场景内容被认为可以快速有效地处理，从而影响后续的视觉探索。在对自然场景进行无任务视觉探索期间，场景内容是否会影响空间注意力？如果是这样，这种偏见是由物理显着性模式驱动的，还是由之前遇到类似场景而形成的内容驱动的偏见驱动的？我们进行了两项眼球追踪实验来解决这些问题。使用一种新颖的注视解码方法，我们表明注视模式可以预测自由探索期间的场景类别。此外，我们使用计算显着性图来隔离显着性驱动的贡献，并使用凝视限制注视数据来隔离内容驱动的贡献。我们发现显着性驱动和内容驱动的效果有不同的时间进程。身体显着性的影响最初达到顶峰，但在刺激开始后 600 毫秒迅速下降。内容效应的影响是偶然开始的，并在刺激开始后的 2000 毫秒内稳步增强。这两个组成部分的结合显着解释了自由探索过程中注视分配的时间过程。
Scene content is thought to be processed quickly and efficiently to bias subsequent visual exploration.Does scene content bias spatial attention during task-free visual exploration of natural scenes?If so, is this bias driven by patterns of physical salience or content-driven biases formed through previous encounters with similar scenes? We conducted two eye-tracking experiments to address these questions. Using a novel gaze decoding method, we show that fixation patterns predict scene category during free exploration. Additionally, we isolate salience-driven contributions using computational salience maps and content-driven contributions using gaze-restricted fixation data. We find distinct time courses for salience-driven and content-driven effects. The influence of physical salience peaked initially but quickly fell off at 600 ms past stimulus onset. The influence of content effects started at chance and steadily increased over the 2000 ms after stimulus onset. The combination of these two components significantly explains the time course of gaze allocation during free exploration.
