Binocular rivalry (BR) offers a window into how perception is constructed, shaped by spatial and temporal context cues. Spatial context is often provided in form of a surrounding annulus, and a widely used type of temporal influence is flash suppression in which a stimulus shown prior to the BR-stimulus biases its perception. While these types of contexts have been individually studied, their combined effects have not yet been explored. We investigated spatial-temporal context interactions during rivalry in two experiments. Using orthogonal gratings as rivalry stimuli, we manipulated spatial surround strength through contrast changes and flash suppression strength by varying the blank duration (Experiment 1, N = 17) and probe durations (Experiment 2, N = 17). We measured both the dominant percept as well as its clarity. Using each type of context alone confirmed previous findings. However, combining spatial and temporal factors revealed the following additional insights: when both contexts favored the same grating, the effects were additive. When spatial and temporal context favored different gratings, the influence of the spatial context dominated. Clarity ratings differed across experiments, revealing differences between the two manipulations of the temporal effect. Our results demonstrate that temporal and spatial contextual factors can have a cumulative effect when they align and that spatial context tends to prevail in conflicting situations. This underscores the critical role of spatial context in visual perception.
