摘　　要：以往研究发现类别空间关系表征具有左半球激活优势,但在行为表现中是否存在对侧化的右侧化优势尚且不明确。本研究采用两个被试内实验,探讨空间记忆的行为表现是否具有右侧化优势以及这种优势是否受威胁情境的影响。实验1被试学习完一幅模拟地图中物体位置关系后进行相对位置判断任务,结果发现了显著的空间行为反应右侧化优势。实验2使被试在威胁情境中完成相同任务,发现右侧化优势消失。实验表明类别性空间记忆的行为表现具有右侧化优势,且具有情境不稳定性,这为空间记忆的偏侧化研究提供了一定的行为实验证据。Previous studies indicated that the categorical spatial memory had an activating advantage of left hemisphere. However,the behavioral evidence of right advantage in categorical spatial memory has not been found according to the lateralization. The present study included two within-subject experiments aiming at exploring whether the categorical spatial memory had a right advantage of behavioral performance and its stability in threatened situation. Participants of experiment 1 finished a relevant judgment of direction task after learned a mimetic map. It turn out a significant right advantage of spatial memory. The participants of experiment 2 finished the same task under a threatened situation. The right advantage of spatial performance disappeared. The results indicate that categorical spatial memory has a right advantage of behavioral performance and that it is unstable in the threatened situation. The current study provides a certain behavioral evidence of lateralization in spatial memory.
