To navigate through their immediate environment humans process scene information rapidly. How does the cascade of neural processing elicited by scene viewing to facilitate navigational planning unfold over time? To investigate, we recorded human brain responses to visual scenes with electroencephalography and related those to computational models that operationalize three aspects of scene processing (2D, 3D, and semantic information), as well as to a behavioral model capturing navigational affordances. We found a temporal processing hierarchy: navigational affordance is processed later than the other scene features (2D, 3D, and semantic) investigated. This reveals the temporal order with which the human brain computes complex scene information and suggests that the brain leverages these pieces of information to plan navigation.
人类在其周围环境中导航时会快速处理场景信息。那么，场景观看引发的神经处理级联反应是如何随着时间推移而促进导航规划的呢？为了研究这个问题，我们使用脑电图记录了人类对视觉场景的大脑反应，并将这些反应与可操作化场景处理三个方面（二维、三维和语义信息）的计算模型以及捕捉导航功能的行为模型相关联。我们发现了一个时间处理层次结构：导航功能比其他研究的场景特征（二维、三维和语义）出现得更晚。这揭示了大脑计算复杂场景信息的时间顺序，并表明大脑利用这些信息来规划导航。
