Abstract: Considering scenes differ from other types of visual stimuli which have been chosen by previous papers in a number of important ways, it is still an open question whether there is an overall attentional bias of horizontal and vertical visual fields in viewing nature scenes. To answer this question, 40 university students(20 female) viewed 40 real-world pictures, allowed free viewing, and monitored eye movements. Our study revealed that there are leftward and upward attentional bias in viewing natural scenes. The present finding plays an essential role in driving, aviation, advertisement and other fields where visual attention is important for safety and efficiency.

摘要： 本研究采用眼动仪直接记录40名在校大学生及研究生（平均年龄21.9岁，SD=1.8）自由观看实景图片的眼动情况，考察自然状态下视觉注意在真实场景中的空间偏向。为了控制图片不同区域刺激特征显著性对结果的影响，将被试随机分为两组，一组观看正向图片，一组观看倒置图片。对图片四个象限上的首次注视概率、首次眼跳方向和注视时间百分比分别进行2（水平方向）×2（垂直方向）×2（呈现方式）的重复测量方差分析，结果表明，存在独立于刺激特征的空间注意偏向，表现在水平方向具有左侧注意偏向，垂直方向具有上侧注意偏向。
