视觉感知和眼球运动被认为是紧密联系在一起的,不同的领域,从发展心理学认知计算机科学,利用眼动跟踪测量视觉感知。然而,这种普遍观点受到了最近的行为研究的挑战。Spering和卡拉斯可说道审查证据揭示离解感性意识和内容之间的不同类型的眼球运动。这些实验显示情况下,眼球运动比感觉更敏感,或在感知是一个响应时眼球运动遵循另一个方向。许多这样的研究,提出了不同的刺激,每只眼睛(在封面图片所示),但只有一只眼睛的信息是呈现可见的。相反,眼球运动反映访问信息提交给两只眼睛。研究表明认知和与眼部有意识的分离运动是有关联的,这促进我们理解大脑通路的底层视觉和运动有和没有意识。封面图片:Marisa Carrasco/Miriam Spering/UBC Creative Services.


Acting without seeing: eye movements reveal visual processing without awareness


Visual perception and eye movements are considered to be tightly linked. Diverse fields, ranging from developmental psychology to cognition to computer science, utilize eye tracking to measure visual perception. However, this prevailing view has been challenged by recent behavioral studies. On pages 247–258 of this issue, Spering and Carrasco review converging evidence revealing dissociations between the contents of perceptual awareness and different types of eye movements. These experiments have revealed situations in which eye movements are more sensitive than perception, or in which perception follows one response direction while eye movements follow another. In many of these studies, different stimuli are presented to each eye (as illustrated in the cover image), but only the information presented to one eye is rendered visible. Conversely, eye movements reflect access to the information presented to both eyes. The review links awareness to perceptual-eye movement dissociations and furthers our understanding of the brain pathways underlying vision and movement with and without awareness.
