[Purpose] Spatial layouts can be obtained implicitly as has been shown by contextual cuing effect (CCE). We investigated contextual cuing effect for spatial layout around us including the layouts in the rear. That is, we examined whether a learned spatial layout in a front display cues the target in a rare display, using the visual search in the stimulus presented on the displays surrounding the participant (360° visual field). [Experiment] We investigate implicit learning of spatial layouts using a CCE experiment. The CCE is a learning effect of spatial layout in visual search displays. Visual search performance increases by repeating visual search in the same layouts, without noticing the repetitions. We investigated the CCE for layouts presented in a 360° display and examined whether spatial layouts in front influence the detection of targets in the rear (CCE for target outside the visual field). Analyzing the reaction time for target detection separately for the time required to reach the display with the target and the time required to detect the target within the display, the CCE for the location of the target display would be isolated from the CCE for the target location within the display. [Results] We found CCEs for the location of target displays in the rear in addition for the target location within the display. Target detection of repeated layouts were shorter than that of new layouts independently of the location of target display and a part of the shortening was for reaction time to reach the target display. This suggests that the visual system can learn implicitly association between the layout in front and the target location in the rear. [Discussion] Our results suggest that the visual system learns spatial layout implicitly around oneself including the information in the rear.
