The degree and direction of rotation greatly affect the students' performance ; the passing rate of 90 degree items is better than that of 180 degree items , the passing rate of 180 degree items is better than that of 360 degree items, and the passing rate of right-rotation items is better than that of left-rotation items. Furthermore, handedness also affects the students' performance; the performance of right-handedness is better than that of left-handedness; right-handed students show an significant advantage over left-handed students on the items of left rotation, but no significant advantage on the items of right rotation.

四、空间旋转游戏经验的多寡，与学童的测验表现有著高度的正相关；而二度空间旋转的表现显著优於三度空间旋转；又旋转角度与旋转方向均显著的影响学童的表现，旋转角度愈大，答对率愈低，向右旋转试题优於向左旋转试题；另外，手利亦显著影响学童的表现，右手利优於左手利，右手利学童在向左旋转的测验表现上，显著优於左手利学童；但在向右旋转试题上，则无显著差异。。

Using this method, the controller design for performance and robustness can be designed separately, which has the potential to overcome the conflict between performance and robustness in the traditional feedback framework. Third, to make the vehicle meet the performance index in full flight envelop, a H∞ gain-scheduled controller based on Linear Varying Parameter system are designed. A LPV plant with a linear fractional dependent variable can be represented by upper LFT (Linear Fractional Transformation) interconnection.
