Dissociating task performance from fMRI repetition attenuation in ventral visual cortexYaoda Xu
Department of Psychology, Yale University, New Haven, Connecticut 06520 8205, USA
J Neurosci 27:5981-5. 2007..Thus, although repetition attenuation and performance are often correlated, they can be dissociated, suggesting that attenuation in ventral visual areas reflects stimulus-specific processing independent of task demands...- The role of the superior intraparietal sulcus in supporting visual short-term memory for multifeature objectsYaoda Xu
Department of Psychology, Yale University, New Haven, Connecticut 06520 8205, USA
J Neurosci 27:11676-86. 2007..These results also bring new understanding to the object benefit reported in behavioral VSTM studies and provide new insights into solving the binding problem in the brain... - Visual short-term memory benefit for objects on different 3-D surfacesYaoda Xu
Psychology Department, Yale University, New Haven, CT 06520 8205, USA
J Exp Psychol Gen 136:653-62. 2007..This increment in capacity indicates that VSTM benefits from the placement of objects in a 3-D scene... - Understanding the object benefit in visual short-term memory: the roles of feature proximity and connectednessYaoda Xu
Vision Sciences Laboratory, Psychology Department, Harvard University, USA
Percept Psychophys 68:815-28. 2006..Together, these results indicate that location/proximity and connectedness are essential elements in defining a coherent visual object representation in VSTM... - Dissociable neural mechanisms supporting visual short-term memory for objectsYaoda Xu
Department of Psychology, Yale University, New Haven, Connecticut 06520 8205, USA
Nature 440:91-5. 2006..VSTM capacity is therefore determined both by a fixed number of objects and by object complexity... - The M170 is selective for faces, not for expertiseYaoda Xu
Psychology Department, Yale University, Box 208205, New Haven, CT 06520 8205, USA
Neuropsychologia 43:588-97. 2005..These results indicate that the early face processing mechanisms marked by the M170 are involved in the identification of faces in particular, not in the identification of any objects of expertise... - Revisiting the role of the fusiform face area in visual expertiseYaoda Xu
Department of Psychology, Yale University, New Haven, CT 06520 8205, USA
Cereb Cortex 15:1234-42. 2005..These results are consistent with those of Gauthier et al., and suggest the involvement of the right FFA in processing non-face expertise visual stimuli... 
Representing connected and disconnected shapes in human inferior intraparietal sulcusYaoda Xu
Department of Psychology, Yale University, New Haven, CT 06520 8205, USA
Neuroimage 40:1849-56. 2008..Assuming that a lower response corresponds to a greater ease of representation, these results may explain why after parietal brain lesions grouped visual elements are easier to perceive than ungrouped ones...
Visual grouping in human parietal cortexYaoda Xu
Department of Psychology, Yale University, New Haven, CT 06510, USA
Proc Natl Acad Sci U S A 104:18766-71. 2007..These results are discussed within a neural object file framework, which argues for distinctive neural mechanisms supporting object individuation and identification in visual perception...- Selecting and perceiving multiple visual objectsYaoda Xu
Department of Psychology, Harvard University, 33 Kirkland Street, Room 780, Cambridge, MA 02138, USA
Trends Cogn Sci 13:167-74. 2009..It provides a better understanding of the role of the different parietal areas in encoding visual objects and can explain various forms of capacity-limited processing in visual cognition such as working memory... - The neural fate of task-irrelevant features in object-based processingYaoda Xu
Department of Psychology, Harvard University, Cambridge, Massachusetts 02138, USA
J Neurosci 30:14020-8. 2010..Object-based processing for task-irrelevant features of attended objects thus does exist, as reported previously; but it is transient and its magnitude is determined by the encoding demand of the task-relevant feature... - Object ensemble processing in human anterior-medial ventral visual cortexJonathan S Cant
Vision Sciences Laboratory, Department of Psychology, Harvard University, Cambridge, MA 02138, USA
J Neurosci 32:7685-700. 2012..These results provide the first step toward understanding the neural underpinnings of real-world object ensemble representation... - Distinctive neural mechanisms supporting visual object individuation and identificationYaoda Xu
Yale University, USA
J Cogn Neurosci 21:511-8. 2009..These results provide independent confirmation supporting the dissociation between visual object individuation and identification in the brain... - Feature integration across parts in visual searchYaoda Xu
Vision Sciences Laboratory, Department of Psychology, Harvard University, 33 Kirkland Street, Room 744, Cambridge, MA 02138, USA
Perception 31:1335-47. 2002..The formation of object part representations thus influences how features are integrated and encoded during visual information processing... - Early computation of part structure: evidence from visual searchYaoda Xu
Psychology Department, Harvard University, Cambridge, Massachusetts 02138, USA
Percept Psychophys 64:1039-54. 2002..Together, these results demonstrate that the visual system segments shapes into parts, using negative minima of curvature, and that it does so rapidly in early stages of visual processing... - Encoding color and shape from different parts of an object in visual short-term memoryYaoda Xu
Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA
Percept Psychophys 64:1260-80. 2002..An object-based feature binding therefore exists even when the color and shape features to be remembered are from different parts of an object... - Limitations of object-based feature encoding in visual short-term memoryYaoda Xu
Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, USA
J Exp Psychol Hum Percept Perform 28:458-68. 2002..These results thus impose a major constraint on object-based feature encoding theories by showing that only features from different dimensions can benefit from object-based encoding...
