掩蔽刺激的空间参考框架对视觉表象旋转的影响

本实验通过将具有参考框架信息的前置刺激改为掩蔽刺激，进一步探讨参考框架的变化和表象旋转的过程。结果表明：１、因掩蔽刺激而引起的主观参考框架的产生是瞬间完成的，而不是由原先直立的参考框架经过连续旋转后形成的。２、显示了倾斜字母的加工不完全是整体表象的线性旋转过程，而可能是整字一成分的混合加工过程。

THE EFFECT OF REFERENCE FRAME ON MENTAL ROTATION

With the change of the preceding stimuli intomarking stimuli, the present research further investigated into the nature of internal reference frame andthe process of mental rotation. The results showedthat 1) The effect of the reference frame caused bymarking stimuli was immediate, and it was not similarto the process of physical rotation. 2) The processingof misoriented letters was hot analogous with thephysical rotation in which the whole image of a letterwas rotated; but the processing possibly tallied withthe whole --component mixed model.
