空间再定向中的线索利用

The Use of Cues in Spatial Reorientation

摘要: 自然界中存在着丰富的空间线索，如何利用有效的空间线索进行再定向一直是研究的热点问题。近几年关于再定向的研究发现，人类对空间线索的利用受到年龄、过去经验、主动性等因素的影响。一些研究发现，在多种线索存在的情况下，人类能够以贝叶斯最优的方式对不同的线索进行整合，提高再定向的精度和准确度；线索发生冲突时，人类对线索的选择取决于线索相对权重大小。本文通过对近几年再定向研究的总结，阐明再定向中的线索利用机制，为后续的研究做铺垫。

Abstract: There are abundant spatial cues in nature. How to use the effective spatial cues for redirection has always been a hot research issue. Recent studies on redirection have found that human’s use of spatial cues is influenced by factors such as age, past experience and initiative. Some studies have found that in the presence of multiple cues, humans can integrate different cues in a Bayesian optimal way to improve the accuracy and accuracy of redirection. When the cue conflicts, the choice of the cue depends on the relative weight of the cue. In this paper, a summary of redirection research in recent years is made to clarify the mechanism of cue utilization in redirection, which will pave the way for further research.
