视觉空间关系分为类别与数量两种表征。研究通过控制起参照作用的运动客体消失状态与定位客体出现时间,分析客体运动信息对两种关系判断的影响。结果发现:运动信息在各问隔时间对类别任务影响呈序列排列,运动方向较轨迹信息有优势,轨迹较法线信息有优势;数量表征仅在Ores间隔受运动方向促进,在其他间隔下,三种位置上的判断均无差异。结果表明运动客体类别表征比数量表征更持久;且相埘类别表征,数量判断作为精确距离表征不易受运动方向和轨迹信息影响。
Visuospatial relations can be represented either categorically or coordinately. In the experiment we controlled the state of the moving object' s disappearance and the time of the location object' s appearing, and investigated the impact o( object motion information on the two kinds of proceasing of spatial relations. The results showed the impact of object motion information on the categorical spatial relation processing in three intervals sequentially arranged. Movement direction had an advantage over trajectory information, and trajectory had an advantage over normal information; only under the condition of Oms interval, movement direction could promote coordinate representation. The results suggested the moving object' s categorical representation was more persistent than the coordinate representation, and relatively speaking, movement direction and trajectory information did not influence the coordinate judgments easily.
