对环境统计结构的敏感性是感知的关键，这一概念最近引起了相当大的关注。在这里，我们在听力的背景下研究这个问题。在之前的工作（Sohoglu & Chait）的基础上，刺激是由多个（多达14个）同时存在的声源（“听觉对象”）组成的人工“声音场景”，这些声源由音调-音调序列组成，每个声源都有不同的频率和振幅调制模式。序列要么是暂时规则的，要么是随机的。我们表明，当场景源具有时间规则波动模式的特征时，听者检测源突然出现或消失的能力得到了促进。变化源的模式以及背景（不变）源的模式分别对这种效应作出贡献。值得注意的是，听众从规律中受益，即使他们没有意识到这一点。这些发现表明，对复杂声学场景的感知依赖于从每个场景源自动提取的规律的详细表示的可用性。
The notion that sensitivity to the statistical structure of the environment is pivotal to perception has recently garnered considerable attention. Here we investigated this issue in the context of hearing. Building on previous work (Sohoglu & Chait, ), stimuli were artificial ‘sound-scapes’ populated by multiple (up to 14) simultaneous sources (‘auditory objects’) comprised of tone-pip sequences, each with a distinct frequency and pattern of amplitude modulation. Sequences were either temporally regular or random.We show that listeners’ ability to detect abrupt appearance or disappearance of a source is facilitated when scene sources were characterized by a temporally regular fluctuation pattern. The patterning of the changing source as well as that of the background (non-changing) sources contribute independently to this effect. Remarkably, listeners benefit from regularity even when they are not consciously aware of it. These findings establish that perception of complex acoustic scenes relies on the availability of detailed representations of the regularities automatically extracted from each scene source.
