基于空间的一级和二级视角转换的行为研究及理论综述

摘要： 空间视角转换是从他人视角表征空间关系的能力。本文根据Flavell对空间视角转换能力分出的两个水平，把以往研究的研究方法分为6类：考察一级视角转换能力的可见性任务、数量判断，以及考察二级视角转换能力的识别任务、方向判断、地图巡航、数量判断。随后总结出三种相应的空间视角转换研究的加工理论：，并在以往研究的基础上提出了选取适合的实验任务、开展多个物体的视角转换研究、更多采用虚拟现实呈现刺激材料这3点研究展望。
Abstract: Spatial perspective taking (SPT) is an ability to mentally adopt and represent the spatial relationships from the other’s viewpoints. The purpose of this literature is to review SPT related researches and summaries the relevant theories base on two levels of perspective taking defined by Flavell (1977). (1) For the studies of Level-1 perspective taking, this review divides previous research paradigms into 2 categories: visibility judgment task, quantity judgment task. Visibility task requires participants to judge whether the target is visible for another person. Quantity judgment task asks participants to compare the quantity of targets from their own perspective and the avatar’s. Then judging whether they are the same. (2) For Level-2 perspective taking, this review divides previous research paradigms into 4 categories: recognition task, direction judgment task, map navigation task, quantity judgment task. Recognition task needs participants to imagine a scene at another observer’s position. Direction judgment has three different types of task: pointing task (judgments of relative direction), laterality judgment task, same or different task. Map navigation task demands participants to mentally navigation in a planned map. The quantity judgment task needs participants to answer the quantity of the visible item from avatar’s perspective. In addition, this literature concludes several theories to explain findings on spatial perspective taking. For Level-1 perspective taking, researchers claim that participants would use line-of-sight tracing strategy to perform judgments about the visibility of target. However, it was not clear that how people complete Level-2 perspective taking tasks. Several researches used direction judgment tasks and map navigation tasks found the behavioral performance patterns of Level-2 perspective taking has 2 characteristics: the angular disparity effect, and the back-facing advantage. To explain these effects, the researchers produced three kinds of hypothesis: mental spatial transformation hypothesis, sensorimotor interference hypothesis, spatial compatibility effects hypothesis. (1) Mental spatial transformation hypothesis states that people imagine themselves to transform to a new position, the additional transformation cost resulted the angular disparity effect and back-facing advantage.
