一个场景的视图通常被认为包含了可能已经出现在该视图的实际边界之外的信息，这被称为边界扩展。视图的特性（例如，场景或非场景;特写或广角;无论对象是裁剪的、静态的还是运动的、情绪中性的还是情绪激动的），显示（例如，孔径形状和尺寸;目标持续时间;保留间隔;存储器的探测是否涉及放大/缩小或物理距离的改变），以及观察者（例如，注意力分配;老化;计划的注视、注视方向和眼球运动;单眼或双眼观察;先前暴露;神经学相关性）影响边界延伸。边界扩展的建议机制（感知，记忆或运动图式;扩展规范化;注意力选择;源监测中的错误）进行了讨论，以及边界扩展与其他认知过程（例如，代表性的势头;记住的距离和记住的大小;非模态完成;跨眼动记忆）进行了简要讨论。
A view of a scene is often remembered as containing information that might have been present just beyond the actual boundaries of that view, and this is referred to as boundary extension. Characteristics of the view (e.g., scene or nonscene; close-up or wide-angle; whether objects are cropped, static, or in motion, emotionally neutral or emotionally charged), display (e.g., aperture shape and size; target duration; retention interval; whether probes of memory involve magnification/minification or change in physical distance), and observer (e.g., allocation of attention; age; planned fixation, gaze direction, and eye movements; monocular or binocular viewing; prior exposure; neurological correlates) that influence boundary extension are reviewed. Proposed mechanisms of boundary extension (perceptual, memory, or motion schema; extension-normalization; attentional selection; errors in source monitoring) are discussed, and possible relationships of boundary extension to other cognitive processes (e.g., representational momentum; remembered distance and remembered size; amodal completion; transsaccadic memory) are briefly addressed.
