多参照系条件下信息获取方式对绝对方位判断的影响

How Information Presentation Affect Absolute Direction Judgments Based on Spatial Reference Frames

把参照系整合基础上的绝对方位判断分解成路径获取过程（目标位置信息）、自身定向过程（前行方向信息）和物体定位过程（目标物体相对于参照物体的方位信息），系统地考察了多参照系条件下信息获取方式对该任务的影响。研究以视觉形式呈现空间信息，实验1a和1b的任务中均包括上述三个过程，前者以地图的形式呈现前行方向信息、后者以语词的形式直接呈现前行方向信息；实验2有两个任务，分别独立于路径描述（定位后判断）和自身定位（定向后判断）。所有任务均为目标位置（R0°-前、R45°-左前／右前、R90°-左／右、R135°-左后／右后，R180°-后）X前行方向（北、东南西、斜方向）的组内设计，因变量为正确率和判断时间为主，共有64名大学生被试（男女各半）参与实验。发现：0°和180°位置优势效应、朝北优势效应在所有任务中都很明显；实验1和定向后判断任务中存在正方向R90°位置优势效实；定位后判断时间短于定向后判断时间，但总体所用时间上没有差异。结合信息获取的方式和可能使用到的判断策略，从绝对方位判断的认知结构等方面展开了讨论。

People cannot maintain his/her orientation or specify a spatial location without using at least basically， a frame of reference. Egocentric reference frame and allocentric/exocentric reference frame are used most coordinately and frequently for the purpose of successful navigation. Many recent studies have focused on how and why misalignment and target position relative to reference object affect cardinal direction judgments. In these studies， participants see a north-up map indicating one observer’s heading relative to a ground garget， which was presented as camera scene with corresponding forward view. A typical task is to determine the cardinal direction between two objects in the scene. They have reported 0°(up)and 180° (bottom) advantage effect and mismatch effect. However these studies have little consideration about information processing and many of them only use cardinal direction task. In the current study， we defined three types of heading (heading identifying)， and determining the direction of the target object in the scene (direction determining). We aimed to investigate whether different component’s processing could influence the aforementioned effects on absolute direction judgment. Different information presenting orders were used in corresponding experiments.
