Is boundary extension (false memory beyond the edges of the view; Intraub & Richardson, 1989) determined solely by the schematic structure of the view or does the quality of the pictorial information impact this error? To examine this color photograph or line-drawing versions of 12 multi-object scenes (Experiment 1: N=64) and 16 single-object scenes (Experiment 2: N=64) were presented for 14-s each. At test, the same pictures were each rated as being the "same", "closer-up" or "farther away" (5-pt scale). Although the layout, the scope of the view, the distance of the main objects to the edges, the background space and the gist of the scenes were held constant, line-drawings yielded greater boundary extension than did their photographic counterparts for multi-object (Experiment 1) and single-object (Experiment 2) scenes. Results are discussed in the context of the multisource model and its implications for the study of scene perception and memory.
边界扩展（超出视野边缘的错误记忆；Intraub和Richardson，1989）是仅由视野的示意性结构决定的，还是图像信息的质量会影响这种错误呢？为了研究这一问题，分别向被试呈现了12个多物体场景的彩色照片或线条画版本（实验1：N = 64）以及16个单物体场景的彩色照片或线条画版本（实验2：N = 64），每个版本呈现14秒。在测试阶段，要求被试将相同的图片分别评定为“相同”、“更近特写”或“更远”（5点量表）。尽管场景的布局、视野范围、主要物体到边缘的距离、背景空间以及场景要点均保持不变，但对于多物体场景（实验1）和单物体场景（实验2），线条画产生的边界扩展比其对应的彩色照片更大。研究结果将在多源模型的背景下进行讨论，以及其对场景感知和记忆研究的启示。
