客体投影方式对空间问题解决和再认的影响

通过设置四种实验条件，旨在阐明空间问题解决和再认的水平是如何受到客体不同投影方式的影响。除进一步支持了正投影问题的解决是以一个具有三维结构特性的心理表征为基础而并非是对二维正投影信息进行了充分识别的观点外，研究结果还表明：（１）这个具有客体三维结构特性的心理表征是建构于对正投影问题解决而非轴测投影图的再认过程中；（２）正投影问题解决的复杂性显著地高于轴测投影图问题解决而且一个建构于正投影问题解决中

THE EFFECT OF TYPES OF PROJECTION OF OBJECTS ON SPATIAL PROBLEM SOLVING AND RECOGNITION

Four experimental conditions including orhographic problem solving followed by isometric and orthographic recognition, isometric problem solving followed by recognition of isometric views and orthographic recognition, were used to study how performances on spatial problem solving and recognition were influenced by the types of projection of visual objects used in each task. Besides the fact that had further supported the claim that orthographic problem solving was accomplished by constructing a mental representation of three-dimensional object and ruled out the alterative explanation of adequacy of encoding of two-dimensional projection of objects, the results also indicated: ( 1) Mental representation of three-dimensional object was constructed in the course of problem solving based on two-dimensional information, rather than in recognition of isometric view of object; (2) The complexity of orthographic problem solving was significantly higher than that of isometric problem solving; furthermore, a constructed mental representation was advanatageous only for the sequent recognition of isometric views of three-dimensional objects, but not for orthographic recognition; (3) The constructed mental representation had the properties that made spatial information more easily organized and stored and less fragile than two-dimensional infromational representation. The findings would be of significance not only to further study on the characters of spatial representation in problem solving and recognition, but also in finding further evidence concerning implicit memory for object structure.
