对象到场景绑定假设坚持视觉对象表示被存储为较大场景表示或场景上下文的一部分，并且场景上下文便于对象表示的检索（参见，例如，Hollingworth，Journal of Experimental Psychology：Learning，Memory and Cognition，32，58-69，2006）。支持这一假设的数据来自使用有意记忆任务。在本研究中，我们研究是否场景上下文总是有利于检索的视觉对象表示。在两个实验中，我们研究了场景上下文是否有利于检索的对象表示，使用一个新的范例，其中一个内存任务被附加到一个重复闪烁变化检测任务。结果表明，在正常的场景观察中，许多同时出现的物体，只有当观察者需要为一项任务保留大量信息时（即，一个有意识的记忆任务）。
An object-to-scene binding hypothesis maintains that visual object representations are stored as part of a larger scene representation or scene context, and that scene context facilitates retrieval of object representations (see, e.g., Hollingworth, Journal of Experimental Psychology: Learning, Memory and Cognition, 32, 58-69, 2006). Support for this hypothesis comes from data using an intentional memory task. In the present study, we examined whether scene context always facilitates retrieval of visual object representations. In two experiments, we investigated whether the scene context facilitates retrieval of object representations, using a new paradigm in which a memory task is appended to a repeated-flicker change detection task. Results indicated that in normal scene viewing, in which many simultaneous objects appear, scene context facilitation of the retrieval of object representations-henceforth termed object-to-scene binding-occurred only when the observer was required to retain much information for a task (i.e., an intentional memory task).
