Abstract: The current work examined the shift of spatial attention between the upper and lower visual fields and whether the attentional shift is influenced by perceived three-dimensional space. Posner′s cueing paradigm and two sets of visual context were used that produced perceived depth. Reaction times were measured in valid, invalid, and neutral conditions. We found that reaction latency was shorter in the valid conditions than that in invalid ones and this effect was stronger when stimuli were presented in upper visual fields than that in the lower ones. However, attentional shift between the upper and lower visual fields was not affected by perceived depth. The results suggest an asymmetry of the attentional shift between the upper visual fields and lower ones.

Key words: perceived space, visual field, attentional shift, cueing paradigm
