Abstract: This study examined affect of the observation angle, the color and form similarity of the object target stimulus on, the perspective of the beeline two stimulus on and the level, and the distance between two stimulus in three-dimensional spatial category relations judgment missions by using the target-category paradigm. Two experiments were designed to test the score of subjects under different conditions in three-dimensional spatial category relations judgment missions, adopting category-target paradigm. The study suggested that due to the change observation angle in three-dimensional spatial category relations judgment, the more information subjects got, the more efficiency of judgment of categorical spatial relations was. The similar background was difficult to judgment with more mistakes and more time to react: the more similar of the color of backdrop, the more difficult to judgment. Judgment of categorical spatial relations was also affected by perspective of targets (the perspective of the beeline two stimuli on and the horizontal line): when the perspective of targets was 0°or 90°, it cost subjects more time to judge with more errors.

Key words: categorical spatial relation, visual space attention, observation Angle, similarity of background

摘要： 研究采用目标-类别范式，通过两个实验探讨三维情境中观察角度、靶刺激所在物体颜色和形状的相似性、靶刺激空间距离及离开水平方向的角度对类别空间关系加工的影响。研究结果表明，在不同的观察角度，获得物体的信息越多，类别空间关系判断越容易；背景颜色相似性高类别空间关系加工的效率较低；两个靶刺激之间的距离对于类别空间判断影响较小；靶刺激观察角度为竖直和水平方向时，类别空间关系判断的效率较低。
