Cognition：揭示人如何记忆和识别场景

人是如何有效的记忆场景和识别场景的呢？过去的研究发现场景识别的视点依赖性，即当再认的场景视角是通过学习的视角呈现时要比新的视角容易辨识。但是在Mou & McNamara2002年的研究中发现了内在参照系的朝向依赖性，即在内在参照系的方向的相对方向判断任务要好于视点方向的任务，实验中内在参照系的方向不同于视点方向。那么内在参照系的朝向依赖性和视点依赖性到底有什么关系呢？

该系列实验研究成功的分离了内在参照系和视点依赖性的效应。在其中一个实验中，被试从视点方向观察场景，但是从内在参照系的方向学习场景 (图 1)。任务是场景再认任务，其中只有场景的一部分呈现(图2)。结果发现当再认场景中的两个物体在内在参照系方向时要比在视点方向的容易辨认，即使把场景旋转到一个新的角度 (图3)。

Abstract

Three experiments investigated the roles of intrinsic directions of a scene and observer’s viewing direction in recognizing the scene. Participants learned the locations of seven objects along an intrinsic direction that was different from their viewing direction and then recognized spatial arrangements of three or six of these objects from different viewpoints. The results showed that triplets with two objects along the intrinsic direction (intrinsic triplets) were
