Neural mechanisms of perceiving dynamic real-world environments

点击翻译按钮获取中文摘要

People are surrounded by a complex dynamic world characterized by a multitude of sights and sounds. When hiking in the woods, for instance, they may see the path outlined in the undergrowth ahead, or perhaps they may spot some deer; they may hear a stream purling nearby or the treetops swaying in the wind. Stepping out of a streetcar onto a busy city street, on the other hand, people may see tall buildings, pedestrians on the sidewalks or cars in the street; they may hear engine noises or a police siren in the distance. The particular environment contributes to shaping people’s behaviour for tasks such as navigation, threat avoidance, visual search or memory encoding.
