The visual inspection of scenes is disrupted when participants are forced to begin inspection away from the centre of an image. The present study explored the effect of the starting point on the visual inspection of paintings. Eye movements were recorded while participants viewed paintings for later identification in a yes/no discrimination task. The viewing of each painting was preceded by the presentation of a pseudo-randomly positioned Navon figure. Participants were instructed using a cue to attend to either the local or global level of the Navon figure. Each painting was split into regions of interest (ROIs) defined by face, theme, and context to allow the analysis of eye movements. These data were directly compared with a subset of those initially reported in our previous study in which the same experiment was run but without the inclusion of the Navon figure. The inclusion of the Navon task lowered the discrimination accuracy in the yes/no discrimination task. More importantly, eye movements to the paintings were disrupted across the entire period over which they were viewed and not just in the period following the offset of the Navon figure. The results show the sensitivity of eye movements to the conditions present at the beginning of viewing. The results have implications for the viewing of paintings (and other images) in the real world, where the starting conditions for inspection cannot be controlled.
当参与者被迫从图像中心以外的位置开始检查时，场景的视觉检查会受到干扰。本研究探讨了起始点对绘画视觉检查的影响。在参与者观看绘画以便在是/否辨别任务中进行后续识别时，记录他们的眼动。在观看每幅画之前，会呈现一个伪随机定位的纳冯图形。通过提示指导参与者关注纳冯图形的局部或整体层面。每幅画被划分为由面部、主题和背景定义的感兴趣区域（ROI），以便分析眼动。这些数据与我们之前研究中最初报告的一部分数据直接进行比较，在之前的研究中进行了相同的实验，但没有纳入纳冯图形。纳入纳冯任务降低了是/否辨别任务中的辨别准确性。更重要的是，在观看绘画的整个时间段内，眼动都受到了干扰，而不仅仅是在纳冯图形消失后的时间段。结果表明眼动对观看开始时的条件很敏感。这些结果对现实世界中绘画（和其他图像）的观看具有启示意义，在现实世界中，检查的起始条件无法控制。
