分散空间注意条件下客体特征一致性对视觉特征错觉性结合的影响

本研究通过设置对空间注意资源的分配实施强行操作的情形下，探讨了主、次作业客体形状一致性和次作业客体间距对乏空间注意区次作业客体颜色、形状特征的检测及对特征错觉性结合的影响。实验结果表明：（１）分散空间注意使次作业区域注意减弱，对客体及其颜色和形状特征的识别均产生明显影响．而且对形状的影响又大于颜色；（２）特征错觉性结合率，主、次作业客体形状一致时比客体形状不一致时明显增大；（３）次作业客体间距对特征错觉性结合率无明显影响，但客体形状一致性和客体间距之间存在明显交互作用．

THE EFFECTS OF IDENTITY OF OBJECTFEATURES ON FEATURE ILLUSORY CONJUNCTION IN DIVERTING VISUAL SPATIAL ATTENTION

The present study was conducted to investigatethe effect of object shape identity and object intervalson the detecting of object features and feature illusoryconjUnction in the conditions of diverting visual spatialattention. The fOllowing were our conclusions: 1 )There were significant effects of diverting spatial attention on the detecting of object features of sub tasks. The effect of shape was greater than that ofcolor. 2) When object shapes of tasks and sub-taskswere the same, the illusion conjunction of object feature was greater than when they were different. 3)There were not significant effects of the interval offeature illusion conjunction, but there were interactioneffects of the shape identity and the object interval onillusion conjunction.
