记忆和物体识别的传统研究涉及在单一感觉模态内呈现的物体（即，纯视觉或纯听觉对象）。然而，在自然环境中，物体通常以多感官的方式进行评估和处理。这就引出了这样一个问题，即如何创造并利用来自不同感官的联合收割机信息的物体表征。在这里，我们回顾的研究表明，一个单一的多感官暴露可以影响记忆的视觉和听觉对象。在一个新的/旧的对象的歧视任务，最初提出的任务无关的刺激，在另一种意义上的对象更好地记住单独提出的刺激相比，最显着的是当两个刺激语义一致。大脑在刺激开始后的第一个100 ms内区分这两种类型的对象表征，表明大脑基于其初始呈现上下文的性质对对象/事件进行早期“标记”。有趣的是，支持改进的物体识别的特定大脑网络基于各种因素而变化，包括初始多感官呈现的有效性和与任务相关的感觉。我们指定的必要条件，多感官的背景下，以提高物体的歧视，以下单次曝光，和个体差异，存在这些改进。我们的结果揭示了记忆如何作用于物体表征的多感官本质，以及大脑如何存储和检索物体的记忆。
Traditional studies of memory and object recognition involved objects presented within a single sensory modality (i.e., purely visual or purely auditory objects). However, in naturalistic settings, objects are often evaluated and processed in a multisensory manner. This begets the question of how object representations that combine information from the different senses are created and utilised by memory functions. Here we review research that has demonstrated that a single multisensory exposure can influence memory for both visual and auditory objects. In an old/new object discrimination task, objects that were presented initially with a task-irrelevant stimulus in another sense were better remembered compared to stimuli presented alone, most notably when the two stimuli were semantically congruent. The brain discriminates between these two types of object representations within the first 100ms post-stimulus onset, indicating early “tagging” of objects/events by the brain based on the nature of their initial presentation context. Interestingly, the specific brain networks supporting the improved object recognition vary based on a variety of factors, including the effectiveness of the initial multisensory presentation and the sense that is task-relevant. We specify the requisite conditions for multisensory contexts to improve object discrimination following single exposures, and the individual differences that exist with respect to these improvements. Our results shed light onto how memory operates on the multisensory nature of object representations as well as how the brain stores and retrieves memories of objects.
