This study aimed to investigate the construct of external visual imagery (EVI) internal visual imagery (IVI) by comparing the athletes' imagery ability with their levels of skill and types of sports.
Seventy-two young athletes in open ( = 45) or closed ( = 27) sports and with different skill levels completed 2 custom-designed tasks. The EVI task involved the subject generating and visualizing the rotated images of different body parts, whereas the IVI task involved the subject visualizing himself or herself performing specific movements.
The significant Skill-Level × Sport Type interactions for the EVI task revealed that participants who specialized in open sports and had higher skill-levels had a higher accuracy rate as compared to the other subgroups. For the IVI task, the differences between the groups were less clear: those with higher skill-levels or open sports had a higher accuracy rate than those with lower skill-levels or closed sports.
EVI involves the visualization of others and the environment, and would be relevant to higher skill-level athletes who engage in open sports. IVI, in contrast, tends to be more self-oriented and would be relevant for utilization by higher skill-level athletes regardless of sport type.
本研究旨在通过比较运动员的表象能力与其技能水平和运动类型，来探究外部视觉表象（EVI）和内部视觉表象（IVI）的结构。
72名从事开放性运动（n = 45）或封闭性运动（n = 27）且技能水平不同的年轻运动员完成了两项定制任务。EVI任务要求受试者生成并想象不同身体部位的旋转图像，而IVI任务要求受试者想象自己进行特定动作。
EVI任务中显著的技能水平×运动类型交互作用表明，与其他亚组相比，从事开放性运动且技能水平较高的参与者准确率更高。对于IVI任务，组间差异不太明显：技能水平较高或从事开放性运动的参与者比技能水平较低或从事封闭性运动的参与者准确率更高。
EVI涉及对他人和环境的想象，与从事开放性运动的高技能水平运动员相关。相比之下，IVI往往更以自我为导向，无论运动类型如何，都与高技能水平运动员的使用相关。
