Separating Fusion from Rivalry

Stefan M. Kallenberger, Constanze Schmidt, Peter Dechent, Clemens Forster, Nicole von Steinbüchel, Torsten Wüstenberg, Hans Strasburger, Samuel G. Solomon
2014 PLoS ONE  
Comparing BFR stimuli with BF and BR stimuli, respectively, we were able to disentangle brain responses associated with either visual fusion or rivalry.  ...  Visual fusion is the process in which differing but compatible binocular information is transformed into a unified percept.  ...  setup and the accomplishment of fMRI measurement.  ...

Binocular rivalry occurs without simultaneous presentation of rival stimuli

Robert P. O'shea, Boris Crassini
1984 Perception & Psychophysics  
Concentric with the gratings were four equally spaced, fine, white fusion rings. The inner ring had a diameter of 5.05 deg, and the outer a diameter of 6.42 deg.  ...  Werner (1940) mentioned binocular rivalry between a ring and a disk with alternate exposures separated by less than about 50 msec.  ...  It would require that rivalry and stereopsis be measured in a factorial design formed by the crossing of a range of variations of interocular delay between presentations of the dichoptic stimuli, and a  ...

Bradley N. Jack, Urte Roeber, Robert P. O'Shea, Nicholas Seow Chiang Price
2017 PLoS ONE  
Next, we changed one of the gratings to match the grating shown to the other eye, yielding binocular fusion.  ...  Participants perceived the rivalry-to-fusion change to the dominant grating and not to the other, suppressed grating.  ...  Luck and Emily S.

Composite binocular perception from dichoptic stimulus arrays with similar ensemble information

Oakyoon Cha, Randolph Blake, Sang Chul Chong
2018 Scientific Reports  
Using binocular rivalry as a proxy index, we found that composite perception of dichoptic arrays was more stable when the stimulus items shared similar colours, and that unusual ensembles induced binocular  ...  rivalry.  ...  Acknowledgements Author Contributions All authors conceived the research and designed the Experiments, O.C. conducted the Experiments, and all authors analysed the results.  ...

Predicting Visual Consciousness Electrophysiologically from Intermittent Binocular Rivalry

Robert P. O'Shea, Jürgen Kornmeier, Urte Roeber, Lawrence M. Ward
2013 PLoS ONE  
This display yields binocular rivalry: irregular alternations in visual consciousness between the images viewed by the eyes.  ...  Each participant also responded to numerous non-rivalry trials in which the gratings had identical orientations for the two eyes and for which the orientation of both either changed physically after the  ...  Acknowledgments We are grateful to Erich Schröger who supported this research and who commented helpfully on previous drafts of the paper, to Michael Bach who encouraged the research, and to Inka Bretschneider  ...

On the relation between dichoptic masking and binocular rivalry

Daniel H. Baker, Erich W. Graf
2009 Vision Research  
These findings are consistent with varying the magnitude of interocular suppression in computational models of both rivalry and masking, and imply the existence of a common suppressive process.  ...  Since dichoptic masking has been localised to the monocular neurons of V1, this is a plausible first stage of binocular rivalry.  ...  Acknowledgments We are grateful for the comments of two anonymous reviewers, and thank Jan Brascamp for comments on the manuscript and both him and Tomas Knapen for helpful discussions.  ...
