To interact with the world, we have to make sense of the continuous sensory input conveying information about our environment. A recent surge of studies has investigated the processes enabling scene understanding, using increasingly complex stimuli and sophisticated analyses to highlight the visual features and brain regions involved. However, there are two major challenges to producing a comprehensive framework for scene understanding. First, scene perception is highly dynamic, subserving multiple behavioral goals. Second, a multitude of different visual properties co-occur across scenes and may be correlated or independent. We synthesize the recent literature and argue that for a complete view of scene understanding, it is necessary to account for both differing observer goals and the contribution of diverse scene properties.
为了与世界互动,我们必须理解持续不断的感官输入,这些输入传达着有关我们环境的信息。最近大量的研究调查了实现场景理解的过程,使用了越来越复杂的刺激和精细的分析来突出所涉及的视觉特征和脑区。然而,要建立一个全面的场景理解框架存在两个主要挑战。第一,场景感知是高度动态的,服务于多个行为目标。第二,众多不同的视觉属性在场景中同时出现,可能相互关联或相互独立。我们综合了近期的文献,并认为要全面理解场景,有必要考虑不同的观察者目标以及各种场景属性的作用。
