确定记忆是如何组织的仍然是心理学中的一个基本问题。以往的研究表明，视觉短时记忆是根据起源的对象来组织的，参与者更善于从同一对象提取多条信息，而不是从不同的对象提取。然而，目前还不清楚类似的记忆结构是否适用于其他形式，如试听。在听觉领域类似的条件下，我们发现对声音的短期记忆也可以根据对象来组织，在由两个在空间和时间上重叠的复杂声音定义的听觉场景中，相同对象的优势被展示出来。我们的结果支持听觉对象的概念，除了继续识别视觉和听觉领域中类似的加工限制。识别与通道无关的记忆组织原则，如基于对象的编码，提出了人类处理系统记忆多通道经验的可能机制。
Identifying how memories are organized remains a fundamental issue in psychology. Previous work has shown that visual short-term memory is organized according to the object of origin, with participants being better at retrieving multiple pieces of information from the same object than from different objects. However, it is not yet clear whether similar memory structures are employed for other modalities, such as audition. Under analogous conditions in the auditory domain, we found that short-term memories for sound can also be organized according to object, with a same-object advantage being demonstrated for the retrieval of information in an auditory scene defined by two complex sounds overlapping in both space and time. Our results provide support for the notion of an auditory object, in addition to the continued identification of similar processing constraints across visual and auditory domains. The identification of modality-independent organizational principles of memory, such as object-based coding, suggests possible mechanisms by which the human processing system remembers multimodal experiences.
