基于线索的视觉空间关系判断

融合视觉空间关系识别中的类别关系判断和数量（坐标）关系判断，通过4个实验探讨了影响视觉空间关系判断的线索性方面的因素。结果表明：视觉空间关系判断受角度影响不明显；单线索条件下刺激越靠近可视线索，判断绩效越好；多线索条件下在不显著延长反应时间的情况下有助于提高视觉空间关系判断的正确率；另外不均匀条件（边界线有一定斜率）不利于视觉空间关系的判断。

VISUOSPATIAL RELATIONS JUDGMENT BASED ON CLUE

It has been hypothesized that there are two different kinds of spatial-relation representations in the human brain: categorical and coordinate spatial relations representations. With integrating categorical spatial relation and metric/coordinate spatial relation, this study examined the visuospatial relations judgment based on clue. Experiment 1 was conducted to test the effect from different degrees on visuospatial relations judgment. It was found that the effect was not significant. The results of Experiment 2 with one clue showed that when target was input of scope made of central clue and borderline, the judgment was faster than target was output of the scope. The input/output effect was not confirmed by experiment 3&4, which were carried out with double clue slope clue (k=0.38) on visuospatial relations judgment.
