参照系冲突对表象更新的影响

Effect of Conflicting Reference Frames on Image Updating

以三维场景图片为学习材料，通过系统操纵参照系之间的冲突，在四个实验中考察了两种不同表象更新任务的参照系冲突效应。结果发现：(1)参照系冲突对以自我为中心的表象更新有显著影响，但对以场景为中心的表象更新影响相对较小，从而导致以自我为中心表象更新相对于以场景为中心的表象更新的优势效应减小直至消失。(2)旋转者身体倾斜与场景倾斜引发的参照系冲突效应具有不对等性：由于整个场景倾斜引发的参照系冲突效应大于由于旋转者身体倾斜引发的参照系冲突效应。(3)与场景同时倾斜的局部空间参照系降低了以场景为中心表象更新任务的参照系冲突效应，但对以自我为中心表象更新任务的参照系冲突效应没有影响。这些结果表明两种表象更新任务具有不同的认知加工机制，并进一步扩展了Presson等提出的空间更新参照系冲突模型。

When an individual moves in an environment， his or her cognitive system must simultaneously update information pertaining to the spatial relations between the environment and his or her body；this is termed as spatial updating. Similarly， when an individual imagines himself or herself or the surrounding objects to be rotating， the representation of the spatial relations between him or her and the surrounding objects will be updated；this is known as image updating. Wraga et al. (2000) found that e
