场景知觉及其研究范式

场景知觉关注的是人如何知觉和加工复杂的真实环境信息。场景包括物体和背景两个重要的组成部分，根据复杂性与真实性程度，场景刺激材料可以分为三种不同的类型。已有研究主要从自上而下和自下而上两种方式来解释场景知觉中信息的提取和加工，也有研究试图从二者交互的角度来进行解释。此外，基于不同的实验目的和技术，研究者分别采用了眼动、背景提示、物体觉察、变化觉察和点线索追随几种不同的研究范式来探讨场景信息的知觉问题。场景知觉研究在场景的定义、不同范式间的整合、研究内部效度和不同加工阶段的加工方式四个方面还需要进一步深入和探讨

Scene Perception and Its Research Paradigms

The main purpose of scene perception is to investigate how people perceive and process complex real-world scene information. Objects and background elements are the necessary parts of scene. Furthermore, according to the complexity and reality of the stimuli, meaningless figures or letters, sequences of objects, 3D pictures, and real-world environment could be used as stimuli in scene perception. Previous studies of scene perception mainly used top-down and bottom-up processing to explain the scene perception. Surprisingly, more and more researchers emphasize the interaction of top-down and bottom-up. Based on different purpose of experiments and techniques they used, researchers use different paradigms to study how we perceive and process scenes. These paradigms include eye movement, object detection, contextual cueing, change detection, and follow-the-dot. Further studies should pay more attention to definition of scene perception, relationship of different paradigms, internal validity, and processing patterns of different cognitive stages
