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.
