摘要
空间关系的理解是概念表征向知觉表征的转化,而空间关系的表达则是知觉表征向概念表征的转化。两种表征的转化以参照系为中介。视觉数量空间关系加工属于知觉表征向概念表征转化的空间关系表达过程。本研究通过控制方向、朝向及距离在启动与探测中的匹配关系,采用三个实验探讨了数量空间关系加工中参照系各参数的表征及其相互作用。结果发现:(1)数量空间关系加工中存在方向表征,一定任务情境下存在朝向表征。(2)距离匹配的促进效果只在启动刺激和探测刺激的方位关系处于参照系同轴时发生。这些结果进而说明,数量空间关系加工中内隐地包含类别空间关系表征,一定任务情境下,可能存在垂直/水平的类别空间关系表征;数量空间关系加工中的距离是联系于参照系轴的表征。
Processing of the visual world around us critically depends upon analysis of spatial relations between objects in scenes and analysis of subcomponents within complex multi-part objects.Spatial relations between objects can be represented either categorically or coordinately.The research results of the separation of processing two kinds of spatial relations are unstable and limited to the level at which two types of processing can affect each other.The analysis was not conducted on whether the processing of spatial relations would implicitly include spatial relations to another.The inevitable interference and interaction with each other in the two tasks of relations existed in previous studies,and the difficulties in the two tasks are different.All of these factors,therefore,could influence the analysis of the relations between the two kinds of processing of spatial relations.Spatial relations are not only required by the visual analysis and the formation of a perceptual representation,but also,they form a conceptual representation due to the exchange.The understanding of spatial relations is the transformation of conceptual representation into the perceptual representation,while the expression of spatial relations is the transformation of perceptual representation into the conceptual representation.The reference system links the perceptual representation and the conceptual representation.The reference system is characterized as a three dimensional axial system,which is defined by a number of parameters,including origin,orientation,direction,spatial templates,and distance.Reference frame can be free to adjust each parameter,and move around the space as with any object,therefore,the reference frame is of a good flexibility.The processing of visuospatial relations is the expression of spatial relations,which is the transformation of perceptual representation into the conceptual representation.No studies by now,however,have explored the representation of reference frame and parameters in the processing of visuospatia
