知觉多稳态:透视脑功能失调的多面窗口
Perceptual multistability: a multifaceted window into brain dysfunctions
一篇发表于 Trends in Cognitive Sciences 的综述提出,知觉多稳态可作为理解多种认知功能与功能障碍的窗口。依据摘要,作者整合两类计算精神病学路径:把知觉视为无意识推断的贝叶斯建模,以及把知觉切换视为内部动作的主动信息寻求视角(如强化学习)。
综述梳理知觉多稳态在临床与非临床人群中的时间动态和信息整合差异,并对比贝叶斯建模与强化学习两种计算精神病学路径。
Perceptual multistability, observed across species and sensory modalities, offers valuable insights into numerous cognitive functions and dysfunctions. For instance, differences in temporal dynamics and information integration during percept formation often distinguish clinical from nonclinical populations. Computational psychiatry can elucidate these variations through two primary approaches: (i) Bayesian modeling, which treats perception as an unconscious inference, and (ii) an active, information-seeking perspective (e.g., reinforcement learning), which frames perceptual switches as internal actions. Our synthesis aims to leverage multistability to bridge these computational psychiatry subfields, linking human and animal studies as well as connecting behavior to underlying neural mechanisms. Perceptual multistability emerges as a promising noninvasive tool for clinical applications, facilitating translational research and enhancing our mechanistic understanding of cognitive processes and their impairments.
