自我优势效应对远近空间中空间参照框架的影响

联合颜色−标签匹配任务和空间参照框架判断任务，考察自我优势效应对远近空间中空间参照框架表征的影响。颜色−标签匹配任务要求被试对颜色（黑色/白色叉子）与标签词（自我/他人）之间建立稳定的联结，被试随机分为自我联结组和他人联结组，两组被试均需在远近空间中完成空间参照表征任务。结果发现：（1）与他人联结组相比，自我联结组表现出显著的自我优势效应；（2）自我优势效应对空间参照表征的影响仅体现在近处空间且对自我中心表征任务的影响更大。研究表明，自我优势效应优先影响近处空间表征，表现出近处优先性。

The Effect of Self-Prioritization on Reference Frame in Near and Far Spaces

Previous studies showed that the self-prioritization effect (SPE) showed a self-bias both on the processing of egocentric representation and near-space representation. However, little is known about how the brain balances the representation of spatial reference frames and spatial locations in depth. Therefore, the present study adopted the label-color matching task (i.e., self-/stranger-association) to establish the SPE, combined with the spatial reference task, to examine whether the SPE prefers to process the near-space representation or the egocentric representation. Participants were randomly assigned to the self-association group and the stranger-association group. Both groups were required to accomplish the spatial reference task in near and far spaces. The results found that: 1) there was a significant SPE in the self-association group compared with the stranger-association group; 2) the effect of SPE on spatial reference representation only manifested in near space and had a greater impact on the egocentric representation. These findings indicate that SPE may show a prior entry effect for near-space representation when the brain processes the conflict between the dorsal and ventral streams simultaneously.
