Fusion Prevents the Redundant Signals Effect: Evidence from Stereoscopically Presented Stimuli
Schroter, Hannes; Fiedler, Anja; Miller, Jeff; Ulrich, Rolf
Journal of Experimental Psychology: Human Perception and Performance, v37 n5 p1361-1368 Oct 2011
In a simple reaction time (RT) experiment, visual stimuli were stereoscopically presented either to one eye (single stimulation) or to both eyes (redundant stimulation), with brightness matched for single and redundant stimulations. Redundant stimulation resulted in two separate percepts when noncorresponding retinal areas were stimulated, whereas it resulted in a single fused percept when corresponding areas were stimulated. With stimulation of noncorresponding areas, mean RT was shorter to redundant than to single stimulation, replicating the redundant signals effect (RSE) commonly found with visual stimuli. With stimulation of corresponding areas, however, no RSE was observed. This suggests that the RSE is driven by the number of percepts rather than by the number of stimulated receptors or sensory organs. These results are consistent with previous findings in the auditory modality and have implications for models of the RSE. (Contains 3 figures, 1 table and 3 footnotes.)
