Interocular conflict attracts attentionChris L E Paffen
Helmholtz Institute and Experimental Psychology, Utrecht University, Heidelberglaan 2, Utrecht, The Netherlands
Atten Percept Psychophys 74:251-6. 2012..The results of a second experiment indicated that interocular conflict attracts attention during the first phase of presentation, a phase during which the stimulus is abnormally fused [added]...
The effect of set size on the dynamics of binocular rivalryChris L E Paffen
Helmholtz Institute and Experimental Psychology, Utrecht University, Heidelberglaan 2, 3584 CS Utrecht, The Netherlands
Seeing Perceiving 24:19-35. 2011..Our results show that the spatial distribution of attention affects the number of alternations reported in a rivalry-inducing display...- A search asymmetry for interocular conflictChris L E Paffen
Helmholtz Institute and Department of Experimental Psychology, Utrecht University, Heidelberglaan 2, Utrecht, The Netherlands
Atten Percept Psychophys 73:1042-53. 2011..In addition, we provide evidence for the suggestion that differences in search for interocular conflict are contingent on the degree of abnormal fusion of the dissimilar images... - Symbolic magnitude modulates perceptual strength in binocular rivalryChris L E Paffen
Experimental Psychology, Department of Psychology, Faculty of Social Sciences and Helmholtz Institute, Utrecht University, Heidelberglaan 2, 3584 CS, The Netherlands
Cognition 119:468-75. 2011..Our findings show that symbolic, acculturated knowledge about magnitude interacts with visual perception and affects perception in a manner similar to lower-level aspects of magnitude such as luminance contrast... - Shifting spatial attention makes you flip: Exogenous visual attention triggers perceptual alternations during binocular rivalryChris L E Paffen
Utrecht University, Utrecht, The Netherlands
Atten Percept Psychophys 72:1237-43. 2010..Furthermore, we suggest that an occipito-fronto-parietal network known to be involved in selective attention and binocular rivalry mediates perceptual alternations by boosting the neural response at attended locations... - The spatial origin of a perceptual transition in binocular rivalryChris L E Paffen
Helmholtz Institute and Experimental Psychology, Utrecht University, Utrecht, The Netherlands
PLoS ONE 3:e2311. 2008..Our results further show that stimulus parameters affecting the temporal dynamics during continuous viewing of rival images described in other studies, also affect the spatial origin of traveling waves during binocular rivalry... - Attention-based perceptual learning increases binocular rivalry suppression of irrelevant visual featuresChris L E Paffen
Helmholtz Institute, Division of Experimental Psychology, Universiteit Utrecht, Utrecht, The Netherlands
J Vis 8:25.1-11. 2008..Furthermore, our results add new evidence in support of the claim that mechanisms involved in visual attention and binocular rivalry overlap... - Orientation-tuned suppression in binocular rivalry reveals general and specific components of rivalry suppressionSjoerd M Stuit
Experimental Psychology, Helmholtz Institute, Utrecht University, The Netherlands
J Vis 9:17.1-15. 2009..Together, the results suggest there are two components to rivalry suppression: a general feature-invariant component and an additional component specifically tuned to the rivaling features... 
Center-surround inhibition and facilitation as a function of size and contrast at multiple levels of visual motion processingChris L E Paffen
Helmholtz Institute, Psychonomics Division, Utrecht University, Utrecht, The Netherlands
J Vis 5:571-8. 2005..In addition, we provide evidence that surround inhibition occurs at multiple levels of visual processing: Surround inhibition in motion processing is likely to originate from both monocular and binocular processing stages...- Center-surround effects on perceived speedMaarten J van der Smagt
Utrecht University, Helmholtz Institute, Experimental Psychology Division, Heidelberglaan 2, 3584 CS Utrecht, Netherlands
Vision Res 50:1900-4. 2010..Our results suggest that, at least for the lower velocity used, center-surround interactions affect perceived speed in a manner analogous to their effect on direction discrimination... - Time dilation in dynamic visual displayRyota Kanai
Universiteit Utrecht, Helmholtz Institute, Department of Experimental Psychology, Utrecht, The Netherlands
J Vis 6:1421-30. 2006..These results suggest that the clock governing perceived time has its basis at early processing stages. The possible links between models of time perception and neurophysiological functions of early visual areas are discussed... - Saliency in a suppressed image affects the spatial origin of perceptual alternations during binocular rivalrySjoerd M Stuit
Utrecht University, Neuroscience and Cognition Utrecht, Helmholtz Institute, Division of Experimental Psychology, Heidelberglaan 2, NL 3584 CS, Utrecht, The Netherlands
Vision Res 50:1913-21. 2010..Moreover, the finding that saliency affects the spatial origin of a perceptual alternation is in agreement with the idea that saliency is represented at a monocular, unconscious level of visual processing... - Attention speeds binocular rivalryChris L E Paffen
Experimental Psychology, Helmholtz Institute, Universiteit Utrecht, Utrecht, The Netherlands
Psychol Sci 17:752-6. 2006..This increase in effective contrast will ultimately lead to a perceptual switch, thereby limiting voluntary control. Thus, attention speeds rivalry alternations, but has no inherent control over the rivalry process... - Center-surround inhibition deepens binocular rivalry suppressionChris L E Paffen
Universiteit Utrecht, Helmholtz Research Institute, Psychonomics Division, Heidelberglaan 2, NL 3584 CS Utrecht, The Netherlands
Vision Res 45:2642-9. 2005..These results implicate a higher-level, fully binocular area whose surround inhibition provides an additional source of suppression which sums with rivalry suppression to effectively deepen suppression of an unseen rival target... - Center-surround interactions in visual motion processing during binocular rivalryChris L E Paffen
Psychonomics Division, Helmholtz Research Institute, Universiteit Utrecht, Heidelberglaan 2, NL 3584 CS Utrecht, The Netherlands
Vision Res 44:1635-9. 2004..We therefore suggest that this phenomenon is the outcome of center-surround interactions at multiple levels along the pathway of visual motion processing... - Blindness to inconsistent local signals in motion transparency from oscillating dotsRyota Kanai
Psychonomics Division, Universiteit Utrecht, Helmholtz Research Institute, Heidelberglaan 2, 3584 CS Utrecht, The Netherlands
Vision Res 44:2207-12. 2004..These findings suggest that when global visual representations are constructed, weak and inconsistent local signals are discarded... - What is Grouping during Binocular Rivalry?Sjoerd M Stuit
Division of Experimental Psychology, Helmholtz Institute, Neuroscience and Cognition Utrecht, Universiteit Utrecht Utrecht, Netherlands
Front Hum Neurosci 5:117. 2011.... - Centre-surround relative motion and the freezing rotation illusionAlexander H Wertheim
Helmholtz Institute and Department of Experimental Psychology, Utrecht University, Heidelberglaan 2, 3584 CS Utrecht, The Netherlands
Perception 38:1610-20. 2009..The amount of underestimation and overestimation of velocity is not related to the velocity difference between the centre and the surround. Some factors that may be relevant to the explanation of the illusion are discussed... - Adaptive center-surround interactions in human vision revealed during binocular rivalryChris L E Paffen
Helmholtz Research Institute, Psychonomics Division, Utrecht University Heidelberglaan 2, The Netherlands
Vision Res 46:599-604. 2006..This contrast-dependent modulation of center-surround interactions seems to be a general property of the visual system and may reflect an adaptive balance between surround suppression and spatial summation...
