视觉空间关系判断的分离与协同

采用任务表征相互影响范式,通过三个实验探讨了类别空间关系判断和数量空间关系判断的加工特性和相互关系.结果表明:(1)先行类别关系启动有利于数量空间关系判断,对类别空间关系判断没有影响;先行数量关系启动对两个判断任务均无影响.(2)先行类别关系干扰降低两个空间关系判断的绩效,先行数量关系干扰对两个空间关系判断没有影响.(3)先行类别关系对空间关系判断的启动和干扰效应不局限于特定条件,具有普遍性.研究提示,右脑为优势半球的数量关系加工以左脑为优势半球的类别关系加工为基础,支持视觉空间认知加工既分离又协同的观点.

Dissociation and Cooperation in Visuospatial Relations Judgment

Three experiments were designed,to test the connection of two spatial relations judgment with the paradigm of tasks- interaction-with-others. Simple dot-line stimuli spatial relation tasks and ecological dot-figure tasks were conducted. The results of Experiment 1 and Experiment 2 showed that a categorical prime could speed upthe processing of a coordinate task and did not affect categorical judgment. A categorical interference could both cut down the performance of the categorical and coordinate processing. There was an absence of priming and interference effects in the two tasks with a previous coordinate prime and a coordinate interference respectively. The results of Experiment 3 implied that the effect of Experiment 1 and Experiment 2 was a relatively general phenomenon. The research suggested that there were dissociation and cooperation in visuospatial relations judgment.
