The present study focuses on two factors that may influence the accuracy and precision of a judge's evaluation of the angular deviation error in "inverted cross" (angle of the arms away from the horizontal axis). 16 Greek judges of competitive gymnastics participated in an evaluation of the magnitude of the error in the skill. Photographs of the performance of 8 gymnasts were shown to the judges in triplicates in random order from three angles of observation (0 degrees, 45 degrees, and 90 degrees) on a computer screen. The precision in the judges' judgments was best at the 45 degrees angle of observation and at angular deviations of 16 degrees to 30 degrees. Accuracy was influenced both by the judge's angle of observation and the gymnast's angular deviation, as well as by the interaction. Overall, judges may need to improve their ability to evaluate performance through training. Training may incorporate a variety of exercises in judging the inverted cross through augmented feedback of knowledge of results.
本研究关注两个可能影响裁判评估“倒十字”（手臂与水平轴的夹角）角度偏差误差准确性和精度的因素。16 名希腊竞技体操裁判参与了对技能误差幅度的评估。8 名体操运动员的表演照片以随机顺序从三个观察角度（0 度、45 度和 90 度）在计算机屏幕上以三倍的方式呈现给裁判。在 45 度观察角度和 16 度至 30 度的角度偏差下，裁判的判断精度最佳。准确性受到裁判观察角度、体操运动员的角度偏差以及相互作用的影响。总体而言，裁判可能需要通过培训来提高他们的表现评估能力。培训可以通过知识结果的增强反馈来评估倒十字，包括各种评估练习。
