理。本研究可为后期开展运动想象心理旋转过程中的脑电生理学研究奠定前期基础。.
