视觉统计概要表征的机制

Mechanism of Visual Statistical Summary Representations

Abstracts

尽管感觉登记是容量无限的,但不意味着视觉系统无需高效地处理我们日常面对的海量的视觉信息,统计概要表征便是一种高效的信息加工过程,当呈现由多个视觉刺激构成的集合,视觉系统可以快速提取集合的平均属性等统计概要信息。统计概要表征是理解神经计算过程的重要心理过程。目前有很多研究揭示了这一过程的某些认知机制,如自动性加工机制,不同水平或特征间的特异性或通用性的机制。然而仅有少量研究关注其神经机制,未来需要更多的研究采用神经科学技术手段直接考察统计概要表征的神经机制。

[英文摘要]Despite the unlimited capacity of sensory registration, visual system can still provide an efficient summary of a cluttered scene, representing the statistical properties of multiple objects rather than forming detailed representations of individual objects. There is growing interest in the behavioral study of statistical summary representations (SSRs), especially in the exploring of their automatic mechanism as well as the domain-general or domain specific ensemble mechanism. However, the neural underpinnings of SSRs have received far less attention. Future work on SSRs may use neuroimaging methods to investigate their neural substrates directly, which is also important for understanding neural computation.
