摘要:本研究探讨了视觉系统在视觉搜索任务的不同阶段如何利用上下文和任务信息。目标模板的特异性(目标图片或目标名称)与真实场景中目标位置的合理性进行正交处理。研究结果表明,目标模板信息和空间语境引导从场景观察开始就对眼球运动起到了引导作用。在搜索开始和随后的场景扫描中,当场景的空间背景具有误导性时,特定视觉模板的可用性特别有用,而可靠的场景背景的可用性主要在模板是抽象的情况下促进搜索。目标验证主要受目标模板的详细程度的影响,在图片提示的情况下更快。结果表明,视觉系统可以根据这两种高级来源提供的可用信息的数量和质量,从场景检测开始就灵活地利用目标模板引导和上下文引导。这允许在现实世界场景中搜索的不同阶段对动眼肌行为进行优化。
Abstract:Abstract This study investigated how the visual system utilizes context and task information during the different phases of a visual search task. The specificity of the target template (the picture or the name of the target) and the plausibility of target position in real-world scenes were manipulated orthogonally. Our findings showed that both target template information and guidance of spatial context are utilized to guide eye movements from the beginning of scene inspection. In both search initiation and subsequent scene scanning, the availability of a specific visual template was particularly useful when the spatial context of the scene was misleading and the availability of a reliable scene context facilitated search mainly when the template was abstract. Target verification was affected principally by the level of detail of target template, and was quicker in the case of a picture cue. The results indicate that the visual system can utilize target template guidance and context guidance flexibly from the beginning of scene inspection, depending upon the amount and the quality of the available information supplied by either of these high-level sources. This allows for optimization of oculomotor behavior throughout the different phases of search within a real-world scene.
