The proposed project will investigate the decomposition of auditory scenes into single objects, such as speech and background music in a movie. Different acoustic sources show different sound emission patterns, and the resulting regular patterns within concurrent sounds are possible cues for source distinction. Accordingly, it has been suggested that object formation is supported by pre-attentive regularity extraction in the auditory system. This hypothesis will, for the first time, be tested in the proposed project. In this novel approach, previous findings on regularity extraction and in auditory object formation will be combined to test functional relations between the two. Six experiments will be conducted using behavioural responses and event-related potentials (ERPs) in healthy adult participants and ERPs in newborn infants. Key objectives are to reveal the conditions under which regularity extraction contributes to object formation, to evaluate the interaction of regularity-based object formation with other grouping principles (such as Gestalt rules and instantaneous harmonicity), and to determine which of these mechanisms are already present at birth. The project will advance our understanding of auditory perception in natural situations, and will be relevant for applications such as hearing aids and communication devices.

该项目将研究将听觉场景分解为单个对象，例如电影中的语音和背景音乐。不同的声源表现出不同的声音发射模式，并在并发的声音中产生的规则模式可能是源区分的线索。因此，已经提出，对象形成由听觉系统中的前注意规则性提取支持。这一假设将首次在拟议项目中得到检验。在这种新的方法中，以前的研究结果的规律性提取和听觉对象的形成将被结合起来，以测试两者之间的功能关系。将使用健康成人参与者的行为反应和事件相关电位（ERP）以及新生儿的ERP进行六项实验。主要目标是揭示条件下的规则提取有助于对象的形成，以评估的相互作用的规则为基础的对象的形成与其他分组原则（如完形规则和瞬时和谐），并确定这些机制已经存在于出生。该项目将促进我们对自然情况下听觉感知的理解，并将与助听器和通信设备等应用相关。
